Customers across the north east are feeling the benefits of our top-class GRP roofs. GRP stands for 'Glassfibre Reinforced Plastics' and is also known as 'Fibreglass' and 'composite plastics'. Our GRP roofs are durable, long-lasting and offer exceptional protection from the elements. They can make your home a better, more comfortable place to live whilst adding to its value and helping you cut down your energy bills dramatically. 

Our GRP roofs are a remarkable alternative to regular felt roofs. They have a life expectancy of more than 45 years and can help you forget about any problems you might have experienced with felt flat roofs. As there are no seams or joints, water is not given a chance to penetrate, which means that you won't have to worry about leaks.

We can cater for you if you're looking for durable GRP flat roofs in Darlington, Teeside, Tyneside or Durham.
