How was their new roof constructed/raised?
Is the concrete just holding tiles over yours?
Or have they removed tiles from your ‘side’?
Or is the concrete providing a weather seal?
Where did the membrane underneath end?
Both properties are quite old…probably early Victorian or a smidge earlier. They have pantiles which replaced earlier thatch – this must have been done a long, long time ago.
The neighbours stripped their roof off, battened over the existing structure and raised the roof line by 4 inches or so. New pantiles were used so they look quite different…though that isn’t the end of the world. Tey will mellow in the next hundred years or so :o)
Their tiles have been concreted over mine, probably covering 2/3 of the tile.
It isn’t a weather seal, bits of it started falling out on day one and there is a large void (that they know about) where some of it has dropped away. Other parts are cracking significantly.
No idea where the membrane ends. I have to assume there is some overlap.
The thing is, if I have to work on my roof, I will have to disturb their tiles, and my tiles may even break. They are very old, triple roll, pantiles. You can’t replace them, I tried several years ago when I was trying to replace a couple of broken ones.
The lead flashing idea was agreed because it would allow either of us to undertake running repairs without anything else being damaged.
ATEOTD, they had no right to go ahead and do what they did. They obv thought they could do it and get away with it.
