Cedar Breather® Ventilated Underlayment

Are you looking for a top-tier underlayment for wood and metal roofing systems? You’ve found it. Our Cedar Breather® product is known for protecting the beauty and life of wood roofing by providing a space for continuous airflow between the solid roof deck and shingles or shakes. It is also a great solution to providing an airflow space under metal roofs.

For optimum performance, use Cedar Breather® with Rapid Ridge® 7 ridge vent. This underlayment is fire-resistant, easy to install, and helps get rid of any excess moisture.
