TPO Roofing Installation for Commercial Buildings
In the world of commercial roofing, TPO roofing has become a superstar due to its excellent balance of cost, performance, and energy efficiency. TPO stands for Thermoplastic Polyolefin, a single-ply roofing membrane that is widely used on commercial flat roofs. RISE Roofing has extensive experience installing and maintaining TPO roofing systems. We bring a formal, knowledgeable approach to educating our clients about TPO: what it is, its benefits, and why it might be the right choice for your commercial building. In this section, we’ll cover the key aspects of TPO roofing and how RISE Roofing ensures a top-quality TPO installation that will protect your property for years to come.
Overall, TPO roofing offers a modern solution for commercial roofs that is relatively quick to install, light-weight (not adding much structural burden), and offers great performance in various climates. It’s important, however, that TPO is installed by trained professionals like our team at RISE Roofing, because proper welding technique and detailing are key to its long-term success.
What is TPO Roofing?
TPO (Thermoplastic Polyolefin) is a type of single-ply membrane – meaning it’s a flexible sheet of synthetic material that is rolled out and adhered or fastened to the roof in one layer. Here’s a breakdown of TPO Roofing and how it works.
Material Composition
TPO is made from a blend of polypropylene and ethylene-propylene rubber. This blend results in a material that is durable like rubber but can be heat-welded like plastic. The membrane typically comes in rolls (commonly 45, 60, or 80 mil thicknesses, where a mil is one-thousandth of an inch). The most popular color for TPO is white, although it also comes in grey and tan. The white color is highly reflective, which is a big part of its appeal.
Installation Method
TPO can be installed in a few ways. The most common is mechanically attached – where the membrane is rolled out and secured to the roof deck with screws and plates along the seams, then the seams are heat-welded together with a hot air gun, melting the material at the overlap to form a seam that, once cooled, is as integrated as the membrane itself. It can also be fully adhered using special bonding adhesive – this method is often chosen for concrete decks or when you want to avoid penetrating the deck with fasteners. Another method is ballasted, where the TPO is loose-laid and then covered with heavy gravel or pavers; this is less common these days due to the weight involved.
Seam Welding
One of the key advantages of TPO Roofing (and PVC) is the heat-welded seams. Unlike EPDM which uses adhesives or tapes, TPO’s seams are fused with heat, creating a very strong bond that is effectively one continuous sheet. A proper weld actually fuses the two sheets into one, making the seam as strong as the field membrane. This ensures water cannot penetrate at the seams, which are often the weakest point in other systems.

Environmentally Friendly
TPO Roofing is often touted as a “green” roofing choice. It is a cool roofing material due to its high reflectivity, which we’ll discuss more as a benefit. Also, TPO Roofing does not contain chlorine (unlike PVC), and it can be recycled at the end of its life in some cases. The hot-air welding means no volatile organic compounds (VOCs) are released during installation (as can happen with some solvent-based adhesives or asphaltic systems).
Benefits of TPO Roofing
TPO Roofing has surged in popularity for many good reasons. Let’s explore the benefits of choosing a TPO roofing system for your commercial building.
One of the biggest draws of TPO Roofing is its energy-saving potential. The white (or light-colored) TPO membrane has high solar reflectance, meaning it reflects a large portion of the sun’s rays rather than absorbing them. This helps keep the building cooler, reducing the load on air conditioning systems during hot, sunny days. In fact, TPO roofing can significantly lower rooftop temperatures compared to a dark-colored roof. This cool roof effect not only saves on energy bills but can also extend the life of the roof and rooftop HVAC equipment (as they operate in a cooler environment). TPO roofing often meets or exceeds ENERGY STAR® qualifications and other cool roof standards set by municipalities or environmental programs.
TPO Roofing generally offers a lower material cost compared to some other single-ply membranes like PVC, while providing similar benefits. It often falls in a sweet spot of being more affordable than PVC and more feature-rich (reflective, heat-weldable seams) than EPDM. For building owners looking to balance upfront cost with performance, TPO Roofing is frequently the best value choice.
