9 Signs Your Commercial Roof Needs Repair Before It Starts Leaking
You’re walking the roof or prepping for a budget meeting, and something looks off, but you don’t yet know if it’s a next-quarter fix or a call-today problem. Here’s the reassurance: a commercial roof leak almost never happens without warning. The warning signs that commercial roof problems needs repair before it leaks include ponding water lasting 48+ hours, blistering membrane, cracked seams and flashing, granule loss, interior stains, rising energy bills, corroded metal, membrane shrinkage, and blocked drains.
For a facilities manager overseeing a QSR franchise, catching these early is everything, since every hour a location closes for an emergency leak can cost $300 to $500 or more in lost drive-through and dine-in revenue.
Scheduling commercial roof repair the moment you spot these signs is what keeps a $600 fix from becoming an $80,000 replacement.
Key Takeaways
- Ponding water, cracked flashing, and membrane shrinkage are high-urgency signs. Get a contractor out within days, not weeks.
- Interior stains and musty odors mean water has already gotten past the membrane. This isn’t a wait-and-see item.
- NRCA recommends inspecting commercial roofs twice a year, in spring and fall, plus after every significant storm.
- We run repairs after hours and on weekends so QSR locations don’t lose a single operating hour.
- Houston’s 90+ days above 90°F, frequent hail, and a hurricane season that runs May through November accelerate nearly every sign on this list.
Why Do Commercial Roofs Fail Differently Than Residential Roofs?
A pitched shingle roof sheds water by design, and gravity does most of the work. A commercial roof doesn’t get that luxury. Most flat-roofed restaurants, strip centers, and multi-unit properties across Houston and Spring rely on low-slope systems, where water has nowhere to go but toward a drain, and if that drain is compromised, the water just sits there.
Flat and Low-Slope Roof Systems Explained
On a low-slope roof, standing water and membrane seams are where problems begin. A one-eighth-inch-per-foot slope is common on commercial builds. That sounds fine on paper, until debris, structural settling, or age flattens it out. That’s when ponding starts, and ponding is patient. It will find the smallest seam separation or a pinhole at a fastener and turn it into an active roof issue in weeks, not years.
Common Membrane Types and What Causes Them to Leak
The membrane itself matters too. TPO (Thermoplastic Polyolefin), EPDM (Ethylene Propylene Diene Monomer), Modified Bitumen, and Built-Up Roofing (BUR) each age and fail on their own timeline, with different seam types, UV tolerances, and repair methods.
| Membrane Type | Common Failure Point | Typical Repair Method |
| TPO | Heat-welded seam separation | Re-weld or patch |
| EPDM | Shrinkage at edges/walls, adhesive failure | Seam sealant, mechanical fastening |
| Modified Bitumen | Granule loss, surface cracking | Torch-applied or cold patch |
| BUR | Ply separation, surface wear | Recoat or section replacement |
Nearly every leak traces back to one of four sources: flashing and penetration failures, seam separation, prolonged ponding, or an aging membrane that has lost its flexibility. Manufacturers including GAF and Firestone Building Products design flashing systems to exacting tolerances specifically because penetration points, not the flat field of the roof, are where most leaks start. Contractors verify system performance against the ASTM E1105 water infiltration standard, and an infrared moisture scan can confirm whether moisture has already worked into the insulation layer before any interior sign appears.
The 9 Warning Signs Your Commercial Roof Needs Repair, Ranked by Urgency
These nine signs are ordered from most urgent to least, so you can size up what you’re seeing on a walkthrough and decide, on the spot, whether it’s a same-week call or a note for the next scheduled inspection.
High-Urgency Signs: Call Within Days
- Ponding water lasting 48+ hours. Standing water that hasn’t drained two days after rainfall is the clearest sign of a drainage or slope failure. Under the ASTM E1105 water infiltration standard, prolonged ponding is treated as an active risk factor, not a cosmetic issue, because sustained weight and UV exposure break down membrane fibers from below. Left alone, it speeds up every other failure on this list.
- Cracked or open seams and flashing. Seams and flashing, especially around HVAC penetration flashing, rooftop units, and vent stacks, are where the vast majority of leaks originate. A visible gap or lifted seam means water already has a path inside. This is the single most common repair call we get from QSR clients across Houston, and it’s rarely a coincidence that it clusters near rooftop equipment.
- Membrane shrinkage pulling away from walls or edges. This is especially common on aging EPDM systems, where the membrane physically contracts over time and pulls away from parapet walls or roof edges. It opens a gap right where flashing depends on a tight seal, and it can signal early sagging in the deck below if left unaddressed.
