When designing and building your new roof, the two key elements you should think about are the material and the color. A high performance roofing material coupled with a well insulated attic will help to keep your home warm in the winter and cool in the summer. Your roofing material is the final layer of protection from the outdoor elements and from indoor heat loss. When deciding what’s green and what’s not, you should consider several aspects of a given material. These include the raw material source and composition, durability / life cycle, maintenance, and disposal. You can learn more about sustainable roofing options in the latest issue of Home Ideas.
