Vent Pipe Flashing Is Durable and Easy to Install

Quarrix offers the Pipe BootQuarrix offers the Pipe Boot, a durable vent pipe flashing that is compatible with PVC and other vent pipe materials. According to the company, the product offers roofing contractors a durable yet easy-to-install way to elegantly camouflage, cover and protect plumbing vent pipes while also withstanding freezing temperatures and rodents.

Pipe Boot is made of all-steel construction and engineered to withstand frigid temperatures and frost damage via a patented design that allows air space to circulate properly, while still resisting freezing. According to the manufacturer, the product has passed vigorous 110-mph, wind-driven rain testing. Additionally, installation is quite easy as Pipe Boot simply slides over the existing venting pipe, nails into place, and then the top is twisted to form a weather-tight seal. No specialty tools are needed.

The telescoping sleeve allows for varying pipe heights, pipe widths and roof pitches – and comes in four color options. It is paintable to coordinate with any roof color so vent pipes are cleverly camouflaged. Pipe Boot base sizes are available in both standard and high-pitch sizes (3/12 – 14/12) for a custom fit.

Self-Adhesive Roof Flashing Requires No Fasteners

Kwik FlashAtlas Bolt & Screw offers KwikFlash, a weatherproofing flashing which consists of aluminum stretch netting cast in environmentally friendly lead-free polymer rubber, which allows it to take a form set while remaining flexible, malleable and stretchable. A fully self-adhesive butyl layer underneath the rubber polymer is protected and backed by a release sheet removed during installation. Applications include difficult-to-flash areas such as skylights, square and round ducts, parapet walls, and in areas where traditional lead flashings are used. The product is compatible with most materials and can be successfully flashed between brick, fibre cement, galvanized steel, aluminum, stainless steel and concrete. According to the manufacturer, it is lightweight, easy to trim and no fasteners are required for significant labor savings.

FlashCo Acquires All Fab, LLC, Creator of the Easy Flapper

FlashCo has announced the acquisition of All Fab, maker of the patent pending Easy Flapper and a variety of TPO and PVC pipe and vent flashings. FlashCo is working with all of All Fab’s customers in their transition to FlashCo.

“We are excited to add All Fab products to our Northwest and nationwide operations,” says FlashCo President, Greg Morrow. “We have known Roger and Melissa Allestad for many years and we have respect for their designs and ability to develop parts.”

All Fab began operations in 2011, starting in a basement shop and growing to over 15 products including cones, breather vents, scuppers and corners. In 2015, All Fab product designer Roger Allestad developed the Easy Flapper to solve a HVAC issue on flat roofs. The Easy Flapper is an exhaust vent for commercial and residential roofs that prevents backdrafts and similar issues for dryers, bathrooms and kitchen hoods. The Easy Flapper offers installation and maintenance ease, and allows simple application designs. In addition, the Easy Flapper has patents pending.

“Melissa and I are excited to have this opportunity with FlashCo,” says Mr. Allestad. “I will
be returning full-time to Loberg Roofing and it gives me the chance to do what I enjoy, developing new products. It has been a blast building a local accessories company. FlashCo has acquired All Fab LLC, but FlashCo has the national reach to develop and grow the market, especially for the Easy Flapper. FlashCo is the right company to take it forward.”

Melissa Allestad has been a driver in developing a loyal customer base for All Fab in the Northwest. Ms. Allestad will be working closely with FlashCo Regional Sales Manager, Rick Morrow and his team to help customers transition to FlashCo. Over the next several weeks FlashCo and all Fab will be visiting customers together.

“It’s a natural fit,” says Mr. Morrow. “Both companies are dedicated to saving the contractor time and All Fab, just like FlashCo, has focused on customer satisfaction. We are
confident that All Fab’s customers will appreciate FlashCo’s service level and capabilities with our Washington plant, and the ability to deliver most orders is one to three days.”

“For us it’s a little bittersweet,” says Mr Allestad. “We have a hardworking team and we enjoyed growing the company, but the opportunity with Loberg is really too good to pass up. We are fortunate to be able to transition All Fab to FlashCo who can take the products to the next level. Plus, we will continue to consult with FlashCo on product development.”

The full transition of All Fab customers to FlashCo will be completed by the end of May.

Flashless Metal Edge Protects the Roof Perimeter

The flashless metal edge system eliminates the need for flashing plies that would ordinarily be installed at the roof’s edge.

The flashless metal edge system eliminates the need for flashing plies that would ordinarily be installed at the roof’s edge.

Garland’s flashless metal edge system eliminates the need for flashing plies that would ordinarily be installed at the roof’s edge, saving time during installation and costs on labor and material. R-Mer Force has re-engineered the way flashing is installed without compromising strength or longevity.
 
A roof’s perimeter is vulnerable to wind damage and moisture intrusion, requiring special details and flashing procedures to protect the building. R-Mer Force is anchored to exterior walls with aluminum anchors, which means there are no penetrations on the roof surface. Fascia cover pieces snap onto installed anchors, completing the installation and blocking out the elements to protect your building. 
 
Thermoplastic elastomer compression seals also contribute to the finish of R-Mer Force. Because the seals keep surface tension balanced, the oil canning effect that plagues other metal edge systems doesn’t affect the level edge surface of R-Mer Force. To complete the finish, customized splice plates make the transition between edge pieces uniform for a finished look. The system is available in a variety of colors to fit any aesthetic goals. 
 
These innovations don’t compromise on the strength and longevity expected from Garland’s metal systems. R-Mer Force meets building code ANSI/SPRI ES-1 requirements for structural integrity and wind resistance, ensuring security. The extruded aluminum anchor was designed and tested to withstand severe wind speeds, keeping the fascia secured. The fascia is available in steel and aluminum options.

