The Metrodeck fire-retardant GRP roofing kit achieves BS476 Part 3 FAA – the highest External Fire Exposure Roof Test classification in the UK. Crucially, this rating is achieved without requiring slate granules on the top surface, giving a cleaner, more modern finish than competing systems while still meeting or exceeding all building regulation requirements.

Kits are available in 15 sizes, covering roof areas from 5m² up to 100m² (5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 60, 70, 80, 90 and 100m²). Each kit is precisely calculated to include the right quantities of resin, topcoat, and matting for that area, plus additional material for overlaps and detailing.

Yes — every Metrodeck GRP roofing kit includes the necessary tools. Small toolkits cover 5m²–15m² kits; medium toolkits cover 20m²–45m²; and large toolkits cover 50m² and above. This means you have everything you need in a single order, with no need to source tools separately.

The standard topcoat colour is Dark Admiralty Grey BS18B25. It is UV stable, flexible, chemical and heat resistant, and engineered to resist thermal expansion — meaning it won’t crack as the roof expands and contracts with temperature changes. This colour is compliant with planning guidance for most residential and commercial applications in the UK.

Yes. A 20-year guarantee on materials can be supplied with each Metrodeck GRP roofing kit. This makes it one of the longest material guarantees available on any GRP flat roofing system in the UK, providing excellent long-term value for homeowners and contractors alike.

Yes. While all standard kits use 450gsm chopped strand matting, 600gsm matting is available for applications requiring a heavier, thicker laminate (such as roof terraces). Additional resin will be required for this upgrade. Please call our team on 0800 612 7903 for a customised quote.
