The project included 34 dormers that feature double-lock standing-seam copper and fascia metal.

ROOF MATERIALS

Wagner Roofing was awarded the complete replacement of all roof systems. These included an upper double-lock standing-seam copper roof system, a bullnose copper cornice transition, slate mansard, 34 dormers with double-lock standing-seam copper and fascia metal, eight copper hip metal caps and a continuous built-in gutter with decorative copper fascia. Each of the dormers also had a copper window well.

The upper standing-seam roof was removed and replaced with 24-inch-wide, 20-ounce copper coil rollformed into 1-inch-high by 21-inch-wide continuous standing-seam panels that matched the original profile. The eave bullnose, which also served as the mansard flashing, was removed and returned to Wagner Roofing’s shop where it was replicated to match the exact size and profile.

The 34 dormer roofs were replaced with 20-inch-wide, 20-ounce copper coil formed into 1-inch-high by 17-inch- wide continuous standing-seam panels. The decorative ornate fascia of the dormers was carefully removed and Wagner’s skilled craftsmen used it as a template to develop the new two-piece copper cornice to which the roof panels locked. The cheeks and face of the dormers were also re-clad with custom-fabricated 20-ounce copper.

The oversized built-in-gutter at the base of the slate mansard was removed and replaced with a new 20-ounce copper liner custom-formed and soldered onsite. The replacement included a specialty “bull-nosed” drip edge at the base of the slate and an ornate, custom-formed fascia on the exterior of the built-in gutter. The decorative copper fascia included 85 “hubcaps”, 152 “half wheels” and 14 decorative pressed-copper miters. The original hubcap and half-wheel ornaments were broken down and patterns were replicated. Each ornamental piece was hand assembled from a pattern of 14 individual pieces of 20-ounce copper before being installed at their precise original location on the new fascia. The miters were made by six different molds, taken from the original worn pieces, to stamp the design into 20-ounce sheet copper.

In all, more than 43,000 pounds of 20-ounce copper was used on the project.

ROOF REPORT

Maury Hall was built in 1907 and was designed by Ernest Flagg. Flagg designed many of the buildings at the U.S. Naval Academy, including the Chapel, Bancroft Hall, Mahan Hall, the superintendent’s residence and Sampson Hall. His career was largely influenced by his studies at École des Beaux-Arts, Paris. Examples of Flagg’s Beaux-Arts influence can be found in the decorative copper adorning the built-in gutter on building designs.

Maury Hall currently houses the departments of Weapons and Systems Engineering and Electrical Engineering. The building sits in a courtyard connected to Mahan Hall and across from its design twin, Sampson Hall.

MiaSole and General Membrane Announce Partnership Agreement

General Membrane SpA, the premiere Italian provider of bitumen, synthetic and metal roof waterproofing membranes, and MiaSolé have entered a strategic partnership agreement. General Membrane will integrate the MiaSolé flexible thin-film CIGS (Copper Indium Gallium Selenide) FLEX module—the thin-film lightweight flexible module with an aperture efficiency rating of up to 17%—into their new General Solar PV FLEX, an innovative solution for the waterproofing sector. General Solar PV Flex is composed of MiaSolè flexible modules adhered to a General Membrane bituminous or synthetic waterproofing layer. General Solar PV FLEX becomes an integral part of the roof and offers the double benefit of waterproofing and generation of electricity, and can be used on new and existing flat or sloping roofs as well as roofs with variable geometry, such as curves.

