EPDM
Roofing.
Proven EPDM rubber roofing membranes with 50+ year performance. Ideal for Colorado's climate extremes.
EPDM (Ethylene Propylene Diene Monomer) is a synthetic rubber roofing membrane with a proven 50+ year track record on commercial and industrial buildings. Its exceptional resistance to temperature extremes, UV exposure, and ozone makes it particularly well-suited to Colorado's challenging climate conditions.
EPDM's rubber composition gives it outstanding flexibility across a wide temperature range — from Colorado's summer highs above 100°F on rooftop surfaces to winter lows well below zero. Unlike some membrane systems that become brittle in cold weather, EPDM remains pliable and maintains its waterproofing integrity through freeze-thaw cycles. EPDM is also highly resistant to hail impact, which is a critical consideration in Colorado's hail-prone climate. Modern EPDM systems are available in both black and white (fleece-backed) versions, with white EPDM providing the energy efficiency benefits of a reflective roof.
ZMAC Construction installs EPDM roofing systems in fully adhered, mechanically attached, and ballasted configurations. We work with leading EPDM manufacturers including Carlisle SynTec, Firestone, and Johns Manville, and our installers are certified to apply these systems to manufacturer warranty standards. EPDM is an excellent choice for buildings where long-term durability and low maintenance are the primary priorities.

FAQ.
EPDM installation involves: preparation of the existing roof deck or substrate; installation of insulation board to achieve the required R-value; installation of the EPDM membrane in the specified attachment method; seaming of all laps using EPDM tape or liquid adhesive; installation of all flashings, penetration details, and edge metal using EPDM flashing materials; and final inspection. ZMAC provides a detailed installation plan before work begins and performs quality control inspections throughout the project to ensure all seams and details meet manufacturer specifications.
EPDM roofing project timelines depend on roof size, complexity, and weather conditions. A typical 10,000–20,000 square foot commercial roof takes 3–7 business days to complete. We provide a detailed project schedule before work begins and communicate any weather-related delays promptly. EPDM can be installed in cooler temperatures than some other membrane systems, which can be an advantage during Colorado's shoulder seasons.
