Eighty percent or more of the homes in the United States have roofs made of asphalt shingling, a roofing material that's cheap and easy to install. However, some homeowners are looking for improvements in efficiency, reflectivity, and longevity. Even if you have asphalt shingling, there are ways to make it more eco-friendly. Here are three criteria you can use to help you estimate whether your roof is eco-friendly or whether it needs modification or replacement to live up to your standards.
1. It's light in color or naturally reflective
One of the biggest ways to improve energy efficiency with your roof is to make sure it reflects away the light of the sun rather than absorbing it and transferring it into your house where it becomes your AC system's problem. If you live in a hot part of the country, you may already have a white or light-colored roof for this reason (and because sometimes AC units just can't keep up when they have both a hot climate and a hot roof working against them). If you don't have a light-colored roof or one that's naturally reflective, such as a metal or tile roof, you may want to consider either replacing your roof with a more eco-friendly material or simply covering it with a cool roof coating. A cool roof coating is a white coating that reflects not only light rays but also heat rays, making it even more effective than simply painting your roof white.
2. It doesn't accrue a lot of heat
Even if your roof is dark in color, you or a previous homeowner may have taken steps to prevent extreme heat gain through the roof. Some ways to do this include installing extra attic insulation, using a radiant heat barrier to reflect heat back out through the roof, and making sure the attic has ventilation and fans to remove heat from the attic before it seeps into your living space. Preventing the sun's heat from reaching the roof by comprehensively shading it (whether with shade trees, shade cloth, or shade sails) can also keep it from soaking up as much heat as it otherwise would.
3. It's made of reclaimed or recycled materials
Did you know that you can recycle used roofing shingles? It's cheap to do and may even cost less than sending the shingles to a landfill, depending on local availability. You can also buy shingles made from old recycled roofing shingles. But an even more eco-friendly option is using reclaimed roofing materials (such as reclaimed tiles or slate), which don't require processing before reuse like the recycled materials do and consequently take even less energy.
These three things will help you to evaluate your roof for its eco-friendly properties and decide whether you want to keep it as is, add a cool roof coating or some shade, or even replace the roof with another material entirely.
