The eagle eyed among you, or perhaps just the un-dopey will have realised I made a balls of installing the velux. I woke up this morning and I realised I'd done it wrong, I must have been thinking about it in my sleep. Anyway the problem was I had installed it too low and the flashing would have gone under the tiles, so I had to remove the whole velux and raise it a couple of inches. 'Tis done now anyway.