Medium-Urgency Signs: Schedule Within the Month
- Blistering or bubbling membrane. Trapped moisture or gas beneath the surface pushes the membrane up into visible bubbles. Not always an active leak yet, but it’s a sign the membrane has lost adhesion in that spot. Foot traffic or hail impact can rupture it fast, and left untreated, blistering often leads to soft spots and eventual sagging across that section.
- Visible rust or deterioration at metal flashing and drains. Corroded metal at drains, scuppers, and edge flashing means the watertight seal at those transitions is compromised. Rust physically thins the metal until it can no longer hold a seal, and a $400 flashing repair becomes a bigger membrane repair if it’s ignored through another storm season.
- Rising energy bills or HVAC strain. Wet insulation loses its R-value fast, and when that happens, ventilation and HVAC systems work harder to hold temperature, especially in a Houston kitchen running exhaust fans all day. If utility costs are climbing without an obvious cause, check whether insulation under the membrane has taken on moisture.
- Granule loss or surface wear on BUR or Modified Bitumen roofs. Granule loss exposes the asphalt layer underneath to direct UV, and algae staining often shows up in the same worn patches. Slower-moving than the others, but surface wear is often the first visible sign that a mod-bit roof is aging out of its effective lifespan.
Low-Urgency Signs: Monitor at Next Inspection
- Debris buildup blocking drains or scuppers. Leaves, pollen, and construction debris collecting at drains and in gutters is common, and it’s the easiest sign to fix. But blocked drainage is also the fastest route back to sign #1. This one deserves a five-minute check every time staff are on the roof, not just at scheduled inspections.
- Interior stains or musty odor. For many facilities teams, water stains on a ceiling tile are the first indoor sign anything is wrong. By the time staff notice it, the membrane has usually been compromised for a while. Ceilings signal moisture intrusion well after the roof itself failed, and walls are often the next area affected once a stain appears, especially near exterior corners. An infrared moisture scan can confirm how far moisture has already traveled under the deck before it shows up as visible water damage indoors. Treat any interior spots or a musty smell as confirmation that this list needs immediate action, not routine monitoring.
If you’re seeing any of the high-urgency items above during a walkthrough, our commercial roof inspection checklist is a useful next step for documenting exactly what you found before you call.
How Often Should an Aging Roof Be Inspected?
The National Roofing Contractors Association recommends inspecting commercial roofs at minimum twice a year, once in spring and once in fall, to catch seasonal wear before it becomes a bigger repair [1]. That roof inspections cadence assumes normal conditions. Any property that just weathered hail, straight-line winds, or a tropical system needs an additional inspection immediately after, regardless of where it falls on the calendar.
Seasonal Roof Inspections Schedule
A spring inspection catches winter thermal cycling damage and clears debris before summer storm season. A fall inspection checks for UV wear from summer heat and confirms drains and gutters are clear before hurricane season winds down. Keeping a dated log with photos from each walkthrough gives you documentation ready-made for a franchise HQ budget request.
Post-Storm Inspection Triggers
Any hailstorm, sustained wind event, or heavy rainfall above what your drainage was designed for should trigger a walkthrough within 48 hours. For buildings where hidden moisture is suspected but not visible yet, an infrared moisture scan can locate trapped water under the membrane before it ever reaches a ceiling. A free drone inspection is an easy way to get an outside read without anyone stepping foot on the roof.
Can a Commercial Roof Be Repaired Without Closing the Business?
Yes. Most commercial roof services, including seam repair, flashing replacement, and section patching, can be completed during off-hours, overnight, or on weekends without closing the store or interrupting drive-through service.
Off-Hours and Weekend Crew Scheduling
We schedule crews around your operating hours, not the other way around. For a QSR location generating meaningful revenue during every open hour, having a contractor on the roof at 2 a.m. or on a Sunday morning is the difference between a routine repair and a lost shift’s worth of sales. One multi-unit QSR operator in the Houston area flagged a cracked seam near a rooftop HVAC unit during a routine walkthrough. Because the location couldn’t afford a daytime closure during lunch rush, our crew completed the seam repair overnight, and the store opened on schedule the next morning with zero lost revenue.
Phased Sectional Repair Strategy
On multi-unit properties or larger roofs, we divide the work into sections so HVAC access, kitchen exhaust, and drive-through equipment stay clear at all times. That phased approach means a repair covering several thousand square feet doesn’t require shutting down the whole building at once. If a leak has already progressed past the “schedule it for next month” stage, our emergency commercial roof repair in Spring, TX team can respond directly, keeping multi-location operators from having to coordinate more than one vendor.
