Reinforced bitumen membranes (RBM) remain the dominant waterproofing system in the UK, accounting for more than 50 per cent of the market by installed area. Within a sector valued at approximately £670 million annually, bitumen continues to play a vital role across both new build and refurbishment projects.
The Bitumen Flat Roofing Association (BFRA) has opened membership for 2026–2027, inviting organisations from across the reinforced bitumen membrane (RBM) sector to get involved and help shape the future of flat roofing.
When the Bitumen Flat Roofing Association (BFRA) launched in early 2025, it was in response to a clear and longstanding gap in the industry. Despite the dominance of bitumen, which represents approximately 50 per cent of the UK flat roofing market, there was no single dedicated body championing reinforced bitumen membranes (RBM).
