In 1970, the National Roofing Foundation (Foundation) was formed as the National Roofing Contractors Association’s (NRCA’s) educational and research foundation. In 1996 the Roofing Industry Alliance for Progress (The Alliance) was created within the Foundation as a forum for leaders from all segments of the industry to address current and future issues and to create a permanent endowment fund. The Alliance continues to be a diverse, thoughtful and dedicated forum of roofing contractors, manufacturers, distributors, service providers and industry professionals united to shape, improve and advance the roofing industry.

The Alliance meets twice a year to conduct member business; hear updates on current projects and programs; analyze and select new projects that are proposed for funding; hear speakers from within and outside the industry; and to network with fellow Alliance members.

The Alliance currently has 165 members. This group of committed leaders has contributed over $13 million to the Alliance’s endowment fund to help preserve and enhance the U.S. roofing industry’s success by funding industry research, providing timely and forward-thinking industry responses to major economic and technological issues, and helping to promote professionalism and increasing awareness about career opportunities within the roofing industry.

To date, the Alliance has allocated a little over $5.3 million in funding to 46 different projects, programs and studies to help better the industry.

The Alliance has four areas of focus: philanthropy; education; workforce and training; and technology and research.

Philanthropy

The Alliance’s philanthropic efforts include:

  • The Helping Our Own Program, which includes reaching out to the roofing community and its members and helping fund efforts dedicated to good works and charitable giving. Through a nomination process, The Alliance can recognize and

    identify the challenges associated with these life-changing events and help create sustainable solutions for individuals or families in need. Although The Alliance may not be able to solve all the problems rendered during a time of crisis, collectively, we can make a real difference in the lives of families who may fall victim to tragedy.

  • The Most Valuable Player Awards (MVP) Program provides an opportunity for companies to nominate their most outstanding roofing field workers or warehouse workers who not only excel within their companies but go above and beyond to make a difference in their communities. Since the program’s inception, 632 employees have been nominated and 234 winners and finalists have been selected. A maximum of 10 winners are selected by members of the Alliance’s MVP Task Force. The winners receive an expense-paid trip to NRCA’s annual convention and are recognized at NRCA’s Industry Awards Ceremony and Cocktail Reception. Details for the 2018-19 MVP Program will be available in September 2018.
  • The Gold Circle Awards program recognizes Alliance and NRCA member firms for their outstanding contributions to the roofing industry through outstanding workmanship, innovative solutions and safety preparedness and performance. Winners, selected by the Alliance’s Gold Circle Awards Committee, are also recognized at NRCA’s Industry Awards Ceremony.
  • The Alliance’s newest initiative is a partnership with Ronald McDonald House Charities (RMHC). RMHC is operated with the support of McDonald’s Corp., headquartered in Chicago. Each of their 165 stand-alone houses is independently owned and operated, and all are established as 501(c)(3) corporations. The core purpose of each house is to provide a home for family members of children who are being treated at a hospital. The houses provide private sleeping rooms, food and pride themselves on offering opportunities for families to interact as they go through their difficult times.

In addition to providing roof and building maintenance, volunteers help Ronald McDonald House Charities in a variety of ways. Pictured here are volunteers at Camp Ronald McDonald for Good Times, Mountain Center, California. Photos: The Roofing Industry Alliance for Progress

Alliance and NRCA members adopting houses in their areas are asked to conduct annual roof inspections, ensure the roofs are properly maintained and perform emergency roof repairs when needed. Roof replacements will be managed as individual projects, and, when appropriate, several contractors may be asked to participate. We’ll reach out to our manufacturer and distributor members to see if they can assist with donated products and materials. In addition to providing roof maintenance, there are a number of volunteer opportunities for the members’ employees. Volunteers are welcome to prepare meals, bake special treats, clean, paint, etc.

Currently 90 out of the 165 stand-alone houses have been adopted. Alliance President Rod Petrick issued a challenge to Alliance and NRCA members that he would like to see all 165 houses adopted by the Fall, 2018 Alliance meeting.

Education

On the education front, the Alliance partners with Construction Management Schools, provides scholarships and is a Diamond sponsor of National Women in Roofing.

We’re working with construction management schools across the country to (1) raise awareness of our industry among students and faculty; (2) encourage the schools to integrate more roofing-specific materials into their course curricula; and (3) encourage students to consider our industry as a viable career option.

The Alliance sponsors design competitions for construction management students. Pictured here is the first-place team from Auburn University’s McWhorter School of Building Sciences at the. 2018 International Roofing Expo in New Orleans. Photos: The Roofing Industry Alliance for Progress

A great way to reach construction management students is through design competitions. We’ve had four so far and we’re currently working on our fifth. The competition challenges the students’ roofing knowledge, construction management skills, time management, organizational and presentation skills. The finalist teams and faculty come to the convention to give their oral presentations. While there, they also opportunities to meet members and to learn more about our industry by attending the educational sessions and the expo.

The next step in our partnership with construction management schools is to find ways to connect with faculty. Our plan is to do this through a research project recently approved at the April, 2018 Alliance member meeting, “A Study of the U.S. Roofing Industry and Its Workforce.” This demographic study will quantify the economic impact of the roofing industry and measure the size, age, racial background and gender of the workforce. It also will identify the number of roof contracting, manufacturing and distribution companies that exist in the U.S. market and the type of work they do. This comprehensive study will provide real data for us as we plan our future.

The Alliance awards $55,000 annually in scholarship funds through the Melvin Kruger Endowed Scholarship Program, which is open to employees and family members of NRCA member firms who are pursuing careers in the roofing or building construction industries. Since the program’s inception, a total of $790,000 has been awarded to 125 students.

The Alliance is also a Diamond sponsor for National Women in Roofing, which is dedicated to educating, mentoring and supporting women in the various roles they fill within the roofing industry.

Workforce and Training

The Alliance continues its efforts to elevate the roofing industry under the current leadership team that includes (from left) Alliance Vice President Josh Kelly of OMG Roofing Products, Agawam, Massachusetts; Alliance President Rod Petrick of Ridgeworth Roofing Co. Inc., Frankfort, Illinois; Immediate Former Alliance President Thomas Saeli of Duro-Last Inc., Saginaw, Michigan. Photos: The Roofing Industry Alliance for Progress

The Alliance supports several workforce and training initiatives. Previously the Alliance partnered with Bilingual America on a cultural and leadership training program for Alliance-member firms that employee Latino workers. And, more recently, the Alliance provided funding to help with the development of NRCA’s ProCertification Series.

