Hello, it depends on where you are installing it, indoors or out. If outside, does the area get wet at all or face west and get all the weather? If so, I would want plenty of headlap if you are depending on the slate to shed water. If indoors or out of the weather, I would think anything goes as long as the nails are covered and it looks good.

you could consider augmenting the minimal headlap with some 15 lb felt similar to the way it's used in wood shingles- it might not cause more problems than it solves- as repairs, etc. are less likely(or necessary) on a vertical surface?

I've used 1/2" headlap with 12" random-width slates on a square of vertical wall under a peaked garage roof (~1ft roof overhang; sheltered from driving rain) and so far, so good!

I have done some slate siding with about 1' head lap. The only think with doing that with used slate is the shadow lines on the used slate show.

Hi, I have the opportunity to buy some salvaged slate (from a roof in Lowell, MA) which is 11" wide by 10" high. In order to install these slate with the recommended 3" headlap, there would only be 3-1/2" of slate showing per course. I'm assuming that the recommended 3" headlap is relevant in both slate roof and slate siding situations. My question is as follows..."What headlap should be used in vertical slate siding?" Thanks.
