Wooden shakes and shingles are typically made from cedar boards and then treated to resist rotting and bug damage. Cedar shingles are uniformly cut pieces of wood, and cedar shakes generally are more imprecise in their shape and cut. Of all the traditional roof coverings, cedar shake is warm, organic, and rustic in a very stylish fashion! Cedar was once very popular for roofing and siding, as resources for old-growth cedar trees were abundant. Over time, that has changed, and today cedar roofing is more of a high-end delicacy of property owners and architects.