Technology and Research

On the technology and research front, the Alliance funded:

  • NRCA’s EnergyWise online calculator. Originally funding was provided to help develop the program; later funding was approved to provide program updates.
  • A study to better understand the moisture release in concrete roof decks. A final report will be available this fall.
  • NRCA’s Silica Objective Data Collection Study.

Over the next 12 months, The Alliance will be working with an outside marketing and communications firm to ramp up marketing efforts, making the sure the industry knows who The Alliance is and is aware of all that the Alliance is doing. Hopefully as we create more awareness, more project funding requests will be generated. And, of course, we work to continue to grow the Alliance with new members, but equally important — we want to make sure our current members stay actively engaged and involved.

Member involvement is key. The Alliance can only continue in its efforts if members remain actively involved every step of the way. It will be exciting to see what the new year brings under the leadership of Alliance President Rod Petrick. Rod’s passion, energy and drive are contagious. As president, he will see to it that The Alliance continues to be imaginative, intelligent and bold so that working together we can help The Alliance reach its full potential!

Contractor Conquers Tough Weather, Tight Schedule

Goodman, an international commercial and industrial property group, approached Donald B. Smith Inc. of DBS Roofing in November 2017 to support the roofing of the company’s new Logistics Center in central Pennsylvania.

Founded in 1948, DBS Roofing is a second-generation, privately held company whose principles of quality and workmanship have earned the team countless awards. Among those honors include the Firestone Master Contractor recognition, the Baltimore Builder’s Exchange “Craftsman of the Year Award” and numerous industry publication recognitions for notable projects.

The Logistics Center roof was 1,010,000 square feet and was established on a very aggressive timeline that spanned through the tough Northeast winter months. The initial specifications of the job called for a mechanically fastened TPO roof system, which was going to be challenging with the size and timeline of the project. Additionally, the condensation levels in central Pennsylvania are not ideal for mechanically fastened solutions, as it would require applying a vapor barrier and foam around all perimeters, exceeding the original budget and schedule.

To save time and keep the project moving forward during the unfavorable winter conditions, DBS Roofing elected to use one of the company’s favorite “box world” solutions — Firestone Building Products (FSBP) UltraPly TPO SA with Secure Bond Technology.

The TPO roofing system is comprised of a self-adhering membrane with factory applied, pressure sensitive adhesive and technology designed to ensure uniform adhesion coverage across the entire membrane. According to the manufacturer, the system can be installed in weather as cold as 20 degrees Fahrenheit.

“Commercial roofing in central Pennsylvania can be very challenging during the winter season, but Firestone UltraPly TPO SA allows our business to continue working through those conditions and prosper,” says Donnie Sanders, president of construction, DBS Roofing. “Being able to apply the Firestone TPO SA at 20 degrees resulted in a successful year for us.”

The Goodman Logistics Center roofing project began on November 1, 2017 and was completed on time March 1, 2018.

New Roof Helps Maintenance Facility Live on as Transportation Museum

Originally built in the 1930s to serve as a maintenance facility for electric-powered cable cars and train cars, the Interurban Electric Railway Bridge Yard Shop (IERBYS) is now a transportation museum for the Oakland to San Francisco Bay Bridge. Photo: CertainTeed

A transportation museum located along the Bay Bridge Trail in Oakland’s Gateway Park required roofing with a classic look plus the benefits of modern materials to protect its exhibits far into the future.

Built in Oakland, California, in the 1930s as a maintenance facility for electric-powered cable cars and train cars, the Interurban Electric Railway Bridge Yard Shop (IERBYS) was transformed into a transportation museum for the Oakland to San Francisco Bay Bridge that opened in 2013.

Due to the IERBYS being a historic landmark, the installing contractor — Westech Roofing of Richmond, California — was required to have the building exterior match the same look the building presented when it was first constructed, as documented by historic photos of the building available through the Library of Congress.

Classic Look, Modern Materials

The original roof was a hot-process built-up roof, and considerations were given to try to match that look by installing a hot asphalt roof system. However, because of factors such as roof access, wind from the bay, and number of times the kettle would need to be moved to access the structure’s 17 separate roof decks, the decision was made to use a different application method.

Photo: CertainTeed

The contractor chose CertainTeed’s Flintlastic SA self-adhered modified bitumen system along with SmartFlash liquid flashing to overcome the project’s challenges and replicate the look that was required by the client. The three-ply system consists of Flintlastic SA Nailbase, Flintlastic SA Midply and Flintlastic SA Cap FR Capsheet.

Another challenge for the Bay Bridge Museum was completing the roof flashing. On each of the numerous roof decks there were locations where the roofing needed to be flashed to the siding on the outside of the building. However, the siding is constructed of asbestos panels, which required the Westech Roofing team members to complete the roof flashing without disturbing the panels. In order to accomplish this task, they used CertainTeed’s SmartFlash liquid flashing with excellent results.

Commercial Roofing Contractor Flexes Its Muscles on 1.3 Million-Square-Foot Project

Industrial projects exceeding one million square feet of roofing might give some contractors pause, but at Orndorff & Spaid Roofing Inc., it’s just another day at the office.

The third-generation family run roofing contractor has been in business since 1953. Orndorff & Spaid services the Baltimore-Washington metro area, as well as parts of Virginia, Pennsylvania, and Delaware. It focuses primarily on large-scale commercial projects, including warehouses, distribution centers, retail businesses, schools and data centers.

Orndorff & Spaid routinely tackles roofing projects up to 1.5 million square feet. The company strives to keep as much work as possible under its own control, and the necessary supplies and equipment are always on hand at its 13-acre headquarters in Beltsville, Maryland.

“We’re a little bit unique as a roofing company in that we self-perform almost everything,” says Richard Harville, vice president of estimating. “We have our own cranes, all our own lifts. We do our own trucking. We have an in-house mechanic’s shop that repairs all of the equipment. All fuel servicing is done from our yard here. We also warehouse a fair share of material here because the logistics of running a job.”

Photo: Johns Manville

A recent new construction project at the former location of a Bethlehem Steel factory in Tradepoint St. John’s was right up their alley. “This was a new construction project, fairly conventional in most regards except for one, and that had to do with the site,” notes Harville. “Most of the site had been infilled over the years, and there was a lot of slag and other materials on this site, so it is not bedrock, for sure.” Due to the potential for movement, seismic expansion joints were specified. The gaps in the deck were as wide as 9 inches.

