Roof Replacement Cost in Seattle
Every roof is different, so we don't publish one-size-fits-all prices. This guide explains what affects the cost of a roof replacement in the Greater Seattle area and how to read a written estimate.
What affects the cost
Roof area and pitch
Roofs are priced by roof surface area, not the home's floor area. A steeper or more complex roof has more surface, needs more safety setup and takes longer to install.
Tear-off
How many layers of old roofing come off affects labor and disposal. We confirm the number of layers during the inspection.
Decking and hidden damage
Soft or rotted decking is often hidden until the old roof is removed. If we find it, we photograph it and explain any change in scope and price before continuing.
Permits
Many full replacements need a permit, but requirements depend on the city and the scope of work. We check what applies to your address and list it in the estimate.
Flashing and ventilation
New flashing at walls, chimneys and skylights, and attic ventilation that works with your roof, are part of the scope and affect cost.
Access and scheduling
Steep driveways, limited parking and landscaping can affect setup time. Weather can also shift the schedule during the rainy season.
Choosing a material
Material is one of the biggest cost decisions. Each page below explains how the material works and what to consider.
Asphalt / composition shingles
Usually the most budget-friendly option for pitched roofs.
Metal roofing
A higher upfront cost than asphalt, with different installation details.
Synthetic slate and shake-style roofing
A slate or shake look; pricing varies by product.
Flat & low-slope roofing: TPO and PVC
Priced differently from pitched roofs and quoted after an inspection.
How to read your written estimate
- The roofing material and the work included, such as tear-off, underlayment, flashing and ventilation.
- How decking damage found during tear-off will be handled and priced.
- Permits, where required for your address and scope.
- Cleanup, and what is excluded.
- Warranty terms. GripGo offers a 10-year transferable workmanship warranty on full roof replacements and gutter installations, subject to the written terms in your agreement. Manufacturer warranties are separate.
Roof area is not floor area
Roofing is measured by the area of the roof surface, not the floor area of the house. Pitch, overhangs, dormers, hips and valleys all add roof area, so two homes with the same floor area can need very different amounts of material and labor. That is one reason an estimate comes from an inspection rather than from the home's listed square footage.
Comparing estimates fairly
Two estimates are only comparable if they cover the same scope. Check each one for:
- Tear-off and disposal: how many layers come off and whether hauling is included.
- Flashing and ventilation: whether wall, chimney and skylight flashing is replaced, and how the attic will be ventilated.
- Decking changes: how damaged boards found during tear-off are handled, and that extra work needs your authorization first.
- Exclusions: what the estimate leaves out, such as gutters, skylights or interior repairs.
- Access constraints: steep pitches, tight lots or limited parking that affect staging and labor.

Repair or replace?
If the problem is in one area, such as a pipe boot, flashing or a few missing shingles, a roof repair may be the right call. If wear is spread across the roof, leaks keep returning or the decking is soft, replacement is often more practical. We show you photos so you can compare both options.

Roof replacement cost FAQs
How much does a roof replacement cost in Seattle?
It depends on your roof's surface area, pitch, material, tear-off, decking condition, permits and access. Because those vary so much from home to home, we give you a written estimate after inspecting your roof.
Why don't you list prices on this page?
Online ranges can be misleading for a specific home. We'd rather inspect your roof and give you a written estimate that reflects what's actually there.
Does insurance cover roof replacement?
That depends on your policy and the cause of the damage. Insurers generally treat sudden damage differently from age-related wear. Check with your insurer; we can provide photos of what we find.
Is a permit included in the estimate?
When your project needs a permit, we list it in your written estimate.
Are monthly payments available?
Payment options may be available, subject to lender approval and project eligibility. See our financing page for details.
