- Sarkings are weatherproof membranes laid over rafters and below battens to draught-proof and weatherproof the roof against driving rain or powder snow that may penetrate the tiles or slates.
- Traditional sarkings of reinforced bitumen felt have been largely superseded by lighter, breathable sarkings that can be laid to form an effectively draught-proof roof but still allow free dispersal of water vapour to avoid roof space condensation; such mterials generally avoid the need for eaves, ridge and roof slope ventilators. Where they are laid directly over insulation between rafters, or over a permeable sarking board, tiling battens are raised clear of the sarking by 25 x 50 counter battens nailed down to the tops of the rafters.
