Commercial Modified Bitumen Roofing Across Texas
Meis Roofing provides commercial modified bitumen roofing installation, repair, replacement and maintenance for businesses and property owners across Texas. Modified bitumen is a multi-layer low-slope roofing system known for durability, waterproofing and resistance to heavy rooftop traffic.
We work with property managers, facility managers, building owners and general contractors throughout DFW, Austin, San Antonio, Central Texas and Houston.

What Is Modified Bitumen Roofing?
Modified bitumen roofing uses reinforced asphalt-based membrane sheets engineered for commercial flat and low-slope roofs. The membranes are modified with polymers to improve flexibility, strength and weather resistance.
These systems are commonly installed in multiple plies and can be used for both new construction and roof replacement.
APP vs. SBS Modified Bitumen Roofing
APP Modified Bitumen
APP-modified membranes use plastic modifiers that improve heat resistance and durability. They are commonly installed using torch-applied or other manufacturer-approved methods.
SBS Modified Bitumen
SBS-modified membranes use rubber-like modifiers that improve flexibility and allow the membrane to expand and contract with temperature changes. SBS systems can be installed using hot asphalt, cold adhesive or self-adhered products depending on the assembly.
I would replace the current technical wording about “glass-reinforced polyester” unless you specifically want that level of product detail.
Modified Bitumen Installation Methods
- Torch-applied systems
- Cold-applied adhesive systems
- Self-adhered membrane systems
- Hot asphalt applications where appropriate
The appropriate installation method depends on the roof assembly, project specifications, building use, manufacturer requirements and site conditions.

Modified Bitumen Roof Repair
Modified bitumen roofs can develop problems from membrane splits, blistering, punctures, deteriorated seams, failed flashing and moisture intrusion. Meis Roofing inspects the affected area and surrounding roof system to identify the source of the problem and determine the appropriate repair.
Repairs may include membrane patches, flashing corrections, seam repairs or replacement of damaged sections.
Modified Bitumen Roof Replacement
When a modified bitumen system has widespread deterioration, saturated insulation, recurring leaks or extensive storm damage, replacement may be more practical than continued repairs.
Meis Roofing evaluates the membrane, insulation, drainage and deck condition before recommending replacement options.
Modified Bitumen Roof Maintenance
Regular inspection and maintenance can help identify cracking, blistering, open seams, flashing failures, drainage issues and other conditions before they become larger problems.
Modified Bitumen vs. Built-Up Roofing
Modified bitumen and built-up roofing are both asphalt-based systems commonly used on commercial low-slope roofs. Built-up roofing typically uses multiple layers of asphalt and reinforcing felts, while modified bitumen uses factory-manufactured membrane sheets with polymer modifiers.
Both systems can provide strong durability and waterproofing when properly designed and maintained.
