Cedar Breather preserves the beauty and prolongs the life of wood siding and roofing. This underlayment for wood shingles and shakes is fire-resistant and creates a space for continuous airflow between roof and shingles. Benjamin Obdyke’s three-dimensional patented design allows the entire underside of the shingle to dry, eliminating excess moisture, preventing thermal cupping and warping and reducing potential rotting.
