Wood shakes and wood shingles are typically manufactured from red cedar, cypress, pine and redwood trees. They are split from logs and reshaped by manufacturers for residential and commercial use. They vary in thickness, texture, length and width based on the style and appearance desired. Wood shakes are thicker that wood shingles and give a more random and textured look on the roof. Building codes and geographic locations must be taken into account when considering the use of wood roofing products to ensure that proper fire or preservation treatments have been included.
