Due to what would appear to have been a "Cold Roof Contruction", we had our kitchen ceiling collapse on us over the last week-end. We have now cleared the total scene and are left with the ceramic under brickwork showing and the batons that held the previous ceiling, under a concrete flat roof.
Now it has been suggested that instead of the previous Cold Roof Construction we now go for a warm roof construction, but initially this looks like an expensive situation that we can ill afford.
The flat roof itself is used as a "Patio" and "Summer Dining Area" so there is quite a bit of traffic moving across it.
The surface is starting to peel and we were, prior to the collapse of the ceiling underneath, going to re-seal the roof with Thompsons Roof Seal after cleaning off the dirt & grime etc.
One train of thought that has already been suggested to us was:
To strip the roof completely and not seal it and remove any other covering, which there isn't, and then put on felt. Once that was done with a hot torch then put on a rigid plastic insulation and finally topping this with paving slabs.
This unfortunately would be expensive.
Our train of thought was:
Clean & seal the flat roof with Thompsons Roof Seal.
Either take off & replace or remove completely the existing ceiling support cross members and put in new insulated backed plaster board with adhesive cement.
The only problem I could see with "Our Train of Thought" was the lack of ventilation which would then give any build up of condensation nowhere to go & then the same thing would happen over the cvourse of time as has happend now and the ceiling would collapse again.
Any suggestions & guidance would be sincerely appreciated.
