Asphalt shingles with cool roof technology meet California’s homeowner demands and sustainability goals

California has long been a leader in sustainability initiatives, setting ambitious targets for everything from reducing greenhouse gas emissions to recycling. The net effect has had, and continues to have, significant implications for the construction sector. 

The state’s Title 24 Building Standards, for example, are some of the most stringent in the nation. They emphasize energy efficiency, water conservation, and the use of renewable energy sources in the built environment. This means that everyone from planners and developers to architects and general contractors must adapt their work and material choices to ensure responsible building practices that meet state guidelines and ultimately reduce their impact on the environment. 

In Northern California, sustainability in residential building initiatives is a rapidly evolving field, reflecting the state’s commitment to environmental stewardship and innovation. The focus is driven by both ecological necessity and a cultural inclination towards environmental awareness.

Even still, when faced with home improvement choices like roof replacement, California residents, like homeowners across the rest of the country, tend to factor sustainability in alongside other primary drivers: curb appeal and utility cost savings.  

One recent survey showed that home buyers—and especially younger home buyers—value a home’s exterior appearance over all else. In another study, 78% of home buyers expressed concern about their home’s environmental impact, but only 15% were actually willing to pay more for a home described as environmentally friendly—unless it offers utility cost savings, in which case 57% of respondents said they would pay $5,000 or more above the price of the home. 

On average, a roof accounts for about 40% of a home’s exterior, so it greatly impacts the aesthetics. With the right asphalt roofing products, homeowners don’t have to sacrifice aesthetics for sustainability. The range of asphalt shingles give homeowners a viable option to enhance the look of their home with an attractive roof, while upgrading its sustainable performance. 

Cool and Sustainable  

Northern California’s San Francisco Bay area is rich with beautiful residential architecture. Modern single-family tract housing dominates the hills and valleys of the area, along with more classic Victorian, Edwardian, and Craftsman homes. The roofs of these homes reflect the mountainous terrain that surrounds many of them: steep slopes of dark gray, black, and brown asphalt shingles.   

Thanks to their long-lasting durability, economical cost, and wide range of color and design options, asphalt shingles continue to be the top roofing material choice for homeowners in the United States. Roughly 80 percent of American single-family homes—four out of every five—feature an asphalt roof. That statistic is well represented in the suburbs of San Jose, where Los Gatos Roofing, a residential roofing contractor, averages 750 residential installations annually. Among their customer base, the CertainTeed shingles with Solaris Cool Roof Technology seem to be striking the right balance of design and color options, price point, and energy-efficient performance.  

Asphalt shingles are designed specifically to provide energy efficiency and superior protection against the elements. Solaris shingles feature a special granule surface blend that can reflect high levels of solar heat, which reduces roof temperatures and heat transfer into living spaces, lessening the workloads of air conditioning systems to save on energy costs. 

Malvern Pa.-based CertainTeed’s residential shingles featuring Solaris Cool Roof Technology. Solaris Cool Roof products comply with California Title 24, Part 6, Cool Roof requirements (per the California Cool Roof Rating Council). They also meet the more stringent Title 31 requirements for Los Angeles County. The large Solaris product portfolio features dozens of color options to suit any home’s aesthetic. All colors in the portfolio meet Title 24, Part 6, and most color options also meet Title 31. Solaris products may also contribute to LEED certification and other green building programs.  

Beyond Cool Roof Technology 

What happens before and after installation of asphalt shingles is just as important as what happens during their lifecycle. CertainTeed’s asphalt shingles are manufactured in roofing facilities that are actively reducing their impact on the environment through reduced water usage, lower manufacturing waste, and wind-powered operations. CertainTeed manufacturing facilities source 35% of their electricity from wind, and 86% of CertainTeed shingle manufacturing waste is diverted from landfills and routed to new use. 

Where shingles go at the end of their lifecycle is also a key consideration for sustainability. Approximately 13 million tons of asphalt shingles are landfilled every year. Fortunately, CertainTeed is building partnerships and investing in shingle recycling technologies to significantly reduce that amount by transforming end-of-life shingles into asphalt for roads. These approaches significantly lessen energy use, reduce landfill waste and demand fewer new raw materials.
