To help understand the condition of the flat roof on top of the Great Cliff building, a roof survey was conducted on 9 April by Langley Waterproofing Systems Ltd, assisted by local contractors, TJ Smith, who provided a cherry-picker. During the survey, it was evident that the rubber based roofing membrane (EPDM Ethylene Propylene Diene Monomer) whilst fixed well, is at the end of its life expectancy, having been fixed almost 20 years ago. It was also evident that there is no insulation boarding and therefore, to comply with current building regulations, this would need to be installed, once the old materials are stripped off.
The main proposal is to strip the decks and replace with a two-layer high performance SBS-modified bitumen system over insulation, vapour barrier and primer, whilst providing a 25 year insurance backed guarantee.
