how are you finishing the ridge?

saddle, cap metal, something else?

you need to subtract the exposure of the cap material, then divide by the number of courses you need.

if your ridge finish is 8", you have a total of 64.

12 courses will run 64" AT 5 1/3"

So a slight shrink in exposure rate will net an even layout, and maintain headlap.

Starting a new roof with 8 x14" slates, and wanted to know how to calculate the spacing for each row so that I don't end up with a sliver of slate at the ridge. I know the max spacing will be 5 1/2" to keep 3" minimum headlap. What is the best way to determine the row spacing to end up with a good situation at the ridge. The distance from the bottom of the starter slate to the ridge is 72".
