Roof Sheathing Replacement

What This Service Involves

Roof sheathing is the wood layer beneath your underlayment, and in our rain-soaked region it is often the first thing to suffer when a roof leaks or ventilates poorly. We remove sections of plywood or planking that have gone soft, spongy, or black with moisture and install fresh, properly gapped panels. Correct sheathing replacement also improves the deck's ability to breathe, reducing the condensation cycles that plague Northwest attics. This gives the new roofing a dependable, dry surface to seal against for the long haul.
