The history of EPDM roofing runs deep. With over 50 years on the market and billions of square feet produced and installed, Carlisle SynTec’s EPDM has a proven track record as one of the most resilient membranes in the single-ply roofing industry today.
As time goes on and the construction industry evolves, more sustainable structures are becoming the norm. Building codes are increasingly robust and are placing a greater emphasis on protecting your building from Mother Nature’s wrath. Your roof system plays a huge part in achieving compliance and serves as the first line of defense against hail, wind, and other damaging elements. This is where EPDM’s sustainability and durability come into to play. Sustainability and resiliency are some of the strongest attributes of Carlisle’s EPDM membranes, and EPDM’s durability allows us to offer a high-end, 30-year Total System Warranty that guarantees long-term performance. Below are the enhancements that Carlisle SynTec requires when upgrading to a 30-year EPDM system:
30-Year EPDM Enhancements
The thicker and more durable 90-mil EPDM, 75-mil reinforced EPDM, or 145-mil FleeceBACK®
EPDM are required; fully adhered, mechanically fastened, or ballasted designs are available. The thicker membranes will provide greater long-term performance and superior resistance to weathering. Please note, 45-mil and 60-mil membranes are not eligible for 30-year Total System Warranties.
Membrane splices are one of most important parts of any roofing system and utilizing our Factory-Applied Tape™
means more watertight seams and fewer warranty claims. On a 30-year EPDM system, Carlisle requires membrane with 6”-wide Factory-Applied Tape or 6” SecurTAPE™
to be installed at all seams and end laps. The 6”-wide tape has greater peel and sheer strength and results in a stronger bond. Please note, 3” factory-applied or hand-applied tape on 30-year warranties must be stripped in with Pressure-Sensitive Cured Cover Strip.
The Flashing Details:
In addition to seams, flashing details are critical to preventing issues where rooftop penetrations are tied in to the field membrane. On 30-year EPDM systems, Carlisle requires specific details to be double-wrapped or covered with two layers of flashing.
Below is a list of these details:
U = Universal (applies to all 30-year systems)
A = Adhered Systems Only
B = Ballasted Systems Only
MF = Mechanically Fastened Systems Only
