Most roofers won't tell you what a roof costs until they're sitting at your kitchen table. We'd rather show you. Each price above is the full contract total (plus tax), including the repairs and upgrades that house needed, not just the roofing material.
Your price will depend on the size and pitch of your roof, access, the material you pick, and what we find under the old roof. For a standard asphalt shingle roof, our base is $9.42 per sq ft, about $23,500 for a 2,500 sq ft roof before add-ons, plus tax. That base comes from 569 average RoofSmart jobs in the last 12 months, with outliers left out.
The SmartMatch visit is free when there's no active leak. If your roof is leaking now, a repair visit is $475.

We follow Auburn's rules and pull permits as needed. Every job is different.
| Job | Auburn rule |
|---|---|
| Like-for-like reroof | Permit-exempt when the new roofing replaces the old like for like, no extra load goes on the roof and no structural members are altered. |
| Added load or framing changes | Not covered by that exemption. The City lists reroofing among projects that may need a permit and asks you to check with its Permit Center first. |
Exempt work still has to meet code. Homes outside Auburn city limits follow county permit rules.

| Number | What it means |
|---|---|
| 40.09 in | Average yearly precipitation at NOAA's nearby Kent station. About 75% falls October through March, and November is wettest at 6.23 in. |
| About 153 days | Days a year with measurable rain at the Kent station, so wet roof work is the norm here. |
Moss is a western Washington fact of life.
WSU Extension says our cool, damp climate favors it, it grows mostly in fall, winter and spring, and left alone it shortens roof life.
Moss can work under shingle edges and loosen them, worst on cedar. Skip the pressure washer.

1. SmartMatch first. We diagnose the roof and attic, talk through your goals, then recommend. If you don't need a new roof, we say so.
2. Clean-deck install. Every old layer comes off. Our own crew does the work, about 3 days on site on average.
3. TripleGuard™. Lifetime workmanship and lifetime material coverage on eligible roofs, plus a promise the work meets code.
If the cheapest bid is the goal, we're not your roofer. TripleGuard covers roofs built to our expert design. We can't warranty a budget build.

For a firm price, book a SmartMatch inspection. The SmartMatch visit is free when there's no active leak. If your roof is leaking now, a repair visit is $475.
You can also call (206) 487-4877.
A free SmartMatch inspection tells you whether to repair, replace or monitor your roof.
The visit takes 60 to 90 minutes, usually about 1 week after you ask, and you get a plain-English findings sheet.
If you don't need a new roof, we say so. With an active leak, start with a $475 repair visit.
A RoofSmart repair visit starts at $475, which covers a two-person crew's first hour on your roof.
After that it's $125 per worker per hour, plus materials.

RoofSmart follows Auburn's rules and pulls permits as needed. Every job is different.
Inside city limits, Auburn City Code 15.08A.025 exempts like-for-like replacement of residential roofing from a building permit when no additional load is applied and no structural members are altered.
Work that adds load or changes the framing isn't covered by that exemption. Exempt work still has to meet code, and homes outside city limits follow county rules.
No. RoofSmart removes every existing layer, because manufacturers require a clean-deck install.
We tear off to the deck on every replacement.
A RoofSmart roof replacement takes about 3 days on site on average: tear-off, new roof and finish.
The full process typically runs 3 to 4 weeks, including 1 to 2 weeks of scheduling and prep. That holds for metal roofs too.
Yes, a shingle roof can be replaced in the rainy season when the rain is light, but crews stop for heavy downpours.
We tear off in small sections and seal the deck as we go. Expect a winter job to take 10 to 20% longer.
Flat roofs need a full tent, so they usually wait for dry weather unless there's an active leak.
The right roof for your Auburn home depends on what we find on your roof first, and then on your budget and how long you plan to stay.
Asphalt shingles cost less up front, and we install GAF, CertainTeed and Owens Corning.
Standing seam metal costs more. All three Auburn jobs on this page are CertainTeed asphalt shingle roofs.
We also install flat membranes: PVC, TPO, torchdown and Duradek.
Moss is maintenance, and no roof warranty covers moss removal, "any more than car washes are included with your car warranty."
WSU Extension says western Washington's cool, damp climate favors moss, which grows mostly in fall, winter and spring.
Moss can work under shingle edges. Don't pressure-wash it off.
Eligible RoofSmart roofs are covered by TripleGuard™: lifetime workmanship and lifetime material coverage, plus our promise that the work meets code.
TripleGuard covers roofs built to our expert design. We can't warranty a budget build. Moss, acts of God and other contractors' work aren't covered.
All three Auburn roofs on this page are covered by TripleGuard.
