Flat Roofing Systems We Offer

EPDM Rubber Roofing

EPDM (ethylene propylene diene monomer) is a synthetic rubber membrane designed for flexibility, UV resistance, and longevity. It’s one of the most proven roofing materials on the market—ideal for commercial and industrial buildings.

EPDM Benefits:

Lasts 30–40+ years with proper maintenance

Resistant to UV rays, hail, and temperature swings

Low maintenance with fewer seams than traditional systems

Compatible with rooftop equipment and drainage systems

Can often be installed over existing roofing for cost efficiency

Offers reflective, energy-efficient performance—keeping your building cooler in summer. It’s heat-welded for watertight seams and ideal for large, open roof areas.

TPO Roofing

TPO (thermoplastic polyolefin) offers reflective, energy-efficient performance—keeping your building cooler in summer. It’s heat-welded for watertight seams and ideal for large, open roof areas.

Modified Bitumen Roofing

A modern version of traditional asphalt roofing, modified bitumen combines strength and flexibility. It’s layered for extra durability and performs well in both hot and cold climates.