How Does Houston’s Climate Speed Up Roof Problems and Damage?
Local weather doesn’t create these nine signs. It speeds up every one of them. Houston averages more than 90 days per year above 90°F, and that kind of sustained heat puts real thermal stress on membrane seams, a major contributor to the blistering described earlier [2].
Extreme Heat and Membrane Stress
Repeated expansion and contraction from daily heat cycles works seams loose over time, particularly at HVAC penetration flashing points where two different materials meet. UV exposure alone wears down TPO, PVC, and EPDM membranes faster than in milder climates, one reason membrane selection matters so much for a Houston building.
Hail, Thunderstorms, and Hurricane Season Risk
Houston averages 50 to 60 thunderstorm days a year, with a good share producing severe weather [3]. Hurricane season runs May through November and regularly brings wind speeds and wind-driven rain that test every flashing point and seam on a commercial roof [4]. That combination of frequent storms and sustained heat is exactly why 48-hour ponding checks and post-storm walkthroughs matter more here than in most parts of the country. For property owners weighing which membrane holds up best to Gulf Coast conditions, our guide comparing TPO and EPDM roofing systems breaks down the tradeoffs.
Schedule Your Commercial Roof Inspection Before It Leaks
You now have what you need: the exact language to describe what you’re seeing, and a clear sense of what’s urgent versus what can wait for the next scheduled visit. We hold Texas contractor license #03-0470 and carry GAF and Versico manufacturer certifications that allow us to issue 20-year NDL (No Dollar Limit) warranties, credentials that many franchise vendor-approval lists require before a contractor can even bid the work.

FAQ
How much does commercial roof repair cost?
Commercial roof repair costs typically range from a few hundred dollars for a small flashing or seam repair to several thousand dollars for larger membrane sections, depending on severity and roof size. Pricing depends heavily on how far damage has progressed before it’s addressed, exactly why catching a sign early matters. A free drone inspection gives you an accurate number rather than a guess.
What is the average lifespan of a commercial TPO or EPDM roof?
TPO and EPDM commercial roofing systems typically last 20 to 30 years when properly installed and maintained, while Modified Bitumen and BUR systems generally run 15 to 25 years [5]. Those figures assume regular maintenance and prompt repair of the signs covered above. An aging roof approaching the back half of that range should be inspected more often, not less.
How do you know if commercial roof damage is covered by insurance?
Storm-related roof damage, such as wind uplift or hail impact, is generally covered by commercial property insurance, while gradual wear from lack of maintenance typically is not. Insurers usually require documentation showing the damage resulted from a specific weather event rather than deferred maintenance. We provide inspection reports and insurance claims assistance to help document the difference clearly.
How much does it cost to replace a commercial roof versus repair it?
Full commercial roof replacement typically costs many times more than a targeted repair, which is why catching problems early has direct budget impact. Replacement costs scale with square footage and system type, while repair costs scale with how much damage has accumulated before it’s addressed. Scheduling an inspection is the most reliable way to keep repair costs from escalating into replacement costs.
What documentation should I bring to a franchise HQ budget meeting for roof repairs?
A franchise budget meeting typically requires dated photos, a written inspection report, and a contractor estimate to justify repair spend. Having this package ready before the meeting speeds up approval and shows ownership the request is based on documented conditions, not a guess. Our inspection reports are built specifically to support these conversations.
Do I need a licensed contractor for commercial roof repairs, or can maintenance staff handle it?
Commercial roof repairs generally require a licensed, manufacturer-certified contractor, particularly if the roof carries an NDL warranty that could be voided by unauthorized
The Best Roofing System for Restaurants: Duro-Last PVC
When it comes to choosing the best roofing system for restaurant owners, having a reliable, high-performing roof is critical to the long-term protection of your business. That’s why our team of roofing experts recommend the Duro-Last roofing system as the ideal roofing solution for restaurants.
In this blog post, we’ll explain what is Duro-Last PVC (Polyvinyl Chloride), the features that come along with this roof system, and why it’s the best choice for your restaurant.
Let’s get started!
What is Duro-Last PVC Roofing?
The Duro-Last PVC roofing system is a custom fabricated system consisting of a flexible, single-ply thermoplastic membrane optimal for flat or low slope roofs.
The Components of PVC
Roof Decking
A roof deck is the foundation for your roof. Deck material is the important structural element that helps support the insulation and waterproofing (membrane layers). Whether the project is a membrane tear-off, complete reroof or new construction the roof deck will be visually inspected before the application of the roof system.
