Roof decking is the solid surface to which the shingles or other roofing material is attached. Typically, the decking comes as sheets of plywood, wood boards, or planks. More recently, laminated roof decking has appeared on the market for situations in which the ceiling is exposed.

Lumber

Lumber used for roof decking, or sheathing, has to be graded at least No. 3 common. These typically softwood boards should be seasoned so that they will not shrink as they dry after shingles have been attached. For either pitched or flat roofs, 1-inch board will suffice unless the flat roof will double as a balcony. In that case, thicker boards are needed for the extra strength. The boards can run either horizontally or vertically. If horizontal positioning is chosen, the boards can be laid with no space (called closed) or with some space between each board. However, if the house is in a region that suffers from a great deal of wind-driven snow, it is recommended to leave no spaces. In addition, certain roofing materials will need a solid nail base, such as asphalt shingles, composition roofing, and sheet metal shingles. Spaces can be left if using wood shingles, but only if it is in an area that has no blizzards.

Plywood

Plywood is a more economical choice than boards for roof decking. Since plywood comes in 4 X 8' sheets, a large area can be covered quickly. Plywood decking gives a solid nail base with fewer joints to cause potential problems. Plywood is used most commonly for roof decking because of its affordability and easy installation. The thickness of the plywood will be decided by rafter spacing (longer spans need thicker plywood), the weight of the roofing material (heavier shingles need thicker plywood0, and typical ice and snow accumulation (heavy accumulation will need thicker decking).
