Semi-detached roof - which type of bonding gutter is best?

mj73

Hi All,

Please can any roofers advise on which type of bonding gutter is best to join the new and the old roofs on neighboring semi-detached properties?

Arrived home tonight to find a skip on the front garden and scaffolding up at the semi adjoining my house. House has recently been sold, haven't met the neighbours and they've not moved in yet. I assume they are going to have their roof replaced tomorrow, but haven't bothered to contact me.

My roof is fine and has no issues at all. Neither roof has been replaced before, so there is currently no bonding gutter.

Searching online, I understand a bonding gutter will need to be fitted with the new roof. As far as I can tell, the best option seems to be a pre-formed dry fix bonding gutter with a central upstand because, unlike a standard flat bonding gutter, this doesn't require any mortar to be used, which, unless applied carefully, can block the drainage channels under the tiles, and will eventually crack and fail anyway as the mortar weathers and the tiles expand and contract.

Obviously, I'm concerned about potential damage to my roof, or a poor job resulting in water leaking in on my side in the future, so is the best option I should insist on a dry fix gutter with an upstand?

I intend to ask the roofers when they arrive what they're planning to do, so is there anything else I should also be asking / checking on about the the felt / lining / overlap or anything else please?

I'd be really grateful for any responses - especially quick ones as I assume they're going to turn up first thing in the morning!

Thanks very much for any help.

If they plan on using the same type of tiles (or even reusing the originals), no need for a bonding gutter. Have a chat with the roofers before going in guns blazing and making demands.

Thanks FreeBear, my plan is to ask, I just want to make sure I'm asking the right questions.
Given the age of the houses I'm confident they will be replacing the whole roof with new tiles, not replacing with or re-sing the same ones.
