Hi I have just had an extension put onto my house and there are three valley gutters. There is no batons at each side of the guttering and you can fit your whole arm underneath the tiles. The tile batons are sticking out onto the gutter and the tiles are not cut straight. There is no stopper in for water going through under the roof tiles. there is also no overhang on the bottom of the valley gutter so means water may go into the facia??? He said this is finnished ? Can someone please help and let me know should u be able to fit your arm under the tiles? is this done prope
