What is Sheathing On Roof?
The sheathing on roofs is the most outer layer of material that covers the roof structure. It is generally made from plywood or oriented strand board (OSB) which serves as a base to install roofing shingles, metal roofing, or other exterior finishes. It also shields the roof from elements such as weather and the elements.
It is crucial to understand the role played by sheathing in roof stability and performance. Here are a few things you need to know about roof sheathing
The span of trusses and rafters determines the amount of sheathing. For instance, rafters which have a diameter of 16 inches can typically support sheathing that is 1/2 -inch thick. For 1/4-inch sheathing, you'll require eight nails as well as for 1/2-inch sheathing you will require six nails.
The importance of roof sheathing
The kind of plywood or OSB used for roofing sheathing is also crucial. The roofing experts typically recommend using plywood instead of OSB because it's less likely to delaminate ( tear apart) when exposed to moisture. CDX plywood is a great option for roofing. It is available in thicknesses ranging from 1/4 to 1/2 inch and also has an exposure rating. It is the length of time it can remain exposed to the elements , without needing to be covered. This can range from 15 minutes to an hour. OSB sheathing is offered in different thicknesses and exposure rating. But, OSB sheathing has fewer pieces of wood that are glued together so it is more vulnerable to delamination.
