What You Need to Know About Your Roof’s Decking

Your roof is an intricate system of various components that work together to ensure your home’s protection against the elements. One of the most important—and often overlooked—parts is the decking or sheathing. Today, High Performance Homes, your local roofing, window and door installation experts, explains the things you need to know about it.

What Is the Roof Decking?

The decking is applied over the roof’s framework that is made of trusses and joists. It serves as the inner layer of the roof, protecting your home from the elements. Roofers then apply the waterproof underlayment on the decking’s flat surface, followed by the roof covering—asphalt shingles, metal panels or clay or concrete tiles—to complete the roofing system.

The Many Purposes of Roof Decking

Your roof’s decking serves numerous important purposes. For one, it is capable of supporting the weight of the roofing materials, including the roof covering and the underlayment. Also, it can withstand fires as long as a flame retardant is sprayed on the decking surface. With its strength and durability, the decking can also keep moisture out, preserving your roof’s health and performance.

Roof Decking Types

Innovations in the roofing industry paved the way for better, long-lasting roof decking. Before 1970, plank sheathing was used to cover the roofs’ framework. Fast forward to today and top rated roofing companies utilize either plywood or oriented strand board (OSB) as sheathing.

Plywood decking sheets are usually rigid and moisture-resistant and are sourced from mature trees. OSB sheets, meanwhile, are created by interweaving wood strands, which then undergo thermal pressing to bond them together and form a uniform surface.

For Cameron and everyone, again I say thank you! NW Natural has just recalculated our “equal pay” bill and we’ve gone from $67.00/month to $38.00/month. This is a savings of $348.00 per year plus the electric bill never once exceeded $90.00/month this summer saving us about $300 this year just is savings with the A/C. The windows remain beautiful, functional and more than everything promised! That and a leak free roof, who could ask for anything more! Thanks again!

“This contracting company recently replaced all the windows in my home. All of the associates I interacted with along the way were pleasant, knowledgeable, and professional. The way the windows were installed was done with precision and care for my home, and I did not have to pay any extra for trim around both the outside and inside of the windows. The end result is pleasing to look at, and I can already tell there’s a big difference in how insulated my home is.”
