NOTE: Recommended on a 3/12 roof slope or greater
Install plywood deck onto roof rafters.
Install 30 lb. roofing felt over entire roof deck. Felt should extend 1/4" beyond edge of roof deck. Overlap layers at least 4" working toward the ridge.
Tack down Cedar Breather. One tack (or nail) approximately every 3 square feet is adequate. Install with dimples down to present the flat side as the nailing surface. Do not lap layers of Cedar Breather. Each course should butt against previous course. Work from fascia to ridge while installing shingles to avoid walking directly on Cedar Breather (may be slippery, especially when wet).
Install cedar shingles per manufacturer’s instructions. Utilize a nail length that will allow for 3/4" penetration into sheathing. Allow 1/4" for Cedar Breather thickness.
