GRP Fibreglass Roofing in Borehamwood

Hard-Wearing GRP Fibreglass Roofing in Borehamwood

A garage or extension roof in GRP fibreglass has no joints for water to work into, because the whole surface cures as one piece. TNR Roofing Services lays fibreglass roofs in Borehamwood and finishes the edges with pre-formed GRP trims, so the roof looks tidy from the ground as well as staying watertight.

From Hemel Hempstead we travel to Borehamwood and the rest of WD6 to lay GRP fibreglass roofs. At the free survey we check the deck, look at the drainage and measure the edges, since a hard fibreglass skin can crack if the boards beneath it move. If the deck isn't firm, we tell you and include new boards in the quote.

What's included

Our GRP Fibreglass Roofing Services in Borehamwood

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

Pricing a GRP Roof in Borehamwood

The cost of a fibreglass roof in Borehamwood comes down to the following, all assessed during your survey:

  • The size of the roof or balcony and how many corners, upstands and edges need forming
  • 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

Our GRP Roofing Steps in Borehamwood

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

Is GRP a good choice for a garage roof?

Yes. It suits garage roofs well, as it cures into one rigid layer with no seams, and pre-formed edge trims give a neat finish along the front and sides.

Why does the deck matter so much with fibreglass?

Cured GRP is a hard skin. If the boards underneath flex, the laminate can crack. That is why we check the deck at the survey and replace it before laying where it is soft or moving.

Do you lay GRP on commercial roofs in WD6?

We do. Our fibreglass work covers commercial flat roofs as well as homes, and we plan the timing with you around the weather and your premises.

Who should I ask about a dormer in a conservation area?

Hertsmere Borough Council. Re-covering a dormer roof is usually maintenance, but if your property is listed or in a conservation area, it is worth checking before any change to how the dormer looks.
