Further development. Our neighbour is saying she is happy with the work, the whole thing gives her anxiety. She wants us to meet with her and the roofer to close the matter, she is now saying she is allowing building regs. I have not heard back from Building Control, I cannot get through to them any more, I keep getting a recorded message "someone from the council tried to call you, we will call you back shortly".
We had asked for a warranty from the roofer, and we received by email a zero-value invoice. There is no text in the body of the email (from a gmail address) and the invoice only contains our details and a reference number. there is no company name, address, contact person or number.
A search on companies house shows there is no company under the name used in the email address.
We are now told that it is a sole trader, not a company and our neighbour has no contract, she has sent us a copy of a leaflet received by post. We asked to see their insurance, nothing is forthcoming.
We called the Citizens Advice Bureau and got through to some national line, as CAB only works 2 days a week for a couple of hours. They advised to claim negligence against the roofers. 1 - we do not have the details of the roofers, a certain Joe using a trade name that cannot be found online. 2 - this was not some damage done by mistake, it was a deliberate decision to ignore our rights and replace our tiles
Our neighbour is saying she will consider the matter closed, she is going on holiday!
