Untreated cedar shingles are thin, overlapping pieces of wood, typically made from western red cedar or other cedar species, used primarily as a roofing or siding material. These shingles are left in their natural state without any protective treatments such as staining, sealing, or pressure treatment. Untreated cedar shingles have a rich, natural wood colour. The wood is known for its fine, uniform grain, which provides strength and durability.
