Hi, my parents have had the some problem with their george wimpy home... this is the second year the gutters have all fallen off. This year it took the facia's with it and so one of the bedrooms took in water. Their's are falling off because they are not secured through the facias to a hard surface at the back. They've said the same thing that it's our responsibility. I would agree with Tony, and we are doing the same. let me know how you get on.
I have no luck with new builds, Builders hate me
