Built for Pacific Northwest Conditions
Roof Repair in Seattle's Climate
37+ inches of annual rain, 150+ overcast days, salt-air drift off Puget Sound, freeze-thaw at higher elevations. Every roof repair project we deliver is spec'd for what Seattle actually throws at it.
37+ Inches of Annual Rain
Puget Sound's persistent rainfall exposes every flashing seam, valley, and pipe boot to constant water testing. Small failures become active interior leaks within a single storm season if not caught and resealed properly.
Moss & Algae on Shaded Roofs
Heavy tree canopy and damp air grow moss that lifts shingle edges and traps moisture against the decking. Repairs include moss removal, edge reseal, and zinc strip installation to prevent regrowth.
60-80 MPH Wind Gusts
Fall and winter windstorms lift shingles, tear flashing, and drop branches across King, Snohomish, and Pierce counties. We document wind damage in the format insurance adjusters require and tarp active leaks the same day.
Freeze-Thaw on Eastside Elevations
Higher elevations from Issaquah to Sammamish see overnight freezes that expand cracked sealant and split aging flashing. Spring repairs catch winter damage before the next wet season drives water deeper into the assembly.
