ClassicBond EPDM Rubber Membrane

ClassicBond EPDM roofing membrane is a flexible rubber sheet used as part of a compatible flat-roof waterproofing system. EPDM has a different installation approach from traditional bituminous roofing felt, and can be useful on extensions, garages and outbuildings when the deck, adhesive and details are designed together.

Flexible EPDM rubber membrane for flat-roof waterproofing

The current product options list thicknesses of 1.2mm and 1.52mm, plus selectable lengths of 3m, 4.57m and 6.1m. Confirm how the size selector relates to the required sheet dimensions and the supplied roll before ordering. The old description mentions long-term lifespan and certification; these should be checked against current supplier documentation for the exact product.

Buying and measuring advice

Measure the roof including upstands, parapets and edge returns. Allow enough material for termination and detailing, rather than ordering only the flat plan area. Identify the substrate, board type, edge trims, outlets and any pipe penetrations. Choose a complete system with approved adhesives, tapes, primers and accessories.

Installation and care considerations

Follow ClassicBond's current instructions for deck preparation, sheet relaxation, adhesive selection, laps and secure perimeter detailing. Avoid trapped moisture within the roof build-up and assess vapour control where required. Professional installation may be appropriate on complicated or high-exposure roofs. Do not assume the membrane alone makes all junctions watertight.

Roof Tiles & Fittings:

We recommend ordering an additional 10% of roof tiles to allow for any breakages that may occur during delivery or handling. Roof tiles are naturally fragile, and having a few extra on site helps prevent delays and ensures your roofing project can be completed without interruption.
