What flat roof work do we do in Formby?
Liquid-applied roofing
Liquid roofing suits a roof in Formby that is full of penetrations, such as soil pipes, vents, aerial brackets and rooflights, because the liquid flows around each one and cures into a single skin. There are no cut pieces or taped corners to work loose over time.
Single-ply membrane roofing
On exposed sites in Formby and elsewhere, mechanically fixed single-ply is specified with a fixing pattern based on wind uplift, with extra fasteners at corners and edges. That makes it a strong option for commercial roofs where wind loads are a concern.
GRP fibreglass roofing
If a flat roof in Formby has already been patched with fibreglass that keeps cracking, a full GRP replacement on a new, properly fixed deck often solves the problem. Cracks usually come from movement in the boards beneath, so renewing the deck and reinforcing the joints deals with the cause.

What flat roofs are typical in and around Formby?
In a town like Formby flat roofs are mostly on terraced streets with flat-roofed rear kitchens and bathrooms and low-rise post-war blocks of flats. Local weather shapes the specification. The North West is one of England's wetter regions, averaging roughly 1,290 mm of rain a year, so falls, outlets and well-detailed upstands matter more than the membrane colour. Approximate 1991–2020 regional averages based on Met Office data.
Who approves flat roof work in Formby?
Where approval is needed it goes to Sefton Council building control, or a registered building control approver. Replacing more than half of a roof over a heated room usually counts as renovating a thermal element, so it is insulated to current standards and notified to building control. How the rules work.