Main Types of Commercial Roof Decking:
- Plywood or Oriented Strand Board (OSB)
- Steel – cold-rolled, corrugated
- Structural Concrete
- Lightweight Insulating Concrete
- Gypsum
Base Layer is Metal Panel Decking, Repaired Section of Decking
Complete Tear-Off
Insulation
This is the key to energy efficiency. Polyiso (polyisocyanurate) is the most commonly used type of insulation. It offers the highest R-value of any rigid insulation. R-value measures the insulation’s resistance to heat flow. It’s important to note that for commercial buildings, there are minimum insulation R-value requirements that vary from state.
Popular Types of Roof Insulation Available:
- Duro-Guard ISO
- Duro-Guard EPS Fan-Fold
- DensDeck

Roof Membrane
Duro-Last’s roof membranes come in varying thicknesses, measured in mils. The membranes are available in custom-fit, prefabricated sections. This membrane is custom-fabricated in sections up to 2,500 square feet, fitting each roof precisely to its unique specifications. Instead of in the field, up to 85 percent of the seams are completed under ideal, factory-controlled conditions – reducing waste, saving on labor and preventing leaks.
Membrane Thickness Options:
- 40 mil
- 50 mil
- 60 mil
Installation Process
Mechanically attached: The membrane is securely attached to the underlying roof deck using plates and fasteners along the seams, then the overlapping seams are heat welded using a heat gun or welding machine.
Fully adhered: The membrane is bonded directly to the insulation or roof deck using a bonding adhesive or low rise spray foam, typically the low rise spray foam sticks better. Then the overlapping seams are heat welded using a heat gun or welding machine.
Accessories
The Duro-Last system also includes prefabricated flashing, boots for pipes, and vents, ensuring a perfect fit for each roof. Custom-fabricated flashings are manufactured with Duro-Last membrane material and feature a weft-inserted scrim which provides puncture and tear resistance along with tensile strength at transitions – the most critical areas of any roof installation.
Why PVC Duro-Last Is Ideal for Restaurants
Durability
Duro-Last roofs are recognized as the best roofing system for their excellent durability and long-term performance. Here are a few features that contribute to the durability of a Duro-Last roofing system:
- Various membrane thicknesses based on specific needs, with thicker membranes offering better resistance to wear and tear.
- Resistance to chemicals, oils, and grease—critical for restaurant kitchen exhausts that can cause buildup on the roof.
- The ability to withstand high winds and extreme weather conditions.
- Reduced on-site installation errors and minimized seam completion thanks to each roof’s prefabrication at a Duro-Last manufacturing plant.
- Resistance to punctures and tears from foot traffic, debris, or maintenance equipment.
- Heat-welded seams provide a watertight bond that protects against leaks and weather damage.
This positions Duro-Last as the best roofing system for commercial and restaurant environments.
Longevity
A typical Duro-Last roof has an impressive lifespan of about 20-30 years. This longevity is primarily determined by two key factors: the thickness (mil) of the membrane and the quality of the installation.
Thicker membranes offer increased durability, providing better protection against the wear and tear common in commercial settings, particularly restaurants. Proper installation is also critical, as Duro-Last roofs are prefabricated in a controlled environment to ensure precision and reduce on-site errors, further enhancing their lifespan. With the combination of high-quality materials and expert installation, Duro-Last is consistently the top choice available, offering restaurant owners a reliable, long-lasting solution that can withstand the demands of their environment, from heavy foot traffic to harsh weather conditions.
Energy Efficiency
The Duro-Last PVC roofing system is engineered for energy efficiency, significantly reducing your restaurant’s HVAC expenses. Its white, reflective membrane deflects the sun’s heat, helping your HVAC system operate more efficiently and lowering energy consumption. Additionally, the insulation’s high R-value enhances temperature control by reducing heat transfer, keeping your restaurant cool during hot weather and warm during colder months.
Fire-Resistance
The PVC formulation incorporates fire-retardant chemicals that enhance its resistance to combustion, prevent the spread of flames and also makes it self-extinguishing, adding an extra layer of protection to your roof. Duro-Last roofing membranes meet or exceed major national fire and wind code requirements, as well as most required regional approvals throughout the country.
