The Professionals ChoiceFor GRP Roofing


The last flat roof you'll ever need...

Fibrelast is a GRP (fibreglass) roofing system that has been specifically formulated for any new build timber roof application. Fibrelast cures to a highly durable and extremely hardwearing finish and can withstand regular foot traffic with no need for additional protection. The product is available in a wide range of colours and is protected for up to 25 years by our basecare guarantee system.

Fire Retardant

The specially formulated Fibrelast roofing system as with all Allbase roof coatings is cold applied removing the fire risks associated with traditional roofing systems that rely on exposed flames. Fibrelast is also Fire retardant to BS 476 Part 3 Ext. F.A.A. and complies with all current UK building regulations when applied in accordance with application guidelines.

Flexible System

Fibrelast has been engineered with FibreFlex technology, to increase the flexibility of the resin system without the need for any additional additives which often affects the natural rheology of the resin system. Additional flexibility will help the system deal with any thermal expansion and contraction as the roofing surface heats up and cools down throughout the day.

UV Resistant

The Fibrelast system has built-in inhibitors that withstand ultraviolet and solar degradation, which provides protection and maintains the high quality finish.

Seamless Finish

The Fibrelast GRP roofing system cures with no joints or seams to create a durable, long-lasting surface that's 100% waterproof.

Quality guaranteed as standard

The Fibrelast GRP roofing system has been engineered to endure decades of foul weather, hot temperatures and foot traffic. Whether you’re looking to purchase materials for a DIY project or wanting a professional installation by an approved contractor, our 25-year Basecare warranty ensures your new roof is well covered.


Give your roof a splash of colour

To naturally blend in with the surroundings the Fibrelast finishing system comes in six colours as standard and can even be colour-matched from a specific sample using our Colourcoat matching service. Surface finishes also include a number of anti-slip options and a range of green roofing solutions are also available.
