Roof Repair and Maintenance in Portland and Vancouver
Residential and Commercial. Serving Portland, Beaverton, Hillsboro, Gresham, Lake Oswego, Vancouver WA, and surrounding areas.
Your roof is roughly 30 percent of your building envelope and protects 100 percent of what is inside. Flow Roofing provides permanent roof repairs and preventative maintenance for homes and commercial properties across the Pacific Northwest. For commercial owners and property managers, we specialize in TPO, PVC, modified bitumen, and torch down flat roof systems, the systems most commonly found on local commercial and multi family buildings.
Professional Roof Repair and Maintenance
We deliver expert repair and maintenance for residential and commercial roofs. From minor repairs to full system diagnostics, our team identifies issues early and provides permanent solutions designed for heavy rain, sustained moisture, and seasonal wear.
Preventative Roof Maintenance
Preventative maintenance is one of the most effective ways to extend the life of a roof in this climate. Frequent rain, moss growth, and moisture exposure mean small issues turn into expensive ones quickly. Our maintenance programs catch problems early, protect your roofing system, and reduce long term costs.
​
For commercial buildings, HOAs, and multi family properties, preventative maintenance matters even more. A neglected flat roof during the wet season can cause tenant displacement, business interruption, and liability exposure. Our commercial maintenance programs include biannual inspections, written condition reports, seam and flashing checks, drain clearing, and membrane assessments for TPO, PVC, and modified bitumen systems.
Roof Maintenance Audits and Inspections
We perform detailed inspections and maintenance audits to evaluate the condition of your roofing system. You receive a clear written assessment of your roof's current state with recommendations for repair, maintenance, or replacement.
Where We Work

Our Process
If you need a roof repair in Portland, Oregon, our process is simple, clear, and built around your schedule.

DISCUSS
YOUR NEEDS

Trusted by Homeowners, Property Managers, and Commercial Clients
We are committed to high quality workmanship, clear communication, and long lasting roofing solutions built for the Pacific Northwest.
Commercial Roof Repair
We provide commercial roof repair for office buildings, retail properties, warehouses, industrial facilities, HOAs, and multi family properties. Commercial roofing systems require specialized knowledge. A TPO seam failure, a PVC membrane blister, or a torch down delamination is not the same as a residential shingle repair, and the wrong fix can void your manufacturer warranty.
Our commercial repair team diagnoses the root cause of every leak before recommending a solution.
Common commercial repairs include:
-
TPO and PVC membrane seam repairs and re welding
-
Modified bitumen and torch down patch repairs
-
Flashing replacement around HVAC units, skylights, and penetrations
-
Drain and scupper clearing and repair
-
Ponding water corrections and tapered insulation installation
-
Emergency tarping and temporary weatherproofing
​
Most commercial roof repairs in our area fall between $500 and $8,000 depending on the system, the extent of damage, and roof access. Some scopes fall outside that range in either direction. We provide a written estimate with no obligation after a free inspection. Call 503-936-2476.
