I have a flat roof on an extension that needs re-doing and I wanted to know if the Fibrelast GRP roofing system can be installed as a warm roof?

Yes the Fibrelast GRP roofing system can be laid as a warm , when our approved contractor performs the site survey they will advise the best configuration.  A fibreglass flat roof can be installed with any amount of insulation to suit both the project and current regulations.
