Timber Clad Roof Detail

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.

Details on plan 1. Tile hanging off timber frame 1 8. Some typical detail for a timber cladding roof can be found here with a timber board fixed to batten over a membrane clad plywood roof. The boards are nailed to vertical battens on the substrate this could be masonry timber frame etc.

Timber roof cladding is one of the best ways to accentuate your home or building. Figure a 8 9typical closed deck timber frame balcony detail at a penthouse level. 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. The inner wall structure should be fitted with a breather membrane.

Timber cladding for roofs primarily comes as either shingles or slates each with their own individual aesthetic. Shingles are thin pieces of wood sawn on either side creating a smooth flat surface that is rather uniform in effect. This serves to seal the building against damp and weather penetration. Vertical timber cladding can come in the form of tongue and groove or board on board along with open joint options too.

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. Non loadbearing wall junctions 1 5. Design of timber cladding details. Separating wall junctions 1 4.

Horizontal timber cladding is probably the most common and perhaps simpler option. Detail design timber cladding basic principles in principle any timber cladding should be designed as a rainscreen. Drainage of external wall cavity must also be maintained see fig a 8 9. As such it should be highly durable and tear resistant in accordance with type 1 membranes in bs4016.
