Question 1

How much does a new roof cost in the San Juan Islands?

Accepted Answer

For a typical island home, plan on about $9,000–$24,000 for architectural asphalt shingles, $14,000–$45,000+ for standing-seam metal, and $18,000–$50,000+ for cedar. Island prices run higher than the mainland. That’s because of ferry travel, barging materials, hauling the old roof off-island, and sometimes crew lodging. The real number comes from a free on-island inspection. Roof size, pitch, material, and access all change it.

Question 2

Why are island roofing quotes higher than a mainland roofer?

Accepted Answer

Three island facts drive it up: (1) ferry reservations and travel time for crew and trucks, (2) barging or ferrying tons of material and hauling the old roof off-island to dump it, and (3) sometimes an overnight stay when the ferry won’t allow a same-day return. An honest island quote prices all of that up front. A mainland roofer who “forgets” it either cuts corners or hits you with extra charges mid-job.

Question 3

How much does it cost to remove moss and clean a roof?

Accepted Answer

Most island roof cleanings run $400–$1,600. The price depends on roof size, pitch, how heavy the moss is, and access. That usually covers low-pressure cleaning, moss treatment, clearing the gutters, and adding zinc or copper ridge strips to slow regrowth. It costs far less than fixing the deck rot that untreated moss causes on our shaded roofs.

Question 4

Do you offer free roof inspections and estimates?

Accepted Answer

Yes. On-island roof inspections and written estimates are free, even on the outer islands. Detailed real-estate or pre-purchase inspection reports — with photos and paperwork for a sale — are a flat fee. Call (360) 205-1462 to set one up.
