18" shakes on a Roof?

A few years ago I bought about 50 bundles of 18 hand split shakes. I want to buy more to re-do the roof on my house.

Can I use 18 in shakes on a roof. I don’t know the exact pitch but is is not high pitched.

Totally depends on the pitch. I would not recommend them on anything less than a 4/12 but I have seen them on lower. There is stuff you can do to put them on very low slopes but imo it’s dumb, they don’t belong there.

Run them on a 7" course.
