Cedar Breather® is the solution for preserving the beauty and life of wood roofing. As an underlayment for wood shingles and shakes, Cedar Breather provides space for a continuous airflow between the solid roof deck and the shingles. Benjamin Obdyke's patented three-dimensional design allows the entire underside of the shingle to dry, eliminating excess moisture, preventing thermal cupping and warping, and reducing potential rotting.