TPO Roofing membranes are formulated to resist cracking and crazing (the micro-cracks that UV can cause in some materials) over time. They handle thermal expansion and contraction well, which is important on large roofs that see wide temperature swings between day and night. TPO Roofing is also algae-resistant and doesn’t propagate flame (many TPO Roofing membranes have a Class A fire rating when properly installed in a system). They perform reliably in both hot climates (where white membranes excel) and cold climates (flexibility in cold weather is good, although installation in very cold temperatures is generally avoided for any roofing).
Once a TPO roof is properly installed, it requires minimal maintenance. The material is resistant to dirt and debris accumulation to some extent (though regular cleaning is advisable to maintain reflectivity). The welded seams don’t peel or come apart as glued seams might, so there’s less likelihood of seam failures over time. Of course, like any roof, periodic inspections are recommended, but TPO roofing doesn’t have many built-in maintenance needs aside from perhaps re-caulking sealant at some metal flashings every so often.
TPO, especially in thicker gauges (80 mil, for example), offers good puncture and tear resistance. If your roof sees light foot traffic for maintenance or has some incidental exposure to falling small debris, TPO can usually handle it. In cases where extra durability is needed, we can also install walkway pads (often made of TPO material) in high-traffic areas, so the roof surface stays protected.
TPO membranes come in wide rolls (often 10 feet wide or more), which means fewer seams on a large roof and a cleaner look. The bright white finish gives a crisp, clean appearance that many owners prefer for a neat-looking rooftop (especially if the roof is visible from higher buildings or the ground). If white isn’t desired, the grey or tan options can better blend with certain building designs while still providing some reflectivity.
In conclusion, TPO Roofing provides a combination of economic and performance advantages that make it a top contender for many commercial roofing projects. It’s particularly attractive for large flat roofs where cost savings on energy and installation really add up.
TPO vs. Other Commercial Roofing Options
It’s often helpful for clients to understand how TPO Roofing stacks up against other common roofing systems.
PVC (another single-ply membrane) is actually quite similar to TPO Roofing in many respects. Both materials are installed in sheets with heat-welded seams and often white and reflective. PVC has a longer track record (used since the 1960s) and is known for superior chemical resistance (it handles grease, oil, and chemical exposure exceptionally well). It can also remain flexible in extremely cold temperatures. However, PVC typically comes at a higher cost than TPO. PVC may also be slightly more rigid to work with in installation (depending on formulation). Choose PVC if your roof will see chemicals or you want that long proven history and don’t mind the extra cost; choose TPO if you want similar performance in most categories at a more affordable price point.

EPDM is a rubber membrane, usually black (though available in white with a coating). EPDM is very flexible and has great UV resistance. It’s been a staple of commercial roofing for decades. EPDM seams are glued or taped, not welded. EPDM advantages: It’s very forgiving during installation (stretchy, handles building movement well), and can be ideal in cold climates (black surface helps melt snow, and it remains flexible). It also tends to be quiet (rain noise) due to its softer rubber nature. EPDM disadvantages: The black version absorbs heat (bad for cooling costs, unless you get a white-on-black variant), and seams are typically the weak point (modern tapes are good, but still not as monolithic as welded seams). Also, EPDM can be more easily punctured by sharp objects (it’s tough but a bit softer than TPO). TPO vs EPDM: TPO wins on reflectivity and seam strength; EPDM might edge out in extreme cold flexibility and maybe slightly lower cost in some cases. Many building owners are now choosing TPO Roofing over EPDM for the energy benefits alone.
These are multi-ply, bitumen-based roofs. Advantages of Mod-Bit/BUR: They have multiple layers, which means redundancy (if one layer has a defect, the layers below still protect). They are time-tested and can handle roof traffic and abuse well (especially with a gravel top or cap sheet). They don’t have the same seam concerns because overlapping plies inherently seal together with the asphalt. Disadvantages: They are heavier, take longer to install (more labor-intensive), and typically not reflective unless a reflective cap sheet or coating is applied. They also can have odors/fumes during installation (if hot mopped or torched). TPO installations are usually quicker and cleaner. TPO might require less maintenance in terms of not needing periodic coatings, etc. Choose modified bitumen/BUR for small roofs with lots of penetration or if you want the extra toughness and don’t mind the extra weight and possibly higher cost; choose TPO for most large, open flat roofs for ease and energy efficiency.

