A new roof in Washington State costs about $12,500 to $20,000 for a 2,000 sq ft architectural asphalt roof in Seattle and about $11,600 to $18,600 in Spokane, sales tax included, in a Roofing Brief estimate built from BLS roofer wages and Department of Revenue tax rates. Published Washington guides range from an $8,118 modeled average to $28,000. Two things set Washington apart: roofers here earn about 18 percent more than the U.S. mean, and sales tax applies to the whole contract, labor included.

Wage figures are BLS Occupational Employment and Wage Statistics (OEWS) May 2025 estimates; tax rates are from the Washington Department of Revenue rate file effective October 1 to December 31, 2026; code and registration rules were read from the Washington Administrative Code, the Revised Code of Washington and Seattle and Spokane Valley permit documents; climate figures are NOAA 1991 to 2020 normals. We did not survey contractors or collect bids; every estimate below shows its arithmetic.
Washington roof replacement cost: key numbers at a glance
These are the figures a Washington homeowner usually needs before the first estimate. Each comes from a named source, and each cost is a range that moves with roof size, pitch, material, tear-off layers and location. Use them to test whether a bid sits in a normal band, not as a price any contractor owes you.

How much does a new roof cost in Washington State in 2026?
A new roof in Washington State usually costs $11,000 to $28,000 for an asphalt shingle replacement on a typical house, with metal, cedar and synthetic shake roofs running higher. The published figures disagree because they price different jobs: some model a small, simple roof from national cost databases, while contractor calculators price a median Washington house with tear-off. Few of them say whether sales tax is in the number.
The table below lines up the Washington figures that rank in search today, with what each one actually prices. Read the scope column before you compare a bid against any single number.
| Published Washington figure | What it prices | Source |
|---|---|---|
| $8,118 average; $6,156 to $20,811 range | RSMeans-based model, asphalt at $4.43 per sq ft, median home size | This Old House, Washington roof replacement cost (updated June 12, 2026) |

The spread is mostly scope. This Old House’s asphalt rate of $4.43 per sq ft sits below the $5 to $8 national architectural range in our 2026 Roofing Cost Report, so its total reads like a basic roof. Cost vs. Value prices a large, fully specified job. The rest of this guide shows how to get from the national baseline to a Washington number you can check, and our national roof replacement cost guide covers the general method.
Washington sales tax on roofing labor: the cost most estimates leave out
Washington charges retail sales tax on the full price of a residential roof replacement, not just the shingles. WAC 458-20-170(4)(a) says prime contractors “are required to collect from consumers the retail sales tax measured by the full contract price.” At Seattle’s 10.55 percent rate, a $20,000 roof carries $2,110 in tax. Many states tax only materials, so national price guides can understate a Washington bill.
The rate follows the job address, not the contractor’s office, and it changes by quarter. The figures below are the Department of Revenue combined rates for October 1 to December 31, 2026; the state share is 6.5 percent everywhere. Check the address in the Department of Revenue rate lookup before you sign, because unincorporated county areas often carry a lower rate than the city next door.
| Job location | Combined rate (Q4 2026) | Tax on a $15,000 roof | Tax on a $20,000 roof | Tax on a $25,000 roof |
|---|---|---|---|---|
| Seattle | 10.55% | $1,583 | $2,110 | $2,638 |
| Tacoma | 10.5% | $1,575 | $2,100 | $2,625 |
| Bellevue | 10.3% | $1,545 | $2,060 | $2,575 |

Why Seattle roofs cost more than Spokane or Yakima roofs
Labor is the main reason Washington roof prices vary by region. In May 2025 BLS data, roofers in the Seattle-Tacoma-Bellevue metro averaged $35.21 an hour, 26 percent above the U.S. mean of $27.95, while Spokane roofers averaged $31.54 and Yakima roofers $29.77. Labor is often 40 to 60 percent of an installed roof, so the wage gap passes into bids, though not dollar for dollar.
