Roofing To Save Energy
A high-performance roof can be a powerful asset in reducing energy consumption by becoming an energy efficient roof. When used with appropriate insulation on low-sloped or flat roofs, a high-emissivity High IQ Roofing roof system can:

Want to know how much recycled content to look for in your new roof? Check out this US Environmental Protection Agency (EPA) guide to recovered materials content for roofing. |
| Every year, an estimated 9 million tons (8 million metric tons) to 10 million tons (9 million metric tons) of asphalt roofing waste are sent to U.S. landfills with a price tag of more than $400 million in disposal fees. But most waste from roofing shingles and roll goods can be economically and effectively recycled into asphalt pavement for roads and highways. |

The EPA’s ENERGY STAR® Roof Products Program has established a minimum standard that requires low-slope reflective roof products to have an initial reflectance of at least 65 percent, and a reflectance of at least 50 percent after three years of weathering. If there is any doubt about whether a roofing system is “High IQ ” or energy efficient roof, check to see if it is listed in the ENERGY STAR Roof Products listings – www.energystar.gov. Use their online calculator to determine potential energy savings for your building. |

A popular definition for sustainable roofing was developed during a workshop held at the Oak Ridge National Laboratory (ORNL) in 1996: A roof system that is designed, constructed, maintained, rehabilitated and demolished with an emphasis throughout its life cycle on using natural resources efficiently and preserving the global environment. |

In terms of High-Performance Roofing, endurance is the ultimate reflection of the performance of every roofing component in terms of reliability, water absorption, wind and fire resistance, maintenance, and repair. No matter how “High IQ” or “green” a roof is, it still has to protect the building – for years – in all types of weather – a reality that is sometimes neglected in sustainability discussions. |

While some types of roofing may have lower initial costs, the true costs of a roofing system are measured over its total life cycle. These include maintenance and repair costs, energy savings, and tear-off and disposal costs. Clearly, economics is a very important criterion for building owners, and High-Performance Roofing systems must be economical if they are to become viable, real-world options. |
