What Is TPO Roofing?

TPO roofing is a Thermoplastic Polyolefin single-membrane system for flat and low-slope commercial buildings. The membrane combines polypropylene and ethylene-propylene rubber, as detailed by the Single Ply Roofing Industry. This creates a durable, energy-efficient material that reflects UV rays.

TPO comes in three thicknesses: 45 mil, 60 mil, and 80 mil. TPO roofing can range in price from $5 to $12 per square foot, depending on thickness and scope of work. The white reflective surface cuts cooling costs by not allowing the building to absorb as much heat. Your roof lasts 20 to 30 years with proper maintenance, according to NRCA roofing guidelines.

Installation involves mechanically attaching or fully adhering the membrane to your roof deck. We then heat-weld the seams for watertight protection. This process creates strong, permanent bonds that withstand Texas weather conditions.

TPO roofing protects warehouses, offices, retail centers, and multi-family buildings across DFW. The system meets building codes and performs in extreme heat and storms. Ready to get started? Contact us for a free TPO roofing estimate.

TPO Roofing Systems Explained

TPO membranes blend polypropylene and ethylene-propylene rubber through heat and pressure. Manufacturers add UV stabilizers, flame retardants, and colorants during production. The result is a flexible, weather-resistant membrane that handles Texas temperature swings.

You choose between reinforced and non-reinforced TPO membranes. Reinforced membranes include a polyester or fiberglass scrim layer. This layer adds strength and puncture resistance. We recommend reinforced TPO for all commercial buildings in Dallas-Fort Worth. Non-reinforced membranes work for small residential applications but lack the durability your commercial property needs.

TPO Thickness Options

(based on manufacturer warranty specifications)

Most commercial buildings in DFW perform well with 60 mil TPO. You need 80 mil if your roof supports HVAC units or sees regular maintenance traffic. We inspect roof activity patterns before recommending thickness.

White TPO reflects the most heat and is standard across Dallas-Fort Worth. You can also choose tan or gray TPO to match your building design, as shown in GAF's TPO color chart. Custom colors are available but may add time to your installation timeline.

TPO Roofing for Commercial Buildings

Flat and low-slope commercial roofs need different protection than residential steep-slope systems. Water pools on flat surfaces. Heat builds up faster. TPO roofing solves both problems with its waterproof membrane and reflective surface.

TPO meets International Building Code requirements for commercial roofing in Dallas-Fort Worth. The system also qualifies for ENERGY STAR ratings when installed with proper insulation. Your building stays compliant with local codes and insurance requirements.

How TPO Performs on Different Building Types

Installation Methods

Mechanical attachment involves fastening the TPO membrane directly to your roof deck with plates and screws. We then heat-weld the seams. This method works well for most commercial buildings and allows for roof movement.

Fully adhered installation bonds the entire membrane to the substrate with adhesive. You get maximum wind uplift resistance. We recommend this method for high-wind areas and buildings over three stories.

Ballasted systems use river rock or pavers to hold the membrane in place. This option costs less upfront but requires a structural engineer to confirm your roof can handle the weight.

Low-slope TPO systems may need tapered drainage depending on whether the deck is framed to pitch. We assess your building's structure and drainage needs during the planning phase.

Premium TPO Warranty Options

Premium TPO systems from manufacturers like GAF, Versico, and Firestone come with warranties ranging from 10 to 20 years. Your warranty length depends on membrane thickness and installation method. We help you choose the warranty that matches your building's needs and budget.

Benefits of TPO Roofing

TPO roofing delivers measurable savings on your commercial building's operating costs. The white reflective surface earns ENERGY STAR ratings across Dallas-Fort Worth. The white reflective surface cuts cooling costs by not allowing the building to absorb as much heat.

Your air conditioning units run less during summer months. Lower energy consumption means smaller utility bills and reduced strain on HVAC equipment. Many DFW building owners see return on investment within several years through energy savings alone.

TPO costs less than PVC roofing while offering similar performance. PVC typically runs higher per square foot. EPDM costs slightly less but absorbs more heat. TPO gives you the best balance of upfront cost and long-term energy savings.

Restaurant owners choose TPO for its chemical and grease resistance. Kitchen exhaust doesn't degrade the membrane. Grease buildup cleans off easily during routine maintenance. Your roof protects your business even with heavy kitchen ventilation.

TPO stays flexible in cold weather. The membrane doesn't crack during Texas winter freezes. This flexibility also helps during installation. We can install TPO year-round in the DFW climate without weather delays.

Environmental Benefits

Premium TPO systems from GAF, Versico, and Firestone meet the highest industry standards for reflectivity and durability. Your building gains protection and efficiency from a proven system.

TPO Roofing Cost Breakdown

TPO roofing can range in price from $5 to $12 per square foot, depending on thickness and scope of work. Your final price depends on membrane thickness, roof size, and installation complexity.

