What Is Roof Decking and Why Does It Matter?

Understanding Roof Decking

Roof decking, also called roof sheathing, is the layer of structural panels that cover your roof framing and form the foundation for everything above. In most homes built in the past several decades, decking consists of plywood or oriented strand board panels attached to the rafters or trusses.

Everything that protects your home from the elements rests on this decking: the underlayment, ice and water shield, and shingles all depend on a solid, structurally sound deck to function properly.

What Damages Roof Decking?

The most common cause of decking damage is prolonged moisture exposure from a roof leak. When water gets beneath the shingles and underlayment, it begins to saturate the wood panels. Over time, the wood softens, develops rot, and loses structural integrity. Walking on severely compromised decking can be dangerous.

A roof that has been leaking for a long time may require partial or full deck replacement as part of the roofing project. This is why addressing a Roof Leak Repair promptly is so important. The longer water has access, the more extensive the deck damage becomes.
