When the roof of The Triangle Home started to leak, the homeowners knew it needed to be replaced immediately. They worked with Chapel Hill Roofing Company of Chapel Hill, North Carolina, to identify the right product for their needs. The homeowners researched every type of roofing material, from slate to wood shake and metal. Ultimately, they chose asphalt shingles because they provided more color options, protection from the elements and algae resistance properties. The affordability was also an important factor. The homeowners were delighted to discover that they could get a beautiful roof at a price well below that of real cedar shake. Chapel Hill Roofing installed a CertainTeed Integrity Roof System™, which consisted of Landmark® shingles in the color Pewter; WinterGuard® ice and water barrier; DiamondDeck® underlayment; SwiftStart® starter shingles; CertainTeed Ridge Vent; and Shadow Ridge® accessory shingles on the hips and ridges. The complexity of the roof made for a challenging installation, as there were many different roof slopes and 11 skylights that had to be replaced.
The 49,955-square-foot roof of the Broward County Addiction Recovery Center’s Stephen R. Booher Building was facing numerous leaks. Advanced Roofing, Inc. (ARI) in Fort Lauderdale, Florida, was called upon to build a new, high-performance roof system that would provide the weatherability needed to protect the building’s residents. A Johns Manville SBS modified bitumen membrane, DynaLastic® 180 S, was selected as the base sheet. The base sheet was mechanically fastened and the laps were heat welded. All subsequent layers—the DynaWeld™ Base sheet and DynaWeld™ Cap FR CR — were also heat welded. In areas with low flashings, JM PermaFlash® was utilized to terminate the roof system. The SBS modified bitumen roofing system was chosen for the low-slope portions of this roof to provide a proven system with the durability to withstand the torrential rainstorms and high winds common in Florida. Installing a roof of this magnitude requires significant skill and work. ARI was able to complete the project on time and within budget.
The Burlington Fire Department was in need of a new roof, due to existing leaks. They contracted with Cascade Roofing out of Burlington, Washington. The building required a product that had visual appeal, wind resistance and algae resistance. PABCO® Roofing's Paramount® Signature Cut Shingle in Oakwood color became a favorite among the design team. The roof is 209 squares, or about the size of 6 or 7 standard homes. On such a large building, asphalt shingles provided the best longevity and durability for the price per square. This was a heavyweight shingle, and provided curb appeal, superior seal-down and protection from the elements. Cascade Roofing installed a full asphalt roofing system, including a synthetic underlayment and an ice and water shield on the leading edges. By successfully finding a local manufacturer and supplier, and by coordinating product delivery, Cascade ensured a seamless process for the building owner that met the project’s budget and installation requirements.
Asphalt roofing systems have the distinctive ability to provide superior durability and protection while also enhancing unique architecture. John Foster, a roofing contractor in Esparto, CA, was tasked with updating the appearance and resilience of this incredible star-shaped home. The home’s original owners designed the structure around the Lone Star to honor their Texas roots. Sitting on a range of cliffs overlooking the Pacific Ocean with no protection from storms and high winds, the homeowners needed a roof that could perform in a challenging climate. The contractors chose PABCO Roofing Products Premier Advantage Granite shingles because of the product’s exceptional wind resistance and ability to endure the damp, salty coastal environment. The shingles’ color and design complemented the look of the home without getting lost in the bold architecture. Despite a challenging design, the contractor successfully installed an asphalt roofing system that met the rigorous aesthetic and performance requirements of the project.
Located at the prestigious PGA National Resort and Spa, Devonshire is a picturesque 26 acres that serves as Palm Beach Gardens’ premier address for catered retirement living. The property consists of three buildings, two of which Advanced Roofing Inc. (ARI) was called upon to reroof in 2015. The Court and Cove buildings suffered from roofing issues that demanded immediate attention. The two roofs’ numerous air conditioning units were frequently serviced, resulting in high amounts of foot traffic and use of heavy equipment. ARI, of Fort Lauderdale, FL, selected a high-performance SOPREMA three-ply SBS-modified bitumen roofing system that would satisfy Devonshire’s need for durability while meeting their performance and budgetary requirements. The asphalt roofing system consisted of durable, water-resistant layers, including a SOPREMA base sheet and cap sheet, that delivered a pristine appearance, addressed the unique needs of both buildings and corrected past roofing issues.
