Hi, my roof was retiled over twenty years ago and ridge tiles were used to cover the roof join with my neighbour. My neighbour has now had a new roof (also tiles) and has taken off these ridge tiles. I am guessing they have used a bonding gutter but all I can see is a row of tiles similar to mine along the join (lighter in colour as mine have obviously weathered).
Am I better off with this new way of doing the join? Are there any problems I should be aware of?
I was annoyed this happened without anyone consulting me but I am thinking maybe it is better for me too as I am guessing the mortar bed would have needed redoing at some point in the future. I don’t want to make an issue if it’s actually better for me. Many thanks for any opinions.
Are you a tradesperson and able to answer this question?
They may have just joined the roof tiles up to your roof tiles if they are the same,
A bonding gutter can be used but can cause water ingress into your property if there are any weaknesses in your under felt.
Good luck Alex
Bonding gutters are used quite a lot and only rarely cause an issue (usually because of bad workmanship) they’re not as good/safe/watertight as stitching into the original courses of tiles. Shouldn’t realistically cause any issues and an easy fix if they do, I wouldn’t worry too much

Don’t listen to the fear mongers above, a bonding gutter is a brilliant way of joining to different types of roof tiles it basically acts as a secret gutter. If they had the intelligence to use this method I highly doubt they would have poor workman ship even if let’s say it does leak which it won’t it’s an easy fix to adjust your tiles to suit or neighbors tils or even just replace the bond strip if it damaged or can’t be reused.
The old fashion way of using ridge tiles looks terrible and like you mentioned the mortor will fail in due time in the future the bonding strip will out last any cement mortor as it’s made of fibreglass which has a life expectancy of 50+ years were mortor is so dependent on it being mixed properly and having the correct ratio of sand to cement. Bonding strips which evermore type hide or visible with the big hump or little jump they use are at least 12 Inches wide which gives you plenty of cover on both sides around 6 inches per side I have never heard of these being used correctly and causing issues I’ve been in the industry long enough now worked with over nearly 10 different highly established roofing firms and they haven’t heard of such an issue either.
