ARMA Releases Roofing Design Guide in Digital Form

The Asphalt Roofing Manufacturers Association (ARMA) has converted its Modified Bitumen Design Guide for Building Owners into an eBook, making it easier for roofing professionals to view it on their smartphones or tablets.

The Modified Bitumen Design Guide, which ARMA recently updated to reflect current roofing standards and building codes, serves as a general instructional aid for the installation of modified bitumen roofing systems. The guide addresses these roofing systems and their associated components, construction techniques and innovative uses.

It also provides options for overburdens, such as solar, garden and recreational installations, that push the roofing system and the membrane beyond their primary function of providing water resistance.

“Today more than ever, roofing professionals are being called to the jobsite for their expertise and knowledge regarding low slope roofing systems,” said Reed Hitchcock, executive vice president of ARMA. “By making the Modified Bitumen Design Guide available as an eBook, ARMA is providing them the information they need in a form that is easy and convenient to access on the go.”

The Modified Bitumen Design Guide is available for $24.99 as a print-on-demand copy or $19.99 as an eBook from ARMA’s Bookstore, as well as from prominent digital platforms such as Amazon’s Kindle Store, Barnes and Nobles’ Nook, Apple’s iBookstore and more. To purchase the Modified Bitumen Design Guide, visit the ARMA bookstore.

Miami-Dade County and ARMA Team Up to Update High-Wind Codes

ARMA awarded the Miami-Dade Regulatory and Economic Resources Department the 2017 ARMA Public Partnership Award.

ARMA awarded the Miami-Dade Regulatory and Economic Resources Department the 2017 ARMA Public Partnership Award. Aaron R. Phillips, Corporate Director of Technical Services at TAMKO Building Products and chair of the ARMA Codes Steering Group, presented the award to Michael Goolsby and Miami-Dade team members who worked on the project. Pictured at the ceremony are (from left) Eduardo Fernandez, Gaspar Rodriguez, Michael Goolsby, Aaron Phillips, Alex Tigera and Jorge Acebo.

In the aftermath of 1992’s Hurricane Andrew, the entire building code for South Florida was rebuilt from the ground up. When it was launched in 1994, the South Florida Building Code was a groundbreaking document that set new roofing application standards and testing protocols for every component and system in the building envelope. More than two decades later, it was clear the building code for Miami-Dade County’s high-velocity hurricane zone (HVHZ) needed to be updated. Beginning in 2014, Miami-Dade County officials worked with the Asphalt Roofing Manufacturers Association (ARMA) and others in the roofing industry to ensure the current code language was clear and up to date.

Two-and-a-half years later, their work is complete. The 2017 Florida Building Code is scheduled for implementation on Jan. 1, 2018, and it will include every one of the proposals and public comments jointly submitted by ARMA and Miami-Dade. As a result of this successful collaboration, ARMA presented the Miami-Dade Regulatory and Economic Resources Department with the inaugural ARMA Public Partnership Award in 2017 for their work together in updating the building codes for the HVHZ.

Members of the joint task force on the project shared their thoughts on the experience with Roofing, including Mike Fischer, ARMA’s Vice President of Codes & Regulatory Compliance; Michael Goolsby, Miami-Dade Board and Code Administration Division Director; Jorge Acebo, Roofing Product Control Examiner; Alex Tigera, Roofing Product Control Examiner; and Gaspar Rodriguez, Code Compliance and Training Officer, Roofing.

They all believe this collaboration between industry and government could serve as a successful model for other industry trade associations and other code bodies to follow. “This kind of cooperation between a public regulator and a private trade association is rare enough,” says Fischer. “The overwhelmingly positive results are unprecedented.”

The Problems

Miami-Dade staff and ARMA representatives both saw shortcomings in the roofing requirements for HVHZ. There were outdated references that needed to be removed, including test standards that were out of date. This often resulted in questions that slowed down the product approval review process. Members of the roofing industry also wanted to explore coordinating the Miami-Dade HVHZ protocols with other national testing requirements to further streamline testing procedures.

