That is the modeled cost to deliver plus a fair contractor margin, not a sales quote. Built from BLS metro wages, Craftsman labor hours, a real bill of materials, and hand-verified permit data. 2026-08-28
Mid-range here means the reroof most homeowners actually buy: full tear-off and asphalt shingle replacement on a typical single-family roof, disposal included, with up to two sheets (64 sq ft) of decking replacement in the base price. Additional decking prices per sheet. Metal, tile, and slate are the premium rungs of the same job.

Fair range. Break-even sits at the red line: the cost of delivering the job, not a price anyone should demand. The green band above it is fair territory: most solid bids land at a 15 to 22 percent margin on the bid, roughly 18 to 28 percent over the cost to deliver, leaner or richer by trade and market. That band is earned money. No one works for free, and if the job were easy you would not be hiring it out.

Asphalt Shingle Roof Replacement in Seattle costs more than most U.S. metros. At $16,570, you're paying 13.7% above the national average, though contractor margins here (22.6%) are in the moderate range. The higher price reflects regional labor costs, not excessive padding. Your negotiation strategy should focus on scope, not price-slashing.
Standard market dynamics. Seattle runs 22.6% margins with a normal spread from $14,448 to $18,855. You have about $2,122 in negotiating room. The most effective approach: check any bid against the numbers on this page, identify the line items sitting above the benchmark, and negotiate those specific items down toward the floor of $14,448.
When you book matters. The cheapest stretch to hire for roofing in Seattle is winter (December through February), when crews have gaps to fill and price closer to the $14,448 floor. Wait out the warm-weather stretch (April through October), when everyone calls at once and bids climb toward $18,855. The seasonal swing runs 5 to 12 percent, which is $829 to $1,988 on a job this size.
The gap between what Seattle homeowners typically pay and what the market can support is $2,122, a wide one for this trade. To put that in context: the floor price of $14,448 isn't a discount or a coupon. That number is the lowest defensible price, cost to deliver plus the thinnest margin a crew can live on. Anything above it is negotiating room, and most quotes for the same scope come in well past it.
Seattle sits in the upper half of our pricing index, more expensive than 29 of 39 tracked metros but cheaper than 9. This mid-to-upper position reflects moderate regional labor costs. The $2,122 gap between average and floor pricing is where your negotiating power lives.

Derivation for Seattle, Asphalt Shingle Roof Replacement · updated 2026-08-28
Step 1: Craftsman labor hours
BOM hours from Craftsman National Estimator: 71.75 hrs (typical project: 2500 sq ft)
Craftsman material cost × FRED PPI multiplier (1.0360): $5,056
Material costs pass straight through, with each book price inflation-adjusted by its own producer price series.
Step 5: Permit fee
Seattle: $0
No standalone permit line in the model for this scope in Seattle. Common exemptions cover cosmetic and finish work and in-kind replacement, but some cities charge separate flat-fee trade permits instead, so confirm with the local permit office. Source: our compiled city fee schedules.
NAHB benchmark: overhead is 21.2% of revenue, the way the NAHB Cost of Doing Business study measures it. Materials pass through at cost and carry no overhead.
overhead = ~21.2% of revenue (NAHB basis) = $3,516
The portion of the typical quote that is not cost-to-deliver. Higher = more room to negotiate.
Step 12: Savings potential
savings = $16,570 - $14,448 = $2,122
The gap between the typical quote and the lowest likely estimate in Seattle.
Each metro's numbers come from the same parts list, assembled with local inputs. Sources: BLS OES wages, FRED PPI series, Craftsman National Estimator, city permit offices. Updated 2026-08-28. Full methodology →

Seattle roofing sits 13.7 percent above the national average. That gap comes from high home values and a compressed building season. The verified floor is $14,448 and the city average is $16,570, and the four dry months between them are where the padding gets in.
Numbers on this page come from Craftsman labor hours, BLS OES May 2025 wages for Seattle, FRED material prices, and the verified local permit fee. Population, income, home values and housing age come from the U.S. Census Bureau (QuickFacts and the American Community Survey); unemployment from the BLS Local Area Unemployment Statistics; building permits from the Census Bureau via FRED.

