It is essential that all three points of contact are engaged.When used at a top edge abutment, or similar situation, a lead flashing should be dressed over the head of the top verge unit. The flashing length will be dependent on the rafter pitch.At the ridge, a Ridge Comb Closer should be used to prevent the ingress of birds.Where timber sarking is used over the main roof area, the tiling battens should rest on the extreme brickwork or cladding. Suitable for 25mm thick batten only.Ambi-Dry Verge units for Cambrian and Stoneworld II are fixed by Verge Clips included in the pack.
