Popular styles include modern minimalist decks with glass railings, lush urban gardens with planters and lighting, relaxed Scandinavian-inspired chill zones, and entertainer’s rooftops featuring built-in seating and BBQ areas.
Use a floating deck system supported by adjustable pedestals. This approach avoids penetrating the membrane and allows for ventilation and drainage beneath the decking. Add protective pads or walkway mats under pedestals for extra protection.
Two popular DIY-friendly options are EPDM rubber (a flexible, long-lasting membrane) and liquid polyurethane (PU) coatings, which form a seamless finish. Both systems protect your structure and are easy to install with the right prep.
Proper drainage is vital. Without it, water can pool and cause leaks or long-term structural damage. Always ensure your roof has a slight slope and install high-quality drainage outlets that are easy to maintain.

EPDM adhesive is applied to both the underside of the membrane and to the substrate. It should be left to flash off until tacky and can be left on too long. If using a water-based EPDM adhesive – it is applied white and if goes clear, it has been left on too long. Bonding adhesives have a longer flashing time and can be left for
EPDM can be adhered to all types of timber roof substrates and onto OSB or plywood for the best results. It is typically adhered to wood roof decks using a water-based adhesive. It can be adhered to other surfaces such as a tissue-faced insulation board using a contact bonding adhesive.
Coverage rates for EPDM adhesives do vary according to substrate, the type of membrane used and the method of application. On average, a good quality roofing adhesive should typically deliver the following coverage, when following the manufacturer guidelines for application: Water-based roofing adhesive – 3 - 4m2 per litre Bonding/contact adhesive – 3.5 – 4m2 per litre
The tools needed to install EPDM are as follows: Rollers – to apply the adhesive to the deck Soft brush or broom – to ensure 100% adhesion with no air pockets Penny roller and 50mm silicone seam roller – to dress in the details and any seams
