Product Information

Full details

The ClassicBond EPDM Membrane (1.2mm, 3.05m wide) is designed for professional roofers and experienced DIY enthusiasts who require a durable, weather-resistant solution for flat roof projects. Its primary benefit is the seamless, single-ply coverage it provides, which significantly reduces the risk of leaks compared to traditional felt roofing. However, users should be aware that the material's width and weight require careful handling and proper adhesive application to ensure a wrinkle-free, long-lasting installation.

FAQs

Can I install this over an existing roof?

It is generally recommended to remove old roofing materials to ensure a clean, stable, and rot-free surface for the EPDM.

Is the membrane fire-rated?

ClassicBond EPDM systems are designed to meet standard building regulations for fire safety, but you should verify local requirements for your specific roof build-up.

How do I join two pieces of membrane?

You must use a specialized EPDM seam tape and primer system to ensure a watertight bond between two sections.

Can the membrane be walked on?

Yes, it is suitable for occasional foot traffic for maintenance purposes, though heavy use may require additional protective decking.

What is the expected lifespan of this product?

When installed correctly, EPDM membranes can last in excess of 50 years due to their high resistance to weathering.

Troubleshooting

Membrane shows wrinkles during installation

Ensure the membrane has been allowed to relax for at least 30 minutes before bonding. Use a heavy roller to smooth out the material from the center toward the edges.

Poor adhesion to the deck

Verify the substrate is completely clean, dry, and free of dust or moisture. Ensure the correct amount of contact adhesive was applied to both surfaces.

Pros and Cons

Pros

  • High durability and long service life
  • Seamless single-piece coverage for most residential roofs
  • Excellent resistance to extreme temperature changes
  • UV and ozone resistant properties
  • Relatively easy to install compared to multi-layer torch-on systems

Cons

  • Material is heavy and can be difficult to maneuver alone
  • Requires specific EPDM-compatible adhesives
  • Substrate must be perfectly clean and dry for successful bonding
  • Limited width to 3.05 meters may require seaming on very large commercial buildings

Setup, Compatibility & Care

To prepare for installation, ensure the roof deck is dry, smooth, and free of debris. Always verify that all adhesives and cleaning agents used are specifically formulated for EPDM systems, as solvent-based products not approved for EPDM can damage the material.

For care, the membrane is largely maintenance-free. It is recommended to perform a visual inspection twice a year to ensure that edge trims are secure and that the membrane remains free of sharp debris. Cleaning should be done with mild soap and water if necessary, avoiding harsh chemicals or petroleum-based products.
