Flat Roofing

Flat roof costs depend on the roof area, structural condition, chosen material (such as EPDM rubber, GRP fiberglass, or felt), and any required insulation upgrades. Small garage or extension roofs are quite affordable, while large commercial roofs cost more. We always carry out a site survey and provide a clear, itemized written quote.

Common signs include standing/ponding water that doesn’t drain, visible cracks, blisters, pooling under the membrane, or interior damp patches. Minor punctures or loose flashing can often be repaired quickly, but aging membranes across the entire surface usually mean a complete replacement is the best long-term option.

Lifespans vary by material and installation quality. Traditional three-layer felt roofs typically last 15–20 years, while modern single-ply, EPDM rubber, and GRP fiberglass systems can easily last 30 to 50+ years with minimal ongoing maintenance.

Most roofing work, including repairs and replacements, will not require planning permission. However, if your property is in a conservation area, a listed building, or if you are making significant changes to the roof’s shape or height, planning permission may be needed. We can advise if this applies to your home.

Yes. We safely remove spray foam insulation, which is often damaging and can reduce your property’s value. In many cases, spray foam removal does not mean you need a new roof. Once the spray foam insulation is removed, we inspect the condition of the roof and loft space, advise on any repairs, and recommend suitable alternative insulation solutions.