When it came time for the Miami-Dade Public Library System to construct a new facility for the Northeast Regional Library, the building owner chose a hybrid built up/SBS-modified bitumen asphalt roofing system. They were interested in the durability, performance and longevity of built-up roofing. Precision Roofing Corp. of Hialeah, FL, had extensive experience installing these types of systems and knew they were built to last. The GAF roofing system installed on the new library utilized three plys of GAFGLAS® Ply 4 Ply Sheet and a Ruberoid® EnergyCap™ 30 Granule FR membrane. The finished product delivered a high-performance and durable system that met the project’s budget restrictions and will protect the structure for years to come.
A school's roof must be able to provide long-lasting durability and high-performance that will protect students, staff and equipment from harsh weather while still meeting a school district's budget. After decades of enduring the hot sun, freezing snow storms, heavy wind and hail, the roof of Thomas Jefferson High School in Denver, Colorado, had been compromised and was at risk of leaking. Denver Public Schools relied on low-slope asphaltic roofing to deliver the protection required while meeting energy-efficiency standards and low-maintenance cost requirements. The district chose a BUR system to protect the school and save money. "BUR is a premium product offering an unsurpassed level of security that is needed with Colorado's intense weather, especially the hail," said Michael Butler, project manager for Denver Public Schools. The new roofing system incorporated a Johns Manville GLASPLY® Premier Type VI base sheet and Perlite Cover Board, two layers of ENRGY 3® insulation and four plies of GLASPLY® Premier Type VI felt. Due to asphalt roofing's ease of installation and reliability, D&D Roofing was able to meet the project deadline and provide the school district with peace of mind knowing their building is protected by multiple layers of water-resistant technology.
The Grand Lodge at Deer Valley Resort in Park City, Utah, which sits at an elevation of 9,000 feet, was originally roofed with concrete tile. The building was losing a tremendous amount of heat through the roof, causing snow to melt and refreeze on the eaves. Residents were regularly disrupted by the heavy equipment including chain saws that were being used to cut through the ice that formed atop the five-story building. IronClad Exteriors, Inc. was hired to install a new steep-slope asphalt shingle roof on the lodge. The contractor removed the concrete tiles and installed CertainTeed FlintBoard™ ISO NB Composite Polyisocyanurate/OSB Roof Insulation. Next a fascia board was installed, followed by a WinterGuard® HT advanced waterproofing underlayment and DiamondDeck® High Performance Synthetic Underlayment. The final and visible layer consisted of the Presidential Shake™ shingle product. IronClad Exteriors, Inc. chose asphalt shingles for their beautiful aesthetics and long-term durability.
This beautiful home in North Lake Tahoe was purchased by the homeowners in January of 2014. The original roof consisted of a beautiful wooden shake that the homeowners loved the look of. Since the home is located in a heavily-wooded area, the couple worried about the roof catching fire. They hired Tom Goldston Roofing to install a fire-resistant roofing system that would resemble the look of the original shake material. The roofing contractor chose PABCO Paramount Advantage® Oakwood Signature Cut asphalt shingles that at 495 pounds per square provided the thickness and color that the homeowners desired while meeting their fire-performance requirements. The homeowners love the look that their new roof gives their home and can now rest assured that their property is protected by fire-resistant asphalt shingles.
Government buildings are under tight scrutiny to not only protect assets, reduce cost and assure longevity, but also respond to the ever growing need for installing energy-efficient roof systems. Doral City Hall is the perfect example of how asphaltic roofing does it all. The system consisted of multiple roof areas, including lightweight insulating concrete that used a nailable venting base sheet, 3 plies of premium glass ply, and an energy-efficient cap sheet that exceeded the reflectance requirements of ENERGY STAR®, Title 24 and the Miami 21 Initiative. Another roofing area was built over structural concrete.
This system incorporated the use of GAF GAFGLAS® Stratavent® Eliminator™ venting base sheet directly over ISO insulation, which also helped reduce the overall cost of the project by eliminating the need for an overlay board and a mopping of asphalt because Precision Roofing Corp. could simultaneously attach the base and first interply. Because the architect specified a roof that would last, Precision believed in the durability and reliability of this redundant system. Using innovative asphaltic roofing products like the highly-reflective EnergyCap® BUR cap sheet, they were able to meet high
Publix Super Market, one of the top 10 largest supermarket chains in the U.S. with over 165,000 employees, trust their roofing specification to a composite built up/modified bitumen system. Advanced Roofing is one of Publix’s preferred roofers and have installed asphaltic roofing systems for the company since 1996.
