Commercial Roofing Everett WA | TPO, EPDM, Flat Roof

Last updated: 2026-08-30

Roofing Everett WA is a roofing company serving Everett and Snohomish County, and commercial roofing is one of the services we handle most. This page covers what the work involves here specifically — the climate, the code, and what it costs — rather than what it involves in general.

What we do on the first visit

The first visit is an inspection, not a sales call. We walk the roof with you, check the deck from the attic side where we can, count valleys and penetrations, and note the pitch and how much staging or safety equipment the job needs. We confirm whether any prior layers are on the roof already — code allows a maximum of two before a full tear-off is required — and then you get a written per-square price with tear-off and any deck repair as separate lines.

If we think repair is the better spend than replacement, or a different material suits your situation better, we say so on that visit — including when it means the smaller job for us.

What's included

On-site assessment of the existing membrane, drainage, and any ponding-water issues
Written price by system (TPO, EPDM, modified bitumen) before work starts
Full tear-off or overlay, whichever the existing roof's condition actually supports
New flashing and drainage detailing at every penetration and roof edge
A maintenance-program recommendation sized to Everett's waterfront exposure, not a generic schedule
Coordination around business hours to minimize operational disruption

What this costs in Everett

Commercial Roofing runs $24,000–$43,500 typical 3,000 sq ft commercial roof, installed in this area. Reconciled from a Seattle-area contractor-published rate of $8-$14.50/sq ft fully installed for commercial TPO — see the cost guide for the full per-square-foot breakdown. The things that move a job up its range are tear-off, how much deck repair is needed, pitch, and how many valleys and penetrations your roof has. If you want a number before you call, the roof cost calculator will get you close.

When it needs doing

Visible ponding water more than 48 hours after rain
Membrane seams showing separation or blistering
Interior leak stains on a top-floor ceiling
A roof approaching or past its membrane's rated service life

How it works

How commercial roofing runs

Assess the existing roof
We check membrane condition, drainage, and ponding-water history, and confirm whether an overlay is viable or a full tear-off is the honest recommendation.
Written system price
You get a price by roofing system (TPO, EPDM, modified bitumen) before work starts, scheduled around your business hours.
Install
Full tear-off or overlay installed to manufacturer spec, with drainage and flashing detailing addressed at every roof edge and penetration.
Maintenance program
We set up a maintenance schedule sized to your building's actual exposure, since waterfront-adjacent commercial roofs see faster wear than inland buildings.

Questions

Commercial Roofing questions

How much does commercial roof replacement cost in Everett?

A typical 3,000 sq ft commercial roof runs roughly $24,000-$43,500 installed, based on a $8-$14.50/sq ft Seattle-area contractor rate — see our cost guide for the full breakdown and what changes the number.

How often does a commercial flat roof need replacing?

See our dedicated guide — the honest answer depends on membrane type, drainage design, and maintenance history, not a fixed number of years.

Do you offer a maintenance program instead of waiting for a failure?

Yes — a scheduled inspection and maintenance program catches small membrane or drainage issues before they become a leak, and it's cheaper than emergency repair calls.

Do you charge for an estimate?

No. Estimates are free across Everett and Snohomish County, including the drive. We walk the roof with you, check the deck from the attic side where we can, and hand you a written per-square price with tear-off and any deck repair broken out as their own lines.