Low Maintenance
Duro-Last roofs require minimal maintenance however, it is still important to keep your roof maintained and clean to maximize the roof’s lifespan. Here are a few maintenance tips to do so :
- Inspect for leaks in the building after severe weather storms
- Minimize foot traffic as much as possible
- Conduct a roof cleaning 1-2 times per year, checking for screws, nails, sharp objects, or outside debris (especially if building is surrounded by a lot of trees/vegetation)
- Schedule roof inspection at 15 years mark

Top 5 Common Causes of Commercial Roof Leaks
Commercial leaks can cause significant damage, disrupt operations, and result in financial losses for businesses. Understanding the common causes of commercial leaks is crucial for effective prevention and timely intervention. In this blog post, we will explore the top five most frequent causes of commercial leaks. By gaining insights into these common causes, businesses can take proactive steps to safeguard their properties
Table of Contents
1. Open Penetrations on roof
Penetration on the roof refers to any hole that is made through your roof. Many commercial roofs have membrane-based material that can be easily penetrated with any sharp object such as a nail or knife.
Flat commercial roofs often feature a range of components, including roof vents, HVAC units, drains, gas lines, and pipes. These elements penetrate the roof’s membrane, creating openings or passages referred to as penetrations. Areas of penetrations should be properly sealed during the initial roof installation.
How Does It Affect My Roof?
Penetrations on your roof affect the integrity of your roof. Water infiltration occurs through the opening, subsequently traveling beneath the membrane until it locates a path within the building, ultimately leading to the occurrence of a leak.

2. Installation done improperly
A common cause of a leak is ultimately the material utilized not being installed correctly. It is important to hire a company that specializes in the material that you are installing on your flat roof.
How Does it Affect My Roof?
There have been many instances where we inspect a building and find that the roofer didn’t follow the material installation guidelines. Leaving the owner with more headaches as they are now stuck with multiple issues such as leaks.
3. Improper Drainage (ponding water)
First, Let’s talk about the importance of a proper Drainage system on your flat roof.
With flat roofs, you have to play the game a little differently in comparison to your typical traditional residential roof system. A Residential roof tends to have a slanted roof allowing the water to run down your roof onto the gutters. On a flat roof, however, you do not get that luxury since you are dealing with a low slope roof (aka a flat roof). This helps differentiate between the differences in water drainage on a flat roof compared to a slanted residential roof.
Slanted residential roof

How Does a Proper Drainage System Help My Roof?
If water lingers in one spot for too long, it puts excessive stress and weight on the roof. This becomes even more problematic if the roof is already older or compromised because it increases the chances of leaks. Moreover, the excess water can damage the roofing material, making it more prone to future leaks. Keeping a proper drainage system can help keep water from sitting on the roof.
If you are experiencing this issue please call a trusted roofing company to come out and inspect your roof to better help the direction of water to the proper location preventing the chances of leaks.

4. Poorly done Repairs
There have been multiple occasions where we go up to inspect a roof and we see repairs that have just been done poorly, causing a more significant issue in the long run. It is important to make sure you are resolving the issue on deck not just posing for a temporary fix or diy situation.
Common examples of improper repairs in commercial roofing:
- Band-aid fixes: Applying temporary sealants or patches without addressing the root cause, such as underlying roof defects or damaged membranes.
- Use of incorrect materials: Employing unsuitable or incompatible materials that do not provide adequate protection against leaks or weather elements.
- Lack of professional expertise: Attempting DIY repairs without proper knowledge and training can lead to improper techniques, ineffective repairs, and compromised roof performance.

5. HVAC System leaking
Checking HVAC systems for leaks is crucial for commercial buildings. It is common that a cause for leaks is not directly associated with any roof system but instead with the HVAC system. Certain areas of the HVAC system should be inspected to ensure effective leak detection. These include ductwork, connections and fittings, and condensate drain lines.
How can HVAC System compromise the integrity of my roof?
If the condensate pump in your AC system malfunctions or becomes dirty, it can lead to water leakage, potentially causing flooding in your attic or basement. The persistent presence of water creates a conducive environment for the growth of mold and mildew inside the unit, which can subsequently lead to clogging. By prioritizing HVAC leak detection and maintenance, businesses can enhance energy efficiency, maintain a healthy indoor environment, and prolong the lifespan of their HVAC systems.

What Is The Best Material For Flat Roofs? Residential Homes in Houston TX
What is the best flat roof material for my home?
With regards to the intense weather here in Houston Texas, many homeowners ask themselves the question as to what would be the appropriate material for my flat roof? Flat roofs are a different kind of ballgame compared to your traditional roofs, since they require more attention and can be more tedious to work with.
Down below we will discuss the different options that you as a homeowner have.
Our Disclaimer
There is not one flat roof system that is the “better option” for everyone . Flat roof systems vary and we as a company want to personalize your flat roof system depending on your situation.
Your decision as to what flat roof material you use is going to be based of these questions.
- What is your budget?
