Galveston’s Modified Bitumen Roofing Experts
Looking for a durable, flexible, and weather-resistant flat roofing system? At Galveston Roofing Group, we specialize in modified bitumen roof installation, repair, and maintenance for commercial and residential properties throughout Galveston, Texas. Designed to perform in harsh coastal environments, modified bitumen is an excellent roofing solution for long-term protection.
What Is Modified Bitumen Roofing?
Modified bitumen is a multi-layer membrane roofing system engineered for flat and low-slope roofs. It combines asphalt with polymers—typically SBS (Styrene-Butadiene-Styrene) or APP (Atactic Polypropylene)—to enhance strength, flexibility, and UV resistance. These membranes are reinforced with fiberglass or polyester for increased performance and durability.
Main Types of Modified Bitumen Roofing:
- SBS-Modified Bitumen – Rubber-like flexibility, ideal for roofs with frequent temperature fluctuations
- APP-Modified Bitumen – More rigid and UV-resistant, excellent for high-sun exposure areas
Installation methods include torch-down, cold adhesive, and self-adhered applications, depending on the project’s needs and safety considerations.

FAQs About Modified Bitumen Roofing Galveston
Why is modified bitumen ideal for commercial buildings?
It’s durable, waterproof, and highly resistant to UV rays and storms—perfect for flat or low-slope commercial roofs in Galveston.
Can it be combined with other systems?
Yes. Modified bitumen works well in hybrid systems with TPO, EPDM, or metal roofing for enhanced protection and energy savings.
How is it different from standard asphalt?
Modified bitumen includes polymers for added flexibility and strength, making it superior in durability and temperature tolerance.
Is it fire-resistant?
APP-modified membranes and coatings can offer fire-resistant properties—ideal for safety compliance in commercial facilities.
How does it hold up to foot traffic?
Very well. It’s a great choice for rooftops with HVAC units or frequent maintenance access.
