🏠 WHY 1.2MM IS THE PERFECT CHOICE FOR YOUR PROJECT

The 1.2mm thickness is the UK's most popular EPDM specification — engineered to deliver the ideal balance of durability, flexibility and value for domestic and light-commercial flat roofs. Thicker than budget 0.9mm and 1.1mm alternatives, it offers significantly better tear resistance, longer life expectancy and easier handling — without the premium price of 1.5mm commercial-grade membrane.

Need extra durability for foot traffic or commercial use? See our 1.5mm Heavy Duty EPDM range. For everything else — sheds, garden rooms, extensions, garages, porches and outbuildings — 1.2mm is the proven specification recommended by UK roofers.

❓ FREQUENTLY ASKED QUESTIONS

Q: What thickness do I actually need — 1.2mm or 1.5mm?
A: For 95% of domestic projects (sheds, garden rooms, extensions, garages, porches), 1.2mm is ideal. Choose 1.5mm only for commercial roofs, foot-traffic areas or where extra puncture resistance is required.

Q: Is 1.2mm EPDM strong enough for the UK climate?
A: Yes — 1.2mm BBA-certified EPDM is engineered to perform from −40°C to +120°C and resists UV, ozone, hail and high winds. It is the UK's most installed thickness for domestic flat roofs.

Q: How much should I add for overlaps and trims?
A: Add a minimum of 150mm to every edge (so 300mm extra on width and length total). For example, a 3m × 4m roof needs a 3.3m × 4.3m membrane.

Q: Can I install it myself?
A: Absolutely — 1.2mm EPDM is the most DIY-friendly roofing membrane available. Most domestic installations are completed in a single day by a competent DIYer.

Q: Do you supply adhesives, trims and tools?
A: Yes — we stock the complete EPDM system including water-based deck adhesive, contact adhesive, primer, edge trims, seam tape and rollers.

Q: What's the difference between this and ClassicBond / Skyguard / Firestone?
A: All UK 1.2mm EPDM membranes are manufactured to similar specifications under BBA certification. The key differences are price, delivery, support and cut-to-size flexibility — areas where we lead the market.

Q: Does it come with a guarantee?
A: Yes — the membrane carries a manufacturer warranty backed by BBA certification and proven 50+ year service life.

Q: What if I order the wrong size?
A: Each piece is cut bespoke to your order, so please measure carefully and add 150mm to each edge. Our team is happy to help — call us before ordering if unsure.
