Traditional bitumen coatings have been in use for over two thousand years with varying degrees of success. It has always been widely accepted these roofs would require regular replacement as each layer of the roof breaks down and becomes ineffective. Alternatives were the use of expensive metal coatings such as copper or lead, or even the more expensive option of installing a pitched roof over the existing flat roof.
GRP is a cost-effective, dependable solution to these problems, which is why its unrivalled performance protects millions of square metres of roofs throughout the UK. Several pieces of research have found GRP buildings 25-30 years old to be structurally sound.* These structures predate the advancements in formulating high performance roofing resins which have occurred in the last 10-15 years. Our GRP roofing product can be expected to last much longer.
