How much does a new roof cost in Seattle?
An asphalt shingle roof replacement in Seattle has a median base price of about $10.59 per square foot, plus tax. Half of Seattle roofs fell between $9.28 and $11.93 per sq ft, and the median Seattle roof base price was about $17,800.
That's above the Seattle-area rate of $9.42 per sq ft. Seattle roofs are smaller, with a median of 1,686 sq ft, and smaller roofs cost more per foot.
The base is the roof itself: tear-off through new shingles. Add-ons, the steep-roof charge and the pack in / pack out charge are each priced on their own line.
We're roofing nerds, so we show the receipt. And before any of these numbers matter, we look at your roof. If you don't need a new roof, we say so.

How we get to your number
- Inspection first. Our free SmartMatch inspection starts with a call to (206) 487-4877. An estimator walks the roof and, where it's safe, the attic.
- Plain-English findings. You get repair vs replace vs monitor, which tests are optional, and the next step. If you don't need a new roof, we say so.
- Proposal with side-by-side options. Same roof, different products, such as Oakridge, Landmark or Duration, and Northgate. Base, add-ons, steep and pack charges each get their own line.
- Prices plus tax. Tax is added at the job city's rate. It's never folded into the bid.
- Permits: we pull them when the job needs one.
No invented urgency. RoofSmart has been roofing since 2011, with 500+ full replacements a year. Homeowners give us 4.9 on Google, 400+ reviews across platforms.
