There are three types of installation methods for EPDM;
Fully Adhered, Mechanically Attached, and Ballasted.
The fully adhered, and mechanically attached systems are done the same as the TPO and PVC systems, except the seams are adhered together vs being heat welded.
Ballasted systems are loose laid, and weight-based with the gravel or stone on top. In areas where certain items may be dropped from balconies on hotels, high rise condos, a ballasted system would be preferred.
In areas where there might be windows that overlook the roof, EPDM can be a great option versus TPO or PVC as it is black and not a bright white that can be hard to look at with the sun reflecting.
The time frame for install can vary greatly based on the size of the roof, how much flashing is needed, type of substrate, (multiple layers of insulation board and coverboard), and application method for the membrane. We do try our best to set a timeline of repairs, however at times outside factors may delay the install process such as weather-related delays.
Warranties for EPDM roof systems are very similar to the warranties that are offered with TPO and PVC and require manufacture approval for 20yr NDL (No Dollar Limit) warranties. workmanship, and material defects. Even if the roofing contractor that installs the roof goes out of business, the manufacturer will still honor the warranty and find a qualified contractor to address any issues that may arise. The manufacturer can offer this type of warranty as they inspect the roof before, during and after the install process to ensure it is being installed to their specifications.
EPDM roofs can usually last 15-20 years and in certain cases longer if properly maintained. Some of the factors that can affect the roof longevity are weather such as wind or hail, membrane thickness (40, 60, 80 mil), and consistently maintaining the roof over its lifespan.
EPDM roofs are extremely energy-efficient, will help you and your business save money on heating and cooling costs and its an environmentally-friendly choice. Coupled with the ease of maintenance, quick repairs, and fire resistance, EPDM is a popular choice for many of our customers.