This is almost an apples vs oranges, since metal is used on sloped roofs mostly. Metal lasts a very long time and is extremely durable, but it’s much costlier per square foot than TPO and not feasible on flat roofs without adding slope structure. TPO Roofing is the go-to for flat; metal for pitched. Some buildings use a combination (metal on pitched sections, TPO on flat deck sections).

Sometimes instead of re-roofing, owners consider a roof coating over an existing roof. A white silicone or acrylic coating can restore some reflectivity and seal minor leaks, buying time on an aging roof. Coatings are generally cheaper short-term but they are more of a band-aid and have to be re-applied every so often. If you want a true new roof with warranty, TPO is a better long-term solution. Coatings might be used as a stopgap or if the budget is very tight, but they won’t last as long as a new TPO membrane.
This comparison is something our team at RISE Roofing is happy to elaborate on in person, with samples and more detailed cost-benefit breakdowns. It’s clear that TPO Roofing stacks up very well against the alternatives for many applications, which is why it’s a top choice in the industry today.
TPO Roofing Cost & Warranty
TPO roofs are relatively low-maintenance, but like any roof, some care will ensure you get the maximum life out of your investment. Here’s how RISE Roofing supports you in maintaining your TPO roof.
We recommend at least annual inspections for TPO roofs (or semi-annual, especially in harsher climates or after major storms). During these inspections, we check the membrane’s condition, look for any punctures or damage, inspect seams, and ensure flashings are secure. We’ll also make sure no debris has accumulated and that drains are clear. This proactive check can catch issues like a loose edge metal or a tiny hole from a dropped tool before it ever leaks.
To keep your TPO roof reflective and pretty, it may need cleaning every couple of years. TPO can collect dirt and some algae over time which dulls the white surface. We offer roof cleaning services where we use non-destructive methods (soft washing, non-abrasive scrubbers) to lift off the grime without harming the membrane. A clean TPO roof not only looks better but performs better in terms of reflectivity.
If damage is spotted – say an HVAC contractor dropped a screwdriver and punctured the membrane – it’s important to repair it soon. TPO is relatively easy to patch by a professional: we clean the area and heat-weld a patch of new TPO over the hole. Because it’s welded, the patch becomes part of the roof. Timely repair prevents water from getting under the membrane and causing bigger problems. We advise clients to let anyone who works on the roof know to report any accidents (like a dropped tool or a spill) so that we can come fix it. Often these repairs are quick and not costly, especially if under a maintenance contract.
While TPO Roofing seams are strong, after many years (toward the late life of the roof) slight separations or weaknesses can develop if, for instance, there was slight under-heating in a spot during original weld. During maintenance checks, we’ll probe seams and can re-weld any suspect areas. Likewise, we’ll check the sealant on any termination bars or around drains; re-caulk or reseal as necessary. A little touch-up as the roof ages can extend its life a few more years.
If your TPO roof has a manufacturer’s warranty, we help you stay compliant with it by performing the required maintenance and keeping records. Typically, manufacturers want proof of inspections and maintenance, especially after 10 or 15 years. With RISE Roofing maintaining your TPO roof, you’ll have all the documentation needed to keep warranty coverage intact.
As your TPO roof nears the end of its expected lifespan (say 20 years), we can help plan for its replacement or refurbishment. Sometimes a roof can be recovered (another layer of TPO installed over the old after proper prep) if the existing one is still basically dry underneath. Or it might be time to tear-off and re-roof with new material. Because we’ve been maintaining your roof, we’ll know its condition intimately and can give you sound advice on the most cost-effective path forward.
