Asphalt Shingle Roofing on Orcas Island
Architectural shingles — the value choice, installed to last here. Serving Eastsound, Deer Harbor, Olga, Doe Bay, Orcas Landing.
San Juan Roofing Co. provides asphalt shingle roofing for homes across Orcas Island, from Eastsound, Deer Harbor, Olga, Doe Bay to Orcas Landing. Orcas’ tall firs mean heavy shade, needle debris, and stubborn north-slope moss. Eastsound to Doe Bay, we keep island roofs dry and moss-free.
Architectural asphalt shingles remain the most popular roof in San Juan County for good reason: strong value, dozens of colors, and — installed correctly — a 25 to 30 year service life even in our climate.
Why asphalt shingle roofing matters on Orcas Island
Steep terrain and dense tree cover on Orcas drive moss growth and gutter debris — maintenance plans pay off here. Standard 3-tab shingles fail early in our moss and wind. We install algae-resistant architectural shingles with the ventilation our humidity demands.
What our Orcas Island asphalt shingle roofing includes
- Algae-resistant architectural shingles
- Full manufacturer system for max warranty coverage
- Balanced intake/exhaust ventilation for a damp climate
- Ice-and-water shield at valleys & eaves
- Wide color selection to match island aesthetics

Real Orcas Island roofing questions
“There's thick moss creeping up the north-facing slope of my roof under the firs in Eastsound. Is it too late to treat it, or do I need to replace the shingles?”
Moss itself rarely means instant replacement — the question is what's under it. We'll do a low-pressure clean and treatment (never a pressure washer, which strips granules), check the shingles and deck for soft spots, and install copper or zinc ridge strips so it doesn't come back. If we find rot underneath, we'll show you exactly where.
“The ferry's booked solid heading into August. How does that affect getting my re-roof done, and how far out are you scheduling on Orcas?”
We plan around exactly that. We stage materials by the load so the crew isn't idle waiting on a sailing, and we hold ferry reservations for crew and trucks in advance. Summer books up, so the move is to lock a free inspection now and get on the calendar. Call and we'll give you the current Orcas lead time.
“The low-slope roof over my addition keeps pooling water and leaking at the seams. What system should go on a flat roof out here?”
Pooling plus seam leaks usually means the wrong system or bad slope detailing. For island low-slope we install torch-down (modified bitumen) or heat-welded TPO/PVC single-ply, and we correct the slope-to-drain so water actually leaves the roof. Fully welded seams are the key — that's where flat roofs fail in our wet winters.
“We collect rainwater for the house. Is a metal roof safe for a catchment system, and which coating won't contaminate our water?”
Metal is actually one of the best catchment surfaces — smooth, sheds cleanly, and doesn't shed granules like asphalt. We use coatings appropriate for catchment and detail the gutters and first-flush so your collected water stays clean. We'll match the panel and finish to your catchment setup.
“A limb came down last night and punched a hole in my roof — it's raining into the house. How soon can someone get here?”
That's an emergency and we treat it like one. We prioritize getting a tarp and temporary weatherproofing on to stop the water first, then schedule the permanent repair and document the damage for your insurance. Being on-island, we can usually move faster than a mainland crew stuck waiting on a ferry. Call (360) 205-1462 now.