Fischer summed up ARMA’s goals this way: “ARMA is a responsible advocate for the asphalt roofing industry. We take that role seriously. We are an advocate. Our job is to represent the collective interests of the producers, but we try to be responsible about it. And it’s that drive to be responsible which led us to this partnership with the Miami-Dade staff.”

At the first meeting between ARMA and Miami-Dade, Fischer tried to break the ice. “The first thing we said when we came into that meeting was, ‘Hi, we’re from industry and we’re here to help,’” Fischer recalls. “I will tell you that when we started that meeting in the morning, the Miami-Dade staff was probably skeptical of what we were there for. By the end of the day, we had laid out a project plan of how we were going to work together, and that set the tone for the rest of the project.”

Fischer knew it would take the two entities working together to get things done. “In the Florida process, we knew we had to work with Miami-Dade, as they are a key stakeholder. We brought in other roof covering manufacturers for some of the discussions, and we also talked to the FRSA, the Florida Roofing and Sheet Metal Association—the contractors—so they were at the table for quite a bit of this as well.”
ARMA set up a special task group to focus on the Miami-Dade protocols. The task force went through documents one by one with members of Miami-Dade group, identifying problems and sections that were out of date. They hashed out compromises when they didn’t agree.

Protecting the Public

Goolsby worked on the project on behalf of Miami-Dade along with members of his team including Acebo, Tigera and Rodriguez. “We cover a lot of territory,” notes Goolsby. “We maintain the building code and write the building code, but we also oversee all of the contractor licensing in Miami-Dade County. We have about 15,000 local licensed contractors. Of course, we handle product approvals, and we also service all of the boards here. We have a board of rules and appeals. We also oversee 35 building departments throughout Miami-Dade County. We try to make sure the code is uniformly enforced in all of those jurisdictions. So, we cover a lot of bases.”

The top priority is protecting the public. “In a general sense, we provide for the health, safety and welfare of the public,” Goolsby says, “But it’s these issues of life safety that are the most critical.”
Evacuating South Florida is difficult, so the residential portions of the code were written under the assumption that many people might have to ride out a storm in their homes. “We wanted their home to be just as strong as any commercial structure,” says Goolsby.

Acebo notes that ensuring the code is properly followed is as crucial as the code itself. He believes the inspectors’ role includes reassuring homeowners that systems are being installed correctly. “It’s important to us to fulfill our role to provide independent corroboration that the work is being done and installed properly,” he says. “The great thing about this particular effort is that it was truly collaborative. It was great to work with them and establish the language that was common with other jurisdictions or other certification agencies.”

Promising Results

Members of the joint task force agree that the changes make the code easier to understand. They also should streamline product approvals process.

“These updates definitely help the manufacturers get through the product approval process, specifically for Miami-Dade HVHZ requirements,” Fischer states. “It also helps the roofing contractor because we made sure the documents have the installation language updated, so it gives better direction to the installers of the products. And that trickles up to the general contractors in new construction, as it speeds up their processes and takes out some burdens.”

“At the end of the day, as a responsible advocate, one of ARMA’s main motivators was to make sure their industry’s products get installed the way they are intended to be installed,” Fischer continues. “That benefits the end user—the building owner and building occupant.”

Acebo agrees that the approvals process helps everyone—homeowners, contractors, manufacturers and inspectors. “If questions come out of the field from homeowners, manufacturers or contractors as to whether something is being applied or used properly, we can serve as that independent third party that doesn’t really have a stake in it other than to serve as an arbitrator who can clearly indicate whether something is right or not according to what has been provided and tested.”

The collaboration was so successful that the task force is already looking at other changes in the future. The Miami-Dade code is used as a model for other code bodies, and the joint task force could serve in that role as well, according to Fischer. “This is a model of collaboration between a governmental agency and private industry groups that will serve us well,” he says. “We are going to continue to do this with other groups, and frankly we’re going to continue doing it with Miami-Dade because this process isn’t ever done. Things will always be changing and we always have to keep up to date.”

Key Priorities for Fire Station Project Include Visual Appeal, Resistance to Algae and Wind

When the Burlington Fire Department decided to replace its aging steep-slope system, the goals included finding a system that would look good, stand up to high winds and resist algae growth.

