What does flat roof repair involve?
We locate the entry point, dry the area, and repair or replace the failed membrane, coating, or flashing detail. Drains and scuppers get cleared so water has somewhere to go. Blisters and soft spots are opened and rebuilt when needed.
When do you need flat roof repair?
- Water ponds for days after rain.
- Ceiling stains sit under a patio cover or rear addition.
- Seams are open, cracked, or alligatored from sun.
- A prior coating is peeling in sheets.
Why flat roofs struggle in this climate?
UV destroys exposed coatings. Infrequent but hard rains overload clogged drains. Heat softens some materials so foot traffic leaves dents that hold water. Washington additions from past decades often used whatever membrane was cheap at the time — and those systems are aging out together.
What affects flat roof repair cost?
- Area of failure versus full resurfacing
- Drain and flashing rebuilds
- Moisture already in the deck
- Access and parapet height
Repair versus recoating the whole low-slope
A local seam repair is enough when the field is sound. When the membrane is brittle everywhere, a larger resurfacing or replacement is the honest path. We show you both and price them clearly.
Flat roof repair FAQs
Can you fix a plywood patio cover roof?
Yes, many patio covers are low-slope systems we repair or re-cover. Soft framing changes the plan, and we tell you if structure is the real issue.
Do you use torch-down or coatings?
We match the method to the existing system and the failure mode. The estimate names the approach before we start.
Will ponding go away after a repair?
If structure creates a low spot, a surface patch will not create new slope. We discuss drainage options when ponding is built into the framing.
