We all want to ensure a healthy environment for future generations and the roofing industry is no exception. Over the past decade, we’ve seen some great strides in eco-friendly roofing materials and designs. Our customers are asking for more green roofing options and we’re meeting their needs by offering roofing materials that meet the building industry’s definition of sustainability.

What Is a Sustainable Roof?

There are many different interpretations of sustainability and how it applies to roofing systems, but we happen to like the definition presented in the book, “A Primer on Sustainable Building,” by the Rocky Mountain Institute, Green Development Services. It defines a sustainable design as one that “takes less from the earth and gives more to people.” And that’s exactly what a sustainable roof does. It features recycled materials (taking less from the earth) and delivers energy efficiency and other green and renewable benefits (gives more to the people).

The Roofing Annex uses several types of sustainable roofing materials and techniques. They include metal roofing, ceramic roof tiles, reflective roofing, polymer roofs, composite or synthetic roofing and photovoltaic panel systems. These materials meet Energy Star and Leadership in Energy and Environmental Design (LEED) standards.

They also meet the main criteria for being sustainable:

1. They are made from recycled materials.
2. They provide green benefits, such as energy efficiency, less pollutants and extended lifecycle.
3. They are recyclable and can be repurposed in the future.

Benefits of a Green Roof

Research has proven that sustainable roofs have a positive impact on the environment. As an added benefit, a green roof also provides the homeowner with some nice savings. Take a look:

• Saves energy and produces energy. According to studies conducted by the Center for Environmental Innovation in Roofing, sustainable roofing systems have the potential to save over 700 trillion BTUs each year. Furthermore, solar energy produced by certain sustainable roof surfaces can power more than 12 of Washington’s Grand Coulee dams.
• Lowers energy bills by reflecting ultraviolet (UV) rays, thus requiring less energy to cool the home.
• Resists weathering and UV damage so the roof lasts longer, saving the homeowner money and reducing construction waste. The U.S. Department of Energy’s Energy Efficiency & Renewable Energy calculates that roofing materials add up to more than 40 million tons or 5% of all solid waste generated in the U.S.each year.
• Improves environmental health with a more eco-friendly installation that reduces or totally eliminates hazardous adhesive fumes or toxic odors.

What to Look for in Sustainable Roofing Materials

The availability of green roofing materials continues to increase as manufacturers combine science and technology to create more environmentally-friendly roofing choices. But how do you know which eco-friendly roof type is best for your home? Besides relying on the expertise of the Roofing Annex, here are three factors to consider:

1. Recycled Content: Inquire about the roofing material’s recycled content. The higher the percentage, the more green it is. Also check that the roofing can be recycled once its lifecycle is met.
2. Reflectivity: If you reside in a climate where it’s hot almost year-round, roofing that reflects the sun rays off your roof will keep your home cool. Generally, roofing materials that are light in color have the highest reflectivity.
3. Toxin-Free: Discuss the coating used on roofing materials and their upkeep. You want to stay away from materials coated with zinc or copper because the substances can wash off in harsh weather and end up in water sources where they can harm aquatic life. You also should find out if toxic products are necessary to maintain the roofing type.

The Roofing Annex is a key supporter of sustainable roofing materials as a means of ensuring a healthy planet now and for future generations.
