Seattle Roofing Contractors — Craftsman Bungalow, Moss & Landmarks-Approved Specialists

About Roofing in Seattle

Seattle roofs live in one of the most distinctive climates in North America. Annual rainfall is roughly 37 inches, but it arrives slowly: 150 wet days a year, October through May, mostly as persistent drizzle rather than hard storm events. The Puget Sound Convergence Zone parks heavier bands over north Seattle — Shoreline, Broadview, Crown Hill — and occasional atmospheric-river ‘Pineapple Express’ events dump 2 to 3 inches in a single day. Summers are cool and dry but rarely warm enough to kill off accumulated moss. Snow is rare but heavy when it does arrive, and the Seattle Fault and broader Cascadia subduction zone add seismic roof-diaphragm requirements you won’t find most places. A Seattle roof has to handle persistent moisture, moss, algae, occasional heavy snow load, and seismic movement — all without failing at the flashing details.

Roofing Quote Today defaults to PNW-ready assemblies across every Seattle neighborhood. Architectural asphalt shingles with algae-resistant granules, zinc or copper moss-inhibitor strips, and a 6-nail high-wind fastening pattern handle most of our Craftsman bungalow and mid-century tear-offs in Wallingford, Ravenna, Wedgwood, Maple Leaf, Green Lake, Columbia City, Seward Park, and West Seattle. Composite slate (DaVinci, CertainTeed Grand Manor) is our go-to on Victorian and Tudor Revival homes in Capitol Hill, Queen Anne, Montlake, Madrona, Laurelhurst, and Madison Park — 50-year life, Class A fire rating, and a historically correct profile. Standing-seam metal handles steep modern infill across Ballard, Fremont, and upscale remodels. We replace every untreated cedar shake roof with a Class B fire-compliant assembly, and install fully-adhered TPO or PVC on flat condos in Belltown, South Lake Union, Pioneer Square, and the Central District. All work is permitted through Seattle Department of Construction and Inspections (SDCI), with Landmarks Preservation Board review on designated properties and historic districts.

We work every Seattle neighborhood — from the Craftsman bungalows of Wallingford, Ravenna, U-District, Wedgwood, Maple Leaf, Columbia City, and West Seattle, to the Victorians of Capitol Hill and Queen Anne, the Tudor Revivals of Madrona, Leschi, Laurelhurst, Madison Park, and Mount Baker, and the mid-century ranches of Magnolia, Seward Park, and North Beach. Fremont, Ballard, Greenwood, Phinney Ridge, Loyal Heights, and Crown Hill clients trust us with modern re-roofs; Belltown, South Lake Union, First Hill, and Pioneer Square condo owners call us for TPO and low-slope work. We serve the Central District, Leschi, Mount Baker, Beacon Hill, Georgetown, SODO, Rainier Valley, and every West Seattle pocket — Alki, Admiral, Fauntleroy, High Point, Delridge — plus Shoreline, Lake Forest Park, Kenmore, Edmonds, Mountlake Terrace, Burien, Tukwila, and Mercer Island on request.

What to Look for in a Seattle Roofing Contractor

Hiring the right roofer in Seattle means checking more than just price. Here are three things every Seattle homeowner should verify before signing a contract:

1. Verify the roofer holds an active Washington State L&I contractor license
2. Ask about LPB (Landmarks Preservation Board) compliance if your home is in a historic district
3. Confirm experience with moss-prevention zinc strips and proper PNW ventilation design

Seattle Roofing FAQs

Why does my Seattle roof always grow moss?

Because the climate is perfect for it: cool, shaded, and wet for eight months a year. Moss holds moisture against the shingle mat, lifts tabs, and dramatically accelerates granule loss. The best long-term fix is a zinc or copper ridge strip installed on your next re-roof — every rain carries a trace of zinc down the slope that inhibits spore growth. For existing moss, we brush (never pressure-wash, which strips granules), treat with a sodium-based moss killer, and retrofit zinc strips. Done properly, it adds 5–10 years to an asphalt roof.

Do I need Landmarks approval to re-roof my Seattle historic home?

Only if your property is an individually designated landmark or falls inside one of the city’s eight historic districts (Pike Place Market, Pioneer Square, Ballard Avenue, Columbia City, Harvard-Belmont, Fort Lawton, and others). In those cases, the Landmarks Preservation Board reviews material, color, and profile before SDCI will issue the permit. In-kind replacement and historically correct composite slate typically pass easily; dramatic changes do not. We handle the Certificate of Approval application and appear at the board hearing.

Can I still put cedar shake on my Craftsman bungalow in Seattle?

Only as a Class B fire-treated assembly: pressure-impregnated fire-retardant-treated shingles over an approved underlayment, with fire-blocking at every penetration. The insurance premium and code complexity usually push homeowners toward either a premium architectural asphalt with a wood-grain profile or composite synthetic shake. Both preserve the Craftsman look without the fire-code penalties, and typically improve the roof’s performance in PNW rain.
