Flat Roofing & TPO
Roll roofing and TPO for low-slope homes, additions, porches, carports and commercial buildings across South Texas.
Flat and low-slope roofs work differently from a pitched roof. Water does not run off fast, so seams, edges and drains do all the work, and one weak spot can turn into a leak after the next heavy rain. Across San Antonio and South Texas you see them on additions, back porches, carports, older homes and plenty of commercial buildings.
We install two main systems on low-slope roofs. Roll roofing is a practical, lower-cost option for smaller areas like additions, porches and carports. TPO is a single-ply membrane, usually white or light colored, with heat-welded seams, that reflects a lot of the summer sun and is widely used on commercial buildings and larger flat roofs. We help you pick the one that fits the building and the budget.
Most flat roof problems come from water that sits too long, worn seams and poor edge or wall flashing. Before we install, we look at how the roof drains and where water collects, and we take care with edges, walls and every pipe penetration.
