What is the difference between modified bitumen and built up roofing systems?

Built up roofing uses alternating layers of asphalt and felt, while modified bitumen combines asphalt with rubberized or plasticized polymers for added flexibility and strength. Built-up roofing is heavier and takes longer to install.

What types of modified bitumen membranes do you offer?

We install APP membranes, SBS membranes, and hybrid mod-bit systems, depending on your building’s needs, climate, and performance goals.

How is modified bitumen installed?

Modified bitumen roofing can be installed with hot asphalt, cold adhesive, heat welding, or mechanical attachment, depending on project requirements.

Is modified bitumen a good fit for low-slope roofs?

Yes, that's where it excels. Modified bitumen roofing is designed specifically for low slope and flat roof applications and offers superior protection and drainage.

What is the average life expectancy of a mod bit roof?

With proper installation and maintenance, a modified bitumen roofing system can last 20–30 years or more.

Is modified bitumen resistant to UV rays and extreme temperatures?

Absolutely. SBS modified membranes offer excellent UV resistance and flexibility under cold temperatures or elevated temperatures, making an excellent choice for Texas commercial buildings.

Modified bitumen roofing is one of the most dependable roofing materials for Texas commercial and industrial buildings with low slope or flat roofs.

What is Modified Bitumen?

Modified bitumen (“mod-bit” for short) roofing is a great option for commercial buildings. They’re a multi-ply asphalt-based roofing system, reinforced with rubber or plastic for enhanced durability. Modified bitumen sheet materials can be installed with cold adhesive, heat welded, or mechanically attached. They’re highly waterproof, damage-resistant, UV-resistant, and flexible, with a long service life when properly installed and maintained.

EXCEPTIONAL MATERIALS & INSTALLATION

Commercial Benefits of Choosing Modified Bitumen

Modified bitumen roofing systems are a proven solution for commercial roofs needing strength, longevity, and performance in all types of weather conditions. With flexibility in their installation methods and design, they’re a great choice for flat or low-slope roofs.

Durability & Lifespan

Mod bit roofing systems are some of the most durable options available. They resist punctures, foot traffic, fire, and wind-driven debris for long-term reliability.

Energy Efficiency

Modified bitumen roofing systems can improve energy efficiency with reflective coatings, helping to reduce heat absorption and lower cooling costs.

Weather Performance

SBS modified bitumen membranes perform well in all weather conditions. They remain flexible in cold weather and resist extreme temperatures.
