Sweating and mouldy New cold flat roof

Luckily for this house owner, he had spotted the problem and stopped work. Like usual, the problems with the cold flat roof installation was not understanding just how a cold flat roof works and how important the ventilation and the vapour control layer is to form a cold flat roof. The light fittings had been cut through the insulation and were venting into the vented space above. Not only this but large areas of the cold roof vented space was dead meaning that there is no through ventilation. Though ventilation is one of the most critical parts of the construction of a cold roof. Using the foil on solid roof insulation is not a good thing even though the roofing insulation manufacturers sys you can when asked. My video to Flat roof mould above shows how this was tried and how it failed. Generally speaking, we are now seeing bad workmanship in construction in all sectors. The roofing world is starting to wake up to its responsibility for training however they are focusing on roofing only and are not training new roofers in how to install the insinuation to the roof. Insulating a roof is not just the builder's job but also the roofer's job especially if the work is retrofit as there probably won't be a builder on-site and the main contractor will be the roofer. #londonflatroofing #roofsurveyor #coldflatroof Steven Dickinson  London flat roofing  07802300099 @donflatroofing.co.uk
