Our Most Popular Solution!

GRP is our most popular flat roof solution. It is superior to felt systems due to its seamless design (meaning no laps, vulnerable to water penetration).

From an aesthetic point of view, GRP looks great. Perfect for overlooked flat roofs. Although the top coat (grey coat) will fade in colour over a period of time, it can be easily re-painted in future years *at additional cost. GRP installations come with a new 18mm OSB ply deck as standard, which also contributes to the clean lines of the flat roof, giving a modern contemporary feel.

User Reviews

“A good family firm. Peter’s son was part of the team that fitted the roof. They all worked extremely hard and I was very pleased with the quality of the work. They even came to finish off some work on a Saturday. The team were informative about work, when asked and very polite and considerate in going about their business. Overall an excellent experience.”

“From original visit and estimate submission to completion of works, Barris Roofing made the entire experience simple and painless. Valuable advice and guidance were freely given, and the work was carried out exactly as promised. The various team members were courteous and respectful at all times, and disruption was kept to a minimum. All of this at an extremely competitive price, and full settlement upon completion of works – no deposit requested. I cannot praise this outfit highly enough. Would recommend Barris Roofing without hesitation.”
