EPDM Membrane 4.57m
High quality EPDM roofing membrane supplied in 4.57 metre width, ideal for large flat roof areas requiring minimal seams. Durable and flexible waterproofing solution with a long service life of 50+ years. Suitable for residential and commercial projects across Dublin and all Ireland.
Sizing Recommendation:
EPDM membranes are supplied in fixed roll widths and are cut to your required length. Simply enter the roof length needed when ordering, and we will cut the membrane to size before dispatch.
We recommend allowing at least 100 mm extra membrane on each side of the roof (200 mm added to both roof length and width) to accommodate upstands, edge details and secure waterproofing.
Example: For a roof measuring 4.00 m × 5.00 m, we recommend ordering a membrane suitable for a finished size of approximately 4.20 m × 5.20 m. In this case, you would select a 4.20 m wide membrane and enter a quantity of 6.0 m. Membrane supplied will be 4.20 m × 6.00 m.

EPDM Membrane 4.57m is a premium synthetic rubber roofing membrane designed for flat and low-slope roof waterproofing. The extra-wide 4.57 metre roll significantly reduces the number of joints and seams, improving installation efficiency and long-term watertight performance.
Manufactured from high-grade EPDM rubber with a typical thickness of approximately 1.14mm, this membrane provides excellent resistance to UV radiation, ozone, extreme temperatures and standing water. When correctly installed, EPDM roofing systems are widely recognised for their durability and expected service life of 50+ years.
Its superior flexibility allows easy installation around outlets, skylights, parapets and roof penetrations, making it ideal for both new build and refurbishment projects.