Local Market
Seattle's median home value runs about eight times its $116,068 median household income, which prices out plenty of upper middle earners. That tension shows up in roofing bids. The city average lands at $16,570 while the national average is $14,568 (TheFatBook cost index, 2026). Local labor runs higher too. The index uses 71.8 craftsman hours at a loaded wage of $52.85 per hour from BLS OEWS wage input. Add in FRED PPI materials at $5,056 plus NAHB overhead of $3,966 and you reach a cost to deliver of $12,817. Metro unemployment stands at 4.5 percent as the tech sector cools. That softness may ease contractor demand and keep some pressure off prices. The extended rainy season from October through May squeezes the work into a narrow window, so most roofs get replaced between June and September. Wildfire smoke can shut sites down in late summer too. Those constraints help explain why Seattle roofing prices sit where they do.
I've read the numbers on Seattle. Call it fifty three an hour loaded after burden and you're in the ballpark. That five percent unemployment in tech may loosen up some labor but the rainy season from October to May still squeezes every crew into four good months. Housing stock from 1976 means a lot of rotted decking under old shingles too. Take that to the bank and pay the man.
Understanding Your Bid
A bid at $16,570 is not automatically fair (TheFatBook cost index, 2026). The cost to deliver sits at $12,817. That produces a 22.6 percent contractor margin on the average price. The verified floor is $14,448. That leaves $2,122 of potential savings between the average and the lowest realistic price. I see bids hit the high end of $18,855 when contractors pad labor or disposal. The floor isn't what it costs to deliver. It's the modeled bottom of the fair band after a lean sustainable margin for this market. Some contractors simply charge what the Seattle market will bear.
Break the $16,570 average down and the numbers get mechanical fast (Craftsman, 2026). Labor eats $3,795. That comes from 71.8 craftsman hours at the loaded rate of $52.85 per hour. The base BLS wage is $35.21 and the burden adds 50.1 percent for taxes insurance and benefits. Materials land at $5,056 after FRED PPI adjustment. Permit fees show zero for this scope though local taxes can still apply. Overhead and site costs including disposal run $3,966 per NAHB benchmarks. Add it up and the cost to deliver equals $12,817. Everything above that's margin. The floor of $14,448 sits between the delivery number and the average. That spread is where negotiation lives. Seattle contractors who bid close to the floor usually run tight crews and buy materials sharp. Yet the ones who land near nineteen thousand often build in extra for the short work window and high home values.
The disposal and overhead line is where I see the most fluff on roofing bids. Your data shows almost four thousand there. A shady outfit will bury extra dump fees and call it overhead. Ask to see the landfill ticket and the material invoice. If both look clean the price is probably straight. Sounds about right.
How to Negotiate
Shop your roofing job in the shoulder months if you can. The rainy season shuts down work from October through May so bids soften in early fall and late spring when crews hunt for volume. The cooling tech sector and 4.5 percent metro unemployment may give you a bit more leverage than you had two years ago. Know the numbers before you sit down. The average is $16,570 and the lowest realistic price is $14,448. Ask the contractor to walk you through his labor hours and material sourcing. A fair one will explain why his price sits where it does. Push too hard on the floor and you risk quality shortcuts on flashing or underlayment. Aim for the middle of the fair range instead.
Red flag for me is any bid near nineteen thousand that doesn't spell out the underlayment and flashing details. In a market with that short summer window good contractors lock in the work early and explain the schedule. If the guy just quotes high and shrugs at the calendar walk away. Ignore these numbers and you'll pay more than you should.
In Seattle a median home value of $938,600 against a $116,068 median income still produces only 45.4 percent home ownership. That math changes roofing bids in ways you don't see in Dallas or Atlanta. Contractors know owners are stretched so they protect margin harder. The housing stock built around 1976 means many roofs sit on decks that have seen decades of rain. Tear off surprises happen more often here. The statewide energy code updates don't touch roofing directly yet they remind every homeowner that every major project now carries higher baseline costs. I keep coming back to the $0 permit line in the data. No standalone permit for asphalt shingle replacement sounds like a gift until you realize the real friction lives in the compressed summer window and the disposal fees hidden inside that $3,966 overhead number. Other cities spread the work over more months. Seattle doesn't. That single fact explains more of the premium than anything else.
