By system
What Fails, and How It Gets Repaired
Each system fails in its own way. Knowing which one you have decides the repair, and a contractor who treats them all the same is guessing.
TPO & PVC
Single-ply membrane
Fails at: seams, penetrations, and punctures from foot traffic or dropped tools
Heat-welded patches on TPO, chemically welded on PVC, matched to the existing membrane thickness. Seam probes to find where the weld has released rather than patching what is visible.
EPDM
Rubber membrane
Fails at: seam adhesive, shrinkage at the perimeter, and flashing details
EPDM shrinks as it ages, which pulls at the corners and the curbs before anything shows in the field. Repaired with matched membrane and seam tape, not roof cement.
Mod-bit
Modified bitumen
Fails at: laps, blisters, and the granule surface losing its coating
Torch or cold-applied depending on the original system and what is safe on that building. Blisters are cut, dried and re-lapped rather than covered over.
BUR
Built-up roofing
Fails at: alligatoring, gravel displacement, and flashing at the wall
Older BUR systems are often better than they look. We assess whether a targeted repair still makes sense or whether the ply count is past it — and we will say when it is.
Metal
Standing seam & R-panel
Fails at: fasteners, seams, and the penetrations added after installation
Backed-out fasteners and failed washers are the most common commercial metal leak, and the cheapest to fix. Usually the whole repair.
Any system
Flashing, curbs & details
Fails at: HVAC curbs, drains, scuppers, parapet walls and pipe penetrations
Most commercial leaks are not in the field of the roof at all — they are at something that goes through it. Every unit added after the roof went on is a potential entry point.

One thing we do not do
Government and public-sector buildings. Not at present. Public work brings bonding, prevailing-wage and procurement requirements that are a different business from ours, and we would rather say so than take the meeting.
If you are procuring for a municipality or a school district, we are not your contractor — and we would rather you found that out here than after an RFP.
Diagnosis
The Stain Is Rarely Below the Failure
On a flat commercial roof this is worse than on a house. Water enters at one point, runs across the deck or along a joist, and drops through wherever it finds a gap — often the length of a suite away from where it came in.
Above a suspended ceiling it can travel further still, and the tile that finally gives way tells you almost nothing about where to look.
Which is why we scan rather than patch. Thermal imaging finds saturated insulation, a moisture meter confirms it is water, and a core sample shows what the layers are doing where nothing else can reach. The full toolkit.

Seven Things That Cannot Wait
Answered 24 hours a day, every day. Typical response 2 to 4 hours — longer after a major storm, when every roofer in the city is triaging. Houston's commercial roof repair contractor.
Water entering the building
Anything active. Say which unit or suite when you call.
Storm or wind damage
Membrane lifted, flashing peeled back, or sections missing.
Punctured membrane
Dropped tools, foot traffic, or contractor damage during other work.
Major flashing failure
At a parapet, curb or wall, where water gets behind and stays.
Ponding near drains or equipment
Standing water plus weight is how decks fail.
Interior ceiling damage
Sagging tiles or wet insulation above an occupied space.
Debris or equipment impact
Anything dropped, blown, or craned onto the roof.
Tarped and stabilized first, repaired properly after. Sealant does not bond to a wet membrane, so a permanent repair made in the rain fails within months. On an occupied commercial building the priority is stopping the water and protecting what is underneath — the repair follows when the roof is dry.

The decision
Repair, Restore, or Replace
On a commercial roof there is a genuine middle option, and a contractor who only ever recommends the third one is not assessing your building.
Targeted
Repair
When the roof is sound and the failure is local
- Membrane in reasonable condition overall
- Leaks traceable to specific points
- Insulation dry outside the affected area
- Years of service life remaining
Lowest cost, shortest disruption. Usually the right answer more often than building owners are told.
The middle option
Restoration coating
When the roof is tired but structurally sound
- Widespread surface wear rather than point failures
- Deck and insulation still dry
- Seams repairable before coating
- You want to defer a capital expense
A fraction of replacement cost, no tear-off, and the building stays operational. Can add ten years or more to a system that would otherwise be replaced.
Capital
Replacement
When the system is genuinely finished
- Saturated insulation across large areas
- Deck deterioration
- Repeated failures in different locations
- Repair spend approaching replacement cost
The right answer sometimes. We will tell you when, with the thermal scans and moisture readings that show why.
How we decide, and how you can check us. The scan shows how much of the insulation is wet and where. If saturation is localized, it is a repair. If it is across the roof but the deck is sound, restoration is usually the better economics. If the deck is going, no coating will save it.
You get the thermal images and the moisture readings either way. Take them to another contractor if you want a second opinion — that is what they are for. Houston's commercial roof repair contractor.
The process
Five Steps, Documented at Both Ends
-
Free commercial inspection
Full roof survey with thermal imaging and moisture readings, drone where the roof cannot be safely walked, and every detail photographed — curbs, drains, penetrations, perimeter.
-
Diagnosis and condition report
What is wrong, where, and the probable cause — stated rather than implied. With the scans attached, so the finding can be checked rather than taken on trust.
-
Itemized proposal
Scope, materials by name, and what is excluded. Where repair and restoration are both viable you get both priced, with our view of which makes more sense and why.
-
The work
Scheduled around your operating hours where that is possible. Tenants and access considered before we arrive rather than after.
-
Completion documentation
What was done, what was used, photographs of the whole job, and anything left outstanding stated plainly. In a form you can forward without editing.
Common questions
Commercial Roof Repair Questions
How fast can you get to a commercial building?
Typically 2 to 4 hours, 24 hours a day, every day of the year. After a major storm that stretches for everyone.
Active water intrusion is prioritized. Tell us which unit or suite when you call — on a multi-tenant building that decides where we start.
Can you work around our operating hours?
Usually, yes. Retail, medical and food service all have hours when roof work is disruptive, and we would rather schedule around them than argue about it afterward.
Tell us the constraints when you call and they go into the proposal rather than being discovered on day one.
Do you handle the insurance claim?
No. Filing, negotiating and settling a claim is the work of a licensed public adjuster, and in Texas a roofing contractor cannot do it.
What we do is document the damage thoroughly and meet the adjuster on the roof so both parties assess the same evidence. How Texas claims work.
Is ponding water actually a problem?
Yes. Water still standing 48 hours after rain is a defect. It adds weight, degrades the membrane beneath it, and most manufacturer warranties exclude damage caused by it — which is worth knowing before you make a warranty claim.
The cause is usually a blocked drain, a settled deck or rooftop equipment installed without regard for drainage. All three are fixable.
Should we repair, coat, or replace?
The thermal scan decides it. Localized saturation is a repair. Widespread surface wear with a dry deck is usually better economics as a restoration coating. A deteriorating deck cannot be saved by any coating.
You get the scans and the moisture readings either way, so the recommendation can be checked rather than taken on trust.
Do you work on government buildings?
Not at present. Public-sector work brings bonding, prevailing-wage and procurement requirements that are a different business from ours.
If you are procuring for a municipality or a school district, we are not your contractor — and we would rather tell you here than after an RFP.
What documentation do we get?
A condition report with thermal images and moisture readings before, an itemized proposal, a photo record of the whole job, and completion documentation stating what was done and anything left outstanding.
Written so you can forward it to an owner or an asset manager without editing it first.
