New roof issue

[Simon789]

Just found out that our roofer decided to change the tiles he was using due to supply issues, without informing us - initially using Sandtoft and switched to Medley. You can see this halfway up and on some of the cuts.

Apart from the appearance I'm concerned if there will be any issues where the tiles interlock as they are a slightly different shape.

He assures me it will be watertight.

Any advice appreciated.

Looks poor. Some are off bond anyway.
Why not at least keep each side the same tile .. I wouldn't accept it

Very poor. Totally different colour and how the hell has he lost the bond in the middle of the roof… almost at straight bond
