TPO Roofing
TPO roofing is one of the most popular choices for flat and low-slope commercial roofs. It delivers strong waterproofing, solid durability, and great UV resistance—perfect for Florida heat and heavy rain cycles.
At Magnum Roofing & Restoration, we install and repair TPO roof systems with clean welding, proper drainage planning, and detail-focused flashing work. We keep it simple: we build the system to last, not to “look okay” for a year.

What Is TPO Roofing?
TPO stands for Thermoplastic Polyolefin. It’s a single-ply membrane used on flat and low-slope roofs. Installers heat-weld the seams, which creates a strong bond and helps the roof resist leaks.
TPO works well on many commercial buildings because it combines durability with reflective performance, which helps reduce heat load on the roof surface.

Benefits of TPO Roofing
Heat-welded seams for leak resistance
We weld TPO seams using heat to create a fused bond. That bond helps the membrane stay watertight over time.
Strong UV resistance
TPO handles sun exposure well, which matters a lot in Florida. It helps reduce surface breakdown caused by constant UV.
Great for flat and low-slope roofs
Many commercial roofs need a membrane that manages moisture and supports drainage planning. TPO fits that need well.
Helps support energy performance
Many TPO systems use reflective surfaces to reduce heat absorption, which can support better cooling performance in the building.

TPO Roof Installation
A TPO system needs more than a membrane. The performance depends on the full build: substrate prep, insulation layout, seam weld quality, edge detailing, and penetration flashing.
What we focus on during installation
- Roof inspection to confirm the right system approach
- Surface prep and moisture checks
- Insulation planning for performance and drainage
- Clean seam welding and consistent weld quality
- Strong flashing details at edges and penetrations
- Drainage support to reduce ponding water risk

TPO Roof Repair
We repair TPO roofs by targeting the real failure point. We inspect seams, flashing, penetrations, drains, and edge terminations. Then we fix the issue with the correct method for the system.
Common TPO roof issues
- Open or weakened seams
- Leaks at penetrations (HVAC, vents, curbs)
- Edge termination failures
- Punctures from foot traffic or debris
- Drainage problems and ponding water zones

TPO vs. Modified Bitumen
TPO and modified bitumen are both strong options for low-slope roofs. The best choice depends on your building, roof conditions, and performance goals.
TPO is often chosen for
- Reflective performance in hot climates
- Heat-welded seam design
- Modern single-ply commercial roof builds
Modified bitumen is often chosen for
- Multi-layer membrane strategies
- Durable systems with different reinforcement options
- Roofs that benefit from a tougher “built-up” feel

FAQs
Is TPO good for Florida?
Yes. TPO works well in hot, sunny climates because it resists UV and supports reflective performance. Proper installation and drainage planning matter most.
Can you repair a TPO roof instead of replacing it?
Yes. If the roof system is still in decent shape, repairs can solve leaks and extend roof life. We inspect first and recommend the best option.
Does TPO roofing stop ponding water?
TPO can handle water exposure, but ponding water often points to drainage or slope issues. We check drains, scuppers, and roof layout during inspection.
