Asphalt Shingle Roofing in the San Juan Islands
Architectural shingles — the value choice, installed to last here.
Architectural asphalt shingles are the most popular roof in San Juan County, and for good reason. You get strong value, dozens of colors, and — installed right — a 25 to 30 year life even in our climate.
On the islands, the install details make the difference: algae-resistant shingles, good attic ventilation to fight our humidity, and ice-and-water membrane in the valleys and at the eaves. We install full manufacturer systems that qualify for the longest warranties.
The island difference
Standard 3-tab shingles fail early in our moss and wind. We install algae-resistant architectural shingles with the ventilation our humid climate needs.

- Algae-resistant architectural shingles
- Certified IKO, Owens Corning & CertainTeed installer — extended warranties
