I have a serious problem with my neighbours. I live in the UK, and there is flat roofing adjoining our two houses. Their flat roof has deteriorated over a number of years, and is allowing water to leak into our house, not theirs. We have written confirmation of this from our insurers, who have said they will repair the damage done to our house, once the neighbours have repaired their roof.

Unfortunately, the neighbours are not cooperating. They claim they had their roof fixed not long ago (which is a lie), and dispute that this is their fault. They have refused to fix their roof. This first happened 2 years ago, and we let the matter drop because of a number of major personal problems at home.

The roof has started leaking again -badly. The damage is extensive, and the neighbours are still refusing to fix it. I have contacted my insurers who say again that the neighbours have to fix their roof first, but they cant enforce anything.
What do I do? Where do I stand legally?

Our neighbours bedroom extends under our roof – we live in old houses that kind of overlap and kind of jigsaw together in places. Due to a leak in the roof, water is getting into her bedroom and she wants us to fix the roof. It is our roof but as part of her room extends underneath it should she be liable to pay any of the repair costs as effectively its our roof thats keeping her dry at night (up until now)?

Anyone with any knowledge of these things please help!
