When you’ve got a flat or low-slope roof, the last thing you want is a system that traps heat or wears out fast. TPO roofing gives you a clean, reflective surface that keeps things cooler and holds up year after year. At On Top Roofing, we install it with the kind of detail-focused care your building deserves.
TPO, or thermoplastic polyolefin, is a single-ply roofing membrane that’s tough, flexible, and built to reflect sunlight. It’s a favorite for commercial properties and flat-roof sections on homes because it keeps temperatures down, creates a smooth finish, and seals out water without a lot of fuss. If your roof takes on full sun or supports rooftop units, TPO can handle it without cracking or shrinking.
Why Homeowners Choose TPO
Keeps heat out and energy costs down
TPO’s bright surface helps bounce sunlight away from the roof, lowering the temperature of your building and giving your HVAC system a break. It’s one of the easiest ways to reduce cooling costs without changing a single thing inside your space.
Stronger seams, fewer leaks
Instead of using adhesives, TPO seams are welded together with heat. That creates one solid surface that resists separation over time. It holds tight even at the roof edges and around units—where leaks like to sneak in.
Built to handle tough roof use
Things like foot traffic and rooftop equipment can take a toll on some roofs, but TPO roofing materials are up for the task. It’s naturally resistant to grease, chemicals, and scuffs from regular maintenance visits. That makes it a solid option for everything from restaurants to utility spaces and anywhere in between.
Our TPO roofing process
Step 1
Roof inspection and estimate
First, we take a close look at the existing roof and talk through your goals. If TPO’s the right match, we’ll send over a detailed quote.
Step 2
Planning the install
We map out the membrane layout, insulation, and fastening method to make sure the system performs the way it should from day one.
Step 3
Tear-off and prep
Old materials come off, and we take care of any soft spots or problem areas in the decking before laying down the new system.
Step 4
Membrane installation
Our crew welds each seam with precision, sealing edges and corners so the finished roof is smooth, secure, and ready for the long haul.
Step 5
Final walkthrough
Before we call it done, we’ll walk the roof with you, answer any questions, and make sure everything looks right and cleans up well.
With proper installation and care, TPO roofs typically last 20–30 years. Their welded seams and durable surface help them resist wear, making them a long-term solution for flat and low-slope roofs.
Yes. While TPO is a popular choice for commercial properties, it’s also great for residential flat or low-slope areas like home additions, garages, and porch covers.
Instead of adhesives, TPO seams are heat-welded to create a continuous surface. This method keeps seams from separating over time, even at roof edges and around rooftop equipment.
TPO is low-maintenance. Occasional inspections and basic cleaning are enough to keep it in good shape. It also resists damage from foot traffic, grease, and common rooftop chemicals.
Yes. Small punctures or damage can be repaired by welding a patch into place, restoring the membrane’s watertight seal without replacing the entire roof.
Absolutely. TPO stands up well to the wear and tear from maintenance traffic and is resistant to grease and chemicals, making it ideal for rooftops with HVAC systems or other equipment.
We offer a thorough inspection and consultation to evaluate your needs. If TPO is the best fit, we’ll recommend the right installation method for your space and budget.
