Roof join using ridge tiles

My neighbour has had a new roof. Previously our tiles were tied together. They have said her roof is higher so have used ridge tiles to cover the gap. Is this allowed? All other houses in the road are tied together even with a new roof.

"Hi my name is Rob and I own RDC Property maintenance, to be honest, your ridges should still match up even with your neighbour having a new roof unless the trajectory of the roof has been changed I.e new wooden trusses fitted"

"As long as they have used soakers in between each course of tiles. But the centenary will fail so a bonding strip might have been a better option"

"We would never use ridge tiles if the new roof is higher or a different tile type we would use a bonding strip between the two roofs this also acts as a water channel/ valley"

"Should be tiled together. Especially since the roof was tiled together in the first place."

"The correct way to join two separate roofs using different tiles is to use a fibreglass bonding gutter, if the tiles are the same there is no reason not to tie in with the existing ones. You should never ridge vertically on slates as water will track underneath and will definitely leak."

"Seems like they have changed the profile of roof covering so should have come under building control"

"There’s a couple of options this being one. Also could have used a grp joining strip. Can’t understand why the roofs are different heights now? Unless they are different tiles or one roof is slate"

"You can use a fibreglass tray that separates both house tiles or you can cement the ridges together depending on if the tiles lock in together"
