Flat Roof Services in Houston — TPO, EPDM, and Modified Bitumen
Flat roof repair in Houston starts at $500. Full flat roof replacement ranges from $8 to $20 per square foot depending on membrane type and building access. Houston Roofing Pros installs and maintains TPO, EPDM, and modified bitumen systems for commercial buildings, townhomes, condos, and warehouse conversions across Greater Houston.
Houston is one of the largest flat-roof markets in the South. Galleria/Uptown office towers, Montrose townhomes, EaDo warehouse conversions, Spring Branch strip centers, and Pasadena industrial buildings all rely on flat or low-slope roofing systems that standard residential shingle contractors cannot handle.
Flat Roof Systems We Install and Repair
TPO (Thermoplastic Polyolefin) is the top recommendation for Houston flat roofs. The white reflective surface bounces solar heat rather than absorbing it — critical in a market where flat roofs reach 180+ degrees in summer. TPO is heat-welded at seams (not glued or taped), creating bonds stronger than the membrane itself. Lifespan: 15 to 30 years. Energy Star rated, qualifies for cool roof tax incentives.
EPDM (Ethylene Propylene Diene Monomer) is a durable rubber membrane excellent for low-budget repairs and reroof applications where existing substrate is in good condition. Black EPDM absorbs heat, making it less ideal for Houston's summer conditions, but it remains the most cost-effective option for shaded roofs. Lifespan: 20 to 30 years.
Modified Bitumen is an asphalt-based system applied in multiple layers with torch, cold-process adhesive, or self-adhering methods. Excellent compatibility with existing built-up roofs on 1970s and 1980s commercial buildings. Common on Spring Branch strip centers and Sharpstown apartment complexes. Lifespan: 10 to 20 years.
Built-Up Roofing (BUR) maintenance — We do not install new BUR systems, but we maintain and repair existing BUR on older commercial buildings throughout the Houston area.
