More litto (lat) fitting today. Got to the join of the roof and the spacing has worked out just right, but I think I was probably just lucky, although I did actually work it out before I started, I didn't expect it to be right. Pitch perfect too, to coin an old musical thingy. Need some more litto and the flashing kit for the velux before I can continue, I'll get them tomorrow and carry on in the afternoon if the weather stays fine.
