Roof Replacement Cost in Washington (2026)

Up-to-date 2026 prices per square and per home, plus the local code and climate factors that move your bid.

Quick answer: A new asphalt shingle roof in Washington costs about $12,500 – $18,000 for a typical 25-square roof (about 2,500 sq ft of roof surface), or $500 – $720 per square installed with tear-off. Standing-seam metal runs $990 – $1,540 per square.

What the data says about roofing in Washington

BLS counts about 4,840 roofers working in Washington, with a mean wage of $31.94 an hour — 16% above the US mean of $27.44. Construction laborers, who handle tear-off and clean-up, average $29.03 (18% above the US). At median wages a four-person crew (three roofers and a laborer) costs about $114.55 an hour in pay alone, before the contractor's insurance, overhead and margin.

On the materials side, BEA puts Washington's price level for goods at 104.4 against a US figure of 99.6, so shingles, underlayment and flashing run about 5% above the national average. Labor moves the Washington price more than materials do, so comparing several itemised bids is where the savings are. Overall Washington ranks 43 of 50 from cheapest to most expensive on this index (combined factor 1.100).

How the Washington prices are calculated

1. Start from our national installed prices per square: $450–$650 architectural shingles, $900–$1,400 metal, $1,200–$1,800 tile.
2. Labor share: about 45% of an asphalt job (our labor cost per square figures), materials the other 55%.
3. Labor index = Washington roofer mean wage ÷ US mean = $31.94 ÷ $27.44 = 1.164.
4. Materials index = goods RPP ÷ US goods RPP = 104.4 ÷ 99.6 = 1.048.
5. State factor = 0.45 × 1.164 + 0.55 × 1.048 = 1.100, applied to each national band and rounded to $10: $500–$720/sq shingles, $990–$1540 metal, $1320–$1980 tile.

Cost for a typical Washington home

For a 2,000 sq ft single-family home (≈ 20 roofing squares with average pitch and waste), expect:

• Asphalt (architectural): $10,000 – $14,400
• Standing-seam metal: $19,800 – $30,800
• Concrete or clay tile: $26,400 – $39,600
• Permit fees: ~$320

New roof cost by house size in Washington

Squares assume a 6/12 pitch and 10% waste. A one-storey house has a roof footprint about equal to its floor area; a two-storey house of the same floor area has roughly half the footprint, so half the roof. Steeper roofs, dormers and a second tear-off layer push the figure up.

Roof replacement cost in smaller Washington towns

Most searches for a town-level price — a small town or a county seat in Washington — land on the state range above, because local quotes are built from the same three things everywhere: the roof's size in squares, the material, and the local labour rate. Rural and small-town crews often quote toward the lower half of the Washington range; jobs that need a long drive, steep terrain, staging or a dumpster on a tight lot quote toward the top. Where we publish a city page below, it applies a local multiplier to the state baseline.

Work out your own roof price

1. Measure the house footprint to the outside of the eaves (length × width for each rectangle) and add the pieces.
2. Multiply by the pitch factor for your roof (1.118 for 6/12; the roof pitch chart lists every pitch) to get the sloped roof area.
3. Add 10% for waste on a simple gable, 15% on a hip roof, then divide by 100 to get squares.
4. Multiply the squares by $500 – $720 for architectural shingles in Washington, and add the permit (about $320).

Measure with the roof area calculator, look up your pitch factor on the roof pitch chart, or let the project estimator do all four steps.

What drives roofing cost in Washington

How Washington compares with neighbouring states

Across the state line the same roof is priced at: Oregon $470 – $680 per square, Idaho $420 – $600 per square, Alaska $500 – $720 per square. A contractor based over the border prices from their own labour market, so on a job near the line it is worth getting one quote from each side.
