Posted by Mike Poulton, on Fri 10 May 2013 03:30pm

I have an L Shaped Flat Roof in Fibre Glass that will soon need replacement preferably in Firestone Rubber the size is c30 square metres. Possibly will need additional insulation. Do I need Part L1 B planning approval and who can do this job

Hi Mike, Part L 1b requires the roof to be completed to current building regs ie 125mm warm roof insulation (Uvalue of .015 wmk/3). A member of the NFRC/ Competent roofer scheme can self certify for this. However building control can certify for a nominal sum. Take into consideration the fact that your fascia's will need to be replaced due to the additional roof height. Rgds Mick at Approved Rubber Roofing Contractors Ltd