The owner of the complex was kept under wraps during construction phase, but the completed Under Armour distribution warehouse is now an area landmark. The roof encompasses 1,286,000 square feet, and the project had to be completed under a very tight schedule.

The general contractor on the project, FCL, reached out to Orndorff & Spaid during the design phase, and they recommended a TPO roof system manufactured by Johns Manville.

Harville shared his insights on the project with Roofing, along with members of the project team including Dane Grudzien, estimator; Carl Spraker, project manager, single ply; and Mike McKinney, project manager, sheet metal.

The Clock Is Ticking

Work began in April 2017 with a deadline to finish by the end of July. “The schedule was what made this project difficult,” notes Harville. “They had an end user set to come in and they were in an extreme hurry to get this thing done.”

Workers outside the safety perimeter were tied off 100 percent of the time using AES Raptor TriRex Safety Carts. Photo: Orndorff & Spaid Roofing Inc.

Harville and Spraker were confident the experienced team would be up to the task. “Once we got our bearings, we rock and rolled this job,” Spraker says. “We had up to 40 employees on the site and worked six days a week.”

The roof system installed over the structure’s metal deck included two layers of 2.5-inch polyiso and a 60-mil TPO membrane. “This job was mechanically attached at 6 inches on center, with perimeter and corner enhancements as required by FM,” notes Grudzien.

The roof installation began with a 10-man crew, and crews were added as the work ramped up. “We ended up with four 10-man crews, with the foreman on the first crew in charge the team,” Spraker recalls. “We just did as much as we could every day and kept track of everything. We averaged 700 squares a day. One day we did 1,000 squares.”

Crews worked on half of the building at a time, with falling back as needed to install flashings or strip in the gravel stop. “We started on one side of the building and went from end to end, following the steel contractor,” says Spraker. “When we finished one side, we came all the way back to the end where they started and followed them down the opposite side.”

The roof also incorporated 276 VELUX skylights to illuminate key areas of the facility. Logistics Lighting delivered them all in one shipment, as Orndorff & Spaid requested. The 4-foot-by-8-foot skylights were stored on site and loaded to the roof with a crane for installation after a plasma cutter was used to cut holes in the deck. Prefabricated curbs were installed and flashed. “I had a separate crew designated just to install skylights,” Spraker notes

Safety precautions included perimeter warning lines, and workers outside that area were tied off 100 percent of the time, as they were when the skylights were installed. AES Raptor TriRex Safety Carts were used as anchor points.

Safety is always crucial, notes Harville, and the company makes it a priority on every project. “Our safety parameters go above and beyond standard state or federal mandating,” he notes.

Metal Work

The scope of work included large external gutters, downspouts and edge metal. According to McKinney, the sheet metal application was pretty straightforward. “There was just a lot of it — long, straight runs down two sides,” he says. “The coping was installed on the parapets on the shorter ends.”

Gutters were installed after the roof system was in place. “The roof wasn’t 100 percent complete, but once areas of the roof were installed and the walls were painted white, we could begin to install the gutters,” says McKinney. “After work was completed on one side, crews moved to the other side.”

The large gutter featured internal and external hangers, alternating 36 inches on center. All the metal was fabricated in house, and the exterior hangers were powder coated to match the steel.

Once the external hangers were installed, the gutter sections were lowered into place and secured by crew members in a man lift. “Once you had your hangers up, you could just lower the gutter over the side and into the external hangers,” McKinney explains. “We put the internal hangers into place after that. After the drip edge is installed, the single-ply crews come back and flash the drip edge into the roof system.”

Downspouts were custom-designed to match the building’s paint scheme. Photo: Orndorff & Spaid Roofing Inc.

Installation of the downspouts had to wait until the walls were painted. One wrinkle was the change in color of the downspouts. About two-thirds of the way up the wall, the paint scheme went from black to white, and the building owner wanted the downspouts to change colors to match. “We reverse-engineered it,” notes McKinney. “We measured from the paint line up and put in a 30-foot section of downspouts there, because we put our bands at the joints and we didn’t want to have the bands too close together in the middle of the wall.”

Talented Team

The project was completed on budget — and a month early. FCL hosted a barbecue to celebrate. “FCL had a big cookout for the contractors with a steak dinner for everyone,” notes Harville. “They really went over and above on that.”

The Orndorff & Spaid team credits the effort of all companies involved for the success of the project. “The steel contractor was phenomenal, and FCL did an excellent job of coordinating everything,” Spraker says.

The manufacturer also did an excellent job, notes Harville, who commended the work of Melissa Duvall, the JM sales rep on the project, and Barney Conway, the field rep, who visited the site at least once a week. “JM did a good job keeping us well stocked with material and getting us deliveries when we needed them,” Harville notes.

The team members at Orndorff & Spaid believe their confidence comes from experience and knowing that most of the variables are under control. “A lot of that has to do with the equipment we can bring to bear when we need to,” Harville states. “We control the logistics all the way through. Most companies are going to rent a crane or hire trucking — we do all of that. We have our own lifts, we have our own cranes, we do all of our flatbed trucking. We bring a unique process to the table. Beyond that, and our project managers are well versed at doing this. It’s not our first rodeo.”

Roofing Project Keeps Arizona Warehouse Chill

When the original built-up roof on Hensley Beverage Company’s Tucson warehouse was failing, it was topped with a sprayed-in-place polyurethane foam roof system and an acrylic elastomeric protective coating. Photos: Rain Man Roofing

What do Landshark Lager, Stella Artois, 3 Amigos Tequila, Nesquik, and Sunny Delight have in common? All are products distributed by Arizona-based Hensley Beverage Company. And all are favorites of Rain Man Roofing, the contractor that repaired a 100,000-square-foot warehouse roof at Hensley’s Tucson location.

Hensley Beverage Company began in 1955 when Jim Hensley, starting with just 15 employees, delivered 73,000 cases of ice-cold Anheuser-Busch beer to thirsty Phoenix residents. Fast-forward to 2018 and Hensley is among the largest family-owned and -operated beverage distribution firms in the United States.

