EPDM Roofing for Flat & Low-Slope Commercial Properties

Durable, Flexible, Cost-Effective

EPDM (Ethylene Propylene Diene Monomer) roofing is a single-ply synthetic rubber membrane commonly used on flat and low-slope commercial roofs. Known for its exceptional durability and flexibility, EPDM provides reliable, long-term protection against harsh weather conditions.


EPDM membranes are manufactured in large sheets and installed with minimal seams, reducing potential leak points. Systems can be fully adhered, mechanically attached, or ballasted, depending on your building’s structure and performance needs.


Its black membrane naturally absorbs heat, which can be beneficial during colder New Hampshire winters, while still providing excellent resistance to ultraviolet (UV) exposure, ozone, and extreme temperature fluctuations.


New Hampshire’s varying climate is tough on commercial roofing systems. When professionally installed and properly maintained, an EPDM roofing system can last 20 to 30 years or more.
