Roof decking, also known as sheathing, is a layer of wood or composite material that provides a solid foundation for your home’s roofing system. It sits between the structural framing and shingles, helping distribute the weight of your roof and protecting your home from the elements. In residential applications, the most popular types of decking are plywood and oriented strand board (OSB). Although you can’t see roof decking from the outside, it’s vitally important to the structural integrity and stability of your roof. It helps distribute the load of snow and foot traffic, and it provides a barrier against moisture and pests. If it’s not in good condition, your roof could experience leaks, sagging, or even structural failure. Scroll down to learn how to tell when your roof decking is damaged.
Diagnosing Damaged Decking
If you’re concerned about the structural integrity of your roof decking, schedule a roof inspection. A professional can examine your roof and provide expert reassurance that it’s in good condition — or, they can let you know that it is damaged and requires repairs. Either way, you’ll be able to rest easy knowing a professional has evaluated it.
That said, maybe you have no reason to believe that your decking is in bad shape and you’re simply curious about the signs you should watch out for. In that case, here’s how to tell when your roof decking is damaged:
Checking the Interior
To start, take a careful look at the interior of your house. Is the ceiling sagging anywhere? Are there any water stains? (These might look like brown or yellow splotches, damp patches, bubbling paint, or peeling wallpaper.) Have you noticed any leaks? Do you see mold or mildew? All of these signs point to water damage, likely caused by compromised roof decking.
Checking the Exterior
Next, step outside and review the exterior condition of your roof. Is the roofline sagging? Does it appear warped or uneven? Have you ever felt soft or spongy spots while walking on the roof? All of these signs indicate that your roof decking may be rotting or deteriorating. Do you see any missing or curling shingles? If your decking is damaged, it may be causing your shingles to loosen or buckle.
Checking the Attic
Finally, if you feel comfortable doing so, climb up into the attic. Do you see any sunlight peeking through the roof? This means there are likely holes in the decking that need to be repaired. Is the insulation damp or compressed? This could be caused by moisture damage related to a decking issue. Have you noticed a musty, damp smell? This could also be a sign that water is entering your attic through rotting, punctured, or otherwise damaged decking.