Today, under the leadership of CEO Robert Delgado, President Andrew McCain and Chairman of the Board Cindy McCain, Hensley Beverage Company is a 30-million-case wholesaler. Cindy McCain is the daughter of company founder Jim Hensley and wife of U.S. Sen. John McCain (R-Arizona). Andrew McCain is the senator’s son from a previous marriage.

The company operates a service fleet of more than 1,100 delivery vehicles and employs more than 1,200 people. Delivery now extends beyond Phoenix into every corner of Arizona. Trucks regularly deliver over 2,500 different beverages to thirsty desert dwellers, including domestic, imported, and craft beers, spirits, wine and non-alcoholic beverages of all sorts.

Beverages like these have to be refrigerated in a climate-controlled distribution warehouse while they are being stored. Some kegs need to be stored at 34 to 38 degrees Fahrenheit. Other products can get by at higher temperatures ranging from 45 to 60 degrees.

But the warehouse can’t control the environment efficiently with a leaky roof. That’s where Rain Man Roofing owner Mark Hughes came in.

Rain Man Roofing, founded in 2010, is one of the highest rated roofing specialists in both Arizona and California. In 2011, Rain Man became a BBB Accredited Business with an A+ rating, which it has consistently maintained. With more than 25 years of experience in the roofing industry, Rain Man is well known for inspecting every roofing solution at both the beginning and end of a job — and providing detailed status reports throughout the entire process.

Rain Man to the Rescue

In early 2018, Hensley’s VP of Fleet and Facilities Anthony Keffer contacted Hughes about roof issues at Hensley’s Tucson facility. Hughes’ roofers had, in September 2017, successfully stopped a leaking roof at another Hensley building in Flagstaff with a simple and affordable restoration solution, so Keffer asked Hughes to take a look at the Tucson site.

Crews from Rain Man Roofing completed work on the nearly 100,000-square-foot section of the warehouse roof in just three weeks. Photos: Rain Man Roofing

Several attempts to fix the roof in-house had failed to solve the problem. But Hughes and Rain Man, along with Erin Easter of Icynene-Lapolla, suggested a re-roof using a roof system of sprayed-in-place polyurethane foam and an acrylic elastomeric protective coating. Hensley accepted the proposal and work on the nearly 100,000-square-foot warehouse roof began.

Hensley inherited the 20-plus-year-old, low-sloped roof of the Tucson distribution facility in January 2016 when the company acquired Anheuser-Busch InBev wholesaler Golden Eagle Distributors Inc. The roof itself consisted of a UV-coated built-up, smooth-surfaced modified roof system over lightweight concrete. The old roof also included a cardboard separator installed between the concrete and a corrugated metal roof deck.

By 2018, the laps in the roof’s membrane no longer functioned properly and roof system failure became increasingly frequent. The lap failures, most likely caused by improper installation and deterioration from constant UV exposure, caused obvious openings in the membrane. Rain Man’s inspectors noticed these problems, as well as related failures in the expansion joints, and worked to come up with a viable solution.

The Repair Proposal

Together, Hughes and Easter proposed installing a spray-in-place polyurethane foam roof system over the existing system. The proposal covers the north end of the building (the 100,000-square-foot portion of the roof), where the majority of the controlled environment warehouse (CEW) is located. Hensley’s budget required that the southern portion of the building be repaired later; this second stage was tentatively set for August 2018.

A 1-inch thick layer of polyurethane spray foam was applied over the entire existing roof system. The foam was also used to form flashings at penetrations. Photos: Rain Man Roofing

The answer to the lap problems was to broom and blow the roof, which entailed cleaning the roof of debris and smoothing out the plies to ensure contact with adhesives. Lapolla Thermo-Prime Acrylic Roof Primer was to be applied to the roof, followed by a 1-inch layer of spray polyurethane foam (FOAM-LOK™ LPA 2800-4G) on top of the primer. Finally, a double-pass application of acrylic elastomeric Thermo-Flex 750 coating would finish the job.

Scheduled to start in April 2018, work was expected to take three weeks to complete and would require two foam rigs and eight full-time roofers with Rain Man’s David Caballero as foreman. Hensley would provide the roofers with a covered staging area (normally used as a patio for side-loaded delivery vehicles), where the crew could store equipment and roofing materials.

The staging area would allow Rain Man to shield its supplies and equipment from the high winds and cold weather. Because the job took place in April, when cold temperatures are common in Tucson, the spray foam would be stored under the patio cover. The colder spray foam gets, the longer it takes to warm it up so it can be used effectively.

The finished product was designed to take advantage of the insulating properties of the original roof, and the new “cool roof” monolithic system overlaying the old one would add R-value to the warehouse. The lightweight concrete separator would be retained so the spray foam wouldn’t fill the low spots in the corrugated metal roof deck, which would be a waste of materials.

Roof System Installation

Rain Man Roofing began the project with a pre-job inspection to discuss the application process of the new roof, go over safety and logistical concerns and keep the team at Hensley in the loop. Hughes prides himself on keeping his clients informed of each step in the roofing process.

Photos: Rain Man Roofing

After the details of the roof application were ironed out, the roofers set up their safety precautions. The Hensley building’s low-slope roof did not pose any unusual safety precautions, but Tucson regularly experiences strong winds that make roofing jobs more dangerous. Bright light also presented a danger to the roofers’ eyes, especially after the white acrylic coating was applied. The light reflected off the roof from the intense Arizona sun can be blinding. Hughes and Caballero made sure that their roofers took appropriate measures against the wind and the blinding light.

During the project, safety meetings were held every morning before work to discuss any danger areas that might present themselves that day. The crew also had to ensure each day that the surrounding area was protected from overspray. Sometimes this involved moving company vehicles away from the building.

Once they climbed up onto the roof, the roofers removed and properly disposed of 830 linear feet of expansion joint. After new expansion joints were mechanically fastened to the existing metal deck, the roof was blown and pressure washed free of dirt and debris. Polyurethane foam requires a completely clean surface to ensure a proper bond.

Thermo-Prime was applied to the prepped roof at a rate of one-quarter gallon per 100 square feet. Next, a 1-inch thick layer of polyurethane spray foam was applied over the entire existing roof system. The foam was also used to form all penetration flashings as needed.

Finally, the white acrylic protective coating was applied evenly to the roof in two passes. Each pass used 1.5 gallons per 100 square feet, adding up to three gallons total as described in the manufacturer’s specifications and 10-year limited warranty requirements.

