Is a dry fix bonding gutter with central upstand best for joining 2 semi-detached roofs?

Anonymous user 03/03/2024 - 3.27 PM

Hi All, Please can any roofers advise on which type of bonding gutter is best to join the new and the old tiled roofs on neighboring semi-detached properties? Arrived home to find a skip on the front garden and scaffolding up at the semi adjoining my house. The house has recently been sold, I haven't met the neighbours who've not moved in yet. I assume they are going to have their roof re-tiled tomorrow, which will inevitably involve doing something to separate my half. 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 keen to make sure the integrity of my roof isn't damaged, and want to make sure the best solution is used to divide the two. 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 as I assume they're going to turn up any time. Thanks very much for any help.

Are you a tradesperson and able to answer this question?

Hi. The dry bonding gutter that you mentioned is absolutely fine for this type of job. Problems can occur when the new adjoining roof has been installed with higher battens which tend to create a bump, to which, most competent roofers can use various methods to eradicate. It is common practice to encroach onto the adjoining roof, when carrying out this process, as the bonding gutter is installed to make both roof terminations watertight. The roofing contractor should be more than happy to answer any questions you may have. Best of luck. Adrian. AD ROOF SPECIALISTS.

A dry fix bonding gutter is fine between the two roofs as long as it is fitted correctly. A dry fix is better than using mortar as mortar may eventually break down and will need re doing or maintenance Hope this helps Many thanks Mark
