EPDM Roof Installation Process Explained in Simplified 4 Steps

EPDM roof installation, just like nearly all roofing-related projects, is best to be handed over to professional due to its high degree of risk. However, if you’re interested in knowing the summarized setting up process of this durable and cost-effective synthetic rubber roofing membrane material, then you’d be able to read about it below.

Here is the simplified version of EPDM roof installation guide:

Roof deck preparation

The EPDM roof installation process is started by cleaning up the roof deck from any grime and oil, drying any moisture that can disrupt the adhesive, as well as sanding plywood or OSB board’s edges to provide a protective barrier for the membrane.


Install drip batten and drip edge

Next step is to set up the drip batten into the fascia surrounding the roof to lengthen the decking that direct water drains into the gutter. Afterwards, set up the drip edge to align with the batten’s curved upper part to make sure that the water won’t get into the edge of the roof and cause erosion.


Arrange the EPDM membrane

The rubber membrane layer should be large enough to cover the roof entirely and overhang the roof edge and exterior walls. While preparing the roof deck, uncover the EPDM membrane and spread it over the roofing area where it’s going to be installed, then let it sit for about half an hour.

After the EPDM membrane has relaxed, carefully roll it back so around half part of the rocking deck is exposed. Use a paint roller to apply the bonding adhesive and leave 6-inch area around border. Install the membrane before the adhesive is drying up. Note that the drying up process goes faster on hot days, so estimate the number of areas you’ll work on. Sweep out the pocket air using a push broom to boost the bond after the roof membrane is set up. Continue until all parts of the membrane are attached.


Spread the finishing

Now it’s time to apply adhesive to the 6-inch area around border. Afterwards, use pressure-sensitive elastoform flashing to seal the corners and create waterproof seals for the ventilators. Seal the edges again using silicone sealant to make the membrane moisture-resistant. By the end, trim the membrane to take of the excess.

While the process might seem easy enough to be tackled on one’s own, it is still highly recommended to hire professional to carry this project as they have the proper experience and required tools to do so. Contacting professional to conduct EPDM roof installation also helps to prevent improper work and optimize its lifespan.