When All’s Said and Done

After three weeks of hard work, high winds and bright sun, Rain Man completed Hensley’s new monolithic roof system. The new roof, designed to have zero seams and zero breaks between flashings and the roof system, will now stand up to the harsh desert climate and add a minimum of an R-6 insulation value to the controlled environment warehouse.

The Hensley Beverage Company is thrilled with its new roof and ready to contract Mark Hughes and Rain Man Roofing for more work in the future, starting with the southern part of the Tucson facility in August.

Hensley’s Anthony Keffer was also kind enough to provide beverages — non-alcoholic, of course — direct from the warehouse to the roofers working in the hot sun. And in the evenings, they were treated to some Bud Light to celebrate a job well done.

Coordination Is the Key to Re-Roofing Active Port Terminal

Owned by the Port of New Orleans, the Nashville Ave. Terminal Complex offers more than a million square feet of cargo space. When the structure’s original built-up roof reached the end of its service life, a standing seam metal roof was manufactured and installed by Ray Bros. Inc. on the vast majority of the building.

Construction projects on active jobsites can mean coordinating a lot of moving parts. Projects don’t get much more complicated than the recent roof replacement at the Nashville Ave. Terminal Complex, owned by the Port of New Orleans. The scope of work was multifaceted, the schedule was daunting, and everyone entering the facility had to have the proper security credentials. All of the work was performed next to the Mississippi River on top of an active wharf building, with cargo coming in and going out on trucks and forklifts as ships were loaded and unloaded. Materials housed inside the building were sensitive to moisture, dust and debris — and often had to be moved as work progressed.

Gino Ray Sr., president of Ray Bros. Inc., the roofing contractor on the project, likened it to a giant, three-dimensional puzzle. “It was almost like a Rubik’s Cube,” he says. “They had to move a section of material, and then when we finished a section, they slid the material over there so we could move on the next one. The whole time, the port was in operation. There was a lot of dancing involved.”

The Terminal

The Nashville Ave. Terminal Complex, operated by Ports America Louisiana Inc., offers more than 1 million square feet of storage space. Built in the 1960s, the structure was a rigid-frame, iron building with a ballasted tar and gravel roof over a heavy tongue-and-groove wooden deck. Decades of problems had seriously deteriorated the wooden deck, as well as the four-by-four wood nailers that were bolted to the rafters and purlins.

Key members of the team on the project included (from Left) N. Guy Williams of ECM Consultants, Kevin Haslauer of Glendale Enterprises, Gino Ray Sr. of Ray Bros. Inc., Craig Clark of Gulf Coast Service Group, and Curtis Shinogle of Gulf Coast Service Group.

The structure’s failing roof was replaced in three phases. During Phase 1, undertaken about a decade ago, a new built-up roof system was installed on one end of the building. When that section experienced performance issues, the owners looked for other options. Ray Bros. had the answer: an architectural metal roof.

Ray Bros. has been in business in New Orleans since 1996, when it was founded by Gino Ray Sr. The company has always focused primarily on metal roofing, and in the late ’90s it began roll forming and manufacturing its own panels and systems. “Today we manufacture everything we install,” Ray notes. “We’re kind of a hybrid — a manufacturer/contractor.”

The company’s metal panel system had been installed on several other port buildings, and the owners specified it for Phase 2 of the project, which covered a 230,000-square-foot section near the center of the building on either side of the firewall. Phase 2 was completed in 2014. Phase 3 encompassed 420,000 square feet to complete the sections on either side of Phase 2. Work began in August of 2016 and completed in May of 2017.

Ray Bros. manufactured and installed all of the metal roofing on the building — a total of 650,000 square feet — and served as both the prime contractor and the roofing contractor on the third phase of the project. Ray credits his dedicated team, the cooperation of all of the companies involved, and an innovative strategy for coping with the project’s many hurdles as the keys to a successful outcome.

Beefing Up the Structure

The standing seam metal roof system recommended by Ray Bros. was specified for its durability and low maintenance. The new system would give the port the long lifespan the owners desired, but it would necessitate some structural changes.

“Before we put the metal roof on, we had to beef up the existing trusses and reinforce the existing structure because it was such a light building now,” Ray notes. “There was an enormous amount of welding to the exiting trusses and existing purlins that had to be done before we could begin to put the roof on.”

The plan was to beef up the structure from the inside and install the new gutters. Then the old roof could then be torn off and the new metal roof installed. The roof installation would be completed in sections, with crews moving from one area to the next in sequence.

Gulf Coast Service Group served as the structural steel and demolition contractor. Crews on man lifts set up inside the building reinforced the existing steel structure. New angle irons were welded to the bottom of the purlins. The existing sprinkler system had to be reconfigured, as it was attached to the four-by-four wood nailers that had to be removed. Work on the sprinklers was performed in conjunction with S & S Sprinkler Company. “We didn’t have to dismantle the sprinkler system, just move it,” Ray explains. “New hangers were mounted to the steel. We had to put a hanger on, take a hanger off. That was part of the tango dance as well.”

After the welders completed their work, crews from RK Hydrovac vacuumed the ballast off the roof. Prior to the demolition work, approximately 4,100 linear feet of gutters were installed. Oversized gutters were manufactured from 16-gauge stainless steel in the Ray Bros. metal shop, and all of the joints were welded together. Gutter sections were raised into place with a lift and secured with stainless steel brackets and hangers. “That gutter weighed about 11 pounds per running foot, and we made it in 21-foot lengths,” Ray notes.

The Roof Installation

The demolition crews and installation crews then swung into action. After sections of the deck were removed, metal panels were roll-formed on the site and installed. “The demo people would tear out a bay — which is a 20-foot section — all the way up to the ridge,” Ray explains. “On one side of the roof, the panels were 180 feet long. So, they would tear out a 20-foot-by-180-foot section, and we would come in right after that and put a 20-foot section of 180-foot panels down.”

Panels were made from 22-gauge galvalume. Zimmerman Metals supplied roll forming machines to Ray Bros. Inc. so the company could manufacture its proprietary product. The RBI MT-240 panels were 18 inches wide and interlock using continuous clips. A batten cap was installed over the top and then mechanically seamed using a machine manufactured by D.I. Roof Seamers.

The roll-up bay doors along the sides of the building and at the gable ends of the warehouse qualified it as a partially enclosed structure, which necessitated strict engineering standards. “In order to meet engineering standards, we had to use continuous clips,” Ray notes.

