Roof Flashing Repair

What This Service Involves

Flashing is the thin metal that seals the joints where your roof meets walls, chimneys, skylights, and valleys, and in our maritime climate it is usually the first thing to fail long before the shingles wear out. Constant moisture, freeze-thaw cycles in the foothills, and moss creeping under the metal all loosen the seal and let water track into the sheathing. Our crews pull back the surrounding roofing, assess whether the failure is corrosion, a lifted edge, or old caulk that has gone brittle, and rebuild the connection with properly lapped metal and sealant rated for wet-weather adhesion. Because leaks in Western Washington often show up on a ceiling far from the actual entry point, we trace the water path before we commit to a fix.

Benefits

Stops active leaks at the most common failure point on Northwest roofs; Prevents hidden rot in sheathing and framing from prolonged moisture; Restores manufacturer-intended water shedding without a full reroof; Addresses moss and debris that trap water against the flashing; Extends the service life of your existing roof at a fraction of replacement cost

Our Process

1) Inspect all roof-to-wall and penetration joints and trace the leak to its true source; 2) Remove damaged flashing, failed sealant, and any surrounding compromised roofing; 3) Install correctly lapped replacement flashing bedded in wet-adhesion sealant; 4) Reseat the surrounding shingles or membrane and water-test the repair

What Affects the Cost

Extent and location of the failed flashing runs; Accessibility and pitch of the affected roof section; Whether hidden sheathing rot is discovered once metal is removed; Type of flashing metal being matched, from galvanized to copper; Amount of moss or debris removal required before repair

Best Time of Year

Repairs are best scheduled in late spring through early fall when drier stretches let sealant cure fully before the wet season returns.
