Under strong wind gusts the uplift of the roof tiles may be in excess of the dead mass of the tiles, hence requiring them to be securely fixed to prevent them being lifted from the building.
The principal factors to be considered in deciding on the necessity for additional mechanical fixings are:
Where a building is complex in shape, located on steep sloping ground or near to the edge of a cliff, further advice should be obtained.
Recommended Nailing/Clipping as per requirements given in compliance with SR. 82.
For the purposes of selecting appropriate mechanical fixing, buildings in the following circumstances are considered to be exposed:
(a) any building which stands above its surroundings or has a ridge height in excess of 12 metres above adjoining ground level, or
(b) any building on a hill slope or hill top, or
(c) any building in a built up area which is subject to adverse wind effects, such as funnelling, or
(d) any building which is located in the green area of the map.
Severely exposed buildings
For the purposes of selecting appropriate mechanical fixing, buildings located in the green area of map which are in the following circumstances, are considered to be severely exposed:
(a) any building which stands above its surroundings or has a ridge height in excess of 12 metres above adjoining ground level, or
(b) any building on a hill slope or hill top, or
(c) any building which is subject to adverse wind effects, such as funnelling.
In summary, minimum fixing requirements for single lap tiles:
Pitch Fixing requirements

Pitch > 45° a) Normal building: every tile head nailed or tail clipped
and < 55° b) Exposed or severely exposed building: every tile head nailed and tail clipped
Pitch ≤ 45° a) Perimeter* area, normal building : every tile head nailed or tail clipped
*All tiles at eaves, verges, ridges, hips and tiles adjacent to valleys, abutments, chimneys, rooflights, etc.
