Flat Roofing Services for Bristol’s Homes, Businesses and Public Buildings

Bristol’s built environment includes a wide mix of residential terraces, industrial estates, shopping centres and heritage buildings. Each roof type brings its own set of challenges. Allbase provides cold-applied liquid roofing systems designed to solve flat roof issues such as leaks, cut edge corrosion, UV breakdown and thermal movement. Whether you’re managing a civic site in Redcliffe or a retail unit in Filton, our systems deliver dependable waterproofing backed by over 30 years of expertise.

Commercial & Industrial

From Avonmouth to St Philips and Hengrove Retail Park, flat roofs on commercial and industrial premises in Bristol often suffer from cracked membranes, water ingress, ageing surfaces and corrosion. Our cold-applied liquid systems offer fast, seamless waterproofing over metal, felt or bitumen, without interrupting operations or requiring full roof removal.

Emergency Services

Southmead Hospital, Bristol Royal Infirmary and fire stations across the city require safe, quick and reliable waterproofing solutions. Our systems are cold-applied, low odour and fast-curing, making them ideal for live healthcare environments and high-dependency buildings with tight schedules and minimal tolerance for disruption.

Education

From the University of Bristol to academies in Southville and St George, many education buildings face issues like asbestos-based felts, RAAC concerns, thermal movement and weathered substrates. Allbase membranes adhere securely to a wide range of surfaces and cure fast — ideal for installations during term breaks or limited-access maintenance windows.

Residential

Homes across Clifton, Easton and Bedminster frequently experience thermal movement, UV degradation and aged waterproofing on garages, dormers or extensions. Our systems are clean, quiet to install and provide long-term protection for domestic and housing association properties alike.

Heritage & Conservation

Bristol’s historic civic buildings and museums, such as those near Queen Square and the Old City, require sensitive roof restoration. Our cold-applied membranes preserve architectural features while delivering modern waterproofing performance with no invasive works.

Authorities & Housing Associations

Bristol City Council buildings and housing stock across areas like Knowle West and Lawrence Weston benefit from Allbase systems that reduce long-term repair needs. Backed by technical support and warranty cover, our solutions deliver dependable performance in both public and social housing schemes.
