Island County (unincorporated Whidbey and Camano Islands)20 psf (ground)97 mphNo
  • Snow load: 20 psf (ground) (Island County (unincorporated Whidbey and Camano Islands)). The trusses, rafters and roof sheathing on your plans are designed for the snow load; if the truss notes show a different number, ask before you bid.
  • Design wind speed: 97 mph (Island County (unincorporated Whidbey and Camano Islands)). Shingles go on with the maker's nailing for the wind speed, and high-wind nailing changes the nail count.
  • No ice barrier required by the local table (Island County (unincorporated Whidbey and Camano Islands)). Many roofers still run it at eaves and valleys; the roof notes on your plans decide.

Sources: Island County (unincorporated Whidbey and Camano Islands): Island County. Read 2026-09-28. Every number is as the jurisdiction publishes it (its design criteria for houses, IRC Table R301.2(1)); a dash means it isn't published. Your lot can differ with elevation and exposure, so confirm it with the building department before you order.

Questions

Do you do shingle roofing takeoffs for houses in Oak Harbor?

Yes. Upload the plan set for a house anywhere in Whidbey and Camano Islands (Oak Harbor, Coupeville, Langley, Freeland, Clinton and Camano Island), or anywhere else. Nothing has to be built yet: we measure the house on the plans.

What design numbers apply in Island County (unincorporated Whidbey and Camano Islands)?

Island County (unincorporated Whidbey and Camano Islands) publishes snow load: 20 psf (ground); design wind speed: 97 mph; ice barrier required: no. The design on your plans should match them, and the takeoff follows your plans. Elevation and exposure can change them for your lot, so confirm with the building department.

Does a takeoff cost more in Whidbey & Camano?

No. The price is the same everywhere, and you see it before you pay. The 3D model is included, and each trade after the first in the same order is half price.

Is this an exact price?

No. It's an estimate built from your plans. Plans don't show the roof as it really is: rotten decking or old layers under a re-roof, or crickets and saddles that aren't drawn. Anything built differently from the drawings won't be in the bid. We recommend a site visit to confirm measurements and conditions before you sign a contract or order materials.
