4 Signs That Your Roof Decking Is Damaged

Roof decking, also known as sheathing, is the plywood or composite material placed between your roof’s support structures and the shingles. This part of your roof is also where your protective underlayment is placed and to where your shingles are nailed. If your roof decking is damaged, you can expect several problems like leaks and structural integrity issues. 

To help you prevent these complications, here are four signs that you should look out for if you suspect your roof decking is damaged.

1. Visible Damage

Holes, cracks and penetrations on your decking are the most obvious signs of decking damage. Although roof decking is sturdy and meant to last for some time, strong weather can damage them when they’re already compromised or if there’s enough force involved. Debris hurled by strong winds can also damage your decking in various ways. 

2. Blown-Off or Buckling Shingles

Shingles are attached to the roof decking, and if they get blown off or buckle easily, there could be an issue with your decking. If the shingles aren’t attached to a stable and durable sheathing, they can buckle or get dislodged, so it’s best to have them inspected and replaced when necessary.

3. Inconsistent Utility Bills

Issues on your roof decking can also affect your utility bills. If your decking is letting more heat into the attic space, this can increase the temperature in the attic and leak the warm air into the living spaces below. This increased heat can strain your HVAC system, making it work harder to keep your indoors at a comfortable temperature.

4. Sagging or Bowing Roof Line

A sagging roof line indicates a major structural issue in your roofing system, and your roof decking can no longer support the weight of the shingles and other roofing materials. This can be due to wood rot or other forms of moisture damage.

Roof decking is better replaced than repaired because weakened sheathing is no longer reliable.
