    Helpful guides: What's in an EPDM Roof Kit? | EPDM Cost Guide | DIY Installation Guide | Which Thickness?

    Buy complete EPDM rubber roof kits for sheds, garages, extensions, garden rooms, orangeries, porches, and dormers — all with free UK delivery. Every kit includes a pre-cut EPDM membrane, bonding adhesive, primer, and all the trims and fixings needed for a professional-grade, fully waterproof installation. Simply measure your roof, choose your kit, and everything arrives ready to install.

    Our EPDM roofing kits use BBA-certified rubber membrane with a guaranteed 50+ year lifespan — the same material used by professional flat roofing contractors across the UK. Unlike felt or fibreglass (GRP) roofing, EPDM is a single-piece, seamless membrane that won't crack, blister, or degrade in UV light. It performs in temperatures from -45°C to +120°C and requires virtually zero maintenance once installed.

    All kits are available in 1.2mm and 1.5mm thicknesses. The 1.2mm membrane is ideal for sheds, garden rooms, and outbuildings. The 1.5mm heavy-duty membrane is recommended for garages, extensions, and any roof subject to foot traffic or extreme weather. Both options come cut to your exact dimensions — no waste, no guesswork.

    Whether you're a DIY homeowner or a professional roofer, our kits are designed for easy installation. The system bonds directly to timber decking, insulation boards, or existing roof substrates using our high-strength contact adhesive. Full installation guides, video tutorials, and technical support are available with every order. Most sheds and small garage roofs can be completed in a single day.

    Kits available for every roof size and type: shed roof kits from £78, porch kits, dormer kits, gutter lining kits, garden room kits with black metal edge trims, and full orangery systems.