TPO Pricing by Thickness

• 45 mil TPO: Lower cost option for basic protection
• 60 mil TPO: Mid-range pricing for standard commercial use
• 80 mil TPO: Higher investment for heavy-duty applications

These prices include tear-off, insulation, membrane, and labor. Larger roofs cost less per square foot because fixed costs spread across more area. A 5,000 square foot warehouse roof runs more efficiently than a 1,500 square foot retail space.

Factors That Affect Your TPO Roofing Cost

Roof complexity adds to installation time and materials. Multiple penetrations for HVAC units require more flashing work. Parapets and unusual shapes increase labor costs. Simple rectangular roofs with few penetrations cost less.

Access to your roof affects pricing. Ground-level commercial buildings allow easy material delivery. Multi-story buildings need crane rentals or hoisting equipment. We factor accessibility into your quote.

Existing roof condition matters. Clean decks ready for new membrane cost less than roofs needing structural repairs. We inspect your deck during estimates to identify any issues.

TPO vs. EPDM vs. PVC Cost Comparison

TPO delivers the best value for standard commercial applications. You get energy savings close to PVC without the higher price. EPDM costs less initially but your cooling costs stay higher.

TPO Roofing Durability and Maintenance

TPO roofing lasts 20 to 30 years when properly installed and maintained, according to NRCA roofing guidelines. Your actual lifespan depends on membrane thickness, installation quality, and maintenance schedule. Thicker membranes and regular inspections extend your roof's service life.

Common TPO Roofing Issues and Prevention

Seam failures happen when heat welding is done incorrectly during installation. We test every seam during installation to confirm proper bonding. This prevents leaks before they start. Choose experienced TPO installers to avoid this problem.

Punctures from foot traffic or falling debris can damage your membrane. Schedule maintenance during cooler hours when the membrane is less vulnerable. Use walkway pads in high-traffic areas around HVAC units.

Ponding water shortens membrane life if drainage is poor. Water that sits longer than 48 hours after rain breaks down the membrane faster. We check drainage during installation and adjust slopes when needed.

Shrinkage occurs as TPO membranes age. The material contracts slightly over time. Proper attachment methods accommodate this movement. Mechanically attached systems handle shrinkage better than fully adhered installations.

Inspection Schedule for Your TPO Roof

Inspect your roof twice per year in spring and fall. Look for loose seams, punctures, and debris buildup. Clear drains and check flashing around penetrations. Document conditions with photos.

Schedule professional inspections every few years. We check membrane attachment, seam integrity, and early wear patterns. Catching small issues early prevents expensive repairs later.

Inspect after severe weather events. Hail and high winds can damage even new TPO roofing. Texas storms require prompt inspection to file insurance claims within deadlines. Learn more about our professional roof inspection services.

Repair vs. Replacement Indicators

Repair your TPO roof when damage is localized. Single punctures, small tears, and isolated seam failures are repairable. We patch damaged areas and re-weld seams. Repairs are cost-effective for limited damage.

Replace your TPO roof when you see widespread issues. Multiple leaks across different areas signal membrane failure. Extensive shrinkage pulling away from edges means replacement time. Visible deterioration across significant portions of your roof surface requires a new system.

Our Experience with TPO Installation

We've installed all major TPO brands across Dallas-Fort Worth commercial properties. Each manufacturer offers unique advantages for different applications.

Most recently, we installed GAF EverGuard on a 25,000 square foot office building in Waxahachie, TX using a fully adhered system. The installation was completed in October 2025. The fleece backing made the installation process smoother despite the Texas heat, and the fully adhered method provides maximum wind uplift resistance for this commercial property.

We handle all types of commercial roofing. Every roof is different, and being able to work with a variety of products and scenarios is one of Under One Roof's strong suits.

Choosing the Right Brand for North Texas Climate

Dallas-Fort Worth weather demands TPO that handles extreme heat and sudden storms. Summer temperatures reach 105°F on roof surfaces exceeding 160°F. Your TPO membrane must maintain flexibility and reflectivity in these conditions.

All major TPO brands from GAF, Versico, and Firestone show excellent long-term performance in sustained Texas heat. The reinforcement layers resist thermal stress and maintain integrity through temperature extremes.

Hail resistance varies by membrane thickness more than brand. Choose 60 mil or thicker TPO in North Texas. Hail storms hit DFW regularly. Thicker membranes survive impact better and qualify for better insurance rates.

Wind uplift ratings matter for taller buildings. Premium TPO systems achieve Class 90 wind ratings with proper attachment. Your building stays protected during severe thunderstorms common in spring and fall.

We help you select the TPO brand and thickness that matches your building type, budget, and warranty expectations. Our partnerships with leading manufacturers ensure you get access to the best warranties and products available. Learn more about our commercial roofing options for your Dallas-Fort Worth property.
