What Is A GRP Roof?

GRP stands for Glass Reinforced Polyester. It is a composite material made from a combination of plastic embedded with fine fibres made of glass. The finished product is smooth, attractive, and very strong.

GRP roofs have become very popular in the UK over the last couple of decades, largely because of their durability and longevity. A correctly installed GRP roof is very long-lasting, with a lifespan that is typically over 30 years. There are many advantages to installing a GRP roof including:
Low Maintenance

All you might need to do is occasionally sweep the roof or wash it to remove stubborn marks.

Easy to repair or replace

If your roof fades or develop cracks, it can easily be patched. You can also install another layer of top coat to restore its appearance and condition.

Low risk of leakage

Because there are no joints or seams on the main section of the roof, a leak is extremely unlikely. The only opportunity for water to enter is via poorly installed flashing.

Attractive appearance

The top coat of a GPR roof is much more attractive than other types of roof covering systems.


GRP roofs are one of the most affordable roofing options available, usually coming in at between £70-£100 per square metre (depending on location and condition of roof structure). The long lifespan of GRP roofs makes them excellent value for money.

Simple to install

Experienced tradesmen can install a GRP very quickly, which cuts down on installation costs and makes the roof even more affordable.

Flexible shape

GRP is very useful for dealing with roofs that have an unusual shape that would make other types of roofing difficult to install.

Kath Webber

Really grateful we got John & his colleagues to do some work on our house. We initially got them for rendering but we eventually went with cement fibre cladding installation which John suggested, I am so glad we went with it, they did an amazing job, it looks beautiful, our home looks new. . They are professional and polite, just a delight to work with and they happy to work with you to make sure everyone’s happy and satisfied with the end result. We also needed odd jobs outside done to tie everything nicely together. I’m happy to say I’m a satisfied customer.
