What Is GRP Fibreglass Roofing?

GRP (Glass Reinforced Plastic), also known as fibreglass roofing, is a strong and lightweight laminate formed by combining polyester resin with fine glass fibres. Once cured, it creates a smooth, joint-free surface that is fully waterproof and exceptionally long-lasting.

Benefits of GRP Fibreglass Roofs

1. Seamless and Leak-Free Finish

Unlike traditional felt roofs, GRP is applied as a liquid and cures into a single, jointless membrane. This removes the usual weak spots where leaks develop.

2. Long-Lasting Durability

When installed properly, a GRP roof can last over 25 years without cracking, blistering, or degrading – even under harsh Manchester weather conditions.

3. Lightweight and Strong

Perfect for garages, dormers, extensions, balconies, and more. GRP is strong but doesn’t weigh down the structure.

4. Easy Maintenance and Repairs

GRP roofs require minimal upkeep. If needed, repairs are straightforward, with patching or recoating possible without needing to replace the entire surface.

5. Customisable Finish

Available in a range of colours to complement the look of your home or business premises.

Why GRP Fibreglass is the Best Flat Roof for Manchester Homes

Manchester’s climate makes roofing material choice critical. With over 850mm of rain per year, frequent temperature swings, and persistent damp, you need a flat roofing system that performs reliably over the long term. GRP fibreglass consistently outperforms felt, EPDM, and asphalt in Manchester’s conditions — and that’s why it’s now the most popular choice for home extensions and garages across Greater Manchester.

GRP vs Felt vs EPDM: Which is Best?

GRP vs Felt

  • Lifespan: GRP 25–40 years vs felt’s 10–20 years
  • Seams: GRP is completely seamless; felt has overlapping joints that can separate
  • Maintenance: GRP requires virtually none; felt needs regular inspection and occasional patching
  • Cold weather: GRP remains flexible at low temperatures; older felt systems can become brittle and crack

GRP vs EPDM Rubber

  • Lifespan: Similar — GRP 25–40 years, EPDM 20–30 years
  • Finish: GRP has a cleaner, more attractive finish in multiple colours; EPDM is typically black
  • Rigidity: GRP is rigid and hard — better where foot traffic or load is likely

The GRP Installation Process

  1. Deck preparation — existing roof stripped; damaged timber replaced.
  2. Trimming and edging — GRP trims installed at all edges, upstands, and outlets.
  3. Fibreglass lamination — chopped strand glass fibre matting saturated with polyester resin across the entire surface.
  4. Topcoat application — UV-protective coloured topcoat applied (typically grey, green, or red oxide).
  5. Inspection and guarantee — quality inspection completed and 25-year guarantee issued.
