Why choose GRP fibreglass roofing in Frome?
Landlords and small businesses in Frome often favour GRP on roofs that contractors need to access for plant, aerials or gutter clearance. The surface resists scuffs better than a soft membrane, and small damage can usually be ground back and re-laminated without disturbing the rest of the roof.
In a town like Frome, flat roofs are commonly found on 1960s and 1970s link-detached houses with flat-roofed garages and porches or newer estates where the first extension roofs are now being replaced. The South West averages roughly 1,260 mm of rain a year and many roofs face wind off the Atlantic, so we specify fixings and edge details for wind uplift as well as drainage.

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?
- Moulded GRP trims, kerbs and upstands
- Resin and glass-mat laminate with taped and reinforced joints
- New OSB3 or plywood deck, fixed at close centres
- Coloured UV-stable topcoat, with anti-slip finish on request
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 Frome?
£3,100–£5,550 for a 20 m² extension roof in GRP with a new deck and insulation, at South West guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.
Can a cracked GRP roof be repaired?
Often, yes. The area is ground back, cleaned and re-laminated with fresh mat and topcoat. If cracks keep returning along joints, the deck or detailing usually needs attention rather than another patch.
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.
