Question 1

What is TPO roofing?

Accepted Answer

TPO (Thermoplastic Polyolefin) is a single-ply reflective membrane used for flat and low-slope commercial roofs. It is heat-welded at the seams for superior waterproofing and reflects solar heat to reduce cooling costs.

Question 2

How long does a TPO roof last?

Accepted Answer

A properly installed TPO roof lasts 20–30+ years. Manufacturer warranties range from 15 to 30 years. Proper installation is critical to achieving the full lifespan.

Question 3

Is TPO roofing energy efficient?

Accepted Answer

Yes. TPO's white reflective surface reflects up to 90% of solar heat, reducing rooftop temperatures by up to 60°F. This typically lowers cooling costs by 10–30%.

Question 4

How much does a TPO roof cost?

Accepted Answer

TPO roofing typically costs $5–$10 per square foot installed, depending on membrane thickness, insulation, and building complexity. We offer wholesale pricing on all materials.

Question 5

What thickness of TPO should I choose?

Accepted Answer

We recommend 60-mil or 80-mil TPO for commercial applications. 60-mil is suitable for most buildings, while 80-mil provides extra durability for high-traffic or high-exposure roofs.

Question 6

Can TPO be installed over an existing roof?

Accepted Answer

In many cases, yes. If the existing roof is structurally sound and meets building code requirements, TPO can be installed as a recover system, eliminating tear-off costs.

Question 7

How are TPO seams sealed?

Accepted Answer

TPO seams are heat-welded using hot-air welding equipment. This creates a bond that is actually stronger than the membrane itself — far superior to adhesive or tape-based sealing methods.

Question 8

Is TPO roofing puncture-resistant?

Accepted Answer

TPO offers good puncture resistance, especially in 60-mil and 80-mil thicknesses. For roofs with heavy foot traffic or rooftop equipment, we can add walkway pads for extra protection.
