Thompson Roofing Service | Roofing Services in Seattle, WA 98117

Black streaks are often algae, common in our damp climate, and granule loss is a sign of aging shingles. We recommend a professional roof inspection to assess the extent of the wear. For granule loss, we can perform targeted roof repairs or, if widespread, discuss reroofing options with more durable, algae-resistant materials to better withstand Seattle's weather and protect your home's structure.

Properly functioning gutters are your first line of defense. In Seattle, clogged or damaged gutters can cause water to overflow and pool near your roof's edges and chimney base, exacerbating flashing leaks. Our gutter cleaning, repair, and installation services ensure water is channeled safely away. During a gutter service, we also inspect the adjacent roof and flashing, often identifying the leak's source so it can be repaired promptly, preventing interior water damage.

Seattle's heavy fall and winter rains make attic inspections critical. We check for signs of past or active leaks, proper ventilation, and insulation. Poor ventilation can trap warm, moist air, leading to mold and wood rot, while inadequate insulation can cause ice dams in colder snaps. Identifying these issues early allows for necessary roof or vent repairs, ensuring your attic and roof are prepared to handle our wet season and improve your home's overall energy efficiency.
