I had upvc boards fitted over wooden gutter board a few years ago and the rainwater constantly misses parts of the guttering. I have recently had new guttering fitted and the same thing is happening. I thought by having new guttering fitted would not only enhance the appearance of my new windows, which it did, but would solve the problem. The fitters said it was due to the fact that the upvc board was fitted over the wooden board and caused a gap between the roof tiles and the guttering. Can you advice what could be done to rectify, apart from the obvious of taking it all down and replacing the wooden boards. There are asbestos sofits so would be a massive job and cost. I am at my wits end!
