Roofing MaterialsLast Updated: 09/30/19
A building's roof system and its finished roofing materials shield a structure's interior from natural elements. Roofing systems generally fall into two general categories: 1) high-sloped or "pitched" roofs (residential) and 2) low-sloped or flat roofs (commercial). These two types of systems generally are constructed differently and use different materials, although some materials are used for both residential and commercial systems. EPA's designation specifically covers roofing materials containing steel, aluminum, fiber, rubber, plastic or plastic composites, and cement.
Federal agencies are required by statute to purchase products as designated or specified under this program.

Life Cycle Cost Savings
Life Cycle Costing (LCC) aims to quantify the financial impact of a product over its entire life cycle to assist consumers in making decisions that will save them money over the long term.
GSA's Proving Ground found an 8 - 10% energy savings for vacuum insulated roofing panels, compared to code-compliant roofs. Savings for R-50 panels can be greatest in single-story buildings in extreme climates, such as those found in Alaska (subartic) or Arizona (hot-humid). GPG recommends deploying vacuum insulated panels where R-50 is required and installing conventional insulation necessitates costly alterations.
