Portsmouth Flat Roofing for Homes, Businesses & Industrial Units

Commercial & Industrial

From units along Airport Service Road to warehouses near the M275 corridor, many of Portsmouth’s commercial properties face cracked membranes, cut edge corrosion, pooling water and surface deterioration. Our high-performance systems are engineered to refurbish metal, bitumen or concrete substrates while minimising disruption to business operations.

Emergency Services

Allbase supports healthcare and emergency service providers, such as Queen Alexandra Hospital and local ambulance stations, with long-term waterproofing solutions for critical infrastructure. Our systems offer quick cure times and are suitable for phased works on active sites.

Education

Schools and colleges in Portsmouth, including City of Portsmouth College and Mayfield School, frequently encounter roof leaks and outdated roofing materials. We provide tailored systems that address issues like thermal movement, RAAC panels and asbestos, delivering low-odour, quick-install solutions suitable for term-time work.

Residential

Housing in Fratton and new-build developments in Hilsea often require modern waterproofing that integrates with existing architecture. Allbase liquid roofing systems offer fast-curing, odour-free application ideal for homes, garages and extensions with complex detailing.

Heritage & Conservation

From the D-Day Story Museum to community halls and churches, many of Portsmouth’s heritage and cultural buildings require sympathetic roof restoration. Our flexible membranes conform to complex detailing and are approved for use on listed and conservation-grade properties.

Authorities & Housing Associations

Portsmouth Council buildings, like libraries, leisure centres, and civic buildings across often face reduced maintenance budgets and deteriorating flat roofs. Our cold-applied systems are a cost-effective solution to extend the life of public infrastructure and minimise future repair costs.
