We have a bathroom and garage extension to our bungalow and, for some time, have been experiencing water leaks through the roof in some situations: heavy rain and wind in the wrong direction.
The roof to the extension is of a single slope ('lean to') type but of very low pitch (I'd say less than 15 degrees). To make matters worse, there is very little overlap of the slates. Both of these factors, I am sure, contribute to the water ingress.
Clearly the roof at present is inadequate and will need to be replaced. Does anyone have any suggestions as to the best remedy, please? One gentleman who visited suggested that the slates be replaced by a rubber compound mounted on timber (plywood?) boards.
