Commercial Roofing in Houston

When a commercial roof fails, it doesn't just leak — it shuts down a sales floor, soaks inventory, and puts tenants on the phone. Our commercial crews have been keeping Houston businesses dry since 1985: TPO, EPDM, and modified bitumen systems installed around your operations, not on top of them. Tell us about the building and you'll have a real number by the end of the next business day — guaranteed.

Flat & Low-Slope Systems, Compared Honestly

There is no single "best" commercial roof — there's the right system for your building, budget, and how the roof gets used. Here's how we'd actually explain the options across the table.

TPO — The Houston Workhorse

A white, reflective single-ply membrane with heat-welded seams — the seams are fused into one piece of material, not glued. The reflectivity matters here more than almost anywhere: it knocks down rooftop temperatures and the A/C load under them, which on a Houston warehouse or retail box is real money every summer.

Best for: most Houston flat roofs where energy cost and proven performance matter.

EPDM — Proven Rubber

The black rubber membrane that's been on commercial roofs for 50+ years — a long, boring track record, which on a roof is a compliment. Its dark surface absorbs heat, so it makes the most sense on roofs where reflectivity isn't the priority: shaded or low-visibility roofs, heavily insulated buildings, budget-driven re-covers.

Best for: low-visibility roofs and owners who want decades of known behavior.

Modified Bitumen — Built for Traffic

Asphalt-based rolls installed in multiple redundant plies — if the top layer gets scuffed, there's another waterproof layer under it. That redundancy is the point: on roofs where HVAC techs and equipment traffic are constant, a single-ply membrane takes abuse a mod-bit system shrugs off.

Best for: high-traffic roofs with lots of rooftop equipment and service visits.

Metal Retrofit

If you have an aging metal roof, full tear-off usually isn't the only path. Retrofit options — sealing and coating the existing panels, or framing a new system over them — can add decades without stripping the building open. Which one makes sense depends on how far the fasteners and seams have gone; we'll tell you which after we're on the roof.

Best for: warehouses and shops with existing metal roofs nearing end of life.

Buildings We Roof

Forty years around Houston means our crews have worked just about every kind of commercial roof in the metro.

  • Retail & restaurants — where a leak over the sales floor is a closed register, and work has to happen around customer hours.
  • Office buildings — multi-tenant roofs where the property manager answers to everyone under them, and communication matters as much as workmanship.
  • Warehouses & industrial — big fields of low-slope roof where drainage design and seam quality decide whether inventory stays dry.
  • Multi-family & HOA properties — apartment and condo roofs where boards need documentation, predictable phasing, and a contractor who shows up when they said they would.
  • Churches & community buildings — often a mix of steep and flat sections on one structure, maintained on a congregation's budget, scheduled around services.

If your building type isn't on that list, call anyway — if it has a low-slope roof in Greater Houston, it's work we know. See everywhere we work.

We Work Around Your Business, Not Through It

The question every owner and property manager actually wants answered isn't about membranes — it's "can you do this without shutting me down?" Yes. That's the discipline commercial roofing runs on, and here's what it looks like in practice:

  • Phased sections. We open only what we can close the same day, so no part of your roof is ever exposed overnight — and no single rainstorm can turn a re-roof into an interior claim.
  • Off-hours scheduling. Tear-off and mechanical fastening are loud. We schedule the noisy phases for early mornings, evenings, weekends, or your slow season — whatever your operation needs.
  • Clean, safe sites. Entrances, loading docks, and customer parking stay clear and marked. Debris goes straight to contained disposal, and we run magnets across the grounds daily — a nail in a customer's tire is a liability you shouldn't inherit from your roofer.
  • Documented daily. You get a short written report each day: what was completed, what's next, anything we found. When a tenant, your boss, or your board asks how the roof project is going, you have the answer without climbing a ladder.

Preventive Maintenance: The Cheapest Roof You'll Ever Buy

Here's the honest physics of flat roofs: they don't fail in the middle of the field. They fail at drains, seams, and penetrations — a clogged drain ponding water until it finds a seam, a flashing at an HVAC curb that opened a quarter inch. Which means most five-figure emergency repairs started life as a fifteen-minute fix nobody was up there to see.

That's what our maintenance program is for: semi-annual inspections (spring, before storm season, and fall, after it) with drain and scupper clearing, seam and flashing checks, and photo documentation of the roof's condition every visit. Small findings get fixed on the spot or quoted plainly — before the ceiling tiles tell you about them.

Two side benefits owners care about: most manufacturer warranties require documented maintenance to stay valid, and a photo history of the roof's condition is exactly the evidence that makes a future storm claim clean instead of contested. A maintenance contract is the least expensive thing we sell, and over the life of the roof it's the most valuable.

