Issue with dampness in neighbouring building

[Constanza]

We are a small women’s centre based in North London. We have been approached by email by the owner of a neighbouring flat to our premises. The email states that there has been an issue with the gutter and down pipe on the roof of our centre which abuts his property which he has rented to a tenant. He claims that a lack of waterproofing has caused a leak, which has come through the walls and caused dampness. We had never been alerted to any issue prior to this email. He went on to say that due to recent rainfall he had to take action to remedy the issues. We can see that a coat of bitumen waterproofing has been applied. The neighbour is asking for a contribution from us towards the cost of these repairs which he lists as:

(a) Approx £600 on waterproofing the roof wall

(b) Approx £1000 for the leakage/damp


We would be grateful for any advice about our liability in this regard. Especially as we were not alerted in good time to the issue so that we could take action and also not consulted about the remedy that was undertook.

Does your centre own or lease your building?
have you checked that your guttering &/or down pipe has a fault which might direct water on to his building?

Even if it has, and if you are responsible for the rainwater goods, I do not see that you should contribute to waterproofing his building.
Yes, you would need to repair the guttering etc (if it is your responsibility) and perhaps contribute to the cost of making good any damage already caused (again only if you are responsible).
He would need to provide evidence that 1) your rainwater goods were the reason for the damage and 2) that he tried to mitigate his losses (ie didn't necessarily take the highest quote) 3) proof of the costs


on another take: small women's centre it wouldn't be called the Louisa Alcott Centre by any chance?

Thank you very much for this response, really helpful. To your last point - we are the West Hampstead Womens Centre.
