Your roof is a complex system that is made up of materials that work together to protect your home from the harsh elements. One of the most important—and least talked about—components is the roof decking or sheathing.
About Your Roof Decking
A residential roofing system has trusses and joists that serve as the framework of the whole structure. These, however, are just a frame with empty spaces in between. This is where roof installation pros apply the decking. It provides an extra layer of protection between your roof and your home. Also, it provides a flat surface for the weatherproof materials like the underlayment and roof covering to attach to.
Types of Roof Decking
This roof component is a classic example of innovation in the construction industry. Before 1970, homes were built using plank sheathing as the covering for the roof framework. Today, residential properties either have these two roof deck types—plywood or oriented strand board (OSB) sheathing.
Plywood sheets are typically 4 inches by 8 inches long. They are sourced from mature trees and are moisture-resistant and rigid. OSB sheets, meanwhile, can be longer than 16 inches. They are created by interweaving wood strands that are then bonded together via thermal pressing for a uniform surface.
Decking and Roof Replacement
If you are tackling a roof replacement project, you might be wondering if the roof deck is also replaced. That would depend on the material’s structural integrity. The roofing pros would have to examine it for rot or dry rot, as well as if it bends when walked on. Decking that is in good condition will remain; otherwise, it will also be removed along with the old roofing material.
Sometimes, determining whether the deck is in good condition starts once all shingles have been removed. Roofers may also access your attic or crawlspace to check the deck’s underside to have a good sense of how it is holding up. Either way, reputable roofers will add information into their contract about the potential need to replace damaged deck sections.