Commercial Storm Damage & Insurance Claims

Hail and wind hurt membranes differently than shingles — and less visibly. Hail bruises and fractures a membrane without always puncturing it; wind uplift breaks the adhesion or fasteners holding the system down, so the roof looks fine from the parking lot while it's peeling loose in layers. Damage a facilities walk-through misses is exactly what shows up as leaks six months later, after the claim window has gotten complicated.

Commercial claims are also simply bigger and more contested than residential ones. Carriers send engineers, not just adjusters, on large losses — so the documentation has to hold up: core samples where warranted, moisture scans, photographed test squares, dated evidence tied to the storm. That's the standard we document to, and we coordinate directly with your adjuster from inspection through final scope so you're not translating between a carrier and a contractor.

One more thing worth saying out loud: for a business, the roof claim is rarely the whole loss. Interior damage, ruined stock, and interrupted operations may fall under other coverages in your policy, and a properly documented roof loss — established early and tied to the storm date — is the foundation those claims sit on. If a storm has hit your building, get the roof inspected now, before the evidence weathers away. And if what we find doesn't justify a claim, we'll tell you that too, and quote the repair straight.

Restore, Re-Cover, or Replace? An Honest Answer.

A commercial roof is an asset with a service life, and the decision at the end of that life has three honest options — not one. A contractor who only ever quotes tear-off is selling you his biggest ticket, not your best answer.

Restoration coating — when the roof is tired but sound

If the membrane is aging but dry — seams holding, insulation not saturated — a fluid-applied restoration coating can add 10–15 serviceable years at a fraction of replacement cost, and it's typically treated as maintenance rather than a capital expense. It is the right call more often than the industry admits. It is the wrong call over a wet roof, which is why we scan first.

Re-cover — when there's one dry roof up there

Code allows two roof systems on most commercial buildings. One existing roof, dry insulation underneath: a re-cover installs the new membrane over the old, saving tear-off, disposal, and days of exposure. Moisture scans decide eligibility — covering wet insulation just seals the problem in.

Tear-off — when anything less is wasting your money

Two layers already up, saturated insulation, or a deck that needs work: tear-off is the answer, and pretending otherwise costs you the price of the shortcut plus the replacement later. When it's tear-off, we say so, show you the moisture readings that made the call, and phase the work so the building never sits open.

Whichever answer fits your roof, you'll see the evidence behind it — scans, photos, and a plain-English explanation — not just a number on a proposal.

Commercial Roofing Questions, Answered Straight

How long does a TPO roof last in Houston heat?
A properly installed TPO membrane in Houston typically delivers 15–25 years of service — and the spread is mostly about installation and maintenance, not the material. Gulf Coast UV and heat punish shortcuts: seams that were hand-rolled instead of properly heat-welded, or a roof that never gets its drains cleared, will fail early. A quality-welded TPO roof on a maintenance program will reach the top of that range; a neglected one won't. We quote thicker membranes (60 or 80 mil) when the building's use justifies it — and tell you honestly when it doesn't.
Can you work while my business stays open?
Yes — that's how most of our commercial work runs. We phase the roof in sections so nothing is open overnight, schedule the loudest work (tear-off, mechanical fastening) for off-hours or your slow periods, keep entrances, docks, and customer parking clear, and sweep the site with magnets daily. You get a short written report each day covering what was completed and what's next, so you can answer to tenants, staff, or a board without walking the roof yourself.
What's the difference between an NDL warranty and a material-only warranty?
A material-only warranty covers the membrane if it's defective — but the manufacturer only ships you replacement material; the labor to fix the roof is your problem. And most flat-roof failures are workmanship (seams, flashings, penetrations), not defective material. An NDL (No Dollar Limit) warranty is the manufacturer standing behind the whole roof system — labor and materials, no cap — and it's only issued when a manufacturer-credentialed contractor installs the roof and the manufacturer inspects it. If you're comparing bids, ask which warranty each one actually carries; a cheap bid with a material-only warranty is not the same product.
Is ponding water on a flat roof a problem?
Water that drains within about 48 hours of a rain is normal on a low-slope roof. Water still standing after that is ponding, and it matters: it accelerates membrane aging under Houston sun, adds structural load, and most manufacturers exclude ponding areas from warranty coverage. The fix is usually drainage — clearing or adding drains and scuppers, or tapered insulation to move the water — not replacing the whole roof. If ponding is your main symptom, we'll quote the drainage correction, not a re-roof you don't need.
Can you install over my existing roof, or does it have to be torn off?
Code generally allows a maximum of two roof systems on a commercial building — so if there's one roof up there and it's dry, a re-cover is often legal and sensible: it saves tear-off cost, disposal, and days of exposure. But it's only honest over a dry substrate. If moisture scans show wet insulation, covering it traps the water and you pay twice. We scan before we recommend; two layers already up or wet insulation underneath means tear-off, and we'll show you the readings that drove the answer.
