Cedar Breather® Ventilated Underlayment (39" x 61.5' Roll)

Protect Your Investment with Superior Airflow

Cedar Breather® is the industry-standard solution for preserving the beauty and structural integrity of wood roofing and siding. This specially engineered matrix creates a continuous airspace between your cedar shingles/shakes and the roof deck, eliminating the primary cause of premature wood rot: trapped moisture.

By providing a dedicated drainage plane and 360-degree ventilation, this underlayment ensures your cedar dries uniformly, preventing cupping, warping, and decay.

Key Features & Benefits

Maximum Ventilation: Creates a continuous space for air to circulate, allowing the underside of shingles to dry after rain or snow.

Pressure Equalization: Reduces the risk of wind-driven rain being "sucked" into the wall or roof assembly.

Easy Installation: The lightweight, flexible roll follows the contours of your roof and can be easily trimmed with a utility knife.

Invisible Protection: Provides a flat, even surface for shingle application without affecting the aesthetic lines of your home.

Multi-Purpose: Ideal for wood shingles, shakes, and even zinc or copper roofing applications.
