Roof Decking Replacement

What This Service Involves

The decking is the wooden platform every shingle relies on, and it is the first structural layer our persistent Northwest moisture attacks once a leak begins. Water-saturated plywood delaminates and OSB crumbles, leaving a spongy surface that cannot hold fasteners or support a watertight roof. Our crews remove the failed sheathing, inspect the rafters beneath, and install new decking that meets current standards. Sound decking is the non-negotiable foundation for any lasting repair or new roof in our climate.

Benefits

Our Process

1) Remove roofing to expose the damaged decking; 2) Cut out delaminated and rotted sheathing; 3) Inspect the rafters for related damage; 4) Install new decking and reinstall the roof covering

What Affects the Cost

Square footage of decking replaced; Thickness and grade of new sheathing; Condition of the rafters beneath; Extent of roofing that must be removed; Roof pitch and access

Best Time of Year

Decking replacement is best performed in dry weather so the new sheathing stays dry until the roof is closed in.