The MiaSolé FLEX module has several features that make it ideal for General Membrane’s waterproof membranes. In addition to its high efficiency rating, the low weight of the module (<2.9kg/m2) allows installation on roofs that cannot support the weight of traditional glass solar panels. The peel-and-stick application allows the FLEX module to be fully integrated into the membrane, conforming to curved surfaces and offering superior resistance to wind. “We are proud of this partnership agreement between our company and MiaSolé that is in accordance with the mission of General Membrane SpA. The role of the roof is changing and modern waterproofing systems must meet, through innovation, the new functions of the roof, ensuring durability. The partnership with MiaSolé and its innovative Flex modules allows us to continue in our proposal of BIPV systems and our commitment towards the environmental solutions”, said Maurizio Codognotto, president and CEO of General Membrane SpA. “The MiaSolé module helps General Membrane create solutions for today’s challenges integrating solar power generation into buildings,” says Anil Vijayendran, vice president of Product Sales and Marketing at MiaSolé. “We are pleased with this partnership with General Membrane, a company that has proven its commitment towards the environment by installing more than 45MW of solar since 2007. Working with General Membrane highlights our commitment to expand the solar energy ecosystem with this integrated General Solar PV FLEX waterproofing membrane”. “This partnership agreement with General Membrane is an example on how the MiaSolé flex module can be used to create unique solutions preserving the integrity of the roof and rewards the choice of Hanergy to invest in flexible CIGS technologies. We are proud of this partnership with General Membrane, a company that already proved its commitment towards the environment installing, since 2007, more than 45MW of solar”, said Li Ming, CEO of Hanergy Europe, MiaSolé’s sales partner in Europe.

Roof Hugger Celebrates 25th Anniversary

In 1991, two developer/contactors and longtime friends, Red McConnohie and Dale Nelson, began a part-time business to manufacture and distribute structurally sound sub-purlins for installing a new metal roof directly over an existing metal roof. The idea came about because McConnohie owned a lease building that needed its roof to be replaced. After a few design sketches using a factory-notch concept with some ingenuity, the original Hugger sub-purlin came alive. McConnohie got his building reroofed and proposed to Nelson that they start a business together selling this innovative new product. So, they set off on a journey, which has lasted 25 years, and now has covered more than 70 million square feet of existing roofs nationally and abroad. The company is the brand Roof Hugger Inc.

The trek was not always that easy because the product is designed to fit over and around the major ribs of the existing panels. Have you ever thought about how many different metal roof profiles are out there? Hundreds, if not thousands. You have ribbed panels in a multitude of spacing and heights from 6 to 13 inches, there are corrugated panels with corrugations spaced from 2.25 to 4 inches, and of course, there are standing seams. These also widely varied because of the vertical and trapezoidal seam configurations, rib-to-rib spacing and heights and with or without standoff clips. Today, Roof Hugger has built a library full of manufacturer literature, both from the old days and the more recent. They refer to this library countless times during a given year but even to this day, they are given a previously unknown panel from a contractor or building owner needing to reroof an existing metal building.

Not only do the profiles and variations of existing metal roofs make this niche roof replacement market challenging at times, but because of the new stringent code requirements, you have panel testing to contend with, as well. Every manufacturer today, producing metal roofing, has and will continue to have their systems tested for performance. The most utilized test standard is known in metal construction as the “Standard Test Method for Structural Performance of Sheet Metal Roof and Siding Systems by Uniform Static Air Pressure Difference” or ASTM E-1592. Without it, it is extremely difficult to engineer roofing products to meet specified building code requirements for given wind speeds. It is not widely understood but each metal roof’s testing can and does vary from its counterparts although they frequently can look almost identical. This is due to seam design, clip design, metal thickness, design specifications and manufacturing limitations. Because of this, Roof Hugger began testing in 1996 and now has numerous metal roofs that have been tested over their sub-purlin systems. They have an (FM) Factory Mutual approval, as well as several (FL#) Florida Product Approved assemblies.

As Roof Hugger celebrates its 25th year, the Hugger team located outside Tampa, Fla., is excited to carry the “Hugger” brands on into the future. McConnohie passed in 2013 at the age of 87, and Roof Hugger is a big part of Red’s legacy, but Dale and Jan Nelson, now owners of Roof Hugger, continue to work relentlessly to make the Hugger stable of products better than any other metal-over-metal retrofit roof system available. Jan Nelson recently commented that “they are so fortunate to have met and grown to know the fabulous people in the metal construction industry via trade shows and organizational meetings. She went on to say, “We have gained an extended family that is surely the best gift of this journey and it puts a smile on my face daily.” Dale Nelson said, “I can’t believe it’s been 25 years. It’s been one heck of an enjoyable ride.” Dale Nelson was recently elected chairman of the Metal Construction Association (MCA), which he is no stranger to this kind of work. He has committed much of his life to volunteer work in both his private life, as well as in business activities.

