Envirogen™ is a family of Malarkey Roofing Products® specially designed, manufactured and certified for sustainability. These shingle products are designed with a goal of sustainability in focus through each step of the product’s life cycle. From a shingle’s manufacture to the end of its service life, Malarkey shingles are created for superior performance, reliability, and limited impact on the environment.
Malarkey worked with the Asphalt Roofing Manufacturers Association (ARMA) to complete an Environmental Product Declarations (EPD) focused on steep and low slope roof systems. An EPD is a standardized way to understand the sustainable qualities of a product and its environmental impact over time.
In the roofing business since 1956, Malarkey Roofing Products® is a company perpetuated by the success and foresight of previous and current generations. With a keen ability to innovate, the company has advanced modern roofing materials by engineering solutions to common roof problems. Today, Malarkey is dedicated to keeping its roofing materials out of the waste stream and preserving the quality of life on our planet.
Polymer Modified Asphalt was created with sustainability in mind, and is now greener than ever before.
Styrene Butadiene Styrene
Looking for an alternative to conventional oxidized asphalt during the oil crisis in 1975, then company President Michael Malarkey traveled to Europe, where he was introduced to the process of modifying asphalt to make it more flexible and extend the material’s life span. Malarkey Roofing Products® applied this technology to introduce the first Styrene-Butadiene-Styrene (SBS) polymer modified base sheet to North America in 1977.
Malarkey Roofing Products® has continued to enhance the recipe for polymer modified asphalt. Introducing the first SBS roofing shingle to the industry in 1986, the flexible properties found in SBS asphalt were the perfect solution as they allow for cold weather installation down to 0˚F (-18˚C), which is 40 degrees lower than standard oxidized asphalt shingles.
Recognizing the benefits of SBS for asphalt shingle technology and improved shingle performance, the formula was refined to create Flexor™ polymer modified asphalt. In 1997, Malarkey expanded the product line to include laminate shingles and created the Legacy®, the first SBS modified laminate shingle. The Legacy® is rated at UL 2218 Class 4 impact resistance and among the most popular of Malarkey’s product offerings.
The greater flexibility and impact resistance of the Flexor™ material also prolongs the life cycle of the roofing products, keeping them out of the waste stream. Utilizing Flexor™ polymer modified asphalt eliminates the atmospheric contaminant by-products of asphalt production. Flexor™ polymer modified asphalt is exclusively blended for our Windsor® and Legacy® shingle lines, as well as EZ-Ridge™ and RidgeFlex™ hip and ridge shingles.
Nexgen™ polymer modified asphalt takes Flexor™ to the next level by combining it with repurposed materials while maintaining a high level of quality performance. In 2016, Malarkey began combining a blend of Flexor™ asphalt with polymers from plastic milk jugs, markers, and rubber tires. These polymers improve the performance of the shingle, significantly improving the asphalt’s flexibility, granule adhesion, cold weather installation, and impact resistance. The Vista™ shingle line was the first to be fortified with Nexgen™ polymer modified asphalt, followed by Ecoasis™ Costa and Dura-Seal™ shingles. Vista™ and Dura-Seal™ are shingle lines offering optional security against algae staining. The Vista™ shingle line is rated with Class 3 impact resistance and the Dura-Seal™ shingle line is rated with Class 4. Ecoasis™ Costa is a solar reflective shingle also rated with Class 3 impact resistance.
With 60 years of experience manufacturing roofing materials, the successful debut of the Vista™ is largely attributed to the use of repurposed polymers in the ongoing effort from Malarkey to promote sustainable roofing materials.
Repurposed Polymers from Reclaimed Plastic and Synthetic Rubber
Malarkey Roofing Products® is deferring waste from entering landfills by reducing our need for new synthetic materials. With our Nexgen™ polymer modified asphalt, the next generation of asphalt shingle technology, specific polymers sourced from repurposed materials are included to enhance performance characteristics of the shingle. The environmental results are significant.
At each manufacturing facility, Malarkey uses repurposed materials for shingles featuring Nexgen™ polymer modified asphalt. At this scale of production, the reduction of environmental impact is substantial. For every ton of recycled plastic or synthetic rubber used, 4 barrels of oil and 7.4 cubic yards of landfill space are saved. Additionally, for every pound of recycled tire rubber used, one pound of carbon dioxide is prevented from being released into the atmosphere.
An average-sized roof* with Nexgen™ asphalt shingles feature roughly 5.5 tires and 350 milk jugs.
*An average-sized roof for these purposes = approximately 25 squares
Cool Roofing Granules
Cool Roofing Granules reflect solar ultraviolet (UV) rays, the infrared portion of sunlight. This enables the colors of the shingle to be seen by the eye, while still allowing the roof to stay cool.
Roofs with these reflective granules can also keep the building cool, and may reduce energy use to control air-conditioning. Cool roofs can also aid in reducing the heat island effect in developed, urban areas.
Malarkey products with Cool Roofing Granules include:
• RCap™ Line: As part of a roof system, solar reflective cap sheets may help decrease building energy costs and extend roof service life.
• Ecoasis™ Costa with Nexgen™ polymer modified asphalt: Ecoasis™ Costa is an architectural shingle featuring solar reflective granules similar to standard shingle colors and fortified with sustainable Nexgen™ asphalt.
