The garage is a continuation of the bungalows low pitched concrete tiled roof.
We are having damp patches appearing in the plaster after a good downpour. This is only in one section of the plaster-board and seems to be in line with the loft opening in the main building. Thought it might be sagging felt due to the wider space between the joists along that line ? As there is no loft space in the garage roof I thought I might cut a hatch(s) in the plasterboard above the leak with a view to sliding in an additional support for the felt (and also to find out if this is the problem) ???
Many thanks for any advice
