I contacted the roofing company and they responded, below. Am I sunk?
'We have tried to help you out as much as possible on this issue by sending reports, photos and spending a considerable amount of time answering questions at a time when we are most busy.
I do not wish to be obstructive on this issue on the contrary I have tried to be as helpful as possible.
Having read the contents of your correspondence I have just contacted my solicitor who advises me to respond with the following, this work was carried out when B and C Roofing operated as a sole trader.
B and C Roofing when acting as sole traders ceased trading and B and C Roofing Ltd was formed when the company became incorporated.
B and C Roofing Ltd therefore have no legal obligation to instruct Applecliffe to carry out this survey or deal with any issues which arise as a direct result of it as it was not B and C Roofing Ltd who carried out works on this project.
My solicitor also advises me B and C Roofing were acting as subcontractors on this property and were working on the instructions of Simon Richardson who operated as the principle contractor so it should be Mr Richardson you need to contact regarding this issue not us.
We will assist with further documentary evidence if needed but B and C Roofing Ltd will not incur any expense as a direct result of this project.'
