What kind of roofing can I use?

  • SIP homes require no special roofing materials. Fiberglass, asphalt, wood and metal are all suitable, but check the manufacturer's warranty before you buy fiberglass or asphalt shingles. Some shingle manufacturers have been hesitant about warranting their product when applied to un-vented roof systems, claiming that un-vented roofs could produce high shingle temperatures and thereby reducing shingle life. However, recent studies at the University of Illinois and the Florida Solar Energy Center concluded that roof ventilation has little or no effect on shingle or sheathing temperature (Energy Design Update, Nov. 1990). This has not produced an overnight change in all shingle makers' warranties, but shop around. There are several shingle manufacturers that offer full warranties on both vented and un-vented roofs.
     
  • Asphalt shingles must meet ASTM D3462, the Specification for Asphalt Shingles Made fro Glass Felt and Surfaced with Mineral Granules. Or ASTM D225, the Specification for Asphalt Shingles (Organic Felt) Surfaced with Mineral Granules. Asphalt Saturated Felt Paper must meet ASTM D226.
