TapcoSlate Classic Fixing Guide

For felt and batten roofs, start by fixing battens minimum size of 2" (50mm) by 1" (25mm) treated battens over underlay to the required gauge. The first course and eaves (starter) course should oversail the fascia by at least 1½" (38mm), so the first course batten should be placed approximately 7½" (190mm) centrally from the start of the roof (see diagram). A second batten should then be placed directly under the first course batten to accommodate the eaves or starter course (made from a cut ¾-slate).
