Roof base with half-timber construction


Many years of inadequate roof maintenance can cause damage to the wooden structure, meaning that sections of it need to be replaced.

Whole wooden sections are replaced wherever possible, but there may be other places where a partial replacement of the timber is required. This can be done using a variety of jointing methods. The figure on the right shows an example where the half-timber construction has been replaced completely, while two beam ends have been replaced using a scarf joint and a fishplate solution respectively.

The figure also shows an example of a replacement roof covering using a rafter alignment and fixed subroof, which experience has shown to be a long-term solution.

Modern demands for comfort and low energy consumption mean that the roof structure often needs to be retrofitted with insulation if the roof area is to be used as living space.
