  • Wall area = footprint perimeter × 19 ft grade-to-eave height; a 1.5:1 rectangle is assumed when only the perimeter is known.
  • 2 gable triangles estimated at a 6/12 pitch for the "gable" roof style.
  • Openings reduced at 75% of their area (trim and cuts eat part of the saving); waste factor 13%.
  • Rain-screen detailing is common practice west of the Cascades; city permits standard.

What drives siding cost in Washington

West of the Cascades, siding is a rain problem: standard practice is a rain-screen gap behind the cladding so the wall can dry, and skipping it is the regional shortcut that costs later. Cedar has deep local roots, but fiber cement now leads for durability in constant damp. Sun fade is minor; moss and moisture staining are not. Labor runs well above the national average — Seattle pricing rivals the coasts. East of the mountains, colder winters change the detailing.
