Strip to the deck
The worn layers come off so we can see the wood underneath.
Replace bad decking
Soft, rotted wood at the edge is cut out and replaced with new plywood.
New base and cap
A new base sheet goes down, then a granulated cap sheet on top.
Flat roof repairs we do
- Roll roofing and modified bitumen — splits, blisters, worn spots and open seams.
- Torch down — cracked or lifted seams and worn cap sheet, repaired with the same system.
- Rotted decking — soft wood under the flat section cut out and replaced.
- Porch, patio and room additions — low and flat sections tied into the main roof.
- Flashing, walls and edges — where the flat roof meets a wall or a sloped roof.
- TPO and rubber (EPDM).
Signs your flat roof needs a repair
- Ceiling stains under the flat section
- Water standing for days after rain
- Split or open seams
- Blisters or bubbles in the surface
- Soft spots when you step on it
- Peeling flashing where the roof meets a wall

Flat Roof Repair FAQs
Most flat roof leaks come from one area — a split seam, worn spot or failed flashing. We inspect, photograph it and tell you plainly whether a repair will hold or not.
Most flat sections on Houston homes are roll roofing, modified bitumen or torch down; some are TPO or rubber. We identify it on the inspection and repair it with the same material.
Low spots, clogged drains or edges, or sagging decking. Standing water speeds up wear, so we check the cause, not just the surface.
Yes. Soft or rotted wood under the flat section is cut out and replaced before anything goes back on top.
It depends on the size and what's under the surface. We give you a firm price after the free inspection, before any work starts.
We focus on homes.