- What is the style of your home?
- What do you like as a homeowner?
- What does your decking look like?
Modified Torch
What is Modified Torch?
- Modified torch is a rolled membrane roofing system primarily made of asphalt. The construction resembles shingles but in a more flexible form and have an additional waterproof coating applied.
There are two different types of applications
- OPEN FLAME
Attached by melting the asphalt onto the roof (most secured option)
2. PEEL AND STICK
Attached simply the way it hears by peeling and sticking it onto the roof.
We as a company do not recommend the peel and stick method as it tends to leave many open seams.
TPO
What is TPO?
- (Thermoplastic Polyolefin) is a single-ply membrane used in both commercial and residential roofing.
PROS
Cost Effective – TPO roofs can come in at a more budget-friendly install
Energy Savings – TPO membrane comes in white, that reflects most of the intense Texas sunlight throughout the day. Keeping your building cooler.
What does the application process look like for TPO?
There are 2 most common applications
1. MECHANICALLY ATTACHED
The TPO material is applied by properly using fasteners to secure it down to the decking.
2. ADHESIVE
The TPO material is applied by using an adhesive like substance to attach the TPO onto the decking.
TPO does great with wind ratings.
TPO does very well as it is most found on your hotels, strip centers, office buildings and commercial/ residential buildings.
PVC
What is PVC?
- (Polyvinyl Chloride) is also a single-ply membrane used in both commercial and residential roofing.
What does the application process look like for PVC?
PVC has a similar application process to TPO
1. MECHANICALLY ATTACHED
The TPO material is applied by properly using fasteners to secure it down to the decking.
2. ADHESIVE
The TPO material is applied by using an adhesive like substance to attach the TPO onto the decking
A great system, however we most commonly see TPO over PVC in the Houston Area.
You can see PVC in many office buildings as well as other commercial/residential properties.
Seamless metal
What is seamless metal?
- Is a series of metal panels that are locked together at the seams or seamed mechanically.
PROS
What does the application process look like for Seamless Metal?
Seamless metal can only be attached for one way
Most commonly than not we do not see seamless metal roofs a whole lot in the Houston area.
Seamless metal roofs are most commonly installed in new construction homes rather than a roof replacement/repair.
What is the biggest problem when it comes to my flat roof having leaks?
INSTALLATION!!!!
Most often that not many flat roofs have leaks or other issues due to poor installation hurting the lifespan of these roofs.
When looking at hiring a contractor to fix your roof make sure they specialize in flat roofs as they tend to be more difficult, tedious and acquire more experience to work with.

Duro-Last vs TPO | Which Is Better?
Is TPO or Duro-Last a better roofing system? Duro-Last is the better roofing system yet will be more expensive. In this blog post, we are going to break it all down for you from a contractor’s perspective that installs and repairs both roofing systems.
Material Differences
Duro-Last and TPO almost look identical both being white single-ply membranes. If you dive deeper into the material, what really sets them apart is their chemical compound.
Is TPO or Duro-Last a better Material? Duro-Last develops a higher quality material with a better chemical compound making them the better material. Their material is more expensive, and it really shows when we compare material vs. material.
Duro-Last Material Breakdown
Duro-Last is composed of PVC film laminated to both sides of a reinforcement fabric (weft-inserted scrim).
PVC Film: Proprietary thermoplastic PVC
formulation of resins, plasticizers, stabilizers,
biocides, flame retardants, and U.V. absorbents
Weft-Inserted Scrim: An 18 x 14 polyester fabric construction with weft insertion, composed of 840 x1000 denier threads, provides superior tear and puncture resistance. The polyester thread is treated to prevent wicking.
Duro-Last itself is a type of PVC roofing system and a Brand. Duro-Last carries manufacturing plants all over the United States and the closest one to Houston is located in Dallas.
In order to install a Duro-Last roofing system, you need to directly place an order through their company. This means you have to be certified through them and have an account with them.
Each Duro-Last system is custom fabricated for your roof which is why they can’t sell them at roofing supply stores.
TPO Material Breakdown
TPO (Thermoplastic Polyolefins) compounds are resin blends of polypropylene and un-crosslinked EPDM rubber and polyethylene
TPO is not a brand it is a type of material. There are different brands that create TPO membranes such as:
TPO material can be ordered from your local supplier because they are purchased in rolls. If you are here in Houston, you are able to find most brands at ABC Supply or Commercial Distribution Specialists.
How is each material installed?
Duro-Last & TPO are similarly installed most commonly using these methods:
Mechanically Attached
Fully Adhered
Both roofing systems utilize the same roofing accessories and similar Insulation types (Fan-Fold 1/2″ and Polyiso).
