Commercial & Flat Roofing in Jersey Village, TX
Flat and low-slope roofs fail differently from the pitched shingle roofs on the houses around them. There is no gravity assist: water leaves a commercial roof only if the slope, the drains, and the membrane seams all still do their job. Jersey Village Roofing Pros services TPO single-ply, modified bitumen, and built-up roofs on retail units, offices, warehouses, and light industrial buildings across Jersey Village and the wider Houston metro.
Quick Answer: repair, recoat, or replace?
If the insulation under the membrane is still dry, repair or a restoration coating is almost always the right call and costs a fraction of replacement. Once a moisture survey shows saturated insulation across a meaningful share of the roof, coating over it only traps the water — that section needs tearing out.
Flat Roof Systems We Service
TPO Single-Ply
The default on newer Houston-area commercial buildings. Heat-welded seams, reflective white surface. Most failures we find are at seams, penetrations, and mechanical curbs rather than in the open field.
Modified Bitumen
Torch- or cold-applied asphalt sheet in multiple plies. Tough underfoot and forgiving of rooftop traffic, which makes it common where HVAC gets serviced often.
Built-Up (Gravel) Roofs
The older tar-and-gravel assemblies still found across established Houston commercial stock. Repairable for a long time, but blisters and gravel displacement signal the end of the run.
Restoration Coatings
Silicone and acrylic systems applied over a sound, dry existing roof. A genuine 10 to 15 year extension when the substrate qualifies — and a waste of money when it does not.
What Actually Kills Flat Roofs in Houston
Three things, in this order. Ponding water is the first and the most common: a flat roof is built with a designed slope toward drains or scuppers, and when deck deflection, crushed insulation, or a blocked drain removes that slope, water sits. Anything still standing 48 hours after rain counts as ponding, and under Gulf Coast sun it cooks seams and accelerates membrane breakdown.
Penetrations are the second. Every HVAC curb, vent stack, conduit, and drain is a hole in an otherwise continuous waterproof surface, sealed by flashing that ages faster than the field membrane around it. On most commercial leak calls we trace the water to a penetration, not to open roof. The third is foot traffic: service technicians walking the same path to a rooftop unit month after month compress insulation and scuff membrane along a predictable line, which is why walkway pads pay for themselves.

How We Scope Commercial Work
We start on the roof, not in the office. That means a walked survey of the field, seams, terminations, and every penetration, with core cuts or a moisture scan where the history suggests trapped water. The report you get back states plainly which sections are dry and repairable, which are saturated, and what each option costs over a realistic service life — because a coating quoted on a wet roof is the single most expensive mistake a building owner can make here.
Scheduling matters as much as scope on an occupied building. Tear-off is noisy and smells; both can be sequenced outside trading hours for retail and office tenants. We agree that sequence up front, along with access, staging, and how rooftop equipment stays in service during the work.
Frequently Asked Questions
How long does a flat commercial roof last in Houston?
In the Houston climate, a TPO single-ply roof generally runs 15 to 20 years, modified bitumen 12 to 20 years, and an older built-up gravel roof 15 to 25 years. Ultraviolet exposure and standing water are what shorten those ranges locally, which is why drainage correction usually adds more service life than any other single repair.
Can a flat roof be coated instead of replaced?
Often, yes. If the insulation below the membrane is dry and the deck is sound, a silicone or acrylic restoration coating can extend service life by roughly 10 to 15 years at a fraction of replacement cost. If a moisture survey finds saturated insulation, coating over it simply seals the water in and the section has to be torn out.
Why does water pond on my flat roof after rain?
Flat roofs are not truly flat; they are built with a slight slope to internal drains or scuppers. Ponding means that slope has been lost, usually through deck deflection, crushed insulation, or a blocked drain. Water remaining more than 48 hours after rainfall is the industry threshold for ponding, and it accelerates membrane failure in Houston's heat.
Do you work around business hours?
Yes. Most commercial flat roof work in the Houston metro can be sequenced around trading hours, and noisy or disruptive phases such as tear-off can be scheduled early, after close, or at weekends. We agree the sequence before work starts so tenants and staff know what to expect.
