Final answer:
Modern OSB roof sheathing typically should not be thinner than 3/8 inch, with common thicknesses at 7/16 inch, 1/2 inch or 5/8 inch. It's crucial to consult local building codes and manufacturer recommendations, which might specify minimum thickness requirements based on truss or rafter spacing.
Step-by-step explanation:
The thickness of OSB (Oriented Strand Board) roof sheathing can vary depending on the application and building codes, but modern OSB used in roofing typically should not be thinner than 3/8 inch. Modern OSB roof sheathing typically should not be thinner than 3/8 inch, with common thicknesses at 7/16 inch, 1/2 inch or 5/8 inch. It's crucial to consult local building codes and manufacturer recommendations, which might specify minimum thickness requirements based on truss or rafter spacing.
However, the most common thicknesses used for roof sheathing are 7/16 inch, 1/2 inch or 5/8 inch. It's important to check local building codes and manufacturer recommendations, as they may specify the minimum required thickness based on the spacing of the roof trusses or rafters. The use of thinner sheathing may compromise the integrity of the roof, especially in regions with heavy snowfall or high winds.
