Flat Roofing in Texas Built for Heat, Hail, and Hard Rain

TPO, EPDM, and modified bitumen systems installed statewide by crews who know Texas weather


Flat Roofing in Texas is not the same job it is in cooler states. Between 100-degree summers, golf-ball hail, and Gulf humidity, a flat roof takes a beating that shingle roofs never see. We install and replace TPO, EPDM, and modified bitumen systems for homes, shops, and commercial buildings across the state, and we back every flat roof installation in Texas with a written workmanship warranty.

What Our Flat Roofing Service Includes

Every flat roof project starts with a free inspection and a written scope. Here is what is covered on a standard installation or replacement. Anything outside this list, like structural deck repair or added rooftop equipment, gets priced separately and approved by you before we start.

Free Roof Inspection

We walk the roof, core-test the deck, and scan for wet insulation with a moisture meter and infrared camera. You get photos and a written report within 24 hours. No charge, no obligation.

Tear-Off and Disposal

We remove the old membrane, flashing, and wet insulation, then haul everything off-site. Dumpsters are placed so they do not block your driveway or loading dock. A 2,000-square-foot tear-off takes one to two days.

New Membrane System

We install TPO, EPDM, or modified bitumen over new insulation and cover board. Seams are heat-welded or adhered to manufacturer spec. Membrane thickness ranges from 45-mil to 80-mil depending on traffic and warranty needs.

Flashing and Drainage

Every penetration, curb, edge, and scupper gets new flashing and sealant. We set tapered insulation to move water toward drains. This is the step that prevents ponding water on flat roofs and the leaks that follow.

Warranty and Walkthrough

We flood-test the drains, walk the roof with you, and hand over the manufacturer material warranty plus our written workmanship warranty. You get a maintenance checklist and our direct line for any future issues.

What Flat Roofing in Texas Actually Involves


Flat Roofing in Texas means installing a low-slope membrane system that sheds water across a nearly level deck instead of down a pitched plane. That usually means a TPO membrane, an EPDM membrane, or a modified bitumen cap sheet over a clean substrate, with tapered insulation to move water toward drains and scuppers. We mechanically fasten or fully adhere the membrane, heat-weld the seams, and detail every penetration, curb, and edge with flashing and sealant so nothing weeps during a two-inch rain event.

Most Texas flat roofs fail for three reasons: ponding water on flat roofs, UV breakdown from relentless sun, and flashing failure at parapet walls. A moisture meter and infrared camera tell us how far the wet insulation spreads before we quote anything. If you are searching for flat roofing installation in Texas near me because a ceiling stain showed up after last spring's storms, we can usually get an inspector on your roof within 24 to 48 hours.

How Our Flat Roof Installation Process Runs

Every job follows the same five steps, whether it is a 400-square-foot garage in Belton or a 40,000-square-foot warehouse in Odessa. You always know what happens next.

01

Schedule

Call or book online — a real human picks up and confirms a 2-hour arrival window.

02

Diagnose

Licensed tech inspects on-site, then walks you through the cause and your options.

03

Fix

The job is completed to code and done right the first time — no shortcuts, no surprises.

04

Guarantee

Every job backed by a written workmanship warranty — and we stand behind it.

Tools and Methods We Use on Flat Roofs

Tools & Equipment

Infrared Camera

Detects wet insulation under the membrane by reading temperature differences. It lets us map the full extent of water damage before we quote, so you are not paying to replace dry material.

Moisture Meter

Confirms what the infrared camera finds. We take readings at grid points across the deck and core-test any suspect areas. This is how we decide between a repair and a full replacement.

Roofing Nail Gun and Hammer

Used for fastening cover board, insulation, and edge metal. We set fasteners to manufacturer spec so they do not back out or crush the substrate over time.

Heat Welder

Bonds TPO seams into a single continuous membrane. A properly heat-welded seam is stronger than the membrane itself. We probe-test every seam before the job is signed off.

Safety Harness and Roofing Ladder

Keeps crews safe on steep access points and roof edges. Every job is OSHA-compliant, and we set up fall protection before anyone steps on the deck.

Tarp

Covers the roof overnight during tear-off and after storm damage. We tarp every evening so a surprise Texas thunderstorm never gets inside your building.

