Modified Bitumen Roofing in Denver, CO

Modified bituminous membrane roofing combines the proven reliability of built-up roofing with modern polymer technology for superior performance and longevity.

What is Modified Bitumen?

Modified bitumen roofing is an asphalt-based roofing system that has been enhanced with polymer modifiers (typically APP or SBS) to improve its performance characteristics. This technology has been used in the commercial roofing industry for over 50 years.

The membrane consists of asphalt reinforced with fiberglass or polyester and modified with rubber or plastic for added flexibility and durability. A granular surface coating provides UV protection and enhanced fire resistance.

Features and Benefits

Modified bitumen offers time-tested performance with modern enhancements

Proven Performance: Modified bitumen roofing has been used successfully for over 50 years in the commercial roofing industry. Its time-tested performance gives building owners confidence in their investment.

Multi-Ply Protection: Modified systems can include up to 3 plies of membrane, providing exceptional waterproofing and redundancy. Multiple layers mean multiple lines of defense against leaks.

Easy Repairs: Modified bitumen systems are easy to repair and maintain. Damaged areas can be patched quickly, and the material is compatible with most repair products.

Installation Methods

Modified bitumen can be installed using several methods, each suited to different project requirements:

Torch Applied: Heat is used to melt the underside of the membrane, creating a bond with the substrate

Cold Adhesive: Special adhesives bond the membrane without open flame

Self-Adhered: Peel-and-stick membranes for fast, safe installation

Hot Mopped: Traditional application using hot asphalt
