Commercial and Flat Roof Repair and Replacement

We repair and replace flat and low-slope roofs on homes and on commercial buildings of any size. These roofs fail differently than shingle roofs: water sits instead of shedding, so seams, drains and flashing matter most. We inspect, document what we find, and recommend the fix that fits the building.

Common flat roof problems we fix

Ponding water

Low spots that hold water after rain and break down the roof surface.

Seam and flashing failures

Open seams and failed flashing at walls, curbs and penetrations.

Blistering and cracking

Surface damage from Texas heat and UV that lets water in.

Clogged drains and scuppers

Drainage problems that turn a small leak into a big one.

Repair or replace

Some flat roofs need a targeted repair. Others are past saving and need a new roof system. We tell you which, with photos, and price the scope the building actually needs. How flat roof repair works and what flat roof replacement costs.

Questions owners ask us

How long does a flat roof last?

It depends on the system and how well it drains. Regular inspections and fixing ponding early are what extend its life.

Can you work around business hours?

Yes. Tell us what works for your tenants or customers and we will plan around it.

Do you provide documentation for property managers?

Yes. Every inspection includes photos and a written condition summary you can share.

Do you handle insurance claims on commercial roofs?

We document storm damage the same way we do for homes, so you or your adjuster can review it.
