CedAir-Mat® - Advanced Building Products

CedAir-Mat® is a roof ventilation mat designed to create an airspace to promote multi-directional airflow between wood 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 water damage including mold, mildew, or corrosion and deterioration of the roofing material itself. CedAir-Mat® is perfect for residential and commercial applications.

Installation

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.
