How are wood planks and wood boards differentiated in roofing?

Wood planks and wood boards are differentiated primarily by their thickness and length. Generally, the term "plank" refers to a thicker and wider piece of lumber, while "board" is used for thinner and potentially narrower pieces. This distinction is important in roofing, as different thicknesses and dimensions will influence both the structural integrity and the visual aesthetic of the roof.

For instance, thicker planks are often utilized in applications where greater strength and durability are necessary, such as in certain roofing styles or when supporting heavy loads. Conversely, boards, being thinner, may be used for decorative purposes or in lighter roofing systems. Understanding these differences helps roofers select the appropriate material for specific applications based on building codes, architectural requirements, and performance needs.
