Understanding EPDM Roofing
What is EPDM Roofing?
EPDM is a type of synthetic rubber roofing membrane that is widely used in both residential and commercial roofing applications. It is known for its excellent resistance to UV radiation, ozone, and weathering, making it an ideal choice for a variety of climates. EPDM roofing is available in a range of thicknesses, with the most common being 45 mils and 60 mils. It also comes in two colors: black and white, with white EPDM offering additional reflectivity, which can help reduce cooling costs.

Tools and Materials Needed for EPDM Roofing Installation
Before you begin the installation process, you’ll need to gather the necessary tools and materials. Here’s a list to get you started:
Tools:
- Utility knife or scissors
- Measuring tape
- Chalk line
- Roller
- Broom or leaf blower
- Paintbrushes (for applying adhesive)
- Ladder
- Safety gear (gloves, safety glasses, etc.)
Materials:
- EPDM roofing membrane (ensure you have enough to cover the entire roof area)
- EPDM adhesive (water-based or solvent-based, depending on your preference)
- EPDM seam tape (for sealing the seams between membrane sheets)
- Termination bar or edge flashing (to secure the edges of the membrane)
- EPDM primer (for preparing the surface before applying the seam tape)
- EPDM cover tape (for reinforcing seams and flashings)
Preparing the Roof Surface
Inspect and Clean the Roof
Before installing the EPDM membrane, it’s crucial to prepare the roof surface properly. Start by inspecting the roof for any damage, such as cracks, holes, or loose materials. Any existing issues should be repaired before proceeding with the installation.
Once the roof is in good condition, clean the surface thoroughly. Use a broom or leaf blower to remove any dirt, debris, and loose particles. A clean surface is essential for ensuring that the adhesive bonds properly to the roof.
Measuring and Cutting the Membrane
Accurate measurements are critical when installing EPDM roofing. Measure the dimensions of your roof and cut the EPDM membrane to fit, leaving an extra 6-12 inches on each side for overhang. This overhang will be trimmed after the membrane is fully adhered to the roof.
To ensure the membrane lays flat and without wrinkles, it’s advisable to lay it out on the roof for a few hours before installation. This allows the material to relax and makes it easier to handle during the installation process.
How To Install EPDM Roofing: Step-by-Step Guide
Step 1: Apply the Adhesive
With your membrane cut and ready, it’s time to apply the adhesive. Start by folding back half of the membrane, exposing the roof surface beneath. Using a paintbrush or roller, apply a thin, even layer of adhesive to both the roof surface and the underside of the membrane. Be sure to follow the manufacturer’s instructions regarding adhesive coverage and drying time.
Once the adhesive has become tacky (but not dry), carefully roll the membrane back into place, pressing it down firmly to ensure a strong bond. Use a roller to smooth out any air bubbles or wrinkles, working from the center outward to the edges.
Step 2: Secure the Seams
After the first half of the membrane is adhered to the roof, repeat the process on the other half. Once the entire membrane is in place, it’s time to secure the seams between the sheets.
Apply EPDM primer along the seam where the two membrane sheets meet. After the primer has dried, apply EPDM seam tape along the seam, ensuring it’s centered over the joint. Use a roller to press the seam tape firmly into place, removing any air bubbles and ensuring a watertight seal.
Step 3: Trim the Excess Membrane
With the membrane fully adhered and the seams secured, you can now trim the excess material from the edges. Use a utility knife or scissors to carefully cut the overhang, leaving about 1-2 inches of membrane extending past the edge of the roof.
Step 4: Install Edge Flashing or Termination Bar
To secure the edges of the membrane and prevent water infiltration, install edge flashing or a termination bar along the roof perimeter. This step is crucial for ensuring the longevity and performance of your EPDM roof.
Attach the flashing or termination bar to the roof edge using appropriate fasteners, making sure it’s securely anchored. Once installed, apply a bead of EPDM sealant along the top edge of the flashing or termination bar to create a watertight seal.
Step 5: Inspect and Finish
After completing the installation, take the time to inspect the entire roof, checking for any areas that may require additional attention. Look for air bubbles, wrinkles, or loose seams, and address these issues immediately to prevent future problems.
Once you’re satisfied with the installation, allow the adhesive to cure fully, which may take several days depending on the weather conditions. During this time, avoid walking on the roof to prevent damaging the membrane.
Maintenance Tips for EPDM Roofing
Regular Inspections
To ensure the longevity of your EPDM roof, it’s important to conduct regular inspections. Check the roof for signs of damage, such as cracks, tears, or loose seams, and address any issues promptly. Regular inspections can help you catch minor problems before they turn into major repairs.
Cleaning the Roof
EPDM roofs are relatively low maintenance, but occasional cleaning is necessary to keep them in good condition. Use a soft-bristle broom or a leaf blower to remove debris, and if necessary, wash the roof with a mild detergent and water solution. Avoid using harsh chemicals or abrasive tools, as these can damage the membrane.
Repairing Damage
If you notice any damage to your EPDM roof, such as a puncture or tear, it’s important to repair it as soon as possible to prevent leaks. EPDM repair kits are available and typically include patches, adhesive, and primer. Follow the manufacturer’s instructions to ensure a proper repair.
