How it works
From measuring to a finished roof
EPDM is one of the most DIY-friendly flat roof systems: no heat, no torches, and cold-applied adhesives.
1. Measure the deck
Measure the flat roof deck, length and width. The kit or calculator adds the extra for upstands and edges.
2. Choose your kit
Pick a ready-sized kit or build one to measure. The price you see is the price you pay.
3. Free delivery
Dispatched within one working day, delivered free anywhere we deliver in the UK.
4. Fit it with our guides
Free step-by-step fitting guides for decks, trims, corners and outlets.
Not sure what to order?
Send us your roof measurements or a photo on WhatsApp and we will tell you which kit or membrane size fits, before you pay anything.

Questions before you buy
How do I measure my roof?
Measure the flat deck itself, wall to wall or edge to edge, in metres. Do not add anything for overhangs or upstands: each kit page lists the deck size it covers, and the calculator adds the extra membrane for you.
Will my membrane arrive in one piece?
Yes. It is supplied as one sheet with no on-site joining required. Larger sizes may contain factory-made joins, but the membrane is delivered as one complete sheet.
How long does EPDM last?
EPDM rubber roofing has a life expectancy of 50+ years when fitted correctly. See our lifespan guide for what affects it.
Can I fit it myself?
Yes. EPDM is cold-applied with water-based and contact adhesives, with no torches or heat. Our installation guide and shed fitting guide walk through each step.
How much does delivery cost, and how fast is it?
UK delivery is free on every order. Orders are dispatched within one working day.
