If you’ve ever had your roof replaced, you might’ve heard the term “decking” tossed around. But what is roof decking, really—and why should Texas homeowners pay attention to it?
At Doc’s Roofing, we like to say your shingles are only as strong as what’s beneath them. And that’s where roof decking comes in. It may be out of sight, but it should never be out of mind—especially in our storm-prone Texas climate.
🪵 What Is Roof Decking?
Roof decking (also called sheathing) is the flat layer of wood or plywood panels that sits between your home’s framing and the roofing materials (like shingles or underlayment). It acts as the foundation for your entire roofing system—providing a solid surface for materials to attach to and keeping your roof strong and secure.
🔍 Why It Matters to Homeowners
Think of decking as the bones of your roof. If it’s weak, rotted, or sagging, your entire roofing system is compromised. Here’s why it’s crucial:
-
Structural Support: It holds the weight of shingles, nails, and sometimes even solar panels.
-
Moisture Barrier: Paired with underlayment, it helps prevent leaks from seeping into your attic or insulation.
-
Safety & Stability: Soft or deteriorated decking can lead to sagging, leaks, and even collapse in severe cases.
🧱 Common Types of Decking
In Texas, the two most common materials are:
-
OSB (Oriented Strand Board): A cost-effective, engineered wood panel made from layers of wood strands. It’s strong but more susceptible to moisture damage over time.
-
Plywood: Slightly more expensive but holds up better in high-humidity areas or heavy rainfall—common after Texas thunderstorms.
💧 How Decking Gets Damaged
You might have pristine shingles, but underneath, decking could be silently rotting away due to:
-
Roof leaks that go unnoticed
-
Poor attic ventilation that traps moisture
-
Storm or hail impact
-
Old age and wear
-
Improper past installations
🛠️ How We Handle Decking at Doc’s Roofing
When we replace a roof, we never just “reshingle and run.” Our team inspects the decking thoroughly. If we find signs of soft spots, warping, or rot, we’ll replace those sections before installing new materials.
This ensures your roof is Weather-Tough—not just from the top, but from the ground up.
🧾 Will Insurance Cover Damaged Decking?
Sometimes. If decking was damaged as a result of a covered event (like hail, wind, or falling debris), it can often be included in your claim. We’ll help document everything and work with your adjuster to make sure it’s not overlooked.
✅ Final Thoughts
Roof decking isn’t flashy, but it’s one of the most important parts of your roofing system. Ignoring it can lead to expensive headaches down the road.
