Final answer:
The correct size and species of the ridge board over a porch depend on the specific structural requirements and local building codes; common options include spruce, pine, fir, and cedar in various sizes.
Explanation:
The size and species of the ridge board for a porch cannot be determined without specific structural information from the building plans or construction details. Ridge boards are an important structural component in roof construction, serving as a backbone where the rafters meet at the peak of the roof. The size and material of the ridge board are determined by the load requirements, span of the roof, and local building codes.
Options like 2x6 Spruce, 2x8 Pine, 2x10 Fir, or 2x12 Cedar each have different strengths and may be specified based on the design requirements of the porch structure. It's essential for builders to consult the building plans, a structural engineer, or local building codes to select the correct size and species of wood.
