Roof Replacement Cost in Washington (2027 Price Guide)
Use your home size and roof pitch in Washington
Change the size or pitch and every price below reprices. We start at 7/12, a common Washington slope; at 9/12 and steeper, expect harness and jack work in the bid.
Expect quotes near $15,370 to $23,430 for a standard shingle re-roof in Washington; that figure assumes a typical 2,180 sq. ft. single-story house. The job we priced has 26.7 squares of roofing (2,671 sq. ft.) on a 7/12 slope; removing one existing layer, labor and materials are all counted.
Roofers bid by the square, which is a hundred square feet of roof; here the installed rate works out to $701.88 a square. Upgrades change the picture: $17,090 to $26,040 for 50-year architectural shingles, or a starting point near $33,080 for steel shingles.

Price per Year of Roof
The real cost of a roof is price divided by the years it lasts. Hover a bar: metal costs more up front and less per year.
Service lives follow the climate-bell model above (asphalt peaks in moderate regions; metal assumes correct installation); prices are the Washington estimates above.
Pricing Variables in a Washington Re-Roof
Before you rank quotes by price, check that they cover the same work. Our model values each variable on the 26.7-square roof like this:
- Removal. Stripping one layer is worth about $4,490 here. Ask the roofer to confirm the layer count up front; a second one adds about $2,910.
- Geometry. Four-sided hip roofs run about $1,850 above a gable; heavily cut-up roofs with dormers sit about $3,130 above it.
- Building height. Same roof, two stories up: about $1,330 more, mostly labor and safety staging.
- Roof windows. Each skylight in the scope adds roughly $420 - cheaper now than as a separate job later.
- Hidden rot. Water-damaged boards appear once the roof is open; settle the per-sheet replacement price in writing first.
- Flashing and ventilation. Reusing old flashing saves a little now and causes leaks later. Gutters are a separate trade line; the gutter cost calculator covers them.
- Permit and disposal. Fees depend on the town. Confirm the bid includes both the permit and the dumpster.

$18,750quotes usually $15,370 – $23,430
Same 2,671 sq. ft. roof at 7/12, priced with our roofing and metal calculators at Washington rates. Decking repairs, skylights and gutters are extra.
Ask each bidder to fill in the same list: tear-off layers, underlayment, ice barrier, flashing, vents, decking rate, permit. Gaps in that list explain most low bids.
Washington Climate and Roof Wear
Climate Region 2 on the map below covers Washington. Average winter highs run about 37°F, overnight lows about 26°F, and summer afternoons about 80°F. What that means for materials and installation in Washington:
Persistent damp. Moss mats trap water against the roof and pry shingles up. Remove it gently and pick shingles made to resist growth.
Sea breeze. Salt-laden air shortens the life of exposed steel on a roof. Upgraded fasteners and aluminum or coated flashing are worth asking for near the coast.
Cold snaps. Repeated freezing and thawing pries at nail holes, seams and flashing. Ask for ice barrier along the eaves and new flashing everywhere the roof meets a wall.
Where Shingles Live Longest: the Climate Bell
Asphalt life peaks in the moderate middle (Region 3) and falls toward BOTH ends of the map above - cold regions destroy shingles with ice dams, hot ones bake them. Note the middle columns: shingles marketed as “lifetime” are good for about 25 real-world years at best - Washington is Region 2. Hover any column.
low pitch holds snow and ice - it costs the most years in cold regions
Planning figures from our climate model, for ventilation-correct installs - a baked, unvented attic can take years off any column. Pitch adjusts the asphalt columns only; metal sheds snow at any sane pitch.

Is Metal Worth It in Washington?
Most metal bids in Washington fall into one of the types below. Each line is priced for a typical 2,180 sq. ft. single-story house, the same way our metal roof calculator does it.
- Standing seam: $44,090 to $67,210. One panel covers the whole run from the ridge down to the gutter, so water has almost no joints to find. Roofers like it on low pitches and simple gables. The premium over architectural shingles here is roughly $32,940.
- Steel shingles: $33,080 to $50,420. Aluminum shingles: $36,580 to $55,750. If the neighbors would frown at ribbed panels, this is the answer. From the curb they read as shingles or shake. Aluminum is lighter and never rusts; steel costs less and takes a hailstone better.
- Stone-coated steel: $45,030 to $68,630. A steel base under a granule finish. You get the tile look at a small part of the weight of real tile.
- Copper: custom quote only. Copper is a craft job, so we leave it out of the calculator and you will need a custom bid. It costs the most of any metal by a wide margin. A small copper accent over a bay window gives you the look without the whole-roof bill.
Shingle roofs in Washington often fail at the eaves first, where ice builds up and water backs in. Metal is slick, so snow lets go before that ice ridge can form. The edge stays sound, and the roof can go two or three times as long as asphalt.
Moss struggles to grip metal, which keeps maintenance low through the wet months. Think about your timeline: metal's higher price spreads across many more years, but only if you are there to use them. Use the metal roof calculator to price your exact panel type.

Roofing Season in Washington
Roofing work clusters in the dry part of the year here. Book in late winter or early spring - the best crews fill up before the rain stops.
Flat and Low-Slope Roof Prices in Washington
Membrane roofing covers what shingles cannot: flat porches, garages, additions and row-house tops. On a 2,180 sq. ft. footprint:
- EPDM rubber: $19,890 to $25,830. Old-school rubber roofing, and still a fair choice. It takes a hailstorm and a hard freeze in stride. The dark color soaks up sun, so it fits best where nobody lives right under it.
- TPO, 60-mil: $17,120 to $22,230. It goes down in sheets that the crew fuses together with a hot-air gun, so there are no glued seams to fail. A common pick when the flat roof sits over a bedroom or a kitchen.
- PVC, 60-mil: $20,690 to $26,880. Also white and heat-welded, but tougher against grease, chemicals and standing water. It is the pick for roof decks, low spots that hold puddles, and anything near a kitchen exhaust.
From cheapest to most expensive here: TPO, then EPDM, then PVC. Both insulation board and old-layer removal are in the numbers. Per square foot, small flat roofs cost noticeably more than large ones. Make sure a new flat roof drains completely; trapped water and winter freezes are a bad combination. Need another membrane or insulation level? The flat roof calculator prices it.
In Washington winters a dark EPDM roof picks up a little sun warmth, which helps snow melt off. Drainage matters more: water that freezes in a low spot pries seams apart.

Answers for Washington Homeowners
How can I check the size a roofer quoted?
Roofers measure surface, not floor area. The 2,180 sq. ft. footprint in this guide turns into about 2,671 sq. ft. of roof at 7/12 - 26.7 squares. Different counts between bids are a red flag.
Who pulls the roofing permit in Washington?
In most places, a complete replacement needs a permit and may need an inspection. Your roofer should apply for it; a request that you do it yourself is a warning sign.
Does homeowners insurance cover roof replacement?
Covered: hail, wind, fallen trees. Not covered: age and wear. With asphalt at $15,370 to $23,430 in Washington, it pays to read your roof settlement terms now, not after a storm.
How many working days does a new roof need?
Plan on a few days at most for an asphalt roof around 2,671 sq. ft. Complex shapes, a second layer or bad weather can stretch it.