Roof Hugger now has four production locations in Florida, Indiana, Texas and Washington. Three of their sub-purlin profiles can ship within two to three days and others are made-to-order to ship within 10 to 15 days. Roof Hugger is specified by numerous levels of local, state and federal government agencies, especially the U.S. Military. A recent look at their shipments, found that more than 3 million square feet have been installed at more than 70 domestic military facilities. They provide quotes in hours and a live voice always answers the phone. Prior to Red’s passing, if you were lucky he would answer the phone with a loud “ROOF HUGGER – McCONNOHIE”, and when you call today you will still get an equally enthusiastic greeting from the Roof Hugger crew of Jan, Bill, DJ or Dale.

Converting Existing Carports to Solar Carports with Flexible PV Modules

Rooftop solar has become commonplace on commercial buildings and homes. Although a residential home often has sufficient rooftop area to power the home 100 percent with solar, this is not always true with multi-story commercial buildings, apartments and condominiums. The properties often do not have the necessary roof space to offset their energy needs with solar. This situation can also apply to low-rise buildings with high electrical usage, such as factories, big-box stores and warehouses.

The Miasole FLEX Series PV Modules

The Miasole FLEX Series PV Modules

Carports have become a standard feature on many commercial and multifamily properties. Even buildings without carports have parking lots with space for them. Carports provide users the benefit of shading cars and protecting cars and people from rain and snow. Carports keep cars cool, reducing the power required to air condition them when they’re started and reducing sun damage to the car finish. From an environmental standpoint, carports help migrate the heat island effect in which large concrete and asphalt parking lots absorb heat during the day and release the heat at night. This additional heat can drastically change local weather patterns, especially in metropolitan areas.

In recent years, building owners have been installing new carports with solar PV modules. These solar carports have all the benefits of traditional carports with the added advantage of producing clean renewable solar energy while reducing the need to add rooftop solar to buildings.

In many places, existing carports were designed and built with minimal steel support structures and the metal roof and deck panels are already spanning the maximum distance between supports to keep costs down. Most were built to meet the minimum local wind and live-load code requirements. With the cost of solar installations falling, utility energy costs rising and increased interest in improving the environment while reducing a building’s carbon footprint, building owners are interested in retrofitting their existing carports with solar modules. Unfortunately, many of these existing carport structures cannot support the additional 4- to 6-pounds-per-square-foot weight of standard crystalline PV modules and associated racking and rails. The only solution available to the owner is to structurally upgrade the carport or tear it down and replace it with a carport designed for the extra weight of solar. Even if the existing carport structure can support the weight, retrofitting the carport with solar can be technically challenging and expensive.

MiaSolé has developed two solar application solutions to solve the live-load limitations of many existing carports. MiaSolé manufactures a flexible lightweight high-efficiency (16 percent plus) CIGS-based flexible PV module weighing less than 9 ounces per square foot in two format sizes: the narrow-format FLEX-N series designed for traditional architectural standing-seam metal roof panels and the wide-format FLEX-W series. Both can be applied to the carport roof with a simple peel-n-stick adhesive.

Standing-seam Panel

Two roofers can easily apply the FLEX-N series to the existing carport metal panels:

  • Power wash the roof.
  • Wipe down the areas where the FLEX-N modules will be applied with rubbing alcohol.
  • On the standing-seam metal panel (16- to 18-inches wide) lay down the module.
  • One roofer lifts up the module at the j-box end, removes the release film from the adhesive and sets the module down.
  • The second roofer at the other end lifts up and supports the module.
  • The first roofer continues to remove the release film and lays down the module, rubbing the module with his hand to ensure full contact.
  • Once the module is fully adhered, both roofers use a silicone roller to bond the module to the metal pan surface.

Trapezoidal Rib Panel

Although architectural standing-seam panels are frequently used on carports, the 7.2 trapezoidal rib panel is the metal roof industry’s most commonly used corrugated roof panel for carports. Nearly every major metal roof and steel building manufacturer offers a 7.2 rib panel type profile.

