Asphalt Shingle Roofing in the San Juan Islands
Architectural shingles — the value choice, installed to last here.
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.
The difference on the islands is the install details: algae-resistant shingles, proper attic ventilation to fight our humidity, and ice-and-water membrane in the valleys and at the eaves. We install manufacturer systems that qualify for the longest available 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 humidity demands.
What’s included
- 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
