What Is a GRP Flat Roof And Where Is It Used?

GRP is traditionally “wet” laid, this process involves applying liquid resin to an 18mm tongue and groove decking board, before manually adding glass reinforcement.

A Glass Reinforced Plastic roof is one of the most reliable ways to weatherproof your flat roof and is often cheaper to install and lower maintenance than EDPM counterparts. GRP Roofing is also much easier to install than a EDPM alternative, meaning you can get back to normality in no time.

GRP roofing is now widely regarded as the most cost effective, practical roofing methods on the market.

Benefits of a GRP Flat Roof

  • Safer To Install
    A GRP installation does not require the use of heavy machinery and in the case of our Synoseal system it does not require heat.
  • Strong & Durable
    If installed using our tried and tested methods GRP roofing systems can last a minimum of 30 years, an added 10 years + of life on top of the current industry standard.
  • Customisable
    A variety of roofing trims are available to suit the shape and style of your property.
  • Waterproof
    Due to the fact GRP roofing systems have no seams they are 100% water and weather resistant.
  • Easy to maintain
    Simply brush or hose your GRP roofing system to keep it clean.

GRP Roofing Systems Vs Traditional Felt Roofing

GRP roofing systems have completely changed the roofing industry, in our opinion for the better. Traditionally flat roofing was applied using an old fashioned felt roofing system. While some felt roofs were hard wearing and attractive on the whole they only had an average lifespan of around 5 years compared to the minimum of 30 years which can be achieved using Britelite’s flat roofing system.

For around 80 years felt roofing has been sealed using bitumen however due to its adhesive properties and its extreme sensitivity to heat it could be unsuitable for installation on certain homes. Bitumen also required large amounts of heat to be used during installation. Sometimes this process resulted in the need to use both heavy and expensive machinery.

With a GRP roofing system like Synoseal no heat is necessary, meaning it is not only quick and simple to install, but also suitable for a wider range of homes, meaning we can provide high quality roofing solutions to a variety of properties which until now, did not have a viable roofing system.


We feel that it speaks for itself that more and more customers are choosing to opt for great value GRP roofing solutions instead of a more traditional felted system.

If you are looking for a new GRP Flat Roof to replace your current roof, you are in safe hands with Britelite’s Flat Roof system.
