Before and after on this week’s flat roof.
The old covering on this commercial office block had reached the end of its life — weathered, flaking and starting to let water in. Rather than strip it all off, we overlaid it with a fibreglass-reinforced polyurethane system: a tough resin base, glass matting bedded in for strength, then a seamless, joint-free topcoat over the lot. No felt laps to fail, no seams to lift — a fully bonded roof that flexes with the building and should keep the weather out for decades.
It’s the latest piece of work we’ve carried out on this roof over the last few years. We’ve also rebuilt the box gutter running through the slate roof, re-roofed the slate pitches above it with traditional lead mopstick ridge details, and laid the two other GRP flat roofs that the box gutter discharges into. Old slate, lead and modern liquid systems all working together to keep one awkward roof watertight.

Oh and the drone decided to switch off whilst flying 20m in the air above a patio, so that’s out of action for a little while