Washington also employs an unusually large roofing workforce: 5,890 roofers in May 2025, with a location quotient of 1.9, meaning roofers make up nearly twice the share of jobs that they do nationally (BLS OEWS). Our roofer salary by state ranking puts every state on the same scale.
| Area | Roofer mean hourly wage | Ratio to U.S. mean | Roofer median hourly wage | Estimated price multiplier (50% labor share) |
|---|---|---|---|---|
| United States | $27.95 | 1.00 | $26.65 | 1.00 |
| Washington (statewide) | $33.11 | 1.18 | $29.16 | 1.09 |
| Seattle-Tacoma-Bellevue | $35.21 | 1.26 | $30.81 | 1.13 |
| Mount Vernon-Anacortes | $33.38 | 1.19 | $29.52 | 1.10 |
| Portland-Vancouver-Hillsboro (OR-WA) | $32.13 | 1.15 | $29.43 | 1.07 |
| Bremerton-Silverdale-Port Orchard | $31.56 | 1.13 | $28.59 | 1.06 |
| Spokane-Spokane Valley | $31.54 | 1.13 | $28.23 | 1.06 |
| Kennewick-Richland | $31.01 | 1.11 | $28.73 | 1.05 |
| Bellingham | $30.58 | 1.09 | $28.72 | 1.05 |
| Wenatchee-East Wenatchee | $30.50 | 1.09 | $28.48 | 1.05 |
| Olympia-Lacey-Tumwater | $29.78 | 1.07 | $27.85 | 1.03 |
| Yakima | $29.77 | 1.07 | $27.24 | 1.03 |
| Walla Walla | $25.56 | 0.91 | $23.74 | 0.96 |
Source: BLS OEWS May 2025, roofers (SOC 47-2181), state and metro estimates. Metro hourly figures are the published annual wage divided by 2,080 hours, the BLS convention. The multiplier column is a Roofing Brief estimate: half the installed price is treated as labor and scaled by the mean wage ratio (for Seattle, 0.5 + 0.5 times 1.26 = 1.13). Inch Calculator puts labor at 40 to 50 percent of installed cost and NerdWallet at more than half, so treat the multiplier as approximate.
Workers’ comp: why every roofing crew hour costs more in Washington
Washington charges workers’ compensation premiums per hour worked, and most employers buy coverage from the Department of Labor and Industries State Fund. For 2026, the composite base rate for class 0507, Roof Work: Construction and Repair, is $5.7930 per hour, about 7.3 times the $0.7885 average across all classes. Every 100 crew hours on a reroof carry about $579 in base-rate premium before experience adjustments.
That premium sits inside the price a registered, insured roofer quotes. A bid far below the others can mean a contractor who is not reporting hours to L&I, which leaves you exposed if a worker is hurt on your roof. The registration check later in this guide shows how to confirm coverage.
Worked example: reroofing a 2,200 sq ft house in Seattle, Spokane and Yakima
A one-story 2,200 sq ft house with a 6/12 roof has about 2,680 sq ft of roof surface (26.8 squares), using the same pitch and overhang allowance as our 2,000 sq ft roof cost guide. In architectural asphalt, that roof estimates at about $16,700 to $26,800 in Seattle, $15,600 to $24,900 in Spokane and $15,000 to $24,000 in Yakima, sales tax included, before any decking repair.
| Step | Seattle | Spokane | Yakima | Basis |
|---|---|---|---|---|
| 1. Roof surface | 2,680 sq ft | 2,680 sq ft | 2,680 sq ft | One-story 2,200 sq ft house, 6/12 pitch, standard overhangs |
| 2. National baseline at $5 to $8 per sq ft | $13,400 to $21,440 | $13,400 to $21,440 | $13,400 to $21,440 | The Roofing Brief 2026 Roofing Cost Report |
| 3. Labor adjustment (multiplier) | 1.13 | 1.064 | 1.033 | BLS OEWS May 2025 mean wage ratio, 50% labor share |
| 4. Adjusted price before tax | $15,141 to $24,225 | $14,261 to $22,818 | $13,837 to $22,140 | Step 2 times step 3 |
| 5. Labor premium over national | $1,741 to $2,785 | $861 to $1,378 | $437 to $700 | Step 4 minus step 2 |
| 6. Sales tax | 10.55%: $1,597 to $2,556 | 9.1%: $1,298 to $2,076 | 8.6%: $1,190 to $1,904 | WA Department of Revenue, Q4 2026 |
| 7. Total with tax | $16,738 to $26,781 | $15,559 to $24,895 | $15,027 to $24,044 | Step 4 plus step 6 |
| 8. If 3 to 6 deck sheets need replacing | add $212 to $1,061 | add $209 to $1,047 | add $209 to $1,043 | 96 to 192 sq ft at $2 to $5 per sq ft installed (HomeGuide), plus tax |
The result most guides miss sits in rows 5 and 6. In Seattle, sales tax adds about as much as the region’s labor premium. In Spokane and Yakima, the tax adds more than the labor premium does. A two-story 2,200 sq ft house carries roughly 1,400 sq ft of roof, which estimates at about $8,700 to $14,000 in Seattle with tax. Steep pitch, extra layers, skylights and chimneys push any of these figures up; our tear-off and reroof pricing guide itemizes those adders.