When the Burlington Fire Department decided to replace its aging steep-slope system, the goals included finding a system that would look good, stand up to high winds and resist algae growth.

The firemen and firewomen of the Burlington Fire Department, located in Burlington, Wash., reportedly respond to about 1,800 service calls a year. The members of the department are on call 24/7, handling a variety of emergencies, both big and small.

Whether it is fighting a fire, performing a search and rescue, or something as simple as retrieving a driver’s keys from the car, the city’s bravest are too busy to have roof issues make their days more difficult. When the fire station began to experience leaks that required countless repairs and patchwork solutions, the City of Burlington knew it was time to replace the entire roofing system and ensure that the firefighters were safe from the elements.

Over the last few years, leaks began to appear more frequently in the fire station’s roof, with the worst leaks occurring in the paramedic’s quarters and in the firehouse’s workout room. The water would drip down on the firefighters and ceiling tiles became discolored, creating an unpleasant appearance throughout the firehouse. The intense winds in the area would also cause the shingles of the roof to become loose and fly off.

“The roof was patched several times over the years. We filled the voids as we went,” says Brandon Bond, a lieutenant on the Burlington Fire Department for the last 10 years. “After a while, the patches and replacements weren’t working and the leaks were getting harder to fix. At that point, we knew it was time to replace the whole roof.”

For their new roof, the city wanted a material that was visually appealing and performed against algae and wind. Also, because this was a city project, they wanted to find a contractor who was nearby and a roofing material that was manufactured locally—all of which showed pride in their community. When they considered the criteria, along with the size of the roof—24,000 square feet—the city chose to go with asphalt shingles because they provided a high level of longevity and durability while keeping it affordable.

Asphalt shingles offered a heavyweight, wind-resistant roofing material with a number of color options, making it the optimal choice among the design team. Wind resistance was an important factor because the old roofing system sustained considerable wind damage. The winds in the area can reach 65-70 miles per hour.

Selecting the Right System

Cascade Roofing Company from Burlington was hired to install the new roof on the fire station. The company has been in business for nearly 30 years and works on both commercial and residential roofing projects. The owner of Cascade, Rick Steiner, explains that asphalt shingles were used on the fire station for a number of reasons.

“Shingles were used because of the different pitch heights of the roof, their affordability and their great look,” Steiner says. “The algae-resistance was also a must. Algae grows like weeds in Washington, due to the moisture in the air and fluctuating temperatures.”

Algae flourishes in humid climates and its spores can be carried by the wind. The temperate but rainy weather found in the Pacific Northwest of the U.S. produces an environment for algae to thrive in. While algae is not known to cause damage to roofs, the dark streaks are unsightly.

“Burlington is very wet, whether it’s raining or if we’re dealing with the humidity,” says Lauren Wilkins, a firefighter at the Burlington Fire Department since 2012. “We wanted the new roof to provide some resistance to algae so that it looked good as compared to the other surrounding roofs in the area.”

Cascade used shingle manufacturer PABCO Roofing Products, located in nearby Tacoma, Wash. PABCO’s algae-resistant Paramount Signature Cut Shingle in Oakwood color was selected for the project because it provided exceptional curb appeal. An aggressive modified sealant was used as well as high-wind shingle application—6 nails—to add resistance to wind uplift. PABCO Paramount starter shingles were applied over PABCO Universal Starter to provide a double-layer base. A synthetic underlayment along with an ice and water shield on the leading edges were also used. Shasta HD Ridge was applied to the ridge and hips of the roof to complement the roofline.

The roof system was installed by Cascade Roofing Company using shingles manufactured by PABCO Roofing Products.

Keeping it Local

The City of Burlington was thrilled to choose local companies for the project. The manufacturer, contractor and even the supplier were all located nearby. This provided Cascade an avenue for necessary materials to be delivered quickly, allowing them to stay under budget and ahead of schedule. The project took about two weeks and 230 squares of shingles to complete, which is equivalent to the number of shingles necessary for the company to roof six or seven regular-sized homes.

“It’s easily the biggest shingle job I’ve ever done,” Steiner says. “But the design of the building along with the high-profile look of the shingles made the project look incredible. The city has a roof that’s going to last a very long time.”

