CedAir-Mat® is a ventilation mat used in cedar roof construction. The 90% open mesh creates an airspace/cavity that is perfect for promoting air flow in all directions between the metal panels and sheathing.
The subtitles within the video allude to our R-Vent® product, however this video demonstrates the proper installation techniques for our CedAir-Mat® product.
Install plywood roof sheathing onto rafters. Install roofing felt or ice dam protection membrane over sheathing. Check local codes and manufacturer’s recommendations for specific requirements.
Install CedAir-Mat® over roofing felt, ice protection membrane, and metal edge flashing or drip edge. Ensure CedAir-Mat® material is installed flush against edge of the flashing or drip edge. Carefully trim the CedAir-Mat® material at all penetrations with a utility knife or scissors.
When installing cedar or alternate material shingles, unroll CedAir-Mat® horizontally just ahead of the shingles as they are installed. Tack or nail CedAir-Mat® in place every three square feet. Do not overlap the CedAir-Mat® material. Butt each course tightly against the previous course and at vertical seams.
At ridge locations, extend CedAir-Mat® material over the ridge and butt against the material on the opposite side of the roof. If a ridge vent is utilized, follow the ridge vent manufacturer’s recommendations for underlayment material installation.
Apply roofing materials using manufacturer’s recommended fasteners and instructions, allowing for the additional 3/8″ thickness of the CedAir-Mat® material.
