EPDM (ethylene propylene diene monomer) is a synthetic rubber membrane widely used on flat and low-pitched roofs because it forms a single, seamless waterproof layer rather than overlapping shingles or felt strips. Fewer joints means fewer places for leaks to start, and its high elasticity lets it expand and contract with temperature changes without cracking.

The kit includes the EPDM membrane precision-cut to your chosen dimensions, water-based deck adhesive, contact adhesive for seams and detail work, black powder-coated aluminium edge trims, all necessary fixings, and step-by-step installation guidance. For most standard garden room roofs, no additional materials are required.

Measure the full roof deck, including any overhang you want the membrane to cover, then select the closest size at or above your measurements from the 2.1m × 2m up to 5m × 7.7m range. It is generally better to size up slightly than to risk the membrane falling short of the edges.

Many customers install EPDM kits themselves using the included instructions, and the fully adhered, single-membrane design is more forgiving than traditional felt or shingle systems. Larger roofs, complex detailing around upstands or pipes, or a lack of confidence with adhesives are good reasons to hire a professional installer instead.

The water-based deck adhesive bonds the main membrane to the roof substrate (plywood, OSB, etc.), while the solvent-based contact adhesive is used for seams, upstands, and detail areas where a faster, stronger initial grip is needed.

With correct installation, the expected lifespan is 50+ years, thanks to the membrane's resistance to UV exposure, temperature extremes (rated -40°C to +120°C), and general weathering.

Both. The powder-coated aluminium trims protect the membrane's edges from wind lift and physical damage while giving the roofline a clean, architectural finish that suits modern garden room designs.

Yes. When correctly fitted, the fully adhered EPDM system is rated 100% waterproof. Performance depends on proper substrate preparation and following the adhesive and seam guidance included in the kit.

This kit is designed for flat roofs and low-pitched roofs. If your structure has a steeper pitch, contact our team before ordering, as a different system may be more appropriate.

Very little. Periodic visual inspection is recommended, checking for debris buildup, secure trim fixings, and no standing water pooling in one area, but there is no recoating or resealing required as with some other roofing materials.

No. EPDM is specifically engineered for exceptional UV stability, so it resists the fading and material breakdown that affects many other roofing membranes under prolonged sun exposure.

The membrane can be trimmed and adhered around most standard detailing using the contact adhesive, but unusual geometries may need extra flashing or trim pieces beyond the standard kit contents. Contact our support team before ordering if your roof has non-standard features.