Washington roof cost by material
Architectural asphalt is the price floor for most Washington reroofs at about $5.50 to $8.70 per sq ft before tax in our statewide estimate, while standing seam metal and cedar shake run about $10.90 to $19.70. Material choice moves a Washington bid more than any other single decision, often by $10,000 or more on the same house. For a shingle brand made in Tacoma, our review of PABCO roofing shingles compares its lines on wind rating, warranty and price.

|---|---|---|---|---|---|
| 3-tab asphalt | $4 to $6 | $4.37 to $6.55 | $9,993 to $14,989 | $9,289 to $13,934 | $10,000 to $14,700 |

Washington roof cost by roof size
Roof size is the second biggest lever after material. For architectural asphalt, a 1,500 sq ft roof surface estimates at about $8,200 to $13,100 statewide before tax, while a 3,000 sq ft roof runs about $16,400 to $26,200. Add 8.1 to 10.55 percent sales tax depending on the address. Roof surface is measured on the slope and is larger than the floor area of a one-story house.
| Roof surface (squares) | Statewide, before tax | Seattle, with tax | Spokane, with tax | Yakima, with tax |
|---|---|---|---|---|
| 1,200 sq ft (12) | $6,554 to $10,486 | $7,495 to $11,991 | $6,967 to $11,147 | $6,729 to $10,766 |

Wet west, snowy east: how climate changes a Washington roof job
Washington is two roofing markets split by the Cascades. Seattle averages 39.34 inches of precipitation a year with 93 days of a tenth of an inch or more, but only 6.3 inches of snow. Spokane gets 16.45 inches of precipitation, 45.4 inches of snow and 132 nights at or below freezing. West-side bids spend more on moss prep and wet decking; east-side bids spend more on eave and snow details.
| Station (1991 to 2020 normals) | Annual precipitation | Days with 0.10 in. or more | Annual snowfall | Days with low at or below 32°F | What it tends to add to a roof scope |
|---|---|---|---|---|---|
| Seattle-Tacoma Intl. Airport | 39.34 in. | 93.4 | 6.3 in. | 25.2 | Moss removal, rotted deck sheets, valley and wall flashing, attic ventilation fixes |
| Spokane Intl. Airport | 16.45 in. | 52.9 | 45.4 in. | 132.0 | Ice barrier at eaves where required, snow-shedding details, freeze-cycle flashing |
| Yakima Air Terminal | 8.01 in. | 26.3 | 20.3 in. | 147.4 | Freeze-thaw at eaves and penetrations; summer heat on dark shingles |
Source: NOAA National Centers for Environmental Information, U.S. Climate Normals 1991 to 2020, annual and seasonal normals for stations USW00024233, USW00024157 and USW00024243. The scope column describes common work items, not a NOAA finding.
Moss and wet decking west of the Cascades
Moss is a scope item, not a defect, on many Puget Sound roofs, and it changes the bid. Professional moss removal runs about $0.20 to $1.00 per sq ft, according to our roof moss removal cost guide. Shingle makers and the Asphalt Roofing Manufacturers Association describe a diluted bleach wash left for 15 to 20 minutes and a low-pressure rinse, never a pressure washer, which can strip granules.
On a full replacement, the moss comes off with the old roof, so the bigger cost is what sits underneath. Long wet seasons can leave soft or delaminated sheathing at eaves, valleys and below moss mats. Ask for a per-sheet decking price in writing; our roof decking replacement cost guide covers OSB and plywood pricing. ARMA does not recommend retrofitting zinc or copper strips to an existing roof; algae-resistant shingles on the new roof are the cleaner route.
Snow, ice barrier and eaves east of the Cascades
Whether your roof needs an ice barrier depends on your local building department, not the state. Under 2021 IRC Section R905.1.2, an ice barrier is required where the jurisdiction’s Table R301.2 says there is a history of ice forming at the eaves, and it must run from the eave edge to at least 24 inches inside the exterior wall line. Each city or county fills in that table.
