Roof Sagging Repair

What This Service Involves

A visible dip in a Northwest roofline usually points to a real structural issue, whether overloaded framing, failed sheathing, or rot from years of trapped moisture. Our persistent rain feeds decking rot that gradually softens the deck until it bows between rafters. Our crews investigate the cause, reinforce or replace the affected framing and sheathing, and restore a true, load-bearing plane. Correcting a sag protects both the roof covering above and the living space below.

Benefits

Diagnoses the true cause of the sag; Reinforces or replaces weakened framing; Replaces rot-softened decking; Restores a straight, load-bearing roof plane; Protects both roofing and interior below

Our Process

1) Inspect the attic and deck to find the cause; 2) Reinforce or replace compromised framing; 3) Replace sagging or rotted sheathing; 4) Reinstall roofing over a corrected, true surface

What Affects the Cost

Underlying structural cause of the sag; Amount of framing and decking affected; Extent of moisture-related rot; Complexity of shoring and reinforcement; Roof size and access

Best Time of Year

Structural sagging should be addressed as soon as it is noticed, and dry weather allows the safest access for framing work.
