What type of slate
Mate ive 19 years experience in roof slating and i can assure you when am doing historic slate work here in Scotland when using ballachulish...
so in other words you dont put in half cuts you get slate and half if your cuts are going below 150mm wide at abutments etc or generally anything...
Dosent matter what size the slates are the minimum width of slate clerk of works etc want you to use is 150mm wide they dont want people using...
Slate min is 150mm you don't get the correct sidelap if you use a piece of slate narrower
overhang the slate 50mm on the verge start slating from the straight side first and use slate and a half on the verges
the course that lands on the join you can dummy hook but nail those slates
post a picture
yeah that was a steep one lol
Heres some pictures of us staging out a roof with scottish style brackets so you get the idea
