We also inspect rooftop HVAC curbs and penetrations, since equipment mounts are a common overlooked source of flat roof leaks.


A flat roof leak rarely shows up directly above where the water actually entered — membrane systems move water laterally before it drips through.
Commercial Flat Roof Repair scheduling is built around minimizing disruption to your Chinook business operations.
Every Flat Roof Repair technician carries current Chinook, WA licensing for commercial roofing work.
We coordinate Chinook scheduling around your business hours whenever the situation allows.
No surprise costs once we're already on the roof mid-repair.
Proper membrane welding equipment prevents the seam failures common with improvised patches.
Here's what falls under our Chinook Flat Roof Repair service for commercial and low-slope roofs.
TPO seam separation gets properly heat-welded, not just caulked over as a temporary fix.
We identify the membrane type first, since EPDM and TPO repairs use different adhesive systems.
Standing water that doesn't drain within 48 hours accelerates membrane breakdown and needs a drainage fix, not just a patch.
Modified bitumen blisters and seam issues are repaired using proper torch-down or cold-adhesive technique depending on the situation.
We clear and repair drains and scuppers as part of a full Flat Roof Repair visit.
Rooftop HVAC units and their curbs are a frequent source of Chinook commercial roof leaks that general roofers often overlook.

We start by discussing the issue — ponding, active leak, or visible membrane damage.
A technician inspects the membrane system, checking seams, drains, and any ponding areas.
Repair scope and pricing are explained clearly so you can plan around business operations.
Repaired seams are tested for a proper bond before we leave the site.
