We install and repair TPO roofing systems for commercial properties throughout Denton and Denton County. Whether you are replacing an aging membrane, repairing storm damage, or installing a new system on a commercial property, our team handles every stage of the project correctly.
TPO, or thermoplastic polyolefin, is a single-ply membrane roofing system commonly used on flat and low-slope commercial roofs. The membrane is heat-welded at seams to create a watertight bond and can be installed using multiple methods depending on the building type and project requirements. TPO is white or light-colored by default, meaning it reflects rather than absorbs solar radiation, an important characteristic in a climate as warm as North Texas.
Denton summers put serious heat stress on commercial roofing systems. TPO’s reflective surface reduces the amount of solar heat absorbed by the roof, which can lower cooling costs meaningfully for buildings with large roof areas. It is also resistant to UV degradation, puncture, and the kind of chemical exposure common on buildings with HVAC equipment or kitchen exhausts. For many commercial property owners in the area, TPO offers the best combination of performance and cost among single-ply membrane options.
TPO can be installed using three primary methods: mechanically attached, where the membrane is fastened through its edge to the roof deck; fully adhered, where the membrane is bonded directly to the insulation below; or ballasted, where a loose-laid membrane is held in place by stone. The right method depends on the building’s structure, wind uplift requirements, and local code. We review the appropriate approach for your property before any work begins.
A properly installed TPO roof in North Texas typically lasts 15 to 25 years, depending on membrane thickness, installation quality, and maintenance. Keeping drains clear, inspecting seams and penetration flashings annually, and addressing any punctures or membrane damage promptly are the key maintenance tasks. We also recommend an inspection after any significant hail event, since hail can damage the membrane in ways that are not always visible without close examination.
TPO problems can develop gradually before they show up as interior leaks. These are signs that your Denton commercial property may need professional attention.
