The more efficiently your roof reflects solar light, the more eco friendly it is. The Solar Reflectance Index (SRI) is used to measure the ability of how well a roof can reject solar heat. For a roof, the higher the SRI number the better. Metal roofing is considered the most energy-efficient. They are known to last up to 50 years or more and are extremely low maintenance.

Good ventilation is the key to keeping your roof cool. The three major types of roof vents that are utilized in residential roofing are static vents, wind powered vents, and eclectic vents. Having a proper energy-efficient roof offers more benefits than just a lowered cost on your energy bill.
