  • Snow load: 20 psf (ground) (Bellingham). 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: 110 mph (Whatcom County). 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 (Whatcom County). Many roofers still run it at eaves and valleys; the roof notes on your plans decide.

Your lot can differ with elevation and exposure, so confirm it with the building department before you order.

Questions

Shingle roofing takeoffs in Whatcom County

Do you do shingle roofing takeoffs for houses in Bellingham?

Yes. Upload the plan set for a house anywhere in Whatcom County (Bellingham, Ferndale, Lynden, Blaine, Everson and Sumas), or anywhere else. Nothing has to be built yet: we measure the house on the plans.

What design numbers apply in Bellingham?

Bellingham publishes snow load: 20 psf (ground); design wind speed: 110 mph. 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 Whatcom County?

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.
