Flat & Low-Slope Roofing on Shaw Island, San Juan Islands

San Juan Roofing Co. provides flat & low-slope roofing for homes across Shaw Island, from Shaw Landing to Blind Bay. Small, quiet, and ferry-limited — Shaw jobs take planning. We batch material and crew logistics so your roof gets done in one efficient mobilization.

Flat and low-slope roofs — over additions, garages, decks, and modern island homes — need a very different system than a pitched roof. Get it wrong and water pools, then finds every seam.

Why flat & low-slope roofing matters on Shaw Island

Limited ferry service to Shaw means we stage materials carefully — one trip, done right. Low-slope roofs punish sloppy seams in our wet winters. We weld and detail them to shed water, not trap it.

What our Shaw Island flat & low-slope roofing includes

  • Torch-down (modified bitumen), TPO, PVC & EPDM rubber membranes
  • Rubber & rolled roofing for garages, decks & outbuildings
  • Proper slope-to-drain detailing
  • Fully welded/adhered seams — no water paths
  • Wall-transition & penetration flashing done right
