EPDM Rubber Roofing Membrane

Protect your flat roof with confidence using our high-quality EPDM rubber roofing membrane collection. Whether you're working on a shed, garage, extension, or full flat roof replacement, this durable, weather-resistant material is a popular choice across the UK for both domestic and commercial roofing projects.

Long-Lasting Performance for UK Roofs

Known for its impressive 50-year life expectancy and resistance to harsh weather, EPDM flat roof membrane provides a reliable, waterproof barrier that won’t crack, split or blister over time. Flexible and easy to install, it's ideal for new builds or refurbishments—especially when working around upstands, vents, or awkward roof details.

Simple to Fit, Built to Last

EPDM membrane is supplied in a single piece wherever possible, reducing the need for joints and lowering the risk of leaks. It’s compatible with timber, concrete, and other approved surfaces, making it a go-to choice for professionals and DIYers alike. Pair with our range of adhesives, primers, and edge trims for a complete system that’s built to last.
