3 Things Homeowners Need to Know About Roof Decking

Planning on having your roof replaced? Don’t forget about your roofing system’s decking – the base of your roof is just as important as the shingles attached to it. 

Here are the things you should know about roof decking: 

1. You Don’t Necessarily Need to Have New Decking Installed When You Get a Roof Replacement

It all depends on the condition of your roof decking. A roofer will need to inspect the underside of your deck for signs of damage through the crawlspace or the attic. Keep in mind that while the underside can give roofers a good idea of the condition of the decking, this inspection method isn’t completely accurate. As such, there’s still a chance your roofer might discover signs of damage when they remove shingles. 

2. There Are Several Types of Roof Decking

Picking a type of decking that’s suited to your area’s climate can reduce the risk of moisture damage. The three most common types of decking are: 

1. Oriented strand board (OSB) – OSB, the most common type of decking, is composed of intertwined wood strands that are bonded with a waterproof resin. 

2. Plywood sheathing – This type of decking is denser than OSB and more resistant to moisture and rot damage. 

3. Step sheathing decking – Step sheathing deck boards are spaced a few inches apart from each other to allow air circulation underneath the deck boards. 

You can also consult a contractor to find out which type of decking is best suited to your area’s climate. 

3. The Roof Decking Serves as a Secondary Layer of Defense Against Moisture

The roof decking’s primary function, being the base of your roof, is to ensure weight is distributed evenly throughout the roofing structure. However, decking that has waterproofing materials attached to it also serves as a secondary layer of protection against water.