Some Puget Sound jurisdictions answer yes too; the City of Des Moines design criteria table, for example, lists ice barrier underlayment as required. On a 30-square roof, eave ice barrier is a modest line item, but missing it can fail an inspection where it applies. Ask your roofer what your jurisdiction’s Table R301.2 entry says.
What changes the price of a roof replacement in Washington
Seven drivers explain most of the gap between two Washington roof bids: local labor rates, sales tax at the job address, workers’ comp premiums, tear-off layers, decking condition, material, and permit or energy-code triggers. The table maps each driver to its effect and a source, so you can see which line on a quote it should show up in.
| Driver | Effect on a Washington bid | Source |
|---|---|---|
| Metro labor rates | About +13% on the installed price in the Seattle metro, about +3% in Yakima and Olympia, versus the U.S. baseline | BLS OEWS May 2025; Roofing Brief estimate |
| Sales tax on the full contract | +8.1% to +10.55% of the whole price, labor included | WAC 458-20-170; WA DOR Q4 2026 rates |
| Workers’ comp | $5.7930 per crew hour base rate for roof work, inside the contractor’s overhead | Washington L&I 2026 rates, class 0507 |
| Existing layers | Two or more layers rule out an overlay, so full tear-off and disposal are required | 2021 IRC R908.3.1.1, adopted in WAC 51-51 |
| Deck condition | $2 to $5 per sq ft installed for replaced sheathing, plus tax | HomeGuide (decking installed cost) |
| Moss and shade | $0.20 to $1.00 per sq ft if treated separately; more deck repair under heavy mats | The Roofing Brief moss removal cost guide |
| Material | Standing seam or cedar roughly doubles the architectural asphalt price | The Roofing Brief 2026 Roofing Cost Report |
| Envelope or energy-code triggers (Seattle) | A permit is needed if the reroof alters the envelope; exposed cavities may need insulation to current energy code | Seattle SDCI, Re-Roof Permit page |
Do you need a permit to reroof in Washington?
Washington leaves reroof permits to cities and counties, so the answer depends on the address. Seattle says no permit is required for re-roof work on one- and two-family homes and townhouses unless the work alters the building envelope beyond adding or replacing insulation. Spokane Valley, by contrast, uses a separate re-roof permit application for single-family homes, duplexes and ADUs.
When a Seattle re-roof does need a permit because it alters the envelope, SDCI says the fee is half of its base fee plus the state surcharge, no on-site inspection is required, and the permit is closed with a signed Roof Replacement Affidavit. The Spokane Valley form asks for the contractor’s L&I registration, tear-off or overlay, the number of existing layers and whether the deck will be re-sheeted, and notes that a project “may require a structural analysis.” Our roof permit cost guide compares fees across states.
Which code edition applies to a Washington reroof in late 2026?
The 2021 International Residential Code, as amended by Washington in chapter 51-51 WAC, has applied statewide since March 15, 2024. The State Building Code Council has set May 3, 2027 as the effective date for the 2024 codes, so a reroof permitted in late 2026 still follows the 2021 edition. Local amendments can add rules on top of the state code.
| Rule | What it means for your reroof | Source |
|---|---|---|
| 2021 IRC in force since March 15, 2024 | Reroofing follows IRC Section R908; roof coverings follow R905 | WAC 51-51-008 |
| 2024 codes effective May 3, 2027 | Bids signed now fall under the 2021 rules; confirm if your project slips into 2027 | State Building Code Council; WSR 26-10-071 (proposed rule) |
| Roof recover limits | No overlay where the roof already has two or more layers, or where the old roof is water-soaked or deteriorated | 2021 IRC R908.3.1.1 |
| Ice barrier | Required where the local Table R301.2 says so; eave edge to 24 inches inside the exterior wall | 2021 IRC R905.1.2 |
| Wildland-urban interface code | The 2021 WUI code text was deleted from chapter 51-55 WAC on March 17, 2026, pending new state wildfire maps | WSR 26-07-074 (emergency rule); ESB 6120 (2024) |
The wildfire point matters for cedar. Washington’s 2021 WUI code would have required Class A roofing in mapped interface areas, but the Building Code Council removed that text by emergency rule because ESB 6120 requires new Department of Natural Resources hazard maps first. Emergency rules are temporary, and local fire codes, HOA rules or insurers may still ask for Class A roofing, so check before choosing untreated wood.
