as far as using the prepunched holes, i believe the smallest length slate you can use with a 4" headlap is 16". although you may want to check a sample piece cause i've had a couple batches of 16" slates with the holes punched too low for a 4" headlap. otherwise you're gonna have to do what old school said. good luck

Take a slate hammer and punch holes higher on the slate and then it will work!

thinking about building a barn with a 4/12 pitch, the minimum for a slate roof.
the book calls for a 4 inch headlap because of the reduced slope.
my question is, what is the minimum size(length) slates one can use and still get a 4" headlap under the nail holes.
i have a 12" piece of slate in my hands and it doesnt make it.
