Professional GRP Roofing Across Reading and the Surrounding Areas

A GRP roof is formed directly on the roof deck using fibreglass reinforcement and resin, followed by a protective topcoat.

Correct preparation, dry installation conditions and careful detailing are essential. We assess the roof structure, decking, drainage and adjoining areas before recommending whether GRP is the right system for the property.

The Benefits of GRP Fibreglass Roofing

GRP fibreglass roofing creates a strong, continuous surface across the roof, without the regular overlaps found in some traditional flat roofing materials. This can provide a clean and weather-resistant finish when the system is installed correctly onto a suitable roof deck.

The material can be formed neatly around roof edges, corners, outlets, rooflights and upstands. Specially designed trims help create a tidy perimeter and make GRP particularly useful for many extensions, garages, dormers, porches and other domestic flat roof areas.

GRP is not automatically the right choice for every flat roof. The size of the roof, potential movement, drainage, condition of the deck and surrounding details all need to be considered before installation. We will explain whether GRP is suitable for your property and discuss alternative flat roofing options where appropriate.

When to Consider GRP Fibreglass Roofing

  • New Flat Roof Installations

  • Replacing a Worn Flat Roof

    A GRP system may be suitable where an older felt or flat roof covering needs complete replacement.
  • Repeated Leaks and Failed Repairs

    Where a roof has been repaired several times but continues to leak, replacing the complete covering may provide a more reliable solution.
  • Dormers, Porches and Bay Roofs

    GRP can be used on smaller flat roof areas where neat edges and detailed finishes are important.
  • Roofs with Complex Details

    The liquid-applied construction of GRP can make it suitable for some roofs with corners, upstands and shaped details..
  • Damaged or Rotten Roof Decking

    The existing deck must be sound and suitable. Any damaged timber should be replaced before the GRP system is installed.

The existing construction needs to be assessed first. Removing the old covering is often necessary so the deck can be inspected and prepared correctly.
