What's priced: Full tear-off and replacement on a typical 2,000 sq ft home, asphalt shingles through mid-range materials, installed. Excludes permits, structural repairs found mid-job, and premium upgrades.
Why Seattle is more expensive than average
Almost entirely labor. Roofers in the Seattle-Tacoma-Bellevue, WA area earn about 26% more than the national mean for the same occupation, per Bureau of Labor Statistics wage data. Because roof replacement is roughly 60% labor, that difference flows straight into the total.
Roofing is the most labor-heavy of these projects. Tear-off, disposal, and installation dominate the bill, and asphalt shingles themselves are comparatively cheap — which is why roofing prices vary more between metros than almost any other home project.

Issuing authority: Seattle Department of Construction and Inspections (SDCI)
Seattle's Department of Construction and Inspections (SDCI) doesn't require a permit for a detached one- or two-family home to replace roof sheathing or repair the roof, as long as the work doesn't change the building envelope and restores it to as good as the existing structure. A tear-off and replacement that stays within the existing roofline and doesn't alter the envelope can qualify under that exemption, which can save both time and a fee.
SDCI's published fee schedule does price a commercial re-roofing permit at half of the standard base fee, but that rate applies to commercial buildings, not a single-family home project like this one. Ask SDCI directly whether your specific scope — materials, framing changes, or otherwise — keeps you inside the no-permit exemption before you start, since crossing that line changes the paperwork your roofer needs to file. A roofer who works regularly in the city should be able to tell you which side of that line your job falls on.

Both are Snohomish County cities inside the Seattle-Tacoma-Bellevue metropolitan area, which is the area BLS prices, so the labor figures on this page are their figures. There is no separate Seattle suburb estimate to look up: those communities are priced by the same roofers wage data as the figures above, so a roof replacement there typically runs $17,745, with most projects between $6,589 and $28,900.
Metropolitan-area membership follows the area definitions BLS publishes its OEWS metro estimates against — May 2025 reference period. What genuinely varies inside a metro is the individual property, not the labor market: roof pitch, access, and how much has to come off before anything goes on. Price your own job.

Compare roof replacement cost across every US metro we cover — the same labor-adjusted model as this page, ranked from most to least expensive, if you want the national picture rather than Seattle alone.
How we calculate this
We take a national installed-cost range, split it into labor and materials, and scale only the labor half by this metro's actual wage data. That is the whole model — no black box, and reproducible from the figures on this page.
- National range: $5,700–$25,000, from our roof replacement cost data (last verified 2026-07-13).
- Labor share: 60%. An industry rule of thumb, not a measured value — the softest assumption here, which is why we state it rather than bury it.
- Metro labor factor: ×1.26, being the mean annual wage for Roofers in Seattle-Tacoma-Bellevue, WA divided by the national mean for the same occupation.
- Materials: held at the national level. We vary labor by metro and hold materials at the national level. That is deliberate: shingles, copper, HVAC equipment, and cabinets are nationally traded and priced, and what actually varies locally is freight and sales tax — both small next to the labor spread. We have no metro-level materials index we can defend, so rather than invent one, we vary only what we can source.

Frequently asked questions
How much does it cost to replace a roof in Seattle, WA?+
A typical project in the Seattle-Tacoma-Bellevue, WA area runs about $17,745, with most falling between $6,589 and $28,900. Of the typical figure, roughly $11,605 is labor and $6,140 is materials. That puts Seattle about 16% above the national typical cost of $15,350.
Why is it more expensive to replace a roof in Seattle, WA than the national average?+
Almost entirely labor. Roofers in the Seattle-Tacoma-Bellevue, WA area earn about 26% more than the national average for the same occupation, according to Bureau of Labor Statistics wage data. Because roof replacement is roughly 60% labor, that wage difference flows through to the total. Materials are priced nationally and barely move between metros.
What's included in these Seattle, WA estimates?+
Installed cost — materials plus labor for a standard project of this type. It does not include permits, which vary by municipality, structural repairs discovered mid-job, or premium upgrades. The range reflects genuine variation in scope and material grade, not uncertainty about the metro. Always get at least three local quotes before budgeting; a real quote for your specific property will beat any estimate, including ours.
How is this different from a national average with the city name swapped in?+
We split the national installed cost into labor and materials, then scale only the labor half using the actual mean wage for Roofers in this specific metro area, published by the Bureau of Labor Statistics. Materials stay at the national level because we have no defensible metro-level materials index — shingles and HVAC equipment are nationally traded, and only freight and sales tax really vary. Where BLS suppresses wage data for a metro, we do not publish a page for it at all rather than fill the gap with a guess.
