GRP fibreglass roofing in Great Yarmouth

We lay GRP fibreglass roofs in Great Yarmouth on dormers, extensions, garages and small commercial buildings. A surveyor visits first, free of charge, to check the joists, measure up and see whether the roof suits fibreglass. You then get a fixed written price, and the work is done by vetted roofing teams working under S&K.

Why choose GRP fibreglass roofing in Great Yarmouth?

Some Great Yarmouth homeowners pick GRP for appearance alone. The topcoat comes in several colours, the trims are moulded to match, and the finished roof looks tidy from upstairs windows. With good laying conditions and a sound deck, a GRP roof typically lasts 20 years or more.

In and around Great Yarmouth, flat roofs are typically found on 1930s semis with flat-roofed garages and kitchen extensions, and on terraced streets with flat-roofed rear kitchens and bathrooms. The East of England is the driest part of Britain, with parts of the Anglian region around 630 mm a year, so summer heat and UV, not rainfall, do most of the ageing on a felt roof.

For Great Yarmouth we use East of England rates: £3,150–£5,650 is the guide for a 20 m² extension roof in GRP with a new deck and insulation, VAT included. The fixed price comes after a free survey for new and replacement roofs.

How long does a GRP roof last, and is it guaranteed?

A properly laid GRP roof typically lasts 20 to 40 years. The range is wide because so much depends on the laminate being fully wetted out, the deck staying dry and stable, and the topcoat being renewed if it wears.

When GRP fails early, the cause is usually one of these:

  • resin laid in damp or cold conditions that never fully cured;
  • cracks at board joints or trims where movement was not allowed for;
  • a deck that was wet, soft or poorly fixed before laminating;
  • a thin or patchy topcoat that has weathered through.

On guarantees, manufacturer material guarantees are available on many specified GRP systems, and some need a registered build-up or an approved installer. Where registration is possible, we do it for you. Every re-roof also comes with our written workmanship guarantee, with the length set out in your quote, and you can ask about insurance-backed options. Read more in our guarantees guide.

What's included?

  • Removal of the old covering and disposal of waste
  • Warm-roof insulation and vapour control layer where the room below is heated
  • New OSB3 or plywood deck, fixed at close centres
  • Moulded GRP trims, kerbs and upstands

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 Great Yarmouth?

£3,150–£5,650 for a 20 m² extension roof in GRP with a new deck and insulation, at East of England guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.

What colours does a GRP roof come in?

Topcoats are typically available in greys, greens, black and some other shades. Lighter colours absorb less heat, and an anti-slip finish can be added where people will walk on the roof.

Does GRP smell when it is being laid?

Yes, the resin gives off a strong styrene smell while it cures. It usually fades within a day or so, and we advise keeping nearby windows closed while the team works.