Malarkey’s products with Cool Roofing Granules have measured radiative property values listed with the Cool Roof Rating Council and can be used to comply with California Energy Code Title 24, Part 6 Cool Roof Requirements.
Streak Resist™ Technology
Malarkey also utilizes specialized granules that perform beyond traditional materials to offer benefits to the homeowner and the environment. Algae growth on a roof can cause black streaks which can alter the color of your roof and make it appear aged. Streak Resist™ Technology is a blend of algae resistant copper granules that help maintain the aesthetic appearance of your roof by resisting black streaks caused by algae and may reduce the need to clean your roof.
Scotchgard™ Protector from 3M
Also available to protect homes from unwanted algae growth are Malarkey shingles featuring Scotchgard™ Protector from 3M. These shingles feature 3M™ Copper Roofing Granules, developed to protect against the growth of algae and help prevent black streaks from forming on roofs in climates with especially high humidity. In 1994, Malarkey Roofing Products® became the first manufacturer to offer Scotchgard™ Protector in a shingle.
Durable Roofing Shingles Avoid Landfills
Malarkey Roofing Products® manufactures performance-driven shingles that withstand extreme weather conditions with an extended service life on the roof.
Both Flexor™ and Nexgen™ polymer modified asphalts offer exceptional flexibility. This flexibility, plus the use of SEBS seal-down adhesive, prevents shingle blowoff, making the shingle more durable and less likely to create waste. As compared to traditional oxidized asphalt, Flexor™ and Nexgen™ products provide a longer life cycle.
Other attributes, such as impact resistance, allow shingles to withstand hail damage, lessening the impact of tear-offs and waste. Shingles featuring Copper Roofing Granules prevent algae growth which can also limit the life of the shingle.
Perhaps the most sustainable Malarkey innovation at present is the Nexgen™ polymer modified asphalt made at all manufacturing facilities. Nexgen™ is made from repurposed materials and being produced with a repurposed energy source via the methane recovery pipeline in the Portland, OR facility (see the Governor’s Achievement Award on back cover for details).
Asphalt Shingles are Recyclable
At the end of their useful life, asphalt shingles can avoid landfills and be recycled in most major metro areas. The shingles are ground up and used widely in paving applications. To learn more about how asphalt shingles are recycled, visit the Asphalt Roofing Manufacturers Association website.
GreenCircle Certification (2015, 2016)
GreenCircle provides third-party certification of sustainability claims through a rigorous scientific evaluation based on internationally recognized standards and guidelines. All three of Malarkey’s asphalt roofing facilities have achieved the Waste Diversion from Landfill certification, demonstrating responsible management of end-of-life materials.
In the GreenCircle certification process, diversion, and reduction can be achieved through a combination of approved methods. Malarkey utilized the methods of source reduction, recycling, energy recovery, and reuse of materials to achieve waste diversion from landfill thresholds.
The evaluated Malarkey facilities achieved diversion rates of 89 percent or greater as follows:
• Portland, Oregon – 94 percent waste diversion. See certificate here.
• South Gate, California – 93 percent waste diversion. See certificate here.
• Oklahoma City, Oklahoma – 89 percent waste diversion. See certificate here.
The Portland location has a fiberglass mat facility on site, which was not included in this analysis in order to achieve a more direct comparison to other facilities in the industry. Malarkey plans to pursue separate certification for the mat facility at a later date.
100 Best Green Workplaces in Oregon (2016)
Malarkey was ranked as number 90 among the 100 Best Green Workplaces in Oregon. More than 15,000 employees and volunteers from the for-profit and nonprofit sectors took part in the survey. Participants come from a variety of sectors, including tech, professional services, manufacturing, and auto.
Oklahoma City Storm Water Award (2016)
For outstanding achievement in storm water management, Malarkey’s Oklahoma City manufacturing facility received an award in 2016. The facility acquired this distinction by accurately measuring and improving management practices for storm water pass way protection. Beginning with 89 percent waste diversion from the landfill (certified through GreenCircle), the facility already realized a significant reduction in the polluting of the storm water system. From there, the team installed grating and filters over storm water inlets to reduce the chances of debris entrance. A movable containment cart was also fabricated to place under trucks while offloading material to act as spill containment, and an awning was built to cover all roll-off trash containers. Lastly, members from the Malarkey team participated in a Litter Blitz trash pick-up organized by Oklahoma City Beautiful.
Governor’s Energy Award for Outstanding Achievements in Energy Conservation (1985)
Malarkey Roofing Products® earned this award for reducing its natural gas consumption by over 80 percent. This feat was accomplished with the installation of a methane recovery pipeline to the company’s manufacturing facility from a nearby wastewater treatment plant.
The City of Portland’s Columbia Boulevard Wastewater Treatment Plant, managed by the Bureau of Environmental Services, is Oregon’s largest wastewater treatment facility, cleaning about 30 billion gallons of water a year. The process generates about 1.5-million cubic feet of methane gas every day.
Malarkey began construction on the pipeline in 1983 to transport methane gas to the manufacturing facility one mile down the road. The initial investment for Malarkey was sizable but aligned with the core sustainable values of both facilities. Once the pipeline was completed in 1984, methane from the plant was used for the facility’s product manufacturing – from curing fiberglass mat to providing the process heat source for shingles and other asphalt roofing products. Today, Malarkey continues to operate this pipeline and has a historical average of 67% of the roofing manufacturing facility powered by gas from the wastewater plant.
