What Is a GRP Fibreglass Roof?

A GRP fibreglass roof is a rigid waterproofing system formed by combining polyester resin with glass-fibre reinforcement over a compatible deck.

The laminated surface is finished with a protective topcoat. Roof edges, wall junctions, outlets and penetrations use system-compatible trims or formed details.

Typical GRP Flat Roof Build-Up

  • A sound, dry and correctly prepared roof deck
  • Compatible edge trims and junction details
  • Resin reinforced with fibreglass mat
  • A specified protective topcoat

GRP vs Felt vs Single-Ply Roofing: Which Is Best?

The best flat-roof system depends on the roof size, shape, use, deck, insulation, drainage, exposure and required finish - not one material being universally better.

 GRP Fibreglass Roofing

GRP creates a rigid laminated covering and is often considered for domestic extensions, garages, dormers and other small-to-medium flat roofs.

 Reinforced Bituminous Felt Roofing

Modern felt uses specified membrane layers with sealed laps. Installation may be torch-applied, self-adhesive or otherwise applied according to the chosen system.

 Single-Ply Membrane Roofing

Single ply uses flexible sheets with welded seams and system-specific attachment, making it suitable for many domestic and commercial specifications.

 A Specification Based on the Roof

We compare the roof build-up and details before recommending a material, helping avoid a system being chosen on appearance or headline price alone.

Does Your GRP Roof Need Repair or Replacement?

A local repair may suit an isolated defect, while widespread deterioration, wet insulation or repeated leaks can make replacement more appropriate.

Signs a Repair May Be Possible

- One identifiable split, seam or damaged detail
- The surrounding covering remains serviceable
- The deck and insulation are sound and dry

Signs Replacement May Be Needed

- Recurring leaks or several failed areas
- Extensive cracking, blistering or delamination
- Defective falls, deck or concealed roof build-up

How Much Does GRP Roofing in Surrey Cost?

Cost depends on the roof size, access, existing build-up, deck condition, insulation, drainage and number of edge or penetration details.

What Is Included in a Flat-Roof Quotation?

A flat-roof quotation should define the access, preparation, roof build-up, waterproofing system and finishing details included in the proposed work.

- Safe access and removal of the existing covering
- Deck, insulation or vapour-control work where required
- The selected waterproofing system and compatible components
- Outlets, upstands, trims, rooflights and penetrations
- Waste removal and final checks

Request a Roof-Specific Quotation

Book a consultation so the proposed work can be based on the actual roof rather than a generic square-metre figure.

Frequently Asked Questions About GRP Roofing in Surrey

Find concise answers about fibreglass roofs, felt, single ply, overlays, maintenance and installation conditions.

What is the difference between felt, GRP and single ply roofing?

Felt roofing uses bitumen layers, GRP is a seamless fibreglass system, and single ply is a durable synthetic membrane. Each offers strong waterproof protection for flat roofs.


What are the benefits of single ply roofing systems?

Single ply roofing delivers flexibility, durability, UV resistance, and a clean finish. It's quick to install and ideal for both residential and commercial flat roofs in Surrey.


What are the signs a felt roof needs replacing?

Signs include water leaks, cracks or blisters in the surface, sagging areas, or persistent moss growth. Early replacement prevents further damage.


Where are single ply membranes most effective?

Single ply membranes are most effective on flat or low-pitch roofs, including extensions, garages, and commercial properties, where seamless waterproofing is crucial.


Where can damaged roofing membranes cause water ingress?

Damaged membranes can allow water to enter at seams, cracks, or blistered areas, leading to interior leaks, damp, and structural decay.


Why does felt roofing deteriorate over time?

Felt roofing can deteriorate from UV exposure, weathering, and temperature changes, which may lead to cracks, splits, and loss of waterproofing.


Why should leaking flat roofs be repaired quickly?

Leaking flat roofs risk serious water damage, mould, and timber rot. Fast repairs protect your property and save money on extensive fixes.


How much does fibreglass roofing cost in Surrey?

Fibreglass (GRP) roof costs depend on roof size and complexity. Bookham Roofing offers free quotations for fibreglass roofs in Surrey.


How long does a fibreglass roof installation take?

Most fibreglass roof installations in Surrey take 1-3 days, depending on the roof size and preparation needed. Bookham Roofing ensures a prompt, tidy service.
