Wastage is the term used for the amount of unusable slates you would expect

It varies for the type and grade of slates

Fibre cement slates have a typical wastage of 2.5%

Prime grade slate would have 5 % wastage, which climes when you have alot of cutting due to a difficult roof design

Standard/Heavy/Heritage also have a 5% wastage which can also clime due to the amount of cutting needed, typically standard grade will have a higher % wastage that Prime grade slates

You should expect about 1% to 2% wastage in the crates

Slates

Thanks for the post

Assuming you dont have to cut any slates for angles or none break/crack should there be any wasteage?

What about slates that are as bent as an S hook?
