Design, calculate and order a complete EPDM rubber roofing system with the ClassicBond EPDM Roof Kit Builder & Calculator. This easy-to-use online EPDM roof calculator allows you to enter your roof dimensions and instantly generate a bespoke flat roof kit tailored to your project requirements.

Whether you're replacing an existing felt roof or installing a new flat roof on a garage, extension, garden room, office, shed or outbuilding, our EPDM roofing calculator helps you determine exactly what materials you need. The system automatically calculates the correct EPDM membrane size and recommends the appropriate adhesives, trims, outlets and accessories required to complete your installation.

Unlike standard roofing kits supplied in fixed sizes, the ClassicBond EPDM Kit Builder creates a made-to-measure roofing package based on your exact roof dimensions. This helps minimise waste, avoid costly ordering mistakes and ensures you receive the right materials for a professional, long-lasting flat roof installation.

ClassicBond EPDM rubber roofing is one of the most popular flat roofing systems in the UK, offering exceptional durability, flexibility and weather resistance. With an expected lifespan of over 50 years, EPDM membranes provide a seamless waterproof finish that can withstand UV exposure, heavy rainfall, frost and extreme temperature changes.

Perfect for both trade professionals and DIY customers, the ClassicBond Roof Kit Builder removes the complexity from planning a flat roofing project. Simply enter your measurements, customise your roof layout and receive an instant price for a complete EPDM roofing kit.

Please note: The materials and membrane sizes generated by the ClassicBond EPDM Roof Kit Builder are based on the dimensions entered by the customer. It is the customer's responsibility to ensure all measurements are accurate before placing an order. EPDM membranes are cut to size specifically for each project and are therefore non-returnable once ordered.
