In one form a timber clad roof consists of a fully watertight membrane applied to a plywood clad roof with timber battens installed over insulation and castellated timber batten.

Design of timber cladding details. Detailing of breather membrane and roof covering junction is as typical but care must be taken not to restrict ventilation to timber and or external wall cavity. Timber cladding should provide adequate weather protection for the buildings. Vertical timber cladding can come in the form of tongue and groove or board on board along with open joint options too.

Shingles are thin pieces of wood sawn on either side creating a smooth flat surface that is rather uniform in effect. The boards are nailed to vertical battens on the substrate this could be masonry timber frame etc. Detail design timber cladding basic principles in principle any timber cladding should be designed as a rainscreen. Horizontal timber cladding is probably the most common and perhaps simpler option.

Assuming that the cladding will always be subject to some penetration of moisture a separate protective membrane will be necessary behind the cladding largely protected from wind rain and daylight by the cladding itself.

It should be raised away from the ground by a minimum of 250mm to avoid excessive damage at the splash line at ground level and a good roof overhang should be provided to minimise the impact of weathering.

Details on plan 1. However it must be assumed that not all wind driven rain will be deflected. Folded ridge ventilating ridge detail at eaves external gutter valley details detail at gable. Drainage of external wall cavity must also be maintained see fig a 8 9.

As a consequence a well ventilated free draining cavity should always be included in the detailed design. Timber cladding for roofs primarily comes as either shingles or slates each with their own individual aesthetic.