Washington contractor registration, bonds and the disclosure notice
Washington does not issue a separate roofing license. Roofers must register with the Department of Labor and Industries as contractors under RCW 18.27, which since July 1, 2024 requires a $15,000 bond for specialty contractors and $30,000 for general contractors, plus liability insurance of at least $50,000 for property damage and $100,000 for injury to one person or $200,000 for injury to more than one person.
The bond is small next to a $20,000 roof and can be split among several claimants, so it is not full protection. Washington adds a second safeguard: under RCW 18.27.114, a contractor on a residential job of $1,000 or more must give you a signed disclosure statement before work begins, warning that “your property may be liened.” A contractor who skips it generally cannot bring or keep a lien claim on that job.

Our roofing contractor red flags checklist covers storm-chaser tactics that show up after windstorms.
Roof age, insurance and the Washington labor-depreciation rule
A Washington homeowners policy generally pays for roof damage from a covered event, such as wind or a falling tree, not for wear and tear. Older roofs are often settled at actual cash value, which subtracts depreciation. Washington limits that: WAC 284-20-010(4), effective January 1, 2022, says labor needed to repair or replace covered property “may not be subject to depreciation or betterment.”
The rule matters most on older roofs, where depreciation on materials can be steep but labor is a large share of the bill. It does not decide whether damage is covered; your policy wording does. Insurers can also decline to renew or change terms on an older roof, which our insurance non-renewal by roof age guide tracks.
| Situation | What usually happens | What to ask |
|---|---|---|
| Windstorm or tree damage, replacement cost policy | Insurer may pay actual cash value first, then the withheld depreciation after the work is done | The deadline to finish work and claim the holdback |
| Damage on an older roof, actual cash value settlement | Materials can be depreciated; labor cannot be under WAC 284-20-010(4) | An itemized estimate that separates labor from materials |
| Moss, rot or age wear with no storm event | Typically excluded as wear, tear or maintenance | Whether any sudden, covered event is involved |
| Renewal on a roof past 20 years | Some insurers ask for an inspection or change roof coverage terms | The insurer’s written roof-age guidelines |
Sources: WAC 284-20-010(4) as adopted by WSR 21-23-066 (Office of the Insurance Commissioner). Coverage and settlement terms vary by insurer and policy; the Washington Office of the Insurance Commissioner takes consumer complaints if a claim stalls.
Tax credits and local help for a Washington roof in 2026
There is no federal tax credit for a homeowner’s new roof in 2026. Public Law 119-21 ended the 25C home improvement credit for property placed in service after December 31, 2025, and the 25D clean energy credit, which covered solar roofing’s power-generating parts, for expenditures after that date. Check current IRS guidance and a tax professional. Some local help does exist for income-qualified owners.
In Seattle, the Office of Housing’s Home Repair Program lists roof repair or replacement as an eligible repair for owner-occupants under 80 percent of area median income. Loans start at $3,000, carry 0 percent interest and are listed up to $24,000, with grants for very low-income households; the city notes funds are limited and new applications go on a waiting list. Outside Seattle, ask your county housing office about repair programs.
Which roof should you pick in Washington?
For most Washington houses, algae-resistant architectural asphalt is the lowest-cost sound choice, and standing seam metal makes sense if you plan to stay long enough to use its longer life. Shade, snow, existing layers and your time horizon change the answer. Match your situation to a row below before you compare prices.
| If your situation is | Then consider | Why |
|---|---|---|
| West-side house under firs or cedars, moderate budget | Algae-resistant architectural asphalt, full tear-off, good attic ventilation | Lowest installed cost; algae-resistant granules and airflow address the wet, shaded conditions |
| Staying 25 years or more | Standing seam metal | Higher price up front, but 40 to 70 year life can mean one roof instead of two |
| Eastern Washington, heavy snow | Asphalt or metal with ice barrier where your jurisdiction requires it; snow retention on metal over walkways | Spokane averages 45.4 inches of snow and 132 freezing nights |
| Existing cedar shake roof | Price cedar, synthetic shake and architectural asphalt side by side | Cedar costs about as much as standing seam; check HOA, fire and insurer rules first |
| Roof already has two layers | Budget for full tear-off and possible deck repair | 2021 IRC R908.3.1.1 bars a third layer |
| Selling within 5 years | Architectural asphalt | Asphalt recouped 68% of cost nationally vs 50% for metal (Cost vs. Value 2025) |
| Storm damage claim open | Settle scope with the adjuster before choosing an upgrade | Upgrades beyond like-kind are usually paid by you |
| Low income, Seattle owner-occupant | Apply to the Seattle Home Repair Program | 0% loans from $3,000; grants for very low incomes; waitlist |

How to check a Washington roof replacement quote
Compare Washington roof quotes line by line, not total by total. The most common reasons two honest bids differ by thousands of dollars are sales tax, tear-off layers, decking allowances and moss or ventilation work. Put every bid on the same scope with this sequence before you decide.
