Coommercial Roofing Waterproofing Specialists
At Waterbrothers we are proud to be associated with a company, that more than 50 years ago, revolutionized the commercial roofing industry with the Carlisle EPDM membrane.
With 1.4 Billion square meters installed worldwide Carlisle has cemented themselves as the world leader in waterproofing systems.
Top 10 reasons to choose Carlisle EPDM
Carlisle EPDM is time-tested in real-world conditions. Black EPDM roofing systems have been used for more than 50 years. Testing of 30-year old EPDM shows tear, tensile strength and flexibility meet or exceed ASTM standards
Superior weather resistance
Carlisle EPDM has advanced resistance to UV exposure, heat and mold.
ASTM G155 for Xenon Arc + 41,580 kj/m2 for black EPDM
ASTM D573 for heat aging = 68 weeks at 240°F
ASTM G21 for fungi = zero ( no growth )
Carlisle EPDM’s nominal 1.14mm of weathering protection is significantly greater than most plastic based sheets. A 20 year material warranty is available on the 1.14mm and 30 year warranty on the 1.524mm*
Superior Hail Resistance
Numerous studies and real-world experience confirm that Carlisle EPDM has a 465% elongation ( ASTM D412 ) and weathering resistance results in superior hail damage resistance and UL 2218 Class 4 rating.
The solar benefits of Black EPDM help to reduce heating costs in cooler climates while the cross-linked nature of Carlisle EPDM can handle the heat in hot climates.
EPDM’s dark color surface helps to melt frost, dew and ice that can create slippery conditions on reflective waterproofing. The black Carlisle EPDM reduces a roofs water load and dries more quickly that a reflective roof.
Carlisle EPDM is the most dimensionally stable membrane, remaining flexible in extremely cold conditions. Per ASTM D5279-08 EPDM is more flexible at 0 degrees F than TPO at 100 degrees F.
The solar thermal benefits of black Carlisle EPDM also help to reduce potential condensation issues. Undetected condensation in a roofing assembly can negatively affect the performance of paper insulation facers, weakening the bond between insulation and adhesive and can have a detrimental effect on the insulations R-value, resulting in reduced thermal efficiency.
Carlisle’s labor saving seaming technology and pressure sensitive flashings improve the quality and consistency of seams. Electrical or gas seaming equipment consumes natural resources and is dependent on the applicator using correct speed, temperature, and pressure to avoid false or cold welds or seams.
At Waterbrothers we stock the 3m, 6m, and 9m wide x 30m long panels, this reduces the number of seams when compared to other products on the market, which also reduces pooling on the roof deck.
The 3 EPDM Roofing Waterproofing Systems
Adhered EPDM Roofing System
The EPDM is adhered directly to the substrate using a bonding adhesive that is specifically formulated to bond the single-ply membrane to just about any surface.
With 50+ years of real-world testing, there is no other product that can protect your home like Carlisle EPDM.Unlike our competitors with membranes of only 1.2m – 2m wide, our large 9m x 30m panels can waterproof many homes with zero or very few seams. Fewer seams = fewer pooling areas = longer lifespan = no leaks.
Inverted EPDM Roofing System
This is the preferred roofing system especially designed for high-traffic roofs.
It consists of a layer of loose laid single-ply EPDM with a insulation board covered by a geotextile and then a ballast added to hold the whole system down. This system is quick to install and can be retro fitted to existing buildings that can accommodate the load.
The inverted system makes the building super energy efficient in both hot and cold climates.
Ballasted EPDM Roofing System
Because of its fast installation and insulation properties, ballasted systems are an extremely economical choice.
The EPDM membrane is loose laid on the substrate with a geotextile for added protection, and then a ballast consisting of stone or pavers is used to hold the membrane in place.
The ballast helps to shield the membrane from the elements, thus extending the life of the membrane.