Every third bay had a skylight system to light the interior. Skylights used on the project were manufactured by CPI Daylighting Systems and installed by Glendale Industries. Custom-made curbs and crickets were fashioned by Ray Bros.

When skylights could not be installed right away, the openings were covered with plywood and felt to eliminate safety hazards and keep the interior of the building dry. “When the Glendale Industries people would show up, we’d remove the plywood and they would put on their system,” Ray notes. “As the job progressed, we’d re-use the same plywood and temporary coverings as we went along. We’d just leapfrog the plywood from curb to curb.”

After the roof was completed, the last step was to replace the wall panels in the interior that were designed to trap the smoke in the event of a fire. The old corrugated smoke panels were wired to the steel, but that system would not comply with today’s standards, so Ray Bros. created a sub-framing system to attach new ones. “We had 500 squares of smoke panels to install beneath the roof system,” Ray states. “We put in some16-gauge furring channels and attached the panels with screws. We manufactured all of that in house.”

The demo crews, installation crews, and skylight crews kept moving in sequence under the direction of Jobsite Superintendent Robert Sinopoli, a 30-year industry veteran who has been with Ray Bros. ever since the company was founded. Sinopoli monitored everyone’s progress on the site and made sure everyone knew their assignments each day. “Everybody leapfrogged everybody else,” Ray notes. “Everyone had their own song and dance, and if one person got out of rhythm, it would domino back.”

Everyone involved on the project also needed to have a dance card, as security on the site was tight. Workers needed to have a background check and Transportation Worker Identification Credential (TWIC). Every vehicle had to have proper registration, insurance and inspection tags. The jobsite did not allow personal vehicles, and this posed a problem for Ray Bros., as the company routinely had 40 to 50 workers on site. “Everybody had to be on a company vehicle in a seat with a seat belt,” Ray notes. “I had to buy a used bus to transport workers in and out. We painted it, put our logo on it and made it look pretty. We just drove it 1.5 miles a day. At the end of the job, I sold the bus.”

Big Chunks

The project was wrapped up ahead of schedule, and it was the sequencing of work that was the key its success, according to Ray. “We didn’t want to tackle this project one bay at a time; we were looking at big chunks at a time,” he says. “We were able to develop a rhythm quicker that way. Instead of changing hats several times in the course of a day or a week, we put a hat on, let it stay on, got a big section done and moved on to the next. We didn’t want to change tools and change personnel. We wanted to look at it like a monolithic application.”

In the end, it all boiled down to pride — no one wanted to be the one to falter. “We self-perform a lot of our work, and we have existing relationships with all of the subcontractors we use,” Ray says. “I’m never going to let them down or leave them hanging, and I know they are going to do the same for me. That’s what made that job go — no one wanted to be the weak link. Everybody had a job to do and they did it. It worked out great.”

It was a true team effort. “This was like our Super Bowl, and we won,” Ray concludes. “I’m real proud of my company, our people, and all the people we worked with. I know that on our next job, I can count on them and they know they can count on me.”

New Facility Keeps Popular Brewery Hopping

Tree House Brewing opened its new 51,200-square-foot brewery in Charlton, Massachusetts in July of 2017. Photos: Sika Sarnafil

Standing in line for hours for one case of canned beer might seem foolish to some people, but to fans of Tree House Brewing — which was recently named one of the country’s Top 15 Craft Breweries by Forbes magazine — it is well worth it. Tree House Brewing began humbly enough in 2011 in a barn in Brimfield, Massachusetts. And yes, there was a tree house on the property.

Since then, the brewery has grown so much in popularity that it required a bigger facility.  So in July of 2017, Tree House opened a 51,200-square-foot brewery on 68 acres in Charlton, Massachusetts. On opening day, the new facility consistently had 1,000 customers waiting for hours to purchase Tree House’s ales, IPAs and stouts. Many of the patrons traveled from out of state and some arrived at 6 a.m., six hours before the doors opened.

It’s been said that the key to Tree House Brewing’s success is meticulous attention to details such as temperatures, additives and the water used in the brewing. It only made sense that the same attention to detail would be utilized when selecting a roofing system for the new facility.

Meeting the Bar

The roof that Tree House Brewing selected to cover its new brewery is Sika Roofing’s Sarnafil EnergySmart PVC membrane installed with the Sarnafil RhinoBond System. “We like Sarnafil because it is easy to use, easy to specify and an industry leader,” says Peter Webster, designer/project manager at Austin Design in Brattleboro, Vermont. “The light colored, reflective roof also offers energy savings, and our past experience with the Sarnafil roof shows it is a great product.”

The fact that the Sarnafil system is easy to install was an important factor, considering the time crunch of the project. “This was a ‘hurry up’ project — we weren’t done with the design when the steel structure went up,” Webster explains.

The Sarnafil RhinoBond System uses advanced induction welding technology to bond the membrane directly to specially coated plates used to secure the insulation to the deck, all without penetrating the roofing membrane.

In addition, the Sarnafil RhinoBond System can be used in temperatures as low as zero degrees Fahrenheit (-18°C), making it an ideal application method for winter projects.

“Much of the installation was during the winter,” states Robert Luukko, president of Kidd-Luukko Corporation in Worcester, Massachusetts, the roofing contractor on the project.

“Not only did Kidd-Luukko have to deal with cold temperatures, but the site is on top of a hill so there were high winds,” says Frank Quigley, president and owner of F.D. Quigley & Associates of Wilbraham, Massachusetts, the construction manager on the job. And of course, since it was winter they needed to make the building watertight as quickly as possible.

“Fortunately, Kidd-Luukko was able to seal the building before we were hit by some big snowstorms in February,” Webster says.

Other challenges included installing a 42-foot by 8-foot skylight and working around gables where the low roof wrapped around the corners. “Kidd-Luukko employees were very professional, well managed and well organized,” Quigley states. “I’d be happy to use them again.”

“Can-Do” Attitude

“Bob Luukko and his team had a ‘can-do’ attitude that really helped move the project along,” Webster comments. In fact, Kidd-Luukko was able to complete the installation ahead of the allotted eight-month time frame, Luukko notes, adding that teamwork was key. “We had weekly meetings with a great group of guys involved with the project where we would discuss how we were going to come in on time and on budget with this installation,” he says. Sika Roofing representatives also played a role in meeting the deadline. “We had multiple visits from the Sika technician, which really kept the project moving forward,” Luukko remarks.

