GRP Fibreglass Roofing in Bishop's Stortford

Hard-Wearing GRP Fibreglass Roofing in Bishop's Stortford

GRP, or glass reinforced plastic, is laid wet. We roll resin into a glass fibre mat over a timber deck, and it cures into a single rigid layer with no laps or seams. TNR Roofing Services lays it on extension roofs, balconies and garages in Bishop's Stortford, for homes and commercial properties.

Our GRP installers reach the CM22 and CM23 postcode districts from Hemel Hempstead. Every job starts with a free survey of the deck underneath, because fibreglass is only as sound as the boards it is bonded to, and you get a no-obligation quote once we know what the roof needs.

What's included

Our GRP Fibreglass Roofing Services in Bishop's Stortford

The main parts of the job, each listed in your quote.

  • New GRP flat roofs laminated in one piece, curing into a rigid layer with no laps or seams for water to find.
  • GRP balconies finished with a hard-wearing topcoat, with a textured, slip-resistant option for better grip underfoot.
  • Fibreglass dormer roofs, where moulded corners and trims keep awkward shapes watertight.
  • Extension and garage roofs finished with pre-formed GRP edge and drip trims for a neat, durable edge.
  • Soft or flexing timber decks replaced before laying, so the cured fibreglass sits on a firm base and resists cracking.
  • Cracks in existing GRP repaired by grinding back, re-laminating the damaged section and recoating it.

Pricing

What Shapes the Cost of GRP Roofing in Bishop's Stortford

A GRP quote in Bishop's Stortford is built around these points, each checked at the free survey:

  • Whether the existing timber deck is firm enough to keep or needs replacing with new boards
  • Your topcoat colour and any textured, slip-resistant finish wanted on a balcony
  • The type and length of GRP edge trims, drip trims and gutter details
  • Access to the roof or balcony, including any scaffold needed on upper floors

How it works

How We Lay a GRP Roof in Bishop's Stortford

What happens from your first call to the finished work.

  1. Free Survey and Deck Check

    We look at the deck, the drainage and the roof edges, check the boards for any flex, and note the trims and upstands involved, so the quote reflects the real job.

  2. Quote and Dry-Weather Booking

    You get a no-obligation quote. Once you go ahead, we book the laying for a dry spell, because the resin needs dry conditions to cure as it should.

  3. Decking, Trims and Laminating

    Failing boards are replaced with a firm new deck and the edge trims are fixed. Resin is then rolled through the glass fibre mat until it is fully wetted out, with extra reinforcement at corners and upstands.

  4. Topcoat and Final Review

    When the laminate has cured, the coloured topcoat goes on to seal the surface. Once it has hardened, we clear up, review the completed work with you and confirm everything has been done as agreed.

FAQs

Frequently Asked Questions

What exactly is GRP fibreglass roofing?

It is a roof covering made by rolling resin through a glass fibre mat on site. Once cured, it forms one hard, joint-free layer, which is then sealed with a coloured topcoat.

Is GRP worth the extra cost over felt?

GRP usually costs more than felt, but it gives a hard surface that copes with foot traffic and it does not dry out and crack the way older felt tends to. For a balcony or a roof you walk on, that difference counts.

Do I need planning permission for a GRP balcony?

Re-covering an existing balcony or flat roof is not usually a planning matter, but a new balcony can be. If your Bishop's Stortford home is listed or in a conservation area, check with East Hertfordshire District Council first.

Is the survey free in CM22 and CM23?

Yes. The survey costs nothing, and the quote that follows carries no obligation to go ahead.
