Wood shakes or shingles are generally exposed to the elements for what purpose?

Wood shakes or shingles are primarily used for aesthetic appeal, enhancing the visual character and overall design of a building. Their natural textures and colors add to the architectural style, giving structures a rustic or traditional look that many homeowners and builders seek.

While they may offer some degree of insulation and energy efficiency, these are not their primary functions; rather, those qualities more commonly stem from materials like insulation batts or foam. Similarly, wood shakes and shingles do not serve as structural support; instead, they are intended to work as a protective exterior layer that contributes to the building's appearance while providing a level of weather resistance. The primary role of wood shakes and shingles revolves around their contribution to the aesthetics of a building.
