Leaking Dormer Roof in Solihull — A GRP Rescue Job
When a homeowner on Beechwood Park Road, Solihull, called Radian Roofing, their dormer flat roof had been leaking for months. A previous patch repair had bought some time, but had done nothing to fix the underlying problem. Water had been silently tracking beneath the failed GRP surface and saturating the OSB decking below, rotting the structure from the inside out.
This is one of the most common and costly problems we see on flat roofs across Solihull and Birmingham — a GRP roof installed incorrectly by someone without the right training, failing quietly until the damage becomes serious.
By the time Radian arrived on site, the roof needed far more than a repair. It needed a full rescue.
Worried your flat roof is failing? Don't wait.
What Went Wrong — And Why
A general builder had installed the original GRP fibreglass roof on this Solihull dormer — not a certified GRP specialist. The consequences were predictable:
✓ Wrong resin profiles used throughout the installation
✓ Resin applied too heavily and catalysed too quickly — preventing proper adhesion
✓ GRP laminate had not bonded correctly to the OSB deck beneath
✓ No expansion joints installed anywhere on the 40m² roof
✓ Cracking and delamination were inevitable from day one
✓ Months of water ingress had fully saturated the OSB decking
✓ Sections of the underlying roof timber had begun to rot
This is exactly what happens when someone without specialist training installs GRP fibreglass roofing. GRP is the most durable flat roofing system available in the UK — but only when installed correctly. When it goes wrong, it fails silently until the structural damage is already done.