The good news is, a well-installed and maintained TPO roof shouldn’t give you much trouble over its life. By partnering with RISE Roofing for periodic check-ups, you can essentially set it and forget it, aside from the scheduled visits where we do our thing. We aim to make roof ownership worry-free for you.
Our TPO Roof Installation Process
RISE Roofing is a leading TPO roofing installer in Texas, Our expertise ensures that your TPO roof is installed correctly for maximum performance and lifespan.
We maintain certifications with major TPO roofing manufacturers (such as GAF, Carlisle, Firestone (Elevate), Johns Manville, etc.). This means our crew members have been trained in those manufacturers’ installation methods. It also allows us to offer enhanced warranties, like 20- or 25-year No-Dollar-Limit (NDL) warranties backed by the manufacturer, because they trust that our installation meets their quality standards.
A good TPO installation requires proper tools. We utilize advanced hot-air welding machines, from handheld welders for detail work to automatic robotic welders for long seams. These machines ensure consistent, strong seams. We also use calibrated sensors to monitor heat settings, so the welds are just right (too cold and it won’t bond; too hot and it could burn the membrane). Our investment in equipment translates to reliable, tight seams across your roof.
Where many TPO Roofing installations fail is not in the open field, but at the details – around pipes, drains, corners, and edges. Our technicians are masters of the craft when it comes to TPO detailing. We make custom-fit boots and patches that cover every odd shape or penetration on your roof, all welded seamlessly. The result is a uniform, watertight system. We also pay attention to things like proper termination bars and edge seals (applying edge sealant where required by manufacturers, such as on cut edges of reinforced TPO) – these little steps ensure the longevity of the installation.
Each TPO roofing manufacturer has specifications for things like how far apart fasteners should be, how wide seams should overlap, how to prep surfaces for adhesion, etc. We strictly follow these specs. For example, if 12 inches on center for perimeter fastening is required (per high wind uplift areas), we do that; if double-welding at certain spots is recommended, we do it. By the book installation means your roof will perform as tested and will pass any warranty inspection with flying colors.
Welding TPO involves very hot equipment – our crew is well-trained to handle this safely, preventing any fire risk or accidents. We also keep the work area clean, removing any scraps of membrane or backing papers (from adhesive rolls, etc.) so that nothing gets trapped under the membrane or clogs a drain. A tidy work site also means a safer site – no tripping hazards or debris left behind. When we finish a TPO roofing job, the roof looks clean, smooth, and professional.
After installation, we perform tests on our welds. One common test is a “probe test,” where we run a specialized tool along the seam to check for any voids (areas not fully welded). If any weak spots are found, we repair them immediately (typically by re-welding or patching). For critical projects, we can also do cut-out samples (where a small piece of a welded seam is cut and peeled to inspect the bond – then patched over). These quality control measures ensure that when we declare the roof complete, it is truly secure.
Choosing RISE Roofing means choosing a contractor who knows TPO inside and out. We take pride in turning rolls of membrane into a tough, seamless shield for your building. Many of the problems people hear about with TPO Roofing (like seam failures or membrane issues) stem from poor installation practices – with us, you can be confident that won’t be the case. Our goal is a TPO roof that performs at or above expectations for its entire service life.

TPO Roofing FAQ
What is TPO roofing and why is it used on commercial buildings?
TPO (Thermoplastic Polyolefin) roofing is a single-ply membrane commonly used on commercial buildings with flat or low-slope roofs. It’s made of a blend of rubber and plastic that offers excellent flexibility and UV resistance. TPO is heat-welded at the seams, creating a watertight seal that outperforms traditional adhesives. It’s also energy-efficient due to its bright white reflective surface, which helps reduce heat absorption—making it ideal for buildings in hot climates like Houston and Corpus Christi. Property owners choose TPO for its affordability, performance, and low maintenance.
How long does a TPO roof last in Texas weather conditions?
