We had some roof repairs made about 3 years ago but the mortar around the valley is crumbling and falling out.
Does 3 years sound too soon for this to be happening? It appears that this aspect and the mortar around the verges are not covered in any guarantee.
I am going to repair the work myself, and have been told that a 4 -1 mix using sharp sand and a small amount of PVA added to the water is the way to go. Any suggestions?
