In many countries, including Scotland, it is usual to 'sark' the roof with a covering of timber boards or sheet composite over the rafters. However, in England and Wales it has become common practice to leave out the timber and use only a 'sarking felt' over the rafters and below the tile battens.
In our view, this can be a false economy, since timber or sheet board sarking acts as a racking membrane and can eliminate the need for timber bracing, while providing an overall stronger and better insulated roof.
Using a sarking board also opens up the way for exposing the underside of this board and the roof timbers, since it becomes possible to support the timber frame roof insulation material on the top side of this.
