We install GAF commercial roofing systems on Houston buildings, including TPO, modified bitumen, and reflective coatings built for Gulf Coast heat and storms.

GAF Commercial Roofing Systems We Install in Houston
We install GAF commercial roofing systems on low-slope buildings across the Houston metro, from distribution warehouses off the Sam Houston Tollway to office and retail properties around the Galleria and Westchase. GAF's commercial line is broad, and that breadth is the point: a single manufacturer covers single-ply TPO, multi-ply modified bitumen and built-up assemblies, and liquid-applied reflective coatings. On a Gulf Coast roof, having that range under one system lets us match the assembly to the building instead of forcing every roof into the same membrane.
Most of our Houston work lives in three GAF families: EverGuard TPO for reflective single-ply roofs, modified bitumen systems for multi-ply durability, and roof coatings for restoring and extending serviceable roofs. Each one earns its place in a different situation, and the climate here, sustained heat, large hail, heavy rain, and coastal wind, tends to push the decision pretty clearly once we have walked the roof.
GAF EverGuard TPO for Heat and Reflectivity
TPO is the membrane we specify most on Houston low-slope roofs, and GAF's EverGuard line is a core part of that. The white reflective surface turns away the solar energy that pounds a flat roof through a long Houston summer, when the rooftop bakes for months and the space below pays for it in cooling. That reflectivity lowers the heat load and eases the strain on rooftop HVAC units that run nearly year-round in this climate.
We install EverGuard in multiple thicknesses based on exposure. On roofs that take foot traffic, carry heavy equipment, or face serious hail risk, we step up to the heavier 80-mil membrane for a thicker weathering surface. The heat-welded seams are what make TPO dependable in a wet climate: the sheets fuse into a continuous membrane with no adhesive bond line to fail when water ponds after one of Harris County's heavy rains.

GAF Commercial Roofing Systems in Houston, TX

Not every roof is a single-ply candidate. On buildings that need a tough, redundant membrane, on roofs with heavy traffic, or where an owner wants the multi-layer reliability of an asphalt-based system, we install GAF modified bitumen. These systems build up multiple reinforced plies into a thick, robust membrane that handles abuse and gives real margin against punctures and impact.

The redundancy matters on a Gulf Coast roof. With multiple layers bonded together, a surface that takes hail damage or a puncture still has plies beneath it holding the water out, which buys time to find and repair the damage before it reaches the building. We can finish these systems with a reflective surfacing or a coating to recover some of the summer heat benefit that a dark asphalt roof would otherwise give up in this climate.

GAF Roof Coatings for Restoration

A lot of Houston commercial roofs do not need a full tear-off, they need restoration before the heat and sun finish them off. GAF's reflective roof coatings let us extend the life of a sound but aging roof by sealing the surface, restoring reflectivity, and adding a fresh weathering layer without the cost and disruption of a complete replacement. On the right roof, that is the most cost-effective move an owner can make. Coatings are especially useful here because of the heat. A reflective coating over a tired, heat-absorbing roof cuts the surface temperature, lowers the cooling load, and adds years of service. We evaluate the existing roof first, because a coating only makes sense over a substrate that is still structurally sound and reasonably dry; if the roof is too far gone or holding moisture, replacement is the honest answer and we will say so.

Wind, Hail, and the Edge Details

On the Gulf Coast, the membrane is only part of the story. Wind gets under a roof at the perimeter and corners first, and a failed edge can strip a field that was otherwise sound. We build GAF assemblies with engineered edge metal, termination details, and enhanced fastening in the high-uplift perimeter and corner zones, because that is where coastal wind concentrates its force when a storm system crosses Harris County.
