During times of high wind, sarking can move (flap about) causing increased noise levels. If a roof is likely to be subjected to high winds then consideration should be given to the use of security pads. These pads are made of a light foam rubber material and are fitted when the sarking is fixed in place. The pads are placed under the tile battens between each rafter, at every sarking lap joint. In all applications where sarking is installed, Harmony Roof Tiles includes the use of anti-flap pads.
