GRP fibreglass roofing in Newton Abbot

Fibreglass roofing in Newton Abbot: a new timber deck, moulded trims, a resin and glass-mat laminate and a coloured topcoat, built up on the roof to form one hard skin. We strip the old covering, add insulation where the room below is heated, and plan laminating around the weather so the resin cures properly.

Why choose GRP fibreglass roofing in Newton Abbot?

GRP is a good fit in Newton Abbot for roofs with awkward shapes, short runs of upstand and lots of corners, because every detail is laminated in place rather than cut and glued. Where a sheet membrane would need many joins, fibreglass forms one continuous skin across the whole roof.

Newton Abbot's flat roofs are mostly on newer estates where the first extension roofs are now being replaced, with plenty on 1960s and 1970s link-detached houses with flat-roofed garages and porches too. 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.

Why do GRP roofs crack, and can weather affect the installation?

GRP usually cracks where the structure moves and the laminate cannot, typically along board joints, at the junction with trims, or where a roof meets a wall. Weather during laying is the other big factor, because resin cures by chemical reaction and that reaction is sensitive to temperature and moisture.

How we reduce the risk of cracking:

  • boards fixed at close centres so the deck does not flex;
  • joints taped and reinforced with an extra strip of mat;
  • wall junctions finished with a separate trim or flashing, not laminated hard into the masonry;
  • roofs over a certain size divided with movement details where the system calls for them.

And how weather is managed:

  • no laminating in rain, on a damp deck, or when dew or frost is likely before the resin sets;
  • catalyst levels adjusted for the temperature, so resin neither stays tacky on a cold day nor kicks too fast in summer heat;
  • the roof sheeted over if a shower threatens a fresh laminate.

That is why a GRP date can move at short notice. A day's delay costs far less than a laminate that never cures properly.

What's included?

  • Moulded GRP trims, kerbs and upstands
  • Coloured UV-stable topcoat, with anti-slip finish on request
  • Resin and glass-mat laminate with taped and reinforced joints
  • Removal of the old covering and disposal of waste

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 Newton Abbot?

£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.

Can GRP be laid over an existing felt roof?

Generally no. GRP needs a clean, dry, rigid timber deck, so the old felt is usually stripped and the boards replaced before laminating.
