Fort Worth Roofing: Article About Sheathing Options
Fort Worth roofing professionals have used plywood for many years as an affordable and efficient decking material. Recently, plywood has lost its popularity as a roofing material and is now being replaced with OSB and other roofing alternatives.
One reason for the changes is that even though plywood is inexpensive, it is more costly than other sheathing materials. OSB is cheaper than plywood and more uniform, which helps create a smooth surface for the roofing material. One downside associated with OSB is its susceptibility to water and moisture. It must be protected with a water barrier. Fiberboard is an even cheaper option, but it lacks the strength and durability of plywood and OSB. In areas where wildfires are a concern, fire rated plywood will still be used on most homes.
Plywood is made by taking wooden strips and binding them together using a resin. The resin may be mixed with a fire retardant material to make the plywood fire resistant. OSB, on the other hand, is made by taking strips of wood that have been finely shredded and compressing them into a solid and dense board. All of the strips are laid and layered in the same direction. This creates a grain pattern that is both consistent and uniform. Fiberboard is made by pressing wood fibers together in random patterns.

It is a mix between OSB and plywood.
Although OSB is cheap and creates a uniform surface, if it is not protected with a waterproof underlayment, it will quickly fall apart. Many homeowners opt to pay extra money for plywood to avoid moisture-related problems. Homeowners should check local building codes before selecting the sheathing material because some building codes allow OSB and plywood to be used interchangeably, whereas others require that one or the other be used. Plywood works especially well with heavy roofing materials like slate tiles. Fiberboard will not support the weight of these materials, and it will not stand up to high winds.
Sheathing comes in different thicknesses based on the weight of the roofing material it needs to support and the distance between joists it needs to span. Lightweight roofing materials use 5/16-inch plywood, whereas heavy roofing materials like clay or concrete will need at least a 1/2-inch-thick plywood deck.
It is important that homeowners take the time to research the sheathing material they will use on their roof. The material they use and how the contractor installs it will be determined by the climate where the homeowner lives, the type of roof covering they select and their budget.
