Why choose GRP fibreglass roofing in Stoke-on-Trent?
GRP is a good choice in Stoke-on-Trent when the roof will be seen or used: a dormer visible from the street, an extension overlooked by upstairs windows, or a roof that needs access for cleaning or maintenance. The hard, jointless finish and moulded trims give a neat result that copes with occasional foot traffic.
Stoke-on-Trent's flat roofs are mostly on 1930s semis with flat-roofed garages and kitchen extensions, with plenty on 1960s and 1970s link-detached houses with flat-roofed garages and porches too. England averages roughly 870 mm of rain a year and the West Midlands sits close to that, so falls and outlets are the difference between a roof that drains and one that ponds.

Will a new GRP roof need extra insulation to meet building regulations?
If the roof is over a heated room and you are replacing more than half of it, usually yes. In England, Wales and Northern Ireland that counts as renovating a thermal element, and in Scotland the council's building standards service will say whether a building warrant applies.
GRP pairs well with a warm roof because the new deck boards it needs can sit on top of the insulation. The result is thicker, so we check at survey that there is room under door cills and wall flashings, and that the upstands can finish around 150 mm above the new surface. Where approval is needed we arrange it with building control or building standards.
Unheated, detached garages normally sit outside the thermal rules. See the building regulations page for each nation, or the warm vs cold roof guide for why we avoid cold roofs where we can.
What's included?
- New OSB3 or plywood deck, fixed at close centres
- Coloured UV-stable topcoat, with anti-slip finish on request
- Moulded GRP trims, kerbs and upstands
- Warm-roof insulation and vapour control layer where the room below is heated
Building regulations in England
Replacing more than half of a flat roof over a heated room usually counts as renovating a thermal element, so the roof is insulated to around 0.16 W/m²K where that's technically and economically feasible, and the work is notified to building control: the council or a registered building control approver, unless a registered competent person self-certifies it. A roof on a new extension is built to 0.15 W/m²K. Patch repairs, and most unheated detached garages, don't trigger the upgrade. Structural changes, or a new covering that adds 15% or more to the roof's weight, also need approval. More on the rules.

How much does a GRP fibreglass roof cost in Stoke-on-Trent?
£3,000–£5,400 for a 20 m² extension roof in GRP with a new deck and insulation, at West Midlands guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.
Can you walk on a GRP roof?
Yes, a correctly laid GRP roof takes occasional foot traffic, such as cleaning windows or maintaining plant. For a regular walkway or terrace, an anti-slip topcoat and a suitable specification are needed.
Is GRP suitable for a dormer roof?
Yes, GRP is commonly used on dormers because the trims can be moulded neatly and the finish looks tidy from the ground. Scaffold is normally needed, which we include in the quote.
