What a roof costs in Seattle: how estimates are built

A roof quote can feel like a wall of numbers. That worry is fair, because the total is large and the lines are hard to read. This guide breaks an estimate into parts so you can see what you are paying for.

The ranges below are typical, not quotes. Your roof, your materials and local rules will decide the real number. Use the ranges to spot a quote that looks far out of line, then ask the provider to explain it.

Roof replacement: typical ranges

These are the usual pieces of a replacement job.

• Asphalt shingle roof: $5,500 – $12,000. A common choice for average-size homes.
• Metal roof: $12,000 – $30,000. Costs more up front, often lasts longer.
• Tile or slate roof: $20,000 – $50,000. Heavy, and may need extra support.
• Tear-off and disposal: $1,000 – $3,000. Depends on layers and roof size.
• Deck repair: $300 – $2,500. Only if boards are soft or rotted.
• Permits and flashing upgrades: $500 – $3,000. Varies by local rules and roof details.

Not every job needs every line. A clear estimate shows which lines apply to your home and why.

How an estimate is built

Most estimates start with the size of the roof and the material you choose. Then labor, removal of the old roof, and cleanup are added. After that come the details that depend on your house: flashing around chimneys and pipes, vents, and any wood that has to be replaced.

Ask for the estimate itemized. If you see one number with no breakdown, ask for the parts. It makes quotes much easier to compare.

What pushes the price up

• More than one layer of old roofing to remove.
• Rot in the deck, which is more likely after many wet seasons.
• A steep or complicated roof with many angles, valleys or dormers.
• Heavier materials such as tile or slate.
• Tight access, such as a narrow yard or no room for a dumpster.
• Flashing and vent upgrades, or permit requirements that call for extra work.

What can keep it down

• A simple roof shape with few angles.
• A single layer to remove.
• A sound deck that needs little or no repair.
• Standard asphalt shingles instead of specialty materials.
• Clear access for crews and materials.

A low price is not always a good deal. A low number that leaves out tear-off, flashing or deck repair can grow later, so compare what is included.

Smaller repairs: typical ranges

Sometimes a roof does not need replacing. These ranges are for repair work.

• Replace a few shingles: $150 – $500. A small job on a sound roof.
• Flashing or vent repair: $250 – $900. A common leak spot around chimneys and pipes.
• Leak detection and patch: $300 – $1,000. Depends on how hard the source is to find.
• Tarp over damaged area: $250 – $1,000. A short-term cover until repairs are done.
• Section of decking replaced: $500 – $2,500. Rises if rot has spread widely.
• Larger storm damage repair: $1,000 – $5,000. Varies with damage, access and materials.

The request form on this site is aimed at roof replacement, so a small repair may not find a provider match. Repair availability depends on who is working in your area.

Comparing quotes fairly

Lay the quotes side by side. Check that each one names the same material, the same tear-off plan and the same warranty. Look for what is missing, not just what is listed. Ask each provider what would change the price once the old roof is off.

If an insurance claim is part of your situation, ask your insurer what it covers and what it does not. This guide cannot speak to any claim.

Your next step

Write down your roof's age, the material, and anything you have noticed, such as stains, moss or leaks. That helps a provider give a fairer estimate. When you are ready, send a request and compare what comes back.
