Roof Sheathing - Fine Homebuilding
https://www.finehomebuilding.com/project-guides/roofing/roof-sheathing
The two basic types of sheathing are solid sheathing and open sheathing. Solid sheathing provides a continuous surface at the plane of the roof. This type of sheathing is necessary for composition roofing and built-up roofing, which have no structural capacity themselves. Metal, tile, and shingle roofing may also be applied to solid sheathing. Solid sheathing: provides a continuous surface for roofing that has no structural capacity, such as composition or built-up roofing. It can also be used for metal, tile, and shingle roofing. Oriented Strand Board (OSB): economical, less prone to warping or swelling, but vulnerable to water damage and formaldehyde emissions. Plywood: lightweight, available in a range of sizes and grades, but expensive, high maintenance, and smaller panels than OSB. Concrete: high strength, fire resistant, long-lasting, but costly, high maintenance, and more manpower required. Skip sheathing: resistant to moisture, durable, less material required, but ineffective in areas with significant rain or snow.
