None 39 in. X 61.5 ft. Roll Roof Ventilation Mat

CedAir-Mat is a roof ventilation mat designed to create an airspace/cavity to promote air flow in all directions between the roofing material and the sheathing below. Using a thin nylon matrix profile, CedAir-Mat prolongs the life of the roof structure and membrane by reducing the adverse effects associated with moisture/water damage including mold, mildew, corrosion and deterioration of the roofing material itself. CedAir-Mat is extremely flexible and conforms to any contoured surface or roofing material and is perfect for residential and commercial roof applications.