Steiner also points out how smooth operations were due to the local theme of the project. “Everything was on-time. The supplier was right across the street and very easy to work with,” Steiner notes. “Even the weather cooperated – it made a potentially difficult project that much easier.”

The firefighters felt the same way. “We thought the hardest thing about the renovation would be continuing our daily operations, but we didn’t run into any problems,” Wilkins says. “They were very friendly and easy to coordinate with when moving equipment. There were no horror stories here.”

Since the renovation was completed, the firefighters are very happy with the new roof. The firemen and firewomen of the Burlington Fire Department can now focus on keeping the residents of Burlington safe.

The unique installation of the roof also earned Cascade Roofing and the fire station project the 2017 Bronze Award in the Asphalt Roofing Manufacturers Association (ARMA) Quality Asphalt Roofing Case-Study (QARC) Awards Program. Each year, ARMA seeks out the most beautiful, affordable and reliable asphalt roofing systems in North America.

Award-winning projects are selected based on innovation, performance and beauty, and recognize projects that lead the way in areas like weather protection, green roofing or unique utilization of asphalt shingles in a roofing system. ARMA is currently accepting submissions for both low- and steep-slope roofing project installations completed in 2017 for its 2018 awards program. Roofing contractors can submit multiple projects through Dec. 31, and there is no fee to enter.

ARMA Completes EPDs for Five Types of Asphalt Roofing

The Asphalt Roofing Manufacturers Association (ARMA) has completed a multi-year effort to develop Environmental Product Declarations (EPDs) for asphalt roofing systems. These five new documents provide information that building and construction professionals can use both to support environmental aspects of roof systems as part of sustainable building projects and to better understand their impact over time. EPDs are now available for asphalt shingle roofing systems, SBS and APP modified bitumen systems, and built-up roofing systems. 

When architects and specifiers embark on new green building initiatives, they need to validate the environmental aspects of the building materials they use. EPDs are used to provide this information and to support the credibility of environmental claims.  ARMA worked with thinkstep, a sustainability consulting company, and with UL Environment to validate the EPDs.  These comprehensive documents outline the environmental attributes associated with the manufacturing of various asphalt-related roofing materials. 
ARMA’s development of these five EPDs reflects the continued use and advancement of asphalt roofing materials. In some cases, these documents are needed to fulfill requirements for green building rating systems and initiatives such as Leadership in Energy and Environmental Design (LEED), Green Globes, and the International Green Construction Code (IgCC).

“As the worldwide building and construction community continues to expand the focus on creating environmentally responsible and resource-efficient building projects, asphalt roofing has a critical role to play,” said Reed Hitchcock, ARMA’s executive vice president. “ARMA is committed to supporting sustainable building initiatives, and we are proud to provide the industry with this important environmental information.”

“These EPDs will help architects and engineers make sustainable choices in roof design,” said Amy Ferryman, chair of ARMA’s Sustainability Task Force. “Our work to develop these resources helps ensure that the asphalt roofing industry can fully participate in increasingly important green building practices.”
The five EPDs from ARMA are now publically available and can be accessed on ARMA’s website.

ARMA Hires New Director of Technical Services

The Asphalt Roofing Manufacturers Association (ARMA) has named Tim McQuillen as director of technical services. McQuillen now serves as the staff liaison for ARMA’s Technical Resource Group as well as ARMA’s Codes Steering Group in a staff support role. He has been a member of the building products industry for 25 years.

In his new role, McQuillen will function as the technical voice of ARMA, leading the efforts on ARMA’s technical publications and communications while also responding to technical inquiries on asphalt roofing products and applications.

“ARMA is an association committed to educating and informing consumers and professionals through technical research and publications,” said McQuillen. “I look forward to contributing to these initiatives and more as we establish ARMA as the leading resource for asphalt roofing product applications.”

Prior to joining ARMA, McQuillen served as the technical manager of codes for Firestone Building Products Company, where he coordinated and executed product testing programs to obtain and document building code compliance.

McQuillen graduated from the University of Toledo with a bachelor’s degree in business administration. McQuillen is also a member of ASTM International and serves on the Technical Committee for the Cool Roof Rating Council (CRRC). He resides with his family in Westfield, Ind. 

