In recent years, commercial roofing systems feature TPO, or thermoplastic polyolefin, coatings. These single-ply and rubber roofing membranes typically appear on flat roofs, including office buildings, apartment complexes, and school roofing systems. Below, learn more about TPO roofs to determine if this material is right for your commercial needs.

Major Benefits 

Low installation and maintenance costs make a TPO roof an economical choice. Its unique durability adds to its cost-effectiveness. TPO roofing materials offer excellent dirt and mold resistance, and will not scratch, tear, corrode, or sustain punctures. The rubber membrane also expands and contracts in reaction to weather changes, unlike other single-ply products that can crack and allow water infiltration.

White TPO roofs increase energy efficiency because they reflect rather than absorb heat, which saves money in utility costs and premature HVAC system replacements. The building safety also rises due to Class A fire resistance, and there are numerous installation options to select from. This includes plate bonding, adhesion, and mechanical attachment.

Specific Drawbacks 

If you’re considering this type of roofing system, it is integral to do your research. There’s a wide variety of TPO products available, some of which lack quality and deteriorate quickly. Those with cheap laminate coatings, for example, tend to shrink and crack fast. Also, it is important to keep in mind that thicker products do not equal increased durability, as thin and thick coatings wear at about the same rate. Since TPO rolls are not sizeable in regards to width, you’ll need to purchase multiple rolls to cover your roof. This can result in seam cracks without efficient sealing. However, an experienced roofing contractor can ensure that there will be complete coverage. 

Main Uses

TPO membranes are often installed on commercial and industrial roofing systems with flat roofs and offer residential applications, though warranties can differ. The coatings also get utilized when EPDM and other single-ply coatings cannot withstand the elements or any time a roofing system is exposed to grease and other contaminants that shorten its lifespan. TPO coatings offer grease resistance in addition to protecting against water intrusion and fire damage.
