Timber shingles and shakes have been used as a lightweight roof cladding in New Zealand for around 200 years. They are mentioned in current design guides for many heritage areas, but they are also found in contemporary styles of housing.
Shingles are sawn and have relatively smooth faces. They usually have random widths and taper in thickness.
Shakes are usually hand split (although some are also sawn) and usually have a rougher textured surface on at least one side. Widths are generally random. While shakes also taper from a thick to a thin end, they sometimes have a thicker butt end than shingles. This creates a more visible shadow line.
Shingles and shakes are usually manufactured from residual timber left over from the main forest log production. They have a relatively small carbon footprint compared to some other roofing materials. Many of the plantation forests they are sourced from are certified by the FSC (Forest Stewardship Council) or PEFC (Programme for the Endorsement of Forest Certification).
