Yes, when Google Solar has matching roof data for your property. Enter your full Washington address and ZIP to check roof area and see a planning range without entering contact details. If coverage is unavailable, use known roof-surface area from plans or a professional measurement.
Use roof-surface area rather than floor area when entering a measurement.
Confirm the measurement, condition and scope with a roofer before accepting a proposal.
The current model includes field roofing with material waste, installation labor, and explicit accessory, one-layer removal and business overhead/profit allowances. It is a modeled planning range, not a contractor quote or a surveyed city average. Tax, permits, hidden repairs and difficult access are excluded.
Separate the displayed allowances from a contractor’s actual products and quantities.
Ask the contractor to identify exclusions and the process for approving added work.
One roofing square is 100 square feet of roof surface, so a 2,000-square-foot roof is 20 squares. Material ordering waste is calculated separately; floor or lot area is not a roof measurement. (Roofr — 2026 roofing-square guide)
Keep measured roof area and ordering waste as separate numbers.
Compare proposals using the same roof-surface measurement.
The actual roof system, slope, height, access, existing layers, damaged decking, permits and tax can change the written proposal. Confirm quantities, included work and change-order terms with the roofer before accepting a price.
Record what the proposal includes and excludes before comparing totals.
Agree how concealed repairs and additional work will be documented and approved.
Each contractor sets its own products, operations, labor, overhead, profit, scope, final prices and contract terms. Our versioned planning model helps organize your budget and questions; it does not prescribe or guarantee a roofer’s offer.
Request a written proposal from the contractor who would perform the work.
Confirm scope, price and schedule directly before agreeing to work.
Your project details and estimate context are saved for review, with a receipt confirming the request. Contractor selection, inspection and scheduling are separate steps.
Requests are held for review rather than automatically forwarded.
A request does not establish availability, book a visit or form a construction contract; any work needs a separate agreement.
Does roof replacement need a permit in Washington?
The permit answer depends on the jobsite authority, building type and exact roof work. The confirmed county examples below have different scope conditions; none establishes a statewide exemption.
In unincorporated King County, replacement roofing on detached one- or two-family houses does not need a County building permit unless critical-area conditions apply. This does not determine city permits. (King County — Do you need a permit?)
Pierce County’s reroof exemption is limited by building scope, slope and covering load, and excludes roof-sheathing replacement and vegetated roofs; confirm County jurisdiction. (Pierce County — Work Exempt from Permit Guide, pp. 1–3)
Thurston County lists roof repair/replacement without a County building permit, but added skylights, structural-element work, pitch/slope changes and enlargement require one. Other approvals can still apply. (Thurston County — Do you need a permit?)
Group R Division 3 one- and two-family dwellings and Group U private garages/carports/accessory structures; excludes sheathing replacement and vegetated roofs.
WAC 51-51-01010 / IRC R101.2 covers detached one- and two-family dwellings and qualifying townhouses no more than three stories with separate means of egress, plus qualifying accessory structures and listed exceptions. (WAC 51-51-01010 / IRC R101.2 — residential scope)
Confirm the building type, work scope and local authority before using residential guidance; recheck the live WAC for any later edition change.
