EPDM, or ethylene propylene diene terpolymer, roofing is a popular choice for flat and low-sloped roofs due to its durability, affordability, and ease of installation. If you are considering installing an EPDM roof, it is important to know the process and steps involved to ensure a successful installation. In this article, we will provide the ultimate guide to installing an EPDM roof.

Step 1: Preparation

Before beginning the installation process, it is important to prepare the roof surface. This includes removing any debris, cleaning the surface, and repairing any damaged areas. It is also important to ensure that the surface is completely dry before beginning the installation process.

Step 2: Measuring and Cutting the EPDM Membrane

Next, you will need to measure and cut the EPDM membrane to fit the roof surface. It is important to measure accurately and ensure that the membrane is cut to the correct size to avoid any issues during installation.

Step 3: Applying Adhesive

Once the membrane is cut to size, you will need to apply adhesive to the roof surface. It is important to use the correct type of adhesive for your specific EPDM membrane and to follow the manufacturer’s instructions for application.

Step 4: Installing the Membrane

After the adhesive is applied, you can begin installing the EPDM membrane. It is important to work carefully and systematically to avoid any wrinkles or bubbles in the membrane. You should also ensure that the membrane is properly aligned and fits snugly against the edges of the roof surface.

Step 5: Sealing the Edges

Once the membrane is installed, you will need to seal the edges to ensure that the roof is completely watertight. This can be done using a special EPDM sealant or tape, which is applied around the edges of the roof and any seams in the membrane.

Step 6: Finishing Touches

Finally, you can add any finishing touches to your EPDM roof, such as installing flashings or drainage systems. It is important to ensure that all components are properly installed and sealed to prevent any leaks or damage to your roof.


Installing an EPDM roof can be a relatively straightforward process if you follow the correct steps and procedures. By preparing the surface, measuring and cutting the membrane accurately, applying adhesive correctly, installing the membrane carefully, sealing the edges, and adding any finishing touches, you can ensure a successful EPDM roof installation that will provide reliable protection for years to come.
