Do this now: a roof leak in Seattle

1. Stay off the roof. Wet or mossy roofing is no place for a ladder; let the roofer judge it.
2. Move furniture and electronics, and catch drips with buckets and towels.
3. Water near a light fixture or outlet: shut off that breaker only from a dry spot.
4. Photograph the stain, the attic if you can reach it safely, and any debris in the yard.
5. Ask about a tarp if rain is forecast; Angi puts a professional tarp at $450 on average.

Is it urgent? Seattle's rain and when a leak cannot wait

A leak during Seattle's wet season is urgent because the rain rarely stops for long: Sea-Tac averages 93.4 days a year with measurable rain and 39.34 inches of precipitation, NOAA's 1991 to 2020 normals show. Call now for water coming through a ceiling, a sagging ceiling or a hole after a windstorm. A few loose shingles on a dry week can wait for a scheduled visit; Fixr says a same-day or next-day visit adds $100 to $300. See emergency roof repair and roof leak repair.

Do you need a permit for roof repair in Seattle?

Usually not for a straight repair on a house. Seattle's Department of Construction and Inspections says detached one- and two-family houses need no permit to repair the roof as long as you are not changing the building envelope and the work is as good as the existing structure, and no permit to replace existing roof sheathing. Minor repairs or alterations of $6,000 or less in any 6-month period are exempt, valued at fair market labor and parts even if you do the work yourself. Work on load-bearing supports or changes to the building envelope always need a permit. SDCI's line is (206) 684-8600.

Roofing contractors in Seattle: L&I registration and bonds

Washington has no roofing license; roofing contractors register with the Department of Labor and Industries as specialty or general contractors. Registered contractors must carry a bond, $15,000 for a specialty contractor or $30,000 for a general contractor, plus liability insurance, L&I says. Its Verify tool shows the registration, bond lawsuits and safety citations, so check before you sign. Compare other states on roofing license by state.

Roof replacement in Seattle: $8,045 to $17,399

Roof replacement in Seattle costs $8,045 to $17,399 for most homes, with a $12,646 average, Angi's August 2026 Seattle guide shows. Angi says the average Seattle roof is about 1,800 square feet, lists asphalt shingles at $3 to $11 a square foot, metal at $5 to $22 and slate at $10 to $30, and says Seattle's wet weather can age roofs quickly, with heavy moss among the signs a roof needs replacing. Rotten sheathing adds $2 to $7 a square foot, and SDCI says replacing existing sheathing on a detached house needs no permit. National figures are on roof replacement cost; Angi says to replace when repairs reach 50% or more of a new roof's cost.

Help paying for roof repair in Seattle

The Seattle Office of Housing's Home Repair Loans and Grants program covers roofs, with 0% loans starting at $3,000, some deferred, and grants for owners who do not qualify for a loan; assistance is listed up to $24,000. Income must be below 80% of area median, the home owner-occupied and inside Seattle, and there is a waitlist, so it does not handle urgent repairs. Call (206) 684-0244. Seattle's median home was built in 1976, and 22.8% of units date to 1939 or earlier, Census counts show.

Questions to ask a Seattle roofer

1. What is your L&I registration number, and is your bond current?
2. Does this repair change the building envelope or structure, so it needs a permit?
3. Is the moss on my roof damaging the shingles, and is repair or replacement the better buy?
4. Can you tarp today if rain is coming, and what does that cost?
5. Can I see proof of insurance and a written price before work starts?