“Tim’s wealth of technical knowledge in the field of building products will make him an invaluable asset to ARMA,” said Reed Hitchcock, ARMA’s executive vice president. “We’re excited to add another strong member to the ARMA team who provides a new level of expertise to our association and the roofing industry as a whole.”

ARMA Presents Public Partnership Award

The Asphalt Roofing Manufacturers Association (ARMA) has announced that the Miami-Dade Regulatory and Economic Resources Department is the recipient of the 2017 ARMA Public Partnership Award. 

The award, given only for the recognition of partnerships formed with ARMA, recognizes the collaboration between Miami-Dade and ARMA to update the Florida Building Code requirements in high wind zones. Aaron R. Phillips, corporate director of Technical Services at TAMKO Building Products Inc. and chair of the ARMA Codes Steering Group, presented the award to Michael Goolsby, Miami-Dade Board and Code Administration Division director. In addition, ARMA presented the staff members who worked on the project with individual certificates.

Over the past two years, Miami-Dade staff and ARMA representatives worked on updates to the roofing requirements for the High Velocity Hurricane Zone (HVHZ), during numerous meetings and conference calls to review the current provisions, develop code proposals and manage the Florida Building Commission process.

The collaboration spanned hundreds of hours to remove outdated references and coordinate the HVHZ protocols with national testing requirements. Revisions approved as a result of this effort will streamline the certification process for roofing manufacturers when launching new products or renewing existing approvals and help Miami-Dade staff manage their product approval review process.

“Miami-Dade staff members are grateful for ARMA’s recognition of our joint effort,” says Goolsby. “It was only through our shared goal that we were able to get it done.”

ARMA and Miami-Dade representatives attended the Florida Building Commission’s Rule Development Workshop in Ocala as the Commission approved the final changes. The 2017 Florida Building Code, scheduled for launch on January 1, 2018, will include every one of the dozens of proposals and public comments jointly submitted by ARMA and Miami-Dade.

“This kind of cooperation between a public regulator and a private trade association is rare enough,” says ARMA’s vice president of Code and Regulatory Compliance, Michael Fischer. “The positive results are unprecedented.”   
 
Phillips noted that the efforts aren’t necessarily over. “We hope to build on this partnership and continue to improve the product approval process during future Florida code updates,” he says.
 
ARMA’s efforts in the codes, standards, and technical arenas translate to effective minimum code requirements, useful material standards, and educational resources for the industry.  Technical manuals, installation guides, Fast Facts, and technical bulletins are available on ARMA’s website and provide best practices for a variety of roofing topics.  Visit the website for access to all of these materials and more.

ARMA Names Winners of 2017 QARC Awards Program

The Washington, D.C.-based Asphalt Roofing Manufacturers Association (ARMA) has named three winners of its annual Quality Asphalt Roofing Case-Study (QARC) Awards Program. The program seeks contractors who choose asphalt roofing and install beautiful and high-performing systems. This year, a stunning home in North Carolina, a commercial building in Florida and a firehouse in Washington state have been chosen as winners.

Chapel Hill Roofing Co. received the Gold QARC Award for its residential project titled The Triangle Home. The North Carolina-based contractor installed a full asphalt roofing system to fit the home’s complex architecture and the homeowner’s desire for a range of color options, protection from the elements and algae resistance at an affordable price.

The Silver Award was given to Advanced Roofing Inc., Fort Lauderdale, Fla., for the second year in a row. Its completion of a 49,955-square-foot roof on the Broward County Addiction Recovery Center’s Stephen R. Booher Building impressed judges with its intricacy. The new high-performance roof system provides weatherproof protection for the building’s residents.

Cascade Roofing Co., Burlington, Wash., was honored with the Bronze QARC Award for its steep-slope installation on the Burlington Fire Department firehouse. The building needed a new roof and required a product that had visual appeal, wind resistance and algae resistance. Cascade Roofing installed a full asphalt roofing system, including a synthetic underlayment and an ice and water shield on the leading edges.

