- Reflectance — High solar reflectance is a property found in most roofing products that are energy-efficient. Rather than absorbing energy from the sun, these products reflect it into the environment. Less heat will enter your home, as a reflective roof may reduce your roof’s surface temperature by up to 30%.
- Emittance — High emittance is found in an energy-efficient roof, which means the roof is highly efficient at releasing absorbed solar heat.
- R-Value — The energy efficiency of your roof can be increased by adding more insulation. The R-value of a roof will measure the insulation’s ability to resist heat transfer. This is especially useful in colder climates, as materials with a high R-value can trap heat in a home and ultimately lower heating costs.
- Life Span — The longer a roof lasts, the less of an impact it will have on the environment. A 50-year roof will mean that the material does not have to be recycled or placed into a landfill for much longer than a 20-year roof.
Use The Right Materials For Going GreenOne of the easiest ways to create an environmentally friendly roof is by using materials that are considered green. Green designs can make a home much more energy efficient. And there are many different choices that work for both residential and commercial properties.
- Corrugated Asphalt Roofs — A corrugated asphalt roof uses material that is half from a recycled product that would have otherwise ended up in the landfill. It is designed to provide just as strong and durable a roof as any other asphalt product.
- Shingles From Recycled Material — Asphalt shingles, wood, rubber, and plastic can all be used to make shingles from recycled materials. The recycled shingles will look the same as shingles made from new, raw materials.
- Foam — Foam roofing is a new green material, and offers some great advantages for the environment. Foam roofs can last the lifetime of a home, and they offer great protection from rain and the other elements. The foam roofing insulates the home when it is used. That means the home will require less energy to heat and cool.
