How to Choose: Rubber Roofing vs TPO in NJ

EPDM has been installed on NJ commercial buildings since the 1960s, giving it the longest proven track record of any single-ply membrane. We have 50-year-old EPDM roofs still functioning in Essex County. TPO entered the market in the 1990s and has proven itself over 25+ years, with modern formulations resolving the early quality concerns.

For risk-averse building owners, EPDM's multi-decade track record provides confidence. For owners focused on performance and efficiency, TPO's modern technology offers measurable advantages in energy savings and seam reliability.

EPDM is black, absorbing solar heat. TPO is white, reflecting it. In Essex County summers, this difference translates to 15-30% lower cooling costs for TPO-covered buildings. EPDM's heat absorption is marginally beneficial in winter but does not offset the summer penalty for air-conditioned buildings.

Seam technology differs fundamentally. EPDM seams use adhesive tape or liquid adhesive, both of which can degrade over time. TPO seams are heat-welded, creating a bond stronger than the membrane itself. This single difference drives much of TPO's growing market dominance.

Choose EPDM if you want the longest-proven track record, your building has minimal cooling loads, budget is the primary concern ($4.50-$7.50/sq ft vs TPO at $5.50-$9/sq ft), or your roof has ponding water issues. Choose TPO for energy efficiency, superior seam technology, modern aesthetics, or if you are pursuing green building standards.

Both materials are available from every major commercial roofing manufacturer and every qualified Essex County contractor can install either system competently.