Today, both the roof and the brewery are doing great. “We’ve had no problems with the roof at all,” Webster says. Luukko adds, “This project went so well that we are receiving a lot of interest in installing Sarnafil roofs on other projects.”

At the new facility, Tree House Brewing will be able to produce 40,000 barrels a year — compared to 12,000 barrels at their former facility in Monson, Massachusetts — and they plan to eventually expand the capacity to 180,000 barrels a year. That’s news that should make thirsty Tree House beer fans very, very happy.

Rooftop Decks Add Outdoor Living Space to Sacramento Town Homes

More and more, builders, architects and designers are looking to the rooftop as an area for usable living space — especially in urban areas, where lots are narrow. For a new town home development in Sacramento, the idea to add rooftop decks emerged late in the design process, but it’s proved so popular the builders are not only glad they made the change — they are considering making it a standard feature in future projects.

Designed by Ellis Architects and built by The Grupe Company, the neighborhood is known as 20 PQR. “The project fronts on 20th street in mid-town Sacramento and runs from P Street down to R Street,” notes Ron Rugani, vice president and purchasing manager for Grupe. “Q Street runs down the middle of the project, so that’s how we came up with the name 20 PQR.”

The 32 town homes are arranged in four groups of eight. The three-story residences have two different floor plans, one with 1,750 square feet and the other 1,850 square feet. “It’s an interesting concept,” Rugani says. “They are really considered single-family homes. They have their own lot, and they are detached from the next unit. There is a 6-inch space between the units, and they don’t share a common wall. However, the way we trim out that space, on the top and sides, you would view the eight units as one building, but they are actually eight individual single-family detached town homes.”

The narrow lots left no room for a yard, so that’s what inspired the idea to create usable outdoor space on the roof. “If you can imagine the urban setting — the fronts of these units are right on the city sidewalk. All of the units have two-car garages in the back and are accessible through a common alley. But there is no outdoor living space, and so that’s essentially what’s driving these roof decks,” Rugani says. “The backyard is where people are going to have outdoor living in a typical single-family home, and the rooftop deck is where they are going to have outdoor living in a town-home setting.”

The low-slope roofs were designed with internal drains and parapet walls. A GAF TPO roof system was specified. When the decision was made to add the rooftop living area, Ellis Architects recommended installing rubber roof deck tiles from sofSURFACES on top of the TPO roof. “The architect steered us in this direction because they liked the product,” notes Rugani. “After the roofer installs his regular TPO roof, it gets inspected to make sure there are no leaks before the roof deck tiles are installed. It’s a really unique product. It allows water to go through to the TPO roof for drainage. It has an excellent warranty, and so we have a long-term warranty for the entire roof system.”

Applying the Roof System

The TPO roof system was installed by PetersenDean Roofing and Solar, Fremont, California. “We are a roofing subcontractor for Grupe on several projects in the Northern California area,” says Mark Vogel, president of PetersenDean’s Builder Division. “We have built a great relationship with them over the years.”

There was approximately 900 square feet of roof area on each structure. PetersenDean crews mechanically attached the 60-mil GAF EverGuard TPO membrane over quarter-inch Georgia-Pacific DensDeck roof board and rigid insulation. “It is a flat roof with low slope conditions,” Vogel says. “This is absolutely a great system for this type of work.”

The parapet walls greatly simplified the safety plan, but safety is never taken for granted, according to Vogel. “We have 22 safety engineers nationwide, with 14 in California,” he says. “Safety is our biggest concern, and we invest to ensure we send everyone home at night. Our workers are considered our most valuable asset and we strive to maintain a world-class safety culture. Having a skilled and talented workforce that truly cares about safety drives everything that we do.”

Everything on the project went smoothly, notes Vogel. “It was not tough to coordinate the work with the other trades,” he says “It is what we do, and there is no one better. We are a full-service roofing contractor and solar power installer. We handle estimating, design, permitting, and installation for roofing and solar roofing systems for all our clients and this project is a great example of this.”

Installing the Roof Tiles

The deck area on each roof encompassed approximately 700 square feet. The interlocking duraSTRONG tiles are made from recycled rubber and are ideal for outdoor rooftops, walkways and patio projects, notes Chris Chartrand, director of marketing for sofSURFACES. “This space was ideal for our product as the rooftops are flat and have proper slope with a contained edge,” Chartrand says. “The design allows for efficient drainage of surface water.”

The low-slope roofs were covered with a TPO roof system manufactured by GAF, and the deck areas were topped with interlocking rubber paving tiles from sofSURFACES. Photo: sofSURFACES

The tiles were applied by a manufacturer-certified installer, Leonard’s Construction of Fontana, California. “Coordinating delivery and installation of our product within Grupe’s required timelines was a fairly easy task, as we were the last phase of the project,” notes Chartrand.

Paulo Carrillo, installation supervisor, typically installs the product in gyms and playground areas, but recently he’s found himself doing a lot of work on terraces and rooftops. After the roof system was completed on the homes at 20 PQR, a second sheet of TPO membrane was installed as a protective barrier. “We chalked our lines on that,” Carrillo notes. “We measure out the whole rooftop and chalk it off into a 2-foot-by-2-foot grid. Every other square is a keystone — those are the tiles that we put in first that hold everything in line.”

After the keystones are glued in place, the crews cut pieces to fit along the perimeter and then begin to add tiles in strategic lines. After those tiles cure, tiles are laid in opposite directions, both horizontally and diagonally. “We do it step by step,” Carrillo notes. “When we put the final squares in at the end, they are all interlocked together. After we do the final step, we glue each seam, so everything is 100 percent glued.”

The tiles all interlock, and compression allows for expansion and contraction. “Every tile is 24-1/8 inches, but they go into a 24-inch space,” Carrillo explains. “They are all compressed. With any perimeter cuts, we add another 1/8 of an inch to get our compression.”

Stacking the Deck

According to Rugani, Phase 1 and Phase 2 of the 20 PQR have been completed and are sold out, while Phase 3 and Phase 4 are currently under construction.

