Commercial Roofing

The leading single-ply and low-slope options are TPO, EPDM, and modified bitumen. TPO's heat-welded seams and reflective surface suit energy-conscious buildings; EPDM has a decades-long track record and good cold-weather flexibility; modified bitumen resists punctures on high-traffic roofs. The best choice depends on your building's drainage, rooftop traffic, and budget, which we evaluate on-site.

Both are proven low-slope membranes that can last decades, but they differ in a few ways: TPO is typically a reflective white membrane with heat-welded seams, while EPDM is a black rubber membrane usually joined with tape or adhesive seams. TPO's reflectivity can lower cooling costs in hot climates like Central Texas, while EPDM has the longer historical track record. We help you weigh energy performance, seam durability, and cost.

Expected service life is roughly 20-30 years for TPO and EPDM and about 15-20 years for modified bitumen, but installation quality and maintenance matter more than the material label. Twice-yearly inspections, keeping drains clear, and repairing seams and flashing promptly are the most effective ways to reach the roof's design life.

Yes. A scheduled program of inspections, drain and debris cleaning, and documented minor repairs prevents small issues from becoming costly interior-damage events and helps keep warranties valid. Documented maintenance history is also increasingly important for insurance, since carriers may scrutinize inspection records after a storm claim.

Ponding — water that remains on the roof more than a day or two after rain — usually points to drainage or slope issues and can stress the membrane and shorten its life over time. Persistent ponding should be evaluated, because ongoing standing water is a common driver of low-slope roof deterioration and failure. We assess drainage as part of any commercial inspection.
