  • Snow load: 22 psf (ground) (Lynnwood). 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 (Snohomish County). Panel fastening and clip spacing follow the panel maker's tables for the wind speed.
  • No ice barrier required by the local table (Snohomish County). Many roofers still run it at eaves and valleys; the roof notes on your plans decide.

Questions

Metal roofing takeoffs in South Snohomish County

Do you do metal roofing takeoffs for houses in Lynnwood?

Yes. Upload the plan set for a house anywhere in south Snohomish County (Lynnwood, Edmonds, Mill Creek, Mukilteo, Bothell and Mountlake Terrace), or anywhere else. Nothing has to be built yet: we measure the house on the plans.

What design numbers apply in Lynnwood?

Lynnwood publishes snow load: 22 psf (ground); design wind speed: 98 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 South Snohomish 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: rot 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.
