What is GRP?

What is GRP?

GRP refers to glass fibres that have been woven into a matt and kept tightly together by levels of polyester plastic resign. This results in a strong but lightweight product that is perfect for both new and existing roofs.

GRP has been used for many years; in fact, its use can be traced back to 1938. At Findley Roofing & Building, we are fully approved and the local leaders when installing GRP roofing in the North East.

What does GRP stand for?

Glass reinforced plastic – simple but effective.

Glass reinforced plastic is a proven winner when it comes to the application of a new roof.

Useful properties of GRP for roofing

  • Lightweight but very strong
  • Weather resistant even in the most extreme storms
  • Available in many different shapes and sizes
  • Requires zero maintenance
  • Meets all British standard requirements
  • Can be used to build a balcony if you already have a flat roof

Pleasant, hard working and professional

We have just had new facias and gutters fitted and are extremely pleased with the result. Excellent service from start to finish and the 3 man team who carried out the work were very pleasant,… “Pleasant, hard working and professional”

I am delighted with the work I have had done. I had a new kitchen roof and my chimney stack done, very satisfied with all the work done!

Wouldn’t hesitate to recommend

They came at short notice to repair storm damage to our flat roof and parapet wall, and provided a much better service than a few other companies that only wanted to do the roof work… “Wouldn’t hesitate to recommend”
