5 years' recorded experience. Domestic flat roofs only. Garages, porches and extensions covered.
GRP fibreglass forms a tough, joint-free surface for domestic flat roofs such as garages, porches and extensions. We begin with a dry and stable deck, then apply resin with glass-fibre reinforcement before finishing the surface with a protective topcoat. Each layer has a job: the deck provides the base, the reinforcement adds strength and the topcoat protects the cured system from the weather. If the substrate is unsound, it needs attention before the new covering goes down.

Edges, outlets and upstands need accurate preparation because they interrupt the main roof surface and handle concentrated water flow. We form the GRP around these details to maintain continuous protection. Installation is arranged for suitable weather so the materials can bond and cure correctly. Once complete, straightforward care helps the roof perform: keep outlets clear and inspect edges or penetrations after severe weather rather than waiting for an indoor drip to announce a problem.
We create seamless coverage across the prepared flat-roof deck.
Resin and glass fibre combine to form a strong, rigid covering.
We shape the system carefully where water leaves or meets an upstand.
The system uses resin reinforced with glass fibre over a prepared deck, followed by a protective topcoat. Once cured, these layers form a rigid covering without the sheet joints found in some other flat-roof materials.
The substrate must be dry, and the resin needs suitable conditions to bond and cure correctly. We consider the weather forecast when arranging installation because applying the materials in unsuitable conditions can affect the finished roof.
Keep outlets free from leaves and debris so water can drain away. It is also sensible to look for damage around edges, upstands or penetrations after severe weather and arrange an inspection if you notice cracking or water entry.
