Home Service Commercial Flat Roofing (TPO, EPDM, PVC)

Commercial Flat Roofing

Houston’s humidity, ponding rain, and summer heat break down low-slope roofs faster than almost anywhere else in Texas.

Our licensed commercial flat roofing crews install and repair TPO, EPDM, and PVC membrane systems engineered to handle Houston’s climate and keep your building watertight.

Membrane selection and installation quality determine how long a flat roof survives a Houston summer.

Signs Your Commercial Flat Roofing Needs Attention

Ponding Water Past 48 Hours

Standing water that hasn't drained two days after Houston rainfall accelerates membrane breakdown and signals a slope or drainage problem.

Blistering or Membrane Seams Lifting

Trapped moisture under TPO or EPDM expands in the heat, causing bubbles and lifted seams that let water reach the insulation below.

Interior Ceiling Stains Near HVAC Curbs

Roof penetrations around rooftop units and drains are the most common leak points on Houston commercial buildings.

How We Choose the Right Membrane

Why TPO, EPDM, and PVC Perform Differently on Houston Roofs

✔ TPO reflects heat and resists Houston’s UV exposure, lowering rooftop surface temperatures
✔ EPDM handles ponding water and thermal movement well on older low-slope buildings
✔ PVC resists grease and chemical exposure, common on restaurant and industrial roofs

We inspect your building’s slope, drainage, HVAC load, and prior roofing history before recommending a system, rather than defaulting to one membrane for every property.

Emergency Commercial Flat Roofing Repair

What to Do When a Storm Damages Your Flat Roof

Gulf Coast storms and hail don’t wait for business hours. A compromised membrane on a flat roof can flood a building’s interior within hours if left unaddressed.

✅ Same-day emergency response to active leaks and storm damage
✅ Temporary membrane patching and tarping to stop water intrusion
✅ Documentation and photos prepared for your insurance adjuster

Protecting Your Building's Value

How a Properly Installed Flat Roof Lowers Your Operating Costs

✔ Licensed, bonded, and insured commercial flat roofing crews
✔ Locally based and familiar with City of Houston permitting and inspection requirements
✔ Reflective membrane options that can reduce cooling loads during Houston’s peak summer months

Common Questions About: Commercial Flat Roofing (TPO, EPDM, PVC)

How long does a commercial flat roof last in Houston’s climate?

For commercial flat roofing, TPO and PVC membranes typically last 20–25 years, while EPDM systems often reach 20–30 years, though Houston’s UV intensity and humidity tend to shorten these ranges compared to drier climates. Regular inspections and prompt seam repairs are the biggest factors in reaching the upper end of that lifespan.

What causes ponding water on commercial flat roofing?

Ponding usually results from inadequate roof slope, clogged or undersized drains, or structural settling over time. In Houston, heavy rainfall events make drainage design especially important; ponding left unaddressed for more than 48 hours accelerates membrane degradation.

Is TPO or EPDM better for a Houston commercial building?

TPO’s reflective white surface helps reduce rooftop heat gain during Houston summers, which can lower cooling costs, while EPDM tends to perform well on roofs with existing ponding issues or irregular drainage. The right choice depends on your building’s slope, HVAC load, and roofing history.

Do I need a permit to replace a commercial flat roof in Houston?

Most commercial roof replacements in Houston require a permit through the City of Houston Permitting Center, particularly when work involves structural decking or exceeds a defined percentage of the existing roof area. We handle permit applications and coordinate required inspections as part of the project.

How long does a commercial flat roofing installation take?

We recommend two inspections per year for Houston commercial properties — once before hurricane season in late spring and once in early fall — plus an additional check after any major hail or wind event.

Can a flat roof be repaired instead of fully replaced?

Localized membrane damage, seam failures, and isolated punctures can often be repaired without a full replacement, provided the underlying insulation and decking are still sound. We assess the roof’s overall condition before recommending repair versus replacement.

What roofing materials hold up best against Houston hailstorms?

Reinforced TPO and PVC membranes with impact-resistant backing generally withstand hail better than unreinforced EPDM. Membrane thickness (measured in mils) also affects hail resistance; thicker membranes typically show fewer punctures after storm events.

Will a new commercial roof reduce my energy costs?

A reflective TPO or PVC membrane can lower rooftop surface temperatures significantly compared to older, darker roofing materials, which may reduce HVAC run time during Houston’s extended cooling season. Actual savings depend on your building’s insulation, HVAC efficiency, and roof size.

How long does a commercial flat roof installation take?

Most Houston commercial flat roof installations take between one and three weeks, depending on square footage, weather delays, and whether the existing roof requires tear-off versus a recover system.

What should I do immediately after storm damage to a flat roof?

Document visible damage with photos, avoid walking on the roof if structural damage is suspected, and request emergency tarping to prevent water intrusion. We provide same-day tarping and prepare documentation for insurance claims on Houston commercial properties.

Does insurance typically cover commercial flat roofing repairs in Houston?

Storm and hail-related damage is commonly covered under commercial property policies, though coverage depends on your specific policy and the roof’s documented condition prior to the event. We provide inspection reports and photo documentation that adjusters typically request.

What warranty comes with a new commercial flat roof?

Workmanship warranties on our commercial flat roof installations run up to 5 years, in addition to manufacturer material warranties on the TPO, EPDM, or PVC membrane itself, which vary by product line.