Publix chose asphaltic roofing because they believe it’s the best system to keep their products dry and customers safe. They weren’t comfortable with a single ply of protection, instead they prefer the redundancy of asphalt. Store 1382 in Miami, included a metal deck, 2 layers of ISO installed in accordance with FM Global requirements, a GAFGLAS® Stratavent® Eliminator™ Perforated venting base sheet, 3 plies of FlexPly ® 6 and a GAF PRF SBS FR Modified bitumen cap sheet. It was finished with an ENERGY STAR® rated coating that not only made the roof look great but also helped reduce energy costs and fight global warming.
Advanced Roofing recommends the use of asphaltic roofing to any professional looking for a bulletproof roof. It not only provides multilayer protection, but has a 100+ year track record, waterproofing and adhesion characteristics.
Formerly known as Phelps Mansion, this historic Victorian was built in 1888 by Edward Phelps, who was the first mayor of Laurel, MD. During his 7 terms in office from 1895- 1902, he was responsible for bringing electric street lights, brick-paved roads, a telephone system and a railroad that connected Laurel to Washington, D.C. During renovation, Certainteed Highland Slate was chosen primarily because it imitated natural slate, which was a period material for this historic home, and it was significantly cheaper than any slate or synthetic roofing product. It was also one of the few products that the local historic commission would approve for this home in order meet their stringent guidelines. Unlike other slate options, this asphalt product was easy to work with and provided a safer working environment. As noted in the pictures, this asphalt roofing product works great on historic buildings that are trying to replicate an original look and feel. Ceritified Incorporated highly recommends using this asphalt roofing product to other contractors working on historic restoration projects.
It may not sound like a massive project when considering building size alone, but when combining the other requirements — creating a roofing system that would assure redundancy and long-term performance, accommodating over 800 stand-up solar panels and meeting the stringent requirements dictated by CA Title 24 — the complexity of the build rose significantly. Working together as a team with their specifiers, the general contractor and GAF, the manufacturers for this project were able to master each and every hurdle. The system included EnergyGuard™ Tapered Iso, and over lay of EnergyGuard Perlite, GAFGLAS® Ultima 80™ base sheet , 2 plies of GAFGLAS FlexPly™ 6 and GAFGLAS EnergyCap™ BUR Mineral Surface Cap sheet. A base, two plies and a cap is a common spec in California, but nothing about this job was common. Complex and beautiful, yes, but common, no. BUR rose to the challenge, providing a reflective, redundant, compliant roofing system that meets the needs of today, and as an energy-efficient facility, the needs of years to come as well!
Robert Vankregten is a retired ship captain and engineer. He and his wife, Alma, live in an upscale neighborhood called "Evergreen" in Mill Creek, Washington. Evergreen and other surrounding communities are governed by the Mill Creek Community Association (MCCA). MCCA's roofing standards are some of the highest in the state and are often adopted by other upscale homeowners associations within the area. Their acceptable roofing products are tile, slate, metal, cedar shake, and a few heavyweight asphalt shingles. First and foremost, the homeowner wanted a roof that would last a long time, look good on their home, and require low maintenance. They also wanted it to look like their existing cedar shake roof and accent the color of the home and the extensive brickwork on the siding and chimneys. Living in the Northwest and in a development that has numerous trees and an abundant amount of rain, the homeowners also wanted a roof that wasn’t “noisy” when it rained nor easily susceptible to algae growth or color fading like some of their neighbors’ roofs. Having considered all factors, they chose the PABCO Paramount Advantage® Heavyweight Signature Cut Asphalt Shingle in the color Oakwood. The limited lifetime warranty, the 110-mph wind warranty, and the Scotchgard™ algae-resistant warranty made it easier for them to choose this roofing product.
Once installed on this steep hip-roof, it closely duplicated the appearance of the old cedar shake roof. These heavyweight asphalt shingles will last three times as long as the cedar shakes and will require little to no maintenance.
