Cure-It Fibreglass Roofing (GRP)

R&D Roofing are fully trained Fibreglass GRP Roofing installers.

GRP (Glass Reinforced Plastic) also known as fibreglass. This consists of a mat of glass fibre strands used in conjunction with a flexible resin compound which cures to a tough and durable finish.

GRP has been in use for many years and has been used for marine craft such as boats and yachts. It has also been used for car bodies and is found in aircraft manufacture. It is also recognised by construction authorities and home insurers as a premium flat roofing solution. We believe that our product is the ultimate solution for flat roofing; it will require no maintenance and will look good for years. A GRP roofing system will give you peace of mind for many years to come.

Any questions?

What is fibreglass roofing?

Fibreglass is a fibre reinforced polymer made of a plastic matrix reinforced by fine fibres of glass.

What makes fibreglass ideal for flat roofs?

Fibreglass is a lightweight, extremely strong, and robust material. GRP material is not brittle, and the raw materials are much less expensive. Its bulk strength and weight properties are also very favourable when compared to other waterproofings, and it can be easily formed using moulding processes.

How long will a 'Cure-it' fibreglass roof last?

It’s true to say the longevity of a GRP roof is more to do with the quality and experience of the Contractor than the choice of materials; we believe a GRP roof can outlast any other roof covering.

How easy is it to repair a fibreglass roof in the event of damage?

In case of damage, the GRP can easily be repaired by either cutting out the damaged area and re-applying fibreglass matting and resin.

Can certain materials damage fibreglass roofs?

There are no common materials or substances that will cause damage to GRP. But Acidic cleaners, Paint Stripper and Rust Remover can strip Gel Coats.

Can i walk on a GRP roofing system?

Yes. We recommend using a anti-slip top coat.

Is there a warranty for 'Cure-it' fibreglass roof systems?

Yes, R&D Roofing offers a 20 year warranty and the manufacturer of ‘Cure it Fibreglass’ offers a 20 year material warranty.