The biggest difference between the two is the way they come. TPO is a rolled good that comes in either 6′ x 100′ or 10′ x 100′ while Duro-Last is a prefabricated membrane made specific to the dimensions of your roof that just gets unfolded at the jobsite.
Due to Duro-Last being prefabricated, there are less seams to weld meaning there is a less likelihood for a leak happening in the seams.
When you are installing TPO you need to have a 6″ overlap between the rolls to go ahead and weld the seams. You have more seams to weld when installing TPO and more of a potential for possible leaks in the future.
That doesn’t mean TPO is hard material to install. It just means that TPO is harder to install when compared to Duro-Last.
Does Duro-Last or TPO cost more?
Duro-Last: They require you to order through the Duro-Last portal and use only Duro-Last accessories. The material itself is more expensive versus TPO membranes. Since you have to order the material to get it prefabricated there is a wait time and more delivery costs fees.
TPO: It is usually readily available at your local roofing supply and the material itself is less. Making it the more affordable option!
WARNING FOR OUR BUSINESS OWNERS
Both materials are great and if they were both installed correctly the Duro-Last system will give you several years more than a TPO system.
Issues come from the material not being INSTALLED CORRECTLY not from the material itself!
Find a great roofing company that can show you their past jobs and explain to you the breakdown of how they are going to install everything, but most importantly the warranty they are offering as a company not just material warranty.
4 Most Common Causes of TPO Leaks
What are the 4 most common causes of TPO Leaks? As an owner, you find out that your building is having roof leaks & the first thing you want to do is find out what is causing it.
We wanted to create a blog/video to help you understand what we see as a roofer. A TPO roof can be repairable and lasts you for more years to come.
NOTE: The solutions that are recommended are going to need a professional roofer trained in installing/repairing TPO material. When it comes to TPO roofs it is NOT A DIY PROJECT.
1. Penetrations/Damaged Material
One of the most common TPO roof leak causes is penetration to the membrane. TPO is a membrane and can be easily penetrated with any sharp object such as a nail or knife.
When it rains, the water will travel inside through the hole and run underneath the membrane until it finds a way through the building inside.
Damaged Flashing
Solutions
Penetration in the TPO membrane is usually the easiest to repair. They are repaired with TPO patches. The breakdown of the process is this:
- We clean and prep the area
- Find the penetrations
- Weld a TPO patch over the penetration
2. Ponding Water
Flat roofs are meant to have ponding water for up to 48 hours. If the water is staying there for more than 48 hours it usually means it is a draining issue. Once the water is staying for too long it will eventually degrade the TPO material and add a significant amount of weight to a roof which can cause structural damage.
If you have ponding water over penetrations then the water will slowly damage the decking & insulation below leading to a more expensive repair or even a full replacement.
Solutions
The best way to prevent pooling is to ensure proper installation & immediate inspections once you find a possible roof leak. Flat roofing should not be completely level, we install necessary slops to direct water towards the drainage.
3. Incorrect Installation
Roofing materials must be properly installed to prevent leaks. Any type of roofing requires proper training, but with TPO there is extensive knowledge of installation & roof repair understanding that only an experienced professional would know. TPO is a newer roofing material that calls for specialized expertise during installation.
There have been many times we come out to inspect a building where the roofer did not install the material according to guidelines. Yes, maybe the owner saved some money at first but now they are dealing with leaks & have to call another roofing company to fix the issues.
Incorrect Installation of Parapet walls
Due to adhesive of parapet wall & not mechanically fastened
Incorrect Installation of Flashing
No termination bar was installed & instead just sealed with caulking
Incorrect Installation of Flashing
Solutions
Correct Installation of Flashing
Installation issues can vary from being a small repair to a big repair. For issues like these, you will need to hire a skilled professional to inspect the roof to determine if a repair or replacement is needed.

4. Degraded Material
Every roof wears down over time, even with regular maintenance and repairs. The average lifespan of a TPO roof is 20-30 years. Once you hit the 20-year mark, the material will start to degrade.
In the photo below the TPO roofing material is old & has started to crack.
Solutions
There is a chance that all it needs is a simple repair to make your roof last several more years with no issues. Once the whole roof is having multiple leaks and the material is old then it is time to consider a replacement to save you more money in the long run.
4 Reasons Why You Should Install a TPO Roof
Installing a TPO Roof System can be a great investment for your property
Are you searching for a durable yet cost-effective flat roof system for your commercial building? A TPO(Thermoplastic Polyolefin) is what we would recommend! Not only does it increase the longevity of your roof but can also help make your building more energy efficient. In this blog, we will go over 4 reasons Why you should install a TPO Roof.
