I'm looking to get a few replacements of the tile attached as image. I don't know where to start trying to find a replacement tile. The tile is roughly 23cm x 24cm, it joins two sections of roof, it isn't a ridge tile but I'm not sure what you call it. I've lost two recently to the wind. Access is good to the roof, so diy is safe.
I'm assuming getting a roofing company, they would have access to these tiles but I'd like to try and diy this if possible.
Any suggestions would be gladly received, regards.
