Flat Roof Repair in Mobile
Flat roof repair in Mobile means finding the detail that failed on a flat or low-slope roof, checking the membrane around it, and repairing it with materials compatible with that membrane.
A flat roof does not shed water the way a pitched roof does, so a single open seam or a loose flashing lets water sit and work its way in. On homes and commercial buildings alike, we fix that spot in the roof's own system, instead of spreading a patch over it that does not belong to the roof.
Flat Roof Systems We Repair
These are the flat roof systems we repair, and the membrane already on your roof sets what goes into the fix:
- Built-up roofing
- Modified bitumen
- TPO membrane
- PVC membrane
- EPDM rubber roof
- Fluid-applied coatings
"Built-up roofing" is the hot mop or tar and gravel roof: layers of base sheet and inner ply finished with a cap sheet or rock. TPO, PVC and EPDM are the single-ply sheets people call a rubber roof or a white flat roof.
How Flat Roof Repair Is Priced
Flat roof repair is priced by the area and the system, and a targeted ponding fix or a coating costs less than a tear-off where the roof allows it. In Mobile, flat roof repair typically runs
$1,141.07 to $2,282.13 a repair, or about $16.30 per square foot
The size of the damage, the materials and the access move it, and water that has gone deeper into the roof raises it. The exact price comes from the free estimate, in writing, before we start.

The failed seam, flashing or low spot, repaired where it sits.
- Open seams and lifted edges

-
Over a sound roof

A fluid-applied coat that seals a worn membrane that is still sound.
- Worn but sound membrane
- Seals the whole surface
- Can cost less than a tear-off
-
When the membrane is done
Tear-off
The old roofing stripped down to the roof deck, the largest job here.
- Down to the roof deck
- Rotted deck wood replaced
- Priced by area and system
Finding the Failed Detail
We start a low-slope leak check at the edge metal and base flashing, then inspect the surrounding membrane before the repair, in these four steps:
-
Edge metal and base flashing first
Wind works a membrane loose at the roof edge and where it turns up a wall, so that is where the leak check begins.
-
The membrane around it
Next we inspect the surrounding membrane for open seams, low spots that hold water and "alligatoring", the crazed cracking of an aged surface.
-
The drains and scuppers
"Scuppers", the drain openings in the wall, clog with windblown debris, and a clogged drain leaves water sitting on the seams.
-
A repair that matches the roof
Once you have the price in writing and have said yes, we repair the failed detail with materials compatible with your membrane.
Ponding and Drainage
Water still standing on a flat roof 48 hours after the rain stops means the roof has a drainage problem, and that standing water, "ponding" in the trade, puts even a sound seam at risk of failing.
48 hoursStill wet by then? Call us for a free estimate before that water opens a seam.
Puddles that are gone by the next day are normal on a low-slope roof. The ones that stay sit right on the seams and the flashing, and a clogged scupper or a low spot in the roof is where we look first. The National Roofing Contractors Association roofing manual is the industry reference for the slope minimums and details a low-slope roof is built to.

Coating a Flat Roof
A coating seals a worn flat roof and extends its life, as long as the membrane under it is still sound. On a flat roof, a coating can also cost less than a tear-off or a full replacement.

Flat roof questions
What is best to repair a flat roof?
The best repair uses materials compatible with the membrane already on the roof, at the detail that actually failed. Built-up roofing, modified bitumen, TPO, PVC and EPDM each take their own kind of repair, so we find the failed seam or flashing first and match the fix to the system.
How much does it cost to have a flat roof repair?
In Mobile, flat roof repair typically runs $1,141.07 to $2,282.13 a repair, or about $16.30 per square foot. The area, the system, the size of the damage and the access set where yours lands, and a targeted ponding fix or a coating costs less than a tear-off where the roof allows it. We put the exact price in writing after a free estimate, and our roof repair cost guide walks through what moves the price.
How do you repair a flat roof?
We start at the edge metal and the base flashing, where wind works a membrane loose, then inspect the surrounding membrane to find the detail that failed. The repair goes down in materials compatible with that membrane, after you have the price in writing.
