If you have a predominantly flat roof, you need to know about TPO roofing. TPO is a chemical acronym for ThermoPlastic-Olefin. Basically, it’s a somewhat stiff, white plastic that is rubber-like.

Flat roofing is an often misunderstood area, perhaps because most people never see a flat roof and always see slanted roofs with tile or shingles. The two most commonly used and least expensive flat roof types are known as torchdown and hot tar.
