A slate roof is designed to shed water through the careful overlap of each individual piece. ⚒️
Proper headlap—the distance one slate extends beyond the slate two courses below—is essential to keeping water away from nail holes and the roof deck. The correct layout depends on the roof’s slope, slate size, and exposure.
Underlayment provides secondary protection, but it is not a substitute for correctly sized, spaced, and installed slate.
