EPDM is the most forgiving flat roofing material there is: it goes down cold, in one piece, with no flame and no specialist tools. If you can measure a roof, sweep it clean and use a paint roller, you can fit this kit. Our free installation manual walks through every stage, and you can email us mid-job.\u003c\/p\u003e\n\u003ch3\u003eWhich size do I need?\u003c\/h3\u003e\n\u003cp\u003eMeasure your roof deck, then add 150mm to each of the four sides and order the kit closest to — but not smaller than — that figure. A 1.8m × 1.2m deck needs a 2.1m × 1.5m kit. If you are between sizes, go up.\u003c\/p\u003e\n\u003ch3\u003eWill the membrane have a join or seam?\u003c\/h3\u003e\n\u003cp\u003eNo. Every kit is supplied as one continuous sheet at the size you order, so there is nothing to tape or overlap and no seam that can fail later.\u003c\/p\u003e\n\u003ch3\u003eWhat exactly is included?\u003c\/h3\u003e\n\u003cp\u003eA 1.0mm EPDM membrane cut to your size, water-based deck adhesive for bonding it down, edge sealing mastic for the perimeter and upstands, and an application roller.\u003c\/p\u003e\n\u003ch3\u003eDo I need edge trims as well?\u003c\/h3\u003e\n\u003cp\u003eNot always. Many shed roofs are finished by dressing the rubber over the edge and sealing it with the mastic supplied. Trims give a crisper finish, protect the edge and are worth adding where the roof drains into a gutter — drip trim on the gutter edge, kerb trim elsewhere, with a moulded corner at every turn.\u003c\/p\u003e\n\u003ch3\u003eHow long does it take to fit?\u003c\/h3\u003e\n\u003cp\u003eA typical shed roof takes an afternoon: around 30 minutes of preparation, 30 minutes letting the sheet relax, an hour to bond it, and an hour on the edges and details. Allow longer for your first roof and do not rush the deck preparation.\u003c\/p\u003e\n\u003ch3\u003eDoes the deck have to be dry, and what weather do I need?\u003c\/h3\u003e\n\u003cp\u003eYes — the deck must be completely dry, and you need a dry day at 5°C or above with no rain forecast until the adhesive has cured. Water-based adhesive will not bond to a damp deck, and trapped moisture is the main cause of blisters under a new roof.\u003c\/p\u003e\n\u003ch3\u003eCan I lay EPDM straight over my old felt?\u003c\/h3\u003e\n\u003cp\u003eSometimes, but stripping is better. Overlaying only works if the old felt is fully stuck down, flat, dry and free of mineral chippings. Stripping back to the deck lets you see the boards, fix the soft ones and start from a sound base — on a shed it is usually an hour of work.\u003c\/p\u003e\n\u003ch3\u003eHow long will it last, and is it guaranteed?\u003c\/h3\u003e\n\u003cp\u003eThe membrane carries a 20-year product guarantee and has a field life expectancy of up to 50 years. Felt on the same shed would typically need replacing two to five times over that period.\u003c\/p\u003e\n\u003ch3\u003eDoes it cope with standing water?\u003c\/h3\u003e\n\u003cp\u003eYes. EPDM is unaffected by ponding water, which is why it suits shed roofs where the fall is often less than ideal. It is still worth building in a fall of 1:80 or better so the roof drains and stays clean.\u003c\/p\u003e\n\u003ch3\u003eDo I need a primer?\u003c\/h3\u003e\n\u003cp\u003eNo. The water-based adhesive supplied bonds directly to sound timber decking — OSB, plywood or planed board. Primer is only needed for specialist details such as bonding to an existing membrane.\u003c\/p\u003e\n\u003ch3\u003eWhich side of the membrane goes up?\u003c\/h3\u003e\n\u003cp\u003eEPDM of this type is the same both sides, so there is no wrong way up. Just make sure the side that touches the deck is clean and free of dust before it goes into the adhesive.\u003c\/p\u003e\n\u003ch3\u003eCan I walk on it once it is fitted?\u003c\/h3\u003e\n\u003cp\u003eYes, for maintenance in soft-soled shoes. It is not intended as a walking surface for regular traffic — if you plan to use the roof, add walkway pads over the membrane rather than walking directly on it. Never walk on it wet or frosty; it becomes very slippery.\u003c\/p\u003e\n\u003ch3\u003eWhat if I get a bubble or a wrinkle?\u003c\/h3\u003e\n\u003cp\u003eWork it out to the nearest edge with the roller or a soft broom while the adhesive is still wet. A small bubble that sets is cosmetic rather than a leak, but a wrinkle that runs to an edge should be lifted and re-bedded before you seal the perimeter.\u003c\/p\u003e\n\u003ch3\u003eWhat fall does the roof need?\u003c\/h3\u003e\n\u003cp\u003eA minimum of 1:80 towards the drainage edge — 25mm of drop for every 2m of run. If your shed roof is dead flat, pack the joists or add firring strips before the rubber goes down.\u003c\/p\u003e\n\u003ch3\u003eCan I put decking or a green roof over it?\u003c\/h3\u003e\n\u003cp\u003eYes, with protection. Walkway pads or a protection layer must go between the membrane and anything laid on top, and nothing sharp should sit directly on the rubber. Ask us before you build anything heavy onto a shed roof.\u003c\/p\u003e\n\u003ch3\u003eHow much maintenance does it need?\u003c\/h3\u003e\n\u003cp\u003eTen minutes a year. Clear leaves and debris off the roof and out of the gutter, and check the edges and any details after big storms. There is nothing to re-coat, treat or paint.\u003c\/p\u003e\n\u003ch3\u003eWhat if I order the wrong size?\u003c\/h3\u003e\n\u003cp\u003eUnused, uncut kits can be returned within 30 days in their original packaging. Once the membrane has been cut it cannot be returned, which is why we would rather size it with you first — send us your dimensions.\u003c\/p\u003e\n\n\u003ch2\u003eGuides that go with this kit\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003ca href=\"\/pages\/how-to-fit-epdm-roof-shed\"\u003eHow to fit an EPDM roof on a shed\u003c\/a\u003e — the full illustrated method\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"\/pages\/how-to-fit-epdm-roof-trims\"\u003eFitting edge trims\u003c\/a\u003e — which trim goes on which edge\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"\/pages\/how-to-waterproof-epdm-roof-corners\"\u003eForming corners\u003c\/a\u003e — folding rather than cutting\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"\/pages\/epdm-maintenance-care\"\u003eMaintenance and care\u003c\/a\u003e — the annual ten minutes\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/pages\/epdm-learning-centre\"\u003eThe full EPDM Learning Centre\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e\n{\"@context\":\"https:\/\/schema.org\",\"@type\":\"FAQPage\",\"mainEntity\":[{\"@type\":\"Question\",\"name\":\"Can a complete beginner fit an EPDM shed roof kit?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Yes.
