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.

GRP Fibreglass Roofing FAQs
What does GRP roofing mean?

GRP stands for glass-reinforced plastic. It is commonly known as fibreglass roofing and is formed using fibreglass reinforcement and resin.
Is GRP suitable for domestic flat roofs?

Yes. It can be suitable for extensions, garages, dormers, porches and other domestic flat roof areas.
Does GRP roofing have visible seams?

The main roof surface is formed as a continuous covering, although trims and detailed areas form part of the complete system.
Can GRP be installed over an old flat roof?/h3>

The existing construction needs to be assessed first. Removing the old covering is often necessary so the deck can be inspected and prepared correctly.
Can a GRP roof be repaired?

Some localised damage may be repairable. We would inspect the roof before advising whether repair or replacement is appropriate.
Can you replace damaged roof decking?

Yes. Any rotten, damaged or unsuitable decking can be replaced before the GRP system is installed.
What is the difference between GRP and EPDM?

GRP is a rigid fibreglass and resin system formed on the roof deck. EPDM is a flexible rubber membrane. The best option depends on the roof’s construction, size, movement and detailing.
Do you cover areas outside Reading?

Yes. We cover Reading and surrounding areas across Berkshire, Hampshire, Buckinghamshire and Surrey.
