What is TPO roofing?
Thermoplastic polyolefin (TPO) is a single-ply rolled roofing material made from plastic and recycled rubber. TPO is only suitable for flat or low-sloped roofs and is eco-friendly because its white surface reflects heat. TPO roofing falls between EPDM and PVC in price and durability.
How long does a TPO roof last?
TPO roofs last 10 to 25 years on average, depending on the material quality and thickness. Coating and sealing a TPO roof may lengthen its lifespan.
Can you paint a TPO roof?
Yes, you can paint a TPO roof. Make sure to clean the roof thoroughly first and choose a compatible paint type, such as latex, elastomeric, or epoxy paint.
