San Juan Islands roofing
Commercial Roofing in the San Juan Islands
Flat, membrane & metal roofing for island businesses and multi-unit buildings.
San Juan County businesses — shops in Friday Harbor and Eastsound, restaurants, offices, warehouses, and multi-unit buildings — need a roof that survives salt air, wind, and 40 inches of rain without shutting you down. We handle commercial and light-industrial roofing across the islands, from a single storefront to a low-slope building with rooftop HVAC.
Most island commercial roofs are low-slope. So we install and repair heat-welded TPO and PVC single-ply, EPDM rubber, and torch-down (modified bitumen) membranes — plus standing-seam metal where it fits. We shape the drainage, flash every curb and penetration, and can phase the work around your business hours. New roof, tear-off and replacement, restoration, coatings, or a leak repair — we quote it straight.
The island difference
A leaking commercial roof on the islands can’t wait on a mainland crew and a ferry. We’re island-based, so we respond fast and keep your doors open.
