Despite adding some cement dye to my the mortar I used to bed the ridge tiles and bonnets on my new extension, it still stands out dreadfully against the existing roof pointing.
The existing roof has a very fine layer of black growth over it, even on the tile actually. Can I encourage this on the new pointing? Dilute yoghurt spray? Maybe I need more to worry about in life!
Cheers
