Seattle, WA

Find a roofing contractor in Seattle, WA who has opened up a house like yours

A reroof in Seattle is rarely just a covering swap. On a house from the 1900s to the 1920s the crew may find spaced boards rather than a solid deck, a porch roof too flat for shingles, an unreinforced brick chimney coming through the middle of it, and nowhere on the street to park the lorry. What separates the bids is how honestly each of those has been priced.

Why do Seattle reroof quotes vary so much on older houses?

Because the unknowns sit under the shingles. Original cedar-shingle roofs were laid on spaced boards, not a continuous deck, and much of the city still has them. Whether the bid covers new sheathing, the low-slope porch, and reflashing a masonry chimney explains most of the gap between a cheap number and a complete one.

There may not be a deck under there

Houses originally roofed in cedar shingle were built on spaced boards with gaps between them, because cedar needs to breathe from below. When those roofs were later covered in asphalt, many were laid straight over the spacing. A tear-off exposes it, and the roof then needs a continuous surface before new underlayment goes down. That is a genuine and legitimate cost, and it is the single most common reason a Seattle reroof price moves after the crew arrives. Ask for it in the bid as a defined unit rate per sheet rather than an open-ended extra.

The flat bits hiding in a pitched roof

Bungalows and box houses put low-slope roofs where you do not think to look: over the front porch, behind a shed dormer, on a rear addition someone tacked on in the 1950s. Asphalt shingles do not perform below their rated pitch no matter how neatly they are laid, and a good number of persistent leaks in this city trace back to exactly that. A proper quote names a membrane system for those areas and describes how it is terminated where it meets the shingled roof.

The chimney is usually the leak, and sometimes the bigger question

Water rarely comes through the field of a roof. It comes in at the chimney, where old mortar-set flashing has failed, and at skylight kerbs, valleys and pipe penetrations. On a house of this age the chimney raises a second point as well: unreinforced masonry stacks are poorly braced against ground shaking, and this is an earthquake region. If the flue is no longer serving anything, taking the stack down to below the roof line while access is already paid for solves the leak and the hazard in one visit.

Ventilation, and moisture arriving from inside

Old attics here were built with almost no deliberate ventilation, and once a house has been insulated and draught-sealed, the water that rots sheathing frequently comes up from the living space rather than down through the roof. Damp staining on the underside of the boards in a dark, still attic is a sign of that. A reroof is the moment to sort intake at the eaves and exhaust at the ridge and to make sure bathroom and kitchen ducts terminate outside rather than into the roof space.

Access on a Seattle street is part of the price

A house on a narrow arterial, a steep block or a lot with no off-street parking is more expensive to reroof than the same house with a driveway and a turning space. There may be no room for a dump trailer without a street use permit, tear-off may have to be carried rather than chuted, and material lifts get awkward on grade. Local crews price this openly. A quote that has never seen the property tends to correct itself upwards on the first morning.

Good to know locally

Registration, bond, insurance — check all three

Roofing attracts door-knockers, particularly after a windy week. Every contractor bidding your roof must be registered with Washington Labour and Industries, carry a surety bond and hold liability cover, and the state's free lookup will show you the status and the expiry dates in under a minute. Confirm the registered legal name matches the business name printed on the bid before you sign anything.

Everybody wants the same dry weeks

Tear-offs need a settled stretch of dry weather and warmth enough for shingles to seal down, which compresses replacement work into the summer months and fills good crews' books well ahead. Booking in late winter or early spring usually gets you a better slot and a crew that is not rushing between jobs. Repairs can be done in dry breaks through most of the year.

Where a reroof crosses into permit territory

A straightforward covering replacement is a comparatively light permit process. It changes once structural sheathing or framing is replaced, a chimney is altered, or the work forms part of a wider project, at which point SDCI review enters the picture and the timescale is weeks rather than days. Ask which route your job takes at bid stage, because the answer belongs in the schedule rather than in a surprise.

What a reroof costs in Seattle

Seattle sits above the national average for roofing, and on older housing the spread within the city is wide. Read the following as bands, not as quotations. An architectural asphalt reroof on an ordinary single-family house, with full tear-off, new underlayment and new flashings, generally runs into five figures, rising with roof area, pitch, the number of dormers and penetrations, how many layers come off and how difficult the site is to reach. Membrane work on low-slope areas, new sheathing over spaced boards, and chimney work are each priced on top and each should appear as its own line. Standing-seam metal costs appreciably more at the outset and lasts far longer, which makes it a question about how long you intend to stay rather than a question about value. Repairs are a different order of money entirely — a failed pipe boot or a section of flashing is a modest job. Confirm whether retail sales tax on labour is inside the number, since Washington charges it, and treat a bid several thousand below the others as a bid that has quietly left something out.

Frequently asked questions
How do I know whether I need a full reroof or a repair?

Age and pattern. Isolated staining traced to one penetration or a length of flashing is a repair. Granules collecting in the gutters, curling and lifting across whole slopes, or a covering already past twenty years in this climate points to replacement. A worthwhile inspection includes a look in the attic, because the underside of the sheathing tells you more than the surface does.

What should be itemised in a roofing bid?

Shingle line and manufacturer, underlayment type, where self-adhered membrane goes at valleys and penetrations, whether flashings are new or reused, the system used on any low-slope area, ventilation at eaves and ridge, a unit rate for replacing sheathing, debris removal, and the warranty terms. Bids specified to that level can be compared. Bids that say tear off and replace cannot.

Can they roof over the existing shingles?

It is occasionally permitted and rarely wise on a house of this age. An overlay hides the deck, so nobody sees whether the boards are spaced or rotten, it adds weight, and it runs hotter. Most manufacturers will not warrant it. On an old Seattle house the deck condition is precisely the thing you are paying to find out about.

What is the right way to deal with moss?

Gentle removal rather than pressure washing, which strips the granules and takes years off the roof. Follow it with a metal strip near the ridge so rain carries a trace of it down the slope, and cut back the overhanging branches keeping that side of the roof permanently damp. Without the branch work, it simply comes back.

Should the gutters and downpipes be done at the same time?

Usually worth pricing, because the fascia is exposed and the crew is already up there, so the added labour is small. It matters more here than in drier places, since the volume of water coming off a roof through the wet half of the year is what keeps a foundation dry or does not.

Will my insurance pay for storm damage?

Sudden damage from an identifiable wind event is often covered; gradual wear, moss deterioration and old flashing generally are not. Photograph everything with dates, get a written assessment from a registered contractor, and report it promptly. Be sceptical of anyone who turns up uninvited afterwards offering to handle the claim on your behalf.

What does it cost me to use this service?

Nothing whatsoever. Describing the roof and receiving quotes is free, and there is no fee to us if you go on to hire one of the roofers. The only payment involved is the one you agree with the contractor for the work.

How many roofers will get in touch with me?

Generally two to four, matched on the type of roof, the size of the job and whether they really work your neighbourhood. Only those few see your contact details. We do not resell enquiries and your information is not distributed any further.
