Why Roof Decking Matters: The Foundation of a Strong Roof

Most homeowners don’t think about roof decking because they never see it. But this plywood or OSB layer supports your shingles and determines how well your roof performs over time.

Here’s why roof decking deserves attention.

What Is Roof Decking?

Decking is the wooden foundation your roofing materials are attached to. If it’s healthy, your roof stays stable. If it’s damaged, leaks and structural issues follow.

Signs Your Decking May Be Compromised

• A “spongy” feel when walking on the roof

• Visible sagging

• Persistent attic moisture

• Mold or rot

• Leaks that keep returning even after repairs

These issues often start small but spread fast.

Why Decking Fails

In Nashville, the most common causes are:

• Prolonged moisture exposure

• Poor ventilation

• Old age

• Storm damage or fallen limbs