Methods & Standards

TPO Heat-Welded Membrane System

We roll out 60-mil or 80-mil TPO, heat-weld the seams, and detail every penetration and edge. TPO reflects heat, resists UV, and handles Texas temperature swings. It is our most common spec for commercial and residential flat roofs.

EPDM Fully Adhered System

EPDM membrane is glued to the substrate with contact adhesive, creating a seamless rubber surface. It performs well on residential flat roofs and low-traffic decks. We use Firestone and Carlisle SynTec EPDM for the longest warranty terms.

Modified Bitumen Cap Sheet

A torch-applied or self-adhered asphalt cap sheet over a base layer. It works well on small porches, additions, and low-slope sections where TPO is overkill. We use GAF and CertainTeed products with granulated surfaces for UV protection.

Tapered Insulation for Drainage

We set polyiso insulation in graduated thicknesses to build slope toward drains and scuppers. This is the permanent fix for ponding water on flat roofs. Without it, no membrane will last its full warranty period.

HAAG-Certified Storm Documentation

Our inspectors are HAAG-certified to assess hail and wind damage. We photograph every impact, core-test the deck, and write a report that meets Texas Department of Insurance standards. That documentation is what gets claims approved.

When Texas Property Owners Need Flat Roofing

01

A homeowner in Bellaire has a flat roof over a garage or addition that has started leaking into the wall.

What we do: We inspect the deck, replace any wet insulation, and install a new EPDM or TPO membrane with fresh flashing at the wall tie-in. Most residential flat roof replacements finish in two to three days.

→ A dry garage, a written warranty, and a maintenance schedule that keeps the roof serviceable for 20-plus years.

02

A commercial property manager in Odessa needs a 20,000-square-foot warehouse roof replaced before the next rainy season.

What we do: We phase the tear-off so the building stays dry, install tapered insulation and a 60-mil TPO membrane, and coordinate around tenant schedules. Commercial replacements typically run one to three weeks depending on size.

→ A code-compliant roof with a 20-year material warranty and no disruption to daily operations.

03

A restaurant owner in Beaumont has ponding water on a low-slope roof and a ceiling stain spreading over the dining room.

What we do: We trace the leak with a moisture meter and infrared camera, repair the flashing and drainage, and add slope where needed. Same-day emergency tarp service is available if the leak is active.

→ The leak stops, the ceiling dries out, and the fix costs a fraction of a full replacement.

04

A church in Belton needs a flat roof inspection before filing an insurance claim for hail damage.

What we do: Our HAAG-certified inspector documents every impact, core-tests the deck, and writes a report the adjuster can use. We handle the repair or replacement once the claim is approved.

→ A fully documented claim, a properly repaired roof, and no out-of-pocket surprises beyond the deductible.

How Flat Roofing Runs Across Texas

Texas flat roofs face conditions that crews in cooler states never deal with. Summer surface temps on a dark membrane hit 160 to 180 degrees. Spring hail in North Texas and the Panhandle dents metal and bruises TPO. Gulf humidity in Beaumont, Port Arthur, and Angleton keeps decks wet and accelerates algae growth. We spec every job for its region: reflective white TPO in West Texas, fully adhered EPDM near the coast, and reinforced flashing details in hail alley. Building codes vary too. Some Texas jurisdictions follow the 2021 IBC, others still enforce older editions, and wind-borne debris requirements change by county. We pull permits and schedule inspections so you are not chasing paperwork. If you need flat roofing in Texas cost numbers for a specific city, our inspector will give you a written range after the free roof scan, usually within 24 hours.

Neighborhoods We Serve

  • Del Valle

    New industrial and warehouse construction along the SH-71 corridor means a lot of large low-slope decks that need TPO systems and proper drainage design.

  • Bellaire

    Older homes with flat roof additions and garages are common here. Many have original modified bitumen that is past its service life and ready for EPDM replacement.

  • Beaumont

    Gulf humidity and heavy rain make flashing failure and ponding water the two most common calls we get in this area.

  • Odessa

    Permian Basin heat and wind load demand reflective membranes and mechanically fastened systems rated for high wind zones.

  • Belton

    Hail season in Central Texas hits hard here. We see a lot of bruised TPO and cracked modified bitumen after spring storms.

Local Conditions We Plan For

  • Summer surface temperatures of 160 to 180 degrees on dark membranes

    Accelerates UV breakdown and shortens membrane life. We spec reflective white TPO or UV-resistant coatings to bring surface temps down 30 to 50 degrees.

