Eaves

Dress underlay into gutter and pull tight to ensure no water retaining troughs and support with tilting fillet. Fix undereaves and eaves course of slates with tails aligned and projecting 45 mm (minimum) to 55mm (maximum) beyond the fascia tilting fillet or wall face. Longer slate nails may be required at the eaves courses.

Verge on Bargeboard

Ensure that undercloak and underlay are well lapped. Nail undercloak fair face down, to a true line and projecting 38mm (minimum) to 50mm (maximum) from face of bargeboard. Fill the gap between undercloak and slates with mortar, and strike off to give a neat, flush joint. Mortar for bedding and pointing, 1:3 cement:sand pigmented to match colour of slates.

Verge on Brickwork

Ensure that undercloak and underlay are well lapped. Bed undercloak in mortar fair face down, to a true line, projecting 38mm (minimum) to 50mm (maximum) beyond face of wall, and point neatly to match in with joints in walling. Cut verge slates as necessary and fix flush with undercloak. Fill the gap between undercloak and slates with mortar, and strike off to give a neat, flush joint. Mortar for bedding and pointing, 1:3 cement:sand pigmented to match colour of slates. Note:Where possible use slate-and-a-half slates to alternate courses to form verges.

Mitred Valley

Cover with a strip of underlay 600mm wide, underlapping general underlay. Cut slates neatly and accurately and interleave with lead soakers to form a straight, close, weathertight mitred junction. Fix soakers by nailing to battens at the top edge. Minimum recommended pitch is 50º, for pitches below this please contact Slate UK Technical Department.
