The Roof Decking: Everything You Need to Know

By Stacy Mellete

When it comes to the residential roofing system, homeowners think that they’re only made up of the shingles, flashing and the underlayment. While these components are important parts of the roofing system, roofing and hail damage repair experts say that there is one component that you should never forget about: the roof decking.

Here’s everything you need to know about your roof decking.


What is the Roof Decking?

The reason why some homeowners tend to forget their roof’s deck is because they don’t always see it. However, what some homeowners don’t know is that it’s a vital part of your roof’s structure because it not only holds your roof up but adds an extra layer of protection between your roof and the home while providing a surface for the weatherproofing materials to attach itself to.

Do I Need to Replace the Deck When I’m Replacing My Roof?

When you’re replacing your residential roof, you don’t necessarily have to replace the deck as well. During the replacement process, if your storm damage restoration expert finds that the decking isn’t rotting or dried out, then the deck will remain in place. However, if there are some parts that are severely damaged, then these portions will be replaced alongside the roofing system.

Is There Only One Type?

Contrary to popular belief, there are actually many kinds of roof decking. These include the tongue & groove, which can often be seen in homes that have no ceiling; plank sheathing, an old decking solution that is seen in homes built before 1970; and step sheathing, which is used when installing cedar shingles in your home.