The interlocking duraSTRONG tiles are made from recycled rubber. They are designed for use on rooftops, walkways and patio projects, as well as gyms and playground areas. Photo: sofSURFACES

Originally the roof deck area was offered as an option, but it’s proved so desirable all of the units in the last phase are being built with decks. “It’s been an interesting dynamic,” says Rugani. “When we started, we weren’t sure how many people would want this option. For the first phase, we had to spec those, so, we said, let’s build six of the eight with the roof deck. It started to gain in popularity, and the price didn’t seem to be an issue, so in the last phase, we said, let’s build them all. It’s become very popular.”

Based on the success of the roof decks at 20 PQR, Grupe is exploring roof deck options for other projects in development. “We are building a mid-rise apartment complex just a few blocks away, and we said from the get-go in that project that we are going to have some type of roof deck for outdoor living space for the tenants,” Rugani says. “For that project we did develop a rooftop deck, and I believe that is going to be the M.O. moving forward in any project we do. Otherwise there might be no place for tenants to gather on site and have some outdoor living space. It makes perfect sense to go to the roof. So, yes, I see this as a trend, especially in urban settings.”

In the 20 PQR project, the homes were not originally designed with roof decks, and the decision made to add them later meant a lot of extra time and work for engineers and architects. “A lot of people might walk away from that and say it is too much work,” Rugani says. “We said, this is something we need to do, and it’s going to benefit the people who buy it. We were happy in the end that we spent the time and effort to do it.”

Zinc Roof and Wall Panels Add Sense of Movement to Chicago Boathouse Project

The new Eleanor Boathouse at Park 571 in Chicago’s Bridgeport neighborhood creates the opportunity for greater community recreation and environmental stewardship of the Chicago River. Designed by Studio Gang Architects, the 19,000 square-foot facility is the last of four new boathouses and river launches created by the Chicago Park District to reclaim the Chicago River as a major system of parks and water-based recreation.

The unique form of the two-building boathouse reflects the movement of rowing, according to Studio Gang’s founding principal Jeanne Gang. The design, incorporating alternating roof trusses, was influenced by studying the rhythm and motion of rowing. “The Chicago River boathouses are part of a new environmentally friendly vision for the city’s river,” says Gang. “By making the riverfront a destination for recreation, anchored by dynamic sustainable architecture, we hope to catalyze long-term stewardship and support of the river’s remediation.”

The striking design incorporates zinc panels from Rheinzink in both roof and facade applications. Approximately 23,000 square feet of Rheinzink prePATINA blue-grey Double Lock Standing Seam Panels cover the roof of both buildings. An additional 10,000 square feet of the company’s Flat Lock Tiles clad the facade in a diagonal installation.

Zinc panels were also used to clad one of the other four boathouses completed earlier and also designed by Studio Gang Architects. The WMS Boathouse at Clark Park on the northwest side of the city was the second of the new boathouses to open and utilized 7,000 square feet of vertically-oriented Rheinzink Flat-Lock Tiles for the facade.

The panels for both projects were fabricated by Rheinzink systems partner Sheet Metal Supply Ltd. (SMS), Mundelein, Illinois. Installation of the panels on the Eleanor Boathouse was done by Bennett & Brosseau, Inc., Romeoville, Illinois.

The panels chosen for the project were the result of an exhaustive search that ruled out more expensive alternatives. “Rheinzink reduced the cost and provided the great diagonal look that Studio Gang wanted,” says Bennett & Brosseau project manager Ryan Broom. “It’s a ‘full zinc’ job with both the facade and the roof and really turned out nice.”

SMS vice president Ben Kweton credits Broom with providing the invitation to become involved in the project. “When Bennett & Brosseau approached us with the value engineering opportunity, we jumped at the chance to provide pricing and to remind the design team of the success of Rheinzink on the earlier boathouse project,” Kweton says.

The design team also opted for a slightly hybrid version of traditional flat lock panels. “The tiles we fabricated had a slight offset at the top to bring the panel overlaps more into plane and to create a slight reveal,” Kweton says.

Broom finds working with zinc rewarding, noting, “It provides a great quality look and allows more architectural detailing than can be done with many other metals.”

New Roof Provides Security at Senior Living Complex

Photo: Johns Mansville

The Preserve At Palm-Aire is a landmark senior living community in Pompano Beach situated on 13 acres of lush, beautiful grounds in South Florida. Offering both independent living and assisted living programs, the health care facility’s primary focus is on preserving residents’ quality of life in every way possible.

The independent senior lifestyle at The Preserve At Palm-Aire is all about maintenance-free living, and that philosophy influenced the choice of a new roofing system for the facility.

The re-roofing of The Preserve At Palm-Aire was complicated by Mansard-style roofs and 5-foot to 6-foot high parapet walls that greatly restricted access to the existing roofing system, which was installed on a lightweight structural concrete deck. The use of trash chutes was impossible, so a large crane and dumpster were used to remove the roofing debris.

“What concerned us most was using such a large crane around an immaculately landscaped property fully occupied by tenants especially sensitive to excess noise and vibration,” says Geo Madruga, commercial project coordinator for A-1 Property Services Inc., the Miami-based roofing contractor on the project. Another important concern was that the low-slope roof had numerous penetrations, including those for 30 large HVAC units and various pipes and stack vents.

Finding a Solution

A-1 Property Services Inc. competed with several other contractors on an open spec bid. With the help of JM Sales Representative Lewis Buckner, A-1 advised the property owner that a 60-mil fleece-backed PVC membrane with DuPont Elvaloy KEE would provide the longevity, energy efficiency and chemical resistance required for the project. “We really pushed the PVC fleece backed as the superior roofing system and a unique solution for this building,” says Madruga. “We also felt more comfortable with JM’s PVC membrane due to our long track record with the product.”

Adhered directly to the concrete deck with a water-based adhesive, the fleece-backed PVC exceeded Broward County’s 175-mph wind resistance requirement. The PVC membrane’s high reflectivity also earned an energy efficiency rebate from Florida Power & Light Company. The product was also easy to install, depite the numerous penetrations, notes Madruga. “While there were definitely many unique penetrations, our 10-man crew had no problems with the heat-weldable PVC membrane,” he says.

Madruga’s concerns — and his company’s name — both reflect A-1’s desire to create long-term relationships with clients that include expert maintenance services. “We met the expectations of the owner’s roof consultant, but with offices in Washington D.C., the client placed a tremendous amount of trust in the roofing manufacturer and contractor,” adds Madruga. “We are specialists, and we don’t just walk away from any roofs that we install.”