- Confirm each contractor’s active L&I registration, bond and insurance in the Verify a Contractor tool.
- Ask whether the price includes Washington sales tax and which rate was used for your address.
- Confirm tear-off of all existing layers, and how many layers the bidder found.
- Get a per-sheet price for replacing rotted or delaminated decking, and a cap on the count without your approval.
- Match underlayment, ice barrier, drip edge and flashing details across bids.
- Ask who handles the permit, or the Seattle affidavit where applicable, and whether the fee is included.
- Check that moss prep, ventilation corrections and debris haul-off are in writing.
- Compare the manufacturer warranty tier and any registration it requires, plus the contractor’s workmanship term.
- Sign the RCW 18.27.114 disclosure statement, and tie payments to milestones rather than paying most of the price up front.

Frequently asked questions
How much does it cost to replace a roof on a 2,200 square foot house in Washington?
A one-story 2,200 sq ft house with a 6/12 roof has about 2,680 sq ft of roof surface. In architectural asphalt that works out to roughly $16,700 to $26,800 in Seattle and $15,600 to $24,900 in Spokane, sales tax included, in a Roofing Brief estimate built on BLS wages and Department of Revenue tax rates. A two-story house of the same size has about half the roof and roughly half the cost.
Will insurance cover a 20-year-old roof?
It can, if a covered event such as a windstorm or a falling tree damages the roof. Policies generally exclude wear and tear, and many insurers settle older roofs at actual cash value, which subtracts depreciation. In Washington, WAC 284-20-010(4) bars insurers from depreciating the labor portion of a repair, which can raise the payout on an older roof. Read your declarations page and ask your agent how roofs are settled.
Is it cheaper to put a metal roof or shingles?
Shingles are cheaper up front. The 2026 national baseline is $5 to $8 per sq ft installed for architectural asphalt against $10 to $18 for standing seam metal, and Washington labor and sales tax push both higher by a similar percentage. Metal can cost less per year of service if you stay long enough, because standing seam often lasts 40 to 70 years against 20 to 30 for architectural asphalt.
What is the 25% rule for roofing?
The 25 percent rule is a Florida Building Code provision: when more than 25 percent of a roof section is repaired or replaced within 12 months, the whole section may have to meet current code. A 2022 Florida law (SB 4-D) lets roofs already built to the 2007 Florida code or later repair only the damaged part. Washington has no equivalent rule; reroofing follows IRC Section R908 as adopted in WAC 51-51.
Is $50,000 for a new roof good in Washington?
For an asphalt shingle roof on a typical house, $50,000 is high: a 3,000 sq ft architectural roof in Seattle estimates at about $18,700 to $30,000 with sales tax. For standing seam metal, synthetic shake or cedar on a large or steep roof, $50,000 can be a normal price. Ask for an itemized bid and compare at least three written quotes for the same scope.
What is the typical lifespan of a roof in Washington State?
Material sets the baseline: about 15 to 20 years for 3-tab asphalt, 20 to 30 years for architectural asphalt and 40 to 70 years for standing seam metal. West of the Cascades, shade, moss and long wet seasons can shorten the life of asphalt and cedar. East of the Cascades, snow load and freeze cycles stress flashing and eaves. Ventilation and maintenance often matter as much as the product.
Do you pay sales tax on a roof replacement in Washington?
Yes. Under WAC 458-20-170, a prime contractor working for a homeowner must collect retail sales tax on the full contract price, labor included. The rate depends on the job address: 10.55 percent in Seattle, 10.5 percent in Tacoma, 9.1 percent in Spokane and 8.6 percent in the city of Yakima for October to December 2026, per the Department of Revenue. On a $20,000 roof that adds $1,720 to $2,110.
Do you need a permit to replace a roof in Washington?
It depends on the city or county. Seattle says a re-roof of a one- or two-family home or townhouse needs no permit unless the work alters the building envelope beyond adding or replacing insulation. Spokane Valley uses a dedicated re-roof permit application that asks about tear-off, existing layers and re-sheeting. Ask your roofer who pulls the permit and whether its fee is in the price.
