Roof Vapor Retarders
The proper installation of a vapor barrier in the roofing system safeguards against vapor migration and prevents vapor flow upward into the insulation. Americover offers roofing vapor retarders/barriers that can withstand extreme temperatures, and are highly puncture and tear resistant. Many of the vapor retarders and vapor barriers can be customized to reduce in-field seams or manufactured with fire retardant to meet building codes.