  • Spring hail in North Texas and the Panhandle

    Bruises TPO, cracks modified bitumen, and dents metal flashing. We document every impact with HAAG-certified reports so insurance claims cover the full repair.

  • Gulf humidity and salt air along the coast

    Promotes algae growth and corrodes fasteners. We use corrosion-resistant fasteners and algae-resistant membranes in Beaumont, Port Arthur, and Angleton.

  • Expansive clay soils across much of the state

    Causes deck movement that opens seams and flashing joints over time. We use reinforced termination details and flexible sealants that move with the structure.

Odessa Warehouse Ponding Water Fix

Before

A 12,000-square-foot warehouse roof had standing water 72 hours after every rain. The existing membrane was 14 years old, seams were separating, and two ceiling leaks had already damaged stored inventory.

After

We tore off the old system, added tapered insulation to build slope, and installed a new 60-mil TPO membrane with heat-welded seams. Water now drains within 24 hours of a storm, and the building has stayed dry through two full rainy seasons.

Maintenance: Clear drains and scuppers quarterly, walk the roof twice a year, and reseal penetrations every 24 to 36 months. We offer an annual maintenance plan that covers all of it.

Before

A homeowner had a leaking flat roof over a detached garage. The original EPDM membrane was brittle and cracked, flashing at the parapet wall had failed, and water was staining the interior wall and rotting the bottom plate.

After

We replaced the membrane with a new fully adhered EPDM system, installed new termination bars and counterflashing, and replaced the rotted bottom plate. The total came in under $4,000, and the garage has stayed dry through two springs.

Maintenance: Inspect the parapet flashing each fall, keep the roof clear of leaves and debris, and reseal the wall tie-in every three years. The EPDM carries a 20-year material warranty.

Before

A restaurant owner called after a ceiling stain spread over the dining room during a two-day rain event. The leak was active, and the roof had visible ponding water and failed flashing at a rooftop HVAC curb.

After

We tarped the roof the same day, traced the leak with a moisture meter and infrared camera, and repaired the flashing and drainage. The ceiling dried out, and the repair cost $1,850 instead of the $14,000 full replacement the owner feared.

Maintenance: Schedule a roof inspection every spring before rainy season, keep HVAC curbs sealed, and clear drains monthly during heavy rain months. We can bundle this into an annual maintenance contract.

Flat Roof Problems We Solve Across Texas

Most flat roof calls come down to water finding a way in. Here are the problems we see most often and how we fix them before they cost you a ceiling.

Problem

Ponding water sitting on the membrane after every rain

Standing water breaks down seams, grows algae, and adds structural load. Left alone, it turns a $2,000 repair into a full deck replacement within a few years.

Our Fix

We core-test the deck, add tapered insulation to build proper slope, and reset drains and scuppers so water exits within 48 hours of a storm. Most ponding fixes are handled during a scheduled replacement, not as an emergency.

Problem

Flashing failure at parapet walls and penetrations

Water weeps behind the wall and shows up as a ceiling stain far from the actual leak. By the time you see it, the insulation is already wet and the damage is spreading.

Our Fix

We remove the old flashing, install new termination bars and counterflashing, and reseal every penetration with compatible sealant. We hose-test the area before we leave so you know it is fixed.

Problem

Hail punctures and seam separation after a storm

Small punctures let in water that soaks insulation and rusts deck fasteners. If the claim is not documented properly, your insurance payout may not cover the full repair.

Our Fix

Our HAAG-certified inspectors photograph every impact, core-test the deck, and write a report your adjuster can use. We tarp the roof the same day and schedule permanent repairs within 48 hours.

Problem

UV breakdown and premature membrane aging

Texas sun bakes a membrane until it chalks, cracks, and loses flexibility. A roof that should last 20 years starts failing at 10 or 12.

Our Fix

We spec reflective white TPO or a UV-resistant coating system on sun-exposed decks. A recoating every 10 to 12 years adds another decade of life for a fraction of replacement cost.

Why Texas Property Owners Choose Flat Roof Systems

Why Texas Property Owners Choose Flat Roof Systems

A flat roof gives you usable deck space, easier maintenance access, and a membrane that handles standing water better than shingles ever will. Here is what that means in practice.

  • Walkable, Serviceable Deck

    You can walk a flat roof without damaging it, which makes HVAC service, solar mounting, and annual inspections simple. We install walk pads around rooftop units so techs stop punching holes in the membrane. That single detail prevents most of the Texas flat roofing for leaks calls we run.