Avoid Problems with Skylights through Proper Installation

As trendy as they are for green building and demonstrably beneficial for energy savings
through daylighting, skylights are sometimes viewed with a certain trepidation by roofing
contractors. After all, skylights are essentially holes in the roof with the potential to compromise roofing workers’ handiwork by providing unintended leakage paths.

Proper installation is essential to realizing designed-in leak-free performance and can vary by type of roofing involved and the type of skylight. It is recommended to always refer to and use the skylight manufacturer’s instructions that are specific to the roof system being installed. Of course, applicable code requirements supersede any instructions to the contrary.

AAMA 1607-14, “Installation Guidelines for Unit Skylights”, which is an industry consensus guideline published by the Schaumburg, Ill.-based American Architectural Manufacturers Association, intended for use when manufacturer instructions are absent or incomplete, provides basic step- by-step installation instructions for 19 different ways to integrate various roofing materials, underlayment, flashing and skylight-mounting configurations to preserve the drainage plane. This must be the overriding intent of any installation protocols.

Note that some roofing contractors warrant their work against leakage, and skylight installation should not compromise or void such warranties. When in doubt, independent installers should confer with the roofing contractor.

INSTALLATION SUPPLIES

Proper installation begins with selection and use of the proper supplies—notably sealants, fasteners and flashing.

SEALANT SELECTION
If sealants are recommended by the manufacturer, follow the manufacturer’s specifications. When the manufacturer is silent about the use of sealants and the installation guidelines dictate their use, the following recommendations should be observed:

  • Compatibility—The sealant must not adversely react with or weaken the material it contacts.
  • Adhesion—The sealant must have good long-term adhesion. Surface preparation, cleaning procedures and, in some cases, primers are recommended by the sealant manufacturer.
  • Service Temperature—If the installation location involves elevated ambient temperatures, the sealant should exhibit corresponding service temperature performance.
  • Durability—The sealant must be capable of maintaining the required flexibility and integrity over time.
  • Application—Proper bead size and other application details should be followed to ensure a well-performing joint. Improper use of sealants can dam water pathways, so an important rule of thumb is not to block any weep holes that may be in the skylight system.

Typically, sealant or roofing cement is applied around the perimeter of the rough opening (deck mount) or the flange of self-flashing units or the top edge of a mounting frame. However, some skylights are designed with integral flashing flanges to be installed without the need for sealants.

It is also possible to utilize rolled roofing membranes as a substitute for sealants or plastic roofing cement.

Roof Materials

The Catholic Archdiocese of Birmingham required the cathedral’s new roof system be a historically accurate reproduction of the original in materials, design and craftsmanship. The cathedral’s intricate slate tile patterns incorporated three slate colors and square and deep bevel cut tiles. Six large slate crosses and multiple accent patterns, barely visible on the faded original roof, required exacting measurements prior to tear-off and a high level of precision to recreate and maintain over such a large field and on octagonal steeples.

Because of metal thinning brought on by their advanced age, every copper architectural and functional feature in the existing roof system had to be carefully removed and shipped to Midland Engineering’s South Bend facility to be historically replicated in its metal shop. This included seven ornate crosses (up to 17-feet tall), finials, turret caps and more. There were more than four dozen components, for which no original prints existed, as well as over 500 feet each of custom copper cornices and radius gutters with matching straps. More than 20,000 square feet of 16- and 20-ounce copper was utilized for fabrication of architectural elements and flashing.

Midland Engineering was asked to make improvements to the original roof system to improve attic ventilation while maintaining the Gothic Revival period look. To accomplish this, the crew integrated bronze screen (invisible from the ground) into the original copper cornice and eave design to provide improved cold air intake while new louvered copper dormers replaced the original painted roof ventilator.

An updated lightning protection system was incorporated into the new roof design, hidden within many of the new copper crosses and other architectural elements. The system was fabricated in Midland Engineering’s shop to maintain the Gothic Revival look.

The metal shop also clad 10 previously painted windows and mullions in copper, effectively eliminating frequent and costly maintenance. These windows, reachable only by crane at considerable expense, formerly required painting and other maintenance every five to seven years.

About 6,500 square feet of lead-coated copper, which patinas to a limestone color, was utilized to cap all limestone exposed to weather, reducing ongoing maintenance of limestone joints.

Extensive termite damage to structural framing required repair prior to installation of the new roofing system. Upon removal of the original slate roof and completion of the structural repairs, the new roof was dried-in and installation of the new slate roof began. The historically accurate replacements of the original copper architectural features were installed according to schedule.

Roof Report

The Cathedral of St. Paul is the centerpiece of the Roman Catholic Diocese of Birmingham. Completed in 1893 at a cost of $90,000, the cathedral is widely considered to be a handsome example of the American Neo-Gothic variant of the Gothic Revival style. The cathedral measures 96-feet wide by 140-feet long and encompasses more than 60,000 square feet. It features twin octagonal steeples, rising 183-feet high.

Work schedules on this project were a challenge. The contract required parishioner and clergy access to the church must be maintained 24 hours a day, seven days a week, throughout the eight-month duration of the project. Further, because of the noise inherent in roof construction, work schedules had to be planned around regular church services and events and rescheduled several times a month for funerals and other unscheduled events.

“We could not have been more pleased with the work accomplished by the team from Midland Engineering,” says Very Rev. Kevin M. Bazzel, V.G., J.C.L., rector of the Cathedral of St. Paul. “It is a marvel to us to be able to see the church in its original glory, and all of this thanks to Midland!”

The National Roofing Contractors Association, Rosemont, Ill., awarded Midland Engineering the prestigious Gold Circle Award in 2016. Midland was recognized in the Outstanding Workmanship—Steep-slope Category.
