GRP fibreglass roofing in Urmston

We lay GRP fibreglass roofs in Urmston 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 Urmston?

GRP is a good choice in Urmston 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.

Around Urmston, flat roofs are common on low-rise post-war blocks of flats and on bungalows with flat-roofed side extensions and dormers. The North West is one of England's wetter regions, averaging roughly 1,290 mm of rain a year, so falls, outlets and well-detailed upstands matter more than the membrane colour.

How much does a GRP fibreglass roof cost in Urmston?

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?

  • Warm-roof insulation and vapour control layer where the room below is heated
  • Coloured UV-stable topcoat, with anti-slip finish on request
  • Removal of the old covering and disposal of waste
  • New OSB3 or plywood deck, fixed at close centres

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 Urmston?

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

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.

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.