The homeowners were absolutely thrilled with their completed roof! Since completing this project, the roofing contractor has installed several other roofs in the Evergreen community and in surrounding neighborhood's using the same products with different colors.
The environmentally-conscious owner initially specified a 2-ply modified bitumen system with a cool roof coating. Before tear-off started, however, the owner asked AR&M to research a vegetative roof option and very quickly the “cool” top coat was replaced with a “greenest of green” vegetative solution. The JM modified bitumen system still remained the very best solution under a vegetative system. It is watertight, durable and will hold up for years, according to AR&M’s project manager Troy Huffman. The stainless steel leak detection system laid over the DuraBoard® insulation allows any future water leaks to be pinpointed to the exact square inch. A possible “suck back” issue due to the building’s negative air pressure was resolved by using the JM urethane adhesive to adhere the DynaWeld™ base sheets at all perimeter walls, past the first joint in the DuraBoard® insulation, and at a minimum of three feet from the penetrations. The two plies of base and the cap sheet were then torched down with no adverse issues and AR&M’s ‘green team’ installed the multilayer vegetative roof system.
The asphalt roofing system on this residential project located in Deerfield, Illinois, embodies the qualities that the program strives to recognize each year: beautiful, affordable and reliable. With the installation of a new, designer, double-laminate shingle, it was the first of its kind to be used in the Chicago area. Installed on multiple roofing planes, attention to detail was paramount to the roof’s uniform appearance. The homeowner desired the aesthetic appeal of a slate roof without the high cost and expensive installation of slate. This new shingle is a departure from the traditional architectural shingle that we see so much of today, giving the home the unique curb appeal that the owner desired and making it the envy of the neighborhood.
Flexibility was key for this project. With the house’s unique dome shape, asphalt shingles were required for this roof’s triangular sections and dramatic slope. Heavier roofing materials like metal and slate would have proved too cumbersome for this tornado-prone area. Asphalt’s versatility is showcased on this house as the different sized roof planes are seemingly tailored with designer asphalt shingles in a classic burnt sienna color. Because of the dry, warm climate in Texas, the high fire-resistance rating of asphalt shingles made it the obvious choice over other roofing materials like wooden shake. A combination of unique design and practicality makes this project a success story for asphalt shingles.
The most expansive project in this year’s program, this 257,000-square-foot roof is covered with an asphaltic modified bitumen system. Because of Florida’s climate, including an intense UV light and strong winds during hurricane season, an asphalt modified roof was the clear-cut choice for this building. Boasting 140-mph wind resistance and an ENERGY STAR® rating, the owner can rely on the roofing component to be durable and that the energy costs will be reduced over time. Affordability and ease of installation made asphalt the material of choice for this project.
Located in Montgomery, AL, this courthouse turned to asphalt to adhere to strict design criteria in a historical district. While not seen, asphalt underlayments play a key role in providing a watertight roofing system. Due to the tough access and difficult roofing, the modified roofing made it easier than installing a comparable single ply membrane. The self-adhering base sheet allowed an easier installation and the SRI on the cap sheet was as high and higher then some single plys. This asphalt system is aesthetically-pleasing, waterproof and includes the specifications to meet energy codes and historic codes without sacrificing quality.
This Dallas, TX, renovation project dealt with many challenges to complete the roofing system. From the removal of four layers of existing roofing, to being able to withstand standing water, to the 48 new roof drains, to the difficulty in staging and safety requirements during construction, the final product doesn’t fall short to the challenges that stood before it. The asphalt system went down easily and quickly, and the checkerboard design, with the Mosaic logo on the highest roof level, there will be a long-lasting impression on the Dallas skyline. As to the motivating design criteria, the Owner of the Mosaic wanted a memorable finished product ... which as mentioned previously, was definitely achieved!
The loan residential winner for the firs QARC program from Raleigh, NC, showcased asphalt shingles and how they can make a roof the main attraction. With longevity, the ease of installation and the multiple planes covered on the roof, it was a “no-brainer” to turn to asphalt for this project, and it’s a good example why four out of five homes are covered by asphalt shingles in the U.S. This case study allowed Baker Roofing Co. a chance to highlight how asphalt can drastically transform a home’s appearance, and make it the envy of the neighborhood.
