Roofing in Shoreline, WA

Roof replacement, repair, inspection and moss removal for Shoreline homes — with 14+ years of experience on Washington roofs behind every job.

Shoreline is one of the most consistently built cities in the region: a large share of it went up in the 1950s and 1960s as single-story ramblers on generous lots, and the mature tree canopy that came with those lots is now full grown.

Consistent housing stock means consistent roofing problems, and in Shoreline the dominant one is shade.

What Shoreline roofs deal with

  • Deep shade, heavy moss

    Shoreline's canopy is one of the densest in north King County. Roofs here can stay damp for weeks at a stretch in winter, and moss growth is the single biggest factor shortening roof life in this city.

  • Low-pitch ramblers

    The classic Shoreline rambler has a shallow roof pitch. Shallow pitches shed water more slowly, hold debris longer, and are far less forgiving of a flashing detail that was done casually.

  • Long single runs of gutter

    Wide, low houses mean long uninterrupted gutter runs. They sag in the middle as they age, and a sagging run holds standing water even when it is perfectly clean.

What we do in Shoreline

  • Roof Replacement

    A complete new roof when repairs stop being worth it — tear-off, deck inspection, and installation done to manufacturer spec.

  • Roof Repair

    Leaks, wind damage, failed flashing, and missing shingles — fixed properly, so the same spot does not come back next winter.

  • Roof Inspection

    A documented look at the real condition of your roof — for maintenance, a home sale, an insurance claim, or your own peace of mind.

  • Roof Cleaning

    Moss, algae, and organic buildup removed without destroying the shingle — the single highest-value maintenance job in this climate.

  • Gutter Cleaning

    Gutters and downspouts cleared so water leaves the roof and the foundation the way it was designed to.

  • Gutter Replacement

    New gutters and downspouts, sized and pitched so the system actually moves the water your roof sheds.
