What You Need to Know About Roof Decking

Also known as roof sheathing, roof decking is the material that acts as a foundation for the underlayment and shingles. It’s also what connects your roof to the framing of your house. Since it’s not usually visible, homeowners tend to miss early signs of damage. To prevent having to deal with a leaking roof, make sure to have your system regularly inspected.

Read on to learn more about this important roofing component.

What Is It For?

An asphalt roofing system can weigh hundreds of pounds. Then there’s also the layers between the shingles, which can add more load to your roof. The decking supports all the weight on a roof and helps distribute it throughout your home’s structure.

The flame retardants on the decking material can provide added protection in case of a fire. However, some roofers believe that they can affect the efficiency of the decking. Make sure to ask your roofing contractor about their policies when it comes to applying fire retardants. Further, the decking is also another line of defense against leaks.

Should You Also Replace Your Decking When Replacing Your Roof?

While it’s not necessary to have the decking replaced during a roof replacement, you should have it thoroughly inspected by a skilled roofer. Once the shingles have been removed, the decking should be checked for rot, dry rot, and flexing of the boards. A damaged decking must be replaced to avoid costly repairs for moisture-related issues.

Preventing Attic Moisture

Excess moisture in your attic can cause various problems to the roof sheathing. Warm, moist air that gets trapped in your attic can encourage mold and mildew growth on the decking. During your roof inspection, make sure your contractor checks the condition of the roof ventilation and problems that could develop due to excess moisture.
