Hi Firstly im no roofer but this week our neighbours have had a new roof fitted and the roofers unknowingly to us have fitted a bonding gutter, they have been on our roof removed some tiles to fit felting and the bonding gutter. Legally how do we stand we had no idea about this it was just when we saw the job on the roof looks awful on old cottages tbh. The guttering is not straight and looks like a few of our tiles are not sitting correctly now! The obviously replaced the neighbouring copping stone and they aren’t even straight! Took the a day and a half to do both sides which amazed me. Thanks for looking/helping.
