High-performance fire retardant EPDM membrane built for NJ's demanding climate. Mule-Hide FR EPDM delivers 465% ultimate elongation, outstanding ozone resistance, and proven weatherability — installed by NJ Roofing across commercial and residential flat roofs in Essex, Hudson & Union counties.
Mule-Hide FR 60 and 90 mil EPDM membranes are non-reinforced, high-performance single-ply systems manufactured to meet or exceed ASTM Standard Specification D 4637. The Fire Retardant (FR) formulation is specially designed to inhibit the spread of flame and meet or exceed all code body testing criteria.
The elastomeric properties of Mule-Hide EPDM compensate for thermal shock and building movement — critical for NJ's extreme temperature swings between winter and summer. Available with factory pre-applied in-seam tape for faster, more consistent seam placement in the field.
Specially formulated to inhibit flame spread — meets or exceeds all code body testing criteria for FR roofing membranes.
Zero cracks or crazing after 16,500 hours of xenon-arc UV weathering — far exceeding specification requirements.
Pre-applied in-seam tape reduces labor cost and ensures consistent, void-free seam placement on every installation.
Unlike TPO which requires heat welding robots or generators, Mule-Hide EPDM installs with standard tools — reducing job costs.
ASTM G21 testing shows zero fungi growth — eliminating the black streaking and biological degradation common on older membranes.
All values sourced directly from the Mule-Hide FR EPDM Product Data Sheet (PDS 09-1310). Typical values exceed specification minimums.

Factory in-seam tape — faster installation
Key performance advantages that make Mule-Hide FR EPDM a strong choice for NJ commercial and residential flat roofing projects.
Zero cracks or crazing after 16,500 hours of accelerated UV weathering (xenon-arc) — over 5× the minimum specification requirement. Designed for NJ's four-season extremes.
No cracks after 168 hours at 100 pphm ozone at 50% strain (ASTM D 1149). EPDM's inherent ozone resistance far exceeds thermoplastic alternatives.
Can be installed over a wide variety of roof deck types — concrete, metal, wood, and insulation substrates — making it ideal for NJ's diverse commercial building stock.
A variety of Factory Mutual ratings, Underwriters Laboratories classifications, and Miami-Dade approvals are available — meeting NJ building code requirements across all jurisdictions.
Unlike TPO welding systems, Mule-Hide EPDM requires no robots, heat-welding equipment, or generators — reducing installation cost and equipment dependency on every NJ project.
Factory pre-applied in-seam tape reduces field labor, ensures consistent seam coverage, and eliminates the variability of field-applied tape — delivering a more reliable finished roof.
NJ Roofing installs Mule-Hide FR EPDM using both approved methods — selected based on your building deck, wind requirements, and budget.
Maximum wind-uplift, ideal for most NJ applications
Fast coverage, economical for large commercial roofs
Both systems — critical installation steps