Do You Need A New Flat Roof System?
Are you a business owner, who has a flat roof? Then you most likely already have a single-ply membrane roofing system or considering one for the future. There are two types of membranes to choose from: TPO and EPDM.
TPO stands for thermoplastic polyolefin. It’s a single-ply roofing membrane that is one of the fastest growing commercial roofing systems on the market. TPO roofing systems are made up of a single layer of synthetics that can be used to cover flat roofs.
How Much Does A TPO Roof Cost?
Based on the Industry standard in the Houston area, you can expect to pay anywhere from $500 and $1,200 per Square for a TPO roof system, this cost does include material, labor and a warranty of some type. At HHH Roofing, we are always ready to provide free and accurate estimates to answer all your TPO roofing questions, and to get a personalized estimate for your flat roof building.
Example:
If you have 50,000/SQ.FT that equals 50 Squares.
A TPO Roof Replacement for 50 squares will cost between $25,000 – $60,000.
NOTE: In 2021, we have seen an unprecedented labor shortage as a side effect of the COVID-19 pandemic. The demand for materials has skyrocketed. As a result, materials prices may be higher (we have been getting a 5-7% almost monthly) than reported in this article and lead times may be longer than usual.
Benefits of TPO Roofs
With all of TPO’s great benefits, it makes sense why so many Houston businesses are choosing this material for their commercial roofing needs. A TPO roof system is primarily used on flat roofs, it is vital to hire a professional TPO roofing contractor to install the roof system to ensure all goes well during heat welding and a successful roofing installation.
1. Energy Efficient
The most common TPO has a white membrane that reflects the sun’s energy(UV Rays) back to the atmosphere so much so that whenever we install TPO our team has to wear sunglasses. Commercial spaces can be large, requiring several resources to keep it warm in the winter and cool in the summer. With TPO roofing, the TPO material will result in energy and cost savings for your building.
Before we install the TPO, there is the insulation. When it comes to insulation it comes in all sorts of sizes. For example we have fan fold insulation that is about 1/2″. We can also use ISO insulation that come in 1″, 2″, 3″, etc. The insulation also helps with energy efficiency protecting your building from losing as much heat or cool air.
2. Cost Effective
Every single roof is an investment! Relative to other commercial roofing options, it is not as expensive as you think yet it will still last you a long time(25-30 Years)!
The reason for this is because of the easy installation. The TPO material comes in rolls that are 10 Feet Long and are mechanically attached to the building. This easy installation means savings on labor costs.
3. Durability
Because if consists of a rubber compound, TPO has a flexible membrane that is impervious to mold, rot and tear impact.
Reasons why we like TPO vs. EPDM roofing is because with TPO we weld the seams instead of just using adhesive. Welding the seams together is what also gives TPO that longevity of lasing 25 years.
A TPO roof system is built to drain the water so there is no ponding water unlike a Modified Bitumen Roof.
4. Multiple Options (Fits Different Budgets)
- Thickness of TPO
- 45 Mil
- 60 Mil
- Insulation
- Fanfold Insulation
- Iso 1″
- Iso 2″
- Iso 3″
- Color Options

A TPO roof system is primarily used on flat roofs, it is vital to hire a professional TPO roofing contractor to install the roof system to ensure all goes well during heat welding and a successful roofing installation.
How does a roofing company price a TPO roof repair? Here are the 3 different price points for TPO repairs:
Minor TPO Roof Repair
Price Point: $600-$1,000
Minor repairs are the most common. This will include punctures to the membrane itself, welding new patches to the TPO, or replacing flashing. It’s usually the small details on a roof system.
Even though they are minor repairs, we recommend hiring a certified TPO roofing contractor. We cannot tell you enough how many projects we had to fix simply because it was poorly installed.
Moderate Roof Repair
Price Point: $1,000-$3,000
A moderate repair will typically be fixing either an area that another contractor did incorrectly or fixing multiple punctures. It’s a smaller job that will only take 1 day but it does require a little more work than just fixing welding 1 simple patch.
Take for example the picture below, it was a job where another contractor put cement around the area. The issue is that cement doesn’t work well on a TPO roof system. The owner was having leaks so we had to remove the cement and weld new patches to the area.
Major Roof Repair
Price Point: $3,000+
A major repair will be replacing an entire section usually also due to incorrect installation.
When it is a major repair you might consider a full TPO replacement just to save you money in the long run.
