The First Flexible GRP Roofing System with Full Overlay Capabilities

There is simply no other roofing system capable of delivering a total waterproofing solution across such a wide range of flat roof repair and flat roof coating applications. Similar to fibreglass systems, Flexitec 2020 uses a powder hardener for rapid curing and is reinforced with fibreglass CSM for extra strength and crack-resistance. The finished membrane is also extremely tough, impact resistant and can easily accommodate foot traffic. However due to its unique flexible technology, Flexitec 2020 is able to coat all common roof surfaces such as felt, concrete, asphalt, GRP and timber – meaning roofs can be overlaid without the need for strip and replace works. No matter the size, shape or complexity of the roof, Flexitec 2020 provides a seamless, tough and flexible membrane to any roof or balcony area. This next generation roofing system is available to buy from a wide range of stockists across the UK and Ireland.

Flexitec 2020 Application Video – Felt Overlay

This video shows an application of the Flexitec 2020 System to an existing aged felt roof. Flexitec 2020 is ideal for the refurbishment of roofs where, unlike traditional GRP, there is no need to strip and re-deck the roof – saving you time and money.

What makes Flexitec 2020 different?

  • Similar to GRP fibreglass, Flexitec 2020 is genuinely rapid-curing (30 – 60mins walk-over time) with an extra-tough finish. Similar to liquid overlay systems it’s flexible and can coat a range of roof surfaces.
  • Can be applied to almost any roof surfaces including felt, asphalt, concrete, GRP, PVC single-ply, metal details and approved insulation boards
  • Single resin system that can be repaired / overcoated without grinding down
  • Fire tested to BS 476-3 Rating: F.AA and EN 13501-5(4) Rating: BROOF(t4) – the highest rating a flat roof system can achieve and allowing for unrestricted use under UK regs.

  • Applied as a one coat (10 year repair system) or two coat (20 year roofing system) system
  • Highly flexible and suitable for any size or shape roof without the need for expansion joints
  • Extremely rapid installation with walk-on times of 30-60 minutes
