Dexters Build specialises in flat roof installation, replacement, and repair across Bedfordshire. Flat roofs are common on extensions, garages, outbuildings, commercial premises, and some residential properties, and they require specific materials and installation techniques to perform reliably over the long term. Poorly installed or aging flat roofs are one of the most common sources of water ingress in UK buildings.
We install flat roofs using modern, high-performance systems, including GRP (fibreglass), EPDM rubber, and torch-on felt. GRP in particular has become the most popular choice for new flat roof installations due to its exceptional durability, seamless finish, and 25-year-plus lifespan when correctly installed. Unlike traditional felt, a GRP roof does not crack, blister, or allow water to track under seams, making it a significantly more reliable long-term solution.
If your existing flat roof is leaking, blistering, or showing signs of ponding water, it may be approaching the end of its serviceable life. Dexters Build can assess the condition of your current roof and advise on whether a repair is sufficient or whether a full replacement would be the more cost-effective option in the long run.
We cover the whole of Bedfordshire including Bedford, Luton, Dunstable, Leighton Buzzard, Biggleswade, and the surrounding areas. Contact us to arrange a free flat roof survey and quotation.
