GRP fibreglass roofing in Pontefract

We lay GRP fibreglass roofs in Pontefract 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 Pontefract?

GRP is a good fit in Pontefract 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.

Pontefract's flat roofs are mostly on newer estates where the first extension roofs are now being replaced, with plenty on shops with flat-roofed rear stores below flats too. England averages roughly 870 mm of rain a year; the Pennine side of Yorkshire is wetter and windier than the east, so we specify for the site rather than the county.

How much does a GRP fibreglass roof cost in Pontefract?

At Yorkshire and the Humber guide rates, a 20 m² extension roof in GRP with a new deck and insulation comes to £2,850–£5,100 including VAT. The fixed price comes after a free survey for new and replacement roofs.

Is GRP better than EPDM, felt or a liquid roof?

GRP is the better choice when you want a rigid, walkable finish, a neat look on a visible roof, or crisp moulded details on a complicated shape. It is not automatically better on a plain garage that nobody steps on.

Strengths: hard surface that takes occasional foot traffic; jointless finish with no laps; trims, kerbs and upstands moulded as part of the roof; choice of topcoat colours; small repairs can be laminated in.

Weaknesses: sensitive to weather while laying; rigid, so it can crack where the structure moves; usually needs a new deck; styrene smell during application; skill-dependent, so workmanship matters more than with sheet systems.

For a simple roof, EPDM rubber is often quicker to lay and more forgiving of movement. Torch-on felt is usually cheaper per square metre. A liquid-applied roof can go over a sound existing surface, larger commercial roofs tend to suit single-ply, and older buildings may already have mastic asphalt worth keeping. The EPDM vs GRP vs felt guide compares the three most common choices.

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
  • Resin and glass-mat laminate with taped and reinforced joints

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 Pontefract?

£2,850–£5,100 for a 20 m² extension roof in GRP with a new deck and insulation, at Yorkshire and the Humber guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.

How long before a new GRP roof is fully cured?

The topcoat is usually touch-dry within hours in reasonable weather, but full cure takes longer in cold conditions. We advise keeping off the roof until the team confirms it is ready.

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.
