Commercial roofing systems, explained
Most commercial and low-slope roofs in Texas use one of three systems — TPO, EPDM, or modified bitumen — and the right choice depends on your building's slope, sun exposure, and budget.
TPO (thermoplastic polyolefin) is a reflective, heat-welded single-ply membrane popular in Texas specifically because of its performance against intense sun exposure. EPDM (a synthetic rubber membrane) is durable and cost-effective but less reflective. Modified bitumen is an asphalt-based, multi-layer system known for strong durability on complex or heavily-trafficked roofs. All three are commonly used across Texas commercial properties; the right one depends on your specific building.
The local reality in the Texas Panhandle, South Plains, and DFW
Texas summer heat makes reflectivity a real performance factor for flat commercial roofs, not just an energy-efficiency talking point — TPO's white, reflective surface is one reason it's become the most common choice for new commercial installations across Amarillo, Lubbock, and DFW.
Sal's experience
Sal Morales Roofing's commercial division works with all three systems and gives property owners and facility managers a straightforward comparison based on the specific building, rather than defaulting to whichever system is easiest to install.
Real evidence, not a sales pitch
A Sal Morales Roofing crew at work — the same installation standards apply across residential and commercial roofing systems.
The same installation standard — proper seam welding, correct insulation layering, and attention to drainage and ponding areas — applies regardless of which system is used, and it's what actually determines how long a commercial roof lasts.

Common questions
Which commercial roofing system lasts longest?
All three can perform well for decades with proper installation and maintenance — lifespan depends more on installation quality, drainage, and maintenance than on which system is chosen.
Is TPO the best choice for every building?
TPO is a strong default for reflectivity and cost, but EPDM or modified bitumen can be better choices depending on roof traffic, slope, and specific building needs.
Do commercial roofing systems need different maintenance than residential?
Yes — flat and low-slope commercial systems require attention to seams, drainage, and ponding water that residential sloped roofs don't.