A professionally installed TPO roof can last between 20 to 30 years, depending on membrane thickness, installation quality, and exposure. In Houston and Corpus Christi, where roofs endure high UV exposure, hurricanes, and heat, TPO performs well due to its resistance to ozone, algae, and thermal shock. RISE Roofing installs reinforced TPO systems that resist punctures and ponding water and come with optional 20- to 30-year manufacturer warranties. We recommend annual inspections to extend lifespan and keep warranty coverage intact.
Is TPO roofing energy efficient?
Yes, TPO is one of the most energy-efficient commercial roofing systems available. Its white reflective surface meets ENERGY STAR® and Cool Roof Rating Council (CRRC) standards. By reflecting UV rays, TPO helps reduce HVAC workload and lower cooling costs—especially important in heat-intensive markets like Houston. Some utility companies even offer rebates for cool roof installations. TPO's energy-saving benefits make it a popular choice for warehouses, retail stores, office complexes, and more in Texas.
What thickness of TPO membrane should I choose?
TPO membranes are typically available in 45 mil, 60 mil, and 80+ mil thicknesses. For Texas buildings, we usually recommend 60 mil or thicker to improve puncture resistance and lifespan. Thicker membranes are more durable and qualify for extended warranties. They’re especially beneficial in high-traffic areas or buildings with rooftop equipment. During your consultation, RISE Roofing will assess your roof and recommend the appropriate thickness based on budget, exposure, and long-term performance goals.
Can TPO be installed over an existing roof?
In many cases, yes. TPO can be mechanically attached or fully adhered over an existing roof if conditions allow. However, local building codes limit roof overlays to one layer. Before recommending an overlay, RISE Roofing performs a core cut to inspect insulation, decking, and moisture levels. If the existing roof is saturated or structurally compromised, a full tear-off may be required. Overlaying with TPO can reduce installation time and cost if conditions are right.
Is TPO better than PVC for flat roofing?
TPO and PVC are both high-performance single-ply roofing systems, but each has its strengths. TPO is generally more affordable and offers excellent energy efficiency and weldable seams. PVC provides superior chemical resistance and is better for restaurants or facilities with grease exhaust. For most commercial applications in Houston and Corpus Christi, TPO is a strong choice due to its balance of cost, durability, and heat reflectivity. RISE Roofing installs both and will help you choose based on your building’s needs.
How does TPO perform during storms or hurricanes?
TPO roofing performs exceptionally well when installed correctly. Its welded seams resist wind uplift and water intrusion. RISE Roofing follows TDI (Texas Department of Insurance) guidelines to install TPO in coastal areas like Corpus Christi, ensuring it passes windstorm certification. Reinforced TPO membranes can withstand high wind loads, and the material is resistant to hail, fire, and UV degradation. Proper attachment to the substrate and quality edge termination are key to its storm resistance.
What maintenance is required for a TPO roof?
TPO roofing requires minimal maintenance compared to multi-layer systems, but regular inspections are essential. We recommend a biannual inspection (spring and fall), plus checks after major storms. Maintenance includes removing debris, checking seams, re-sealing penetrations, and inspecting for punctures or membrane wear. Preventive care helps preserve warranty coverage and extend roof life. RISE Roofing offers affordable commercial maintenance plans tailored for TPO systems in Texas.
Is TPO safe and environmentally friendly?
Yes. TPO roofing is a safe and environmentally responsible choice. It’s free of chlorine and plasticizers and is fully recyclable at the end of its life. Its reflective surface reduces the urban heat island effect and cuts down on greenhouse gas emissions by lowering cooling demands. For businesses focused on sustainability or LEED certification, TPO aligns with many green building goals. RISE Roofing uses materials from reputable manufacturers that meet strict environmental standards.
Do you offer warranties for TPO roofing systems?
Absolutely. RISE Roofing installs TPO systems from top manufacturers like Elevate and Polyglass, offering 15-, 20-, and 30-year material and labor warranties. We also back our work with a lifetime workmanship warranty for added peace of mind. For buildings in Houston and Corpus Christi, we ensure your system meets or exceeds local wind uplift codes, which is often a requirement for full warranty eligibility. Warranties vary by membrane thickness, attachment method, and insulation—so we’ll walk you through the best options.