  • Heat-Reflective Membranes

    White TPO reflects sunlight and drops surface temps by 30 to 50 degrees compared with black asphalt. On a 100-degree July afternoon in Odessa, that difference shows up on your cooling bill. We spec reflective membranes on most Texas flat roofing cost estimates because the energy savings pay back the upgrade.

  • Fewer Wind-Lift Failures

    A properly adhered membrane resists uplift better than individual shingles that peel off one at a time. We use GAF and Carlisle SynTec systems rated for 55 to 75 mph wind zones, then add edge metal and termination bars so the perimeter stays locked down through a spring squall line.

  • Longer Service Life

    A 60-mil TPO membrane typically lasts 20 to 25 years in Texas when seams are heat-welded and drains stay clear. That beats the 12 to 15 years many shingle roofs see under the same sun load. We hand you a maintenance schedule so you actually get those years.

Flat Roofing Cost in Texas

Typical 2026 pricing for flat roofing in Texas runs $6 to $12 per square foot for residential replacement and $8 to $16 per square foot for commercial TPO systems. Repairs are far cheaper, usually $450 to $2,500. The biggest cost drivers are roof size, membrane type, insulation thickness, and how much wet material has to come out. We give you a written, line-item quote after the free inspection, and we do not add cost without your approval.

Typical Investment Range

$450 - $18,000+ depending on repair vs. full replacement and roof size

A flat roof replacement costs more upfront than patching, but it ends the cycle of repeat repairs. Most of our customers break even within three to five years compared with annual leak fixes, and they get a dry building and a transferable warranty.

What changes the price

01

Roof Size and Access

Larger roofs cost more in total but less per square foot. Steep access, tight lots, and rooftop equipment add labor. A 1,500-square-foot residential roof runs $9,000 to $18,000 installed.

02

Membrane Type

TPO is the most common and cost-effective option. EPDM runs slightly higher. Modified bitumen is cheaper on small residential jobs. Membrane thickness, from 45-mil to 80-mil, also moves the price.

03

Insulation and Slope

Adding tapered insulation to fix ponding water adds $1.50 to $3.50 per square foot. It is the single best investment you can make because it extends membrane life by 10 or more years.

04

Wet Insulation Removal

If the deck is wet, we have to remove and replace the saturated insulation. That can add $2 to $4 per square foot. A moisture meter and infrared scan tell us the scope before we quote.

05

Flashing and Penetrations

Every HVAC curb, vent, skylight, and parapet wall needs flashing. Buildings with many penetrations cost more to detail. We price each one in the written scope so nothing is hidden.

06

Warranty Term

Longer manufacturer warranties require specific membrane thicknesses and installation methods. A 20-year NDL warranty costs more than a standard 10-year material warranty, but it protects you longer.

Frequently Asked Questions About Flat Roofing in Texas

Real answers to the questions we hear most often from local homeowners and property managers.

How much does flat roofing cost in Texas?
Most residential flat roof replacements in Texas run $6 to $12 per square foot in 2026, so a 1,500-square-foot roof lands between $9,000 and $18,000. Commercial TPO systems run $8 to $16 per square foot depending on insulation thickness and number of penetrations. Repairs are far cheaper, usually $450 to $2,500. We give you a written, line-item quote after the inspection.
What is the best flat roofing material in Texas?
For most Texas buildings, 60-mil white TPO is the best balance of heat reflection, seam strength, and price. EPDM lasts longer in some applications but absorbs heat. Modified bitumen works well on small residential porches and additions. We spec the membrane to your deck, slope, and budget, not to whatever is cheapest that week.
How long does flat roofing last in Texas?
A properly installed TPO membrane lasts 20 to 25 years in Texas. EPDM can reach 25 to 30 years. Modified bitumen typically gives 15 to 20 years. The single biggest factor is drainage. If ponding water on flat roofs is not corrected, any membrane fails early, usually within 8 to 10 years.
How to prevent leaks on flat roofs in Texas?
Keep drains and scuppers clear, walk the roof twice a year, and reseal penetrations and edge metal every 24 to 36 months. After any hail event, have us inspect for punctures and flashing failure before the next rain. We offer a maintenance program that covers all of this for a flat annual fee, and it adds years to the membrane.
