Asphalt Shingle Roofing in the San Juan Islands

Architectural shingles — the value choice, installed to last here.

Asphalt Shingle Roofing in the San Juan Islands, Washington

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

Typical island range