ARMA received a record 40 submissions this year. These projects demonstrated the range of colors and designs that asphalt roofing can achieve, its ability to meet challenging project requirements and to provide reliability in tough climates. Each year, these projects are judged by a panel of roofing industry experts from trade associations, architecture firms and the media. Judges score projects based on their use of asphalt roofing technology to provide curb appeal, durability and value.

“As the QARC Awards Program has expanded over the last seven years, it has grown increasingly challenging for our judges to choose from the numerous excellent projects we receive,” notes Reed Hitchcock, ARMA’s executive vice president. “This year, it came down to identifying which projects demonstrated how contractors use asphalt roofing to solve key challenges for building owners and to provide peace of mind with a protective roof system.”

Two Commercial Installations Are Honored with ARMA’s QARC Awards

Advanced Roofing Inc. installed two new roofs at a luxury retired-living community in Palm Beach Gardens. These projects were Silver Award winners in ARMA’s 2016 QARC Awards.

Advanced Roofing Inc. installed two new roofs at a luxury retired-living community in Palm Beach Gardens. These projects were Silver Award winners in ARMA’s 2016 QARC Awards.

Commercial roofs are the workhorses of a building system. They endure wind, rain, hail and foot traffic while serving as an important line of defense between the outside world and a building’s occupants. If inhabitants never consider the roof over their heads, it means the roof system is doing its job well.

The Washington, D.C.-based Asphalt Roofing Manufacturers Association (ARMA) showcases these hardworking but rarely celebrated systems in its annual Quality Asphalt Roofing Case- study (QARC) Awards program. Each year, the organization seeks the top asphalt roofing projects in North America that demonstrate durability and high performance, as well as beauty. The QARC awards honor a Gold, Silver and Bronze winning project that illustrates the benefits of asphalt roofing.

The Silver Winner of ARMA’s 2016 QARC Awards is a prime example of what a commercial roofing system must stand up to while remaining water-resistant and durable. Advanced Roofing Inc. (ARI), which has service areas throughout much of Florida, was hired to install two new roofs at a luxury retired-living community in Palm Beach Gardens. These reroofs were completed in 2015 and were submitted to ARMA’s awards program.

The two buildings in this community were originally built in the 1990s and were found to have numerous issues that demanded immediate attention when new management reviewed the property. The area’s hot climate requires many air-conditioning units on the roof that frequently have to be serviced. This aspect of a commercial roof can be overlooked by building owners but has a significant impact on its service life and performance. Because HVAC units and related equipment are heavy and may require frequent maintenance that brings extensive foot traffic, they can cause a roof system to deteriorate faster than normal. That was the case with the existing roofs in this living community.

Toward the end of the roofs’ service lives, temporary fixes, like patching and coatings, were made. These regular repairs only increased the operational budget while the core issues remained unresolved. According to Jessica Kornahrens, project manager at ARI, “The existing roofing system was at risk of a failure that could potentially close the building and leave its elderly residents without a home.”

ARI was hired by the new building owner and property manager to tear off the existing roofs of these two buildings and install an asphalt roofing system on each. Because of the significant durability required by the new roofs, the roofing contractor chose a high-performance three-ply modified bitumen asphalt roofing system.

The two buildings in the retirement facility were still occupied during the reroof project, creating an additional challenge during installation, but the work came in on schedule and within budget.

The two buildings in the retirement facility were still occupied during the reroof project, creating an additional challenge during installation, but the work came in on schedule and within budget.


“We knew that this type of redundant, multi-layered system would protect these buildings long-term despite the high foot traffic and heavy equipment they have to stand up to while also meeting the project budget,” Kornahrens says. “This particular system also has a Miami-Dade Notice of Acceptance with testing and approvals for Florida’s high-velocity hurricane zone.”

Between foot traffic and harsh weather, the contractors knew this asphalt roofing system was up to the task.

Challenging Installation

Before they could begin the project, ARI had to first stop the existing leaks in the first 45,900-square-foot building and the second 51,000-square-foot building, followed by a tear-off of the roof system down to the light- weight concrete. ARI fastened the modified anchor sheet with twin-lock fasteners directly into the lightweight insulated concrete deck and then torch applied an interply and fire-retardant granulated cap sheet.