The 7.2 corrugated rib panel is economical, strong and aesthetically pleasing while offering excellent spanning and cantilever capabilities, making it an excellent choice for carports and walkway canopies. The 7.2 rib panel with its long-spanning performance helps lower costs by reducing the number of purlins and structural steel needed. The ability to use long metal panels and fastening with exposed fasteners on slopes as low as 1:12 greatly reduces labor costs.

Installing the Miasole FLEX W on a 7.2 Metal panel

Installing the Miasole FLEX-W on a 7.2 metal panel.

Working with several major metal roof manufacturers such as McElroy Metal and one of the solar carport leading builders, Baja Construction, MiaSolé modified the adhesive patterns on the MiaSolé FLEX-W, the large-format PV module originally designed for low-slope single-ply roofs. The new adhesive pattern makes it simple to bond the MiaSolé Flex-W module directly across the standard 7.2 corrugated rib profile. By eliminating the need for racks and rails, the powerful 360-watt FLEX-W PV module can be rapidly installed by just two roofers over any existing carport or walkway. With a low-slope roof canopy, solar orientation—the direction the carport is facing—is less critical.

Two roofers can easier apply the FLEX-W series to the existing carport metal panels:

  • The existing carport is power washed to remove any dirt and debris from the metal roof surface.
  • Any loose panel fasteners are tightened and missing fasteners replaced.
  • The areas where the FLEX modules are to be installed are cleaned with rubbing alcohol.
  • The FLEX modules are laid down across the corrugated ribs, and the adhesive strips are aligned with the ribs.
  • On one end, the roofer lifts up the module, peels back the adhesive release film, lays the module back down on the 7.2 panel ribs and presses down to bond the module to the ribs.
  • The second roofer on the other end repeats the same process.
  • Both roofers finish bonding the module by rolling the adhesive areas with a silicone roller to ensure complete adhesion to the metal panel.

MiaSolé FLEX series PV modules make it possible to economically convert existing carports with live-load limitations into new solar carports without having to make any major structural modifications. Even on new solar carports, the MiaSolé FLEX series modules can reduce labor and construction cost by reducing the need for heavy steel support structures and allowing longer metal panels with fewer support purlins.

The peel-and-stick adhesive system reduces labor costs while speeding up installation time. Unlike conventional rigid crystalline panels, the flexible MiaSolé FLEX modules work over curved roof structures for solar carports, solar walkways and solar awnings.

MiaSolé and Upland Corp. Enter into Sales Agreement to Sell Thin-film Lightweight Solar Modules

Upland Corp., a manufacturers’ representative firm that provides building material solutions to the commercial construction industries, and MiaSolé have entered into a sales agreement. Upland Corp. will sell MiaSolé FLEX modules in New Mexico and El Paso, Texas, territories. Since 1984, Upland Corp. has helped architects, building owners and contractors by providing quality building solutions to these valued construction partners.

Upland Corp. will engage in the sales and marketing of MiaSolé FLEX modules, efficient thin-film lightweight flexible modules that offer an efficiency rating of more than 16 percent. MiaSolé FLEX modules bond directly to the roof surface with a simple peel-and-stick adhesive. The low-profile FLEX module provides wind resistance and a seismic advantage providing huge benefits over traditional rack-and-panel solar systems.

The FLEX-02 Series module is available in two formats. The FLEX-02W module is 39.3 by 102.3 inches and is rated at 360 watts, and designed for low-slope commercial single-ply roof systems. The FLEX-02N module is 14.6 by 102.3 inches and is rated at 120 watts, and designed specifically for standing-seam metal roofs. The FLEX-02 Series module is IEC 61646 and IEC 61730 and UL 1703 certified.

The FLEX-02 module provides Upland Corp. customers other significant benefits. The low weight of the module (less than 0.7 pounds per square foot) allows installation on roofs that cannot support the weight of traditional glass solar panels. Because the FLEX-02 panels adhere directly to the roof surface, there are no penetrations, eliminating the worry of leakage and damage to valuable contents within the building. The FLEX-02 also is aesthetically pleasing, blending into metal and TPO roofs and preserving the original look of the roof.
