Roof decking (also known as sheathing) is the foundation for your roof. It acts as the link between your house and the roof. It is the base on which the attic and the entire roofing system rests. Any damage to your roof deck, in the form of leaks or rotting, can seriously hamper the structural integrity of your Memphis, TN roof.

The Ultimate Guide to Understanding Your Roof Decking

The Materials of Roof Decks

In most cases, a home’s roof deck is made of Oriented Strand Board (OSB). It is a composite of plywood and intertwining wood strands, glued together by an adhesive resin. Some roof decks also use plywood, although it is more expensive it provides greater moisture protection than the OSB.

Why Do Roofing Decks Rot?

Mostly, it occurs due to the accumulation of water on the deck. Since the roof decks have wood in them, they are susceptible to rotting caused by water accumulation. Even if there is no accumulation of water, continuous exposure to water and excess moisture can cause it to rot.

This seepage of water into your roof deck can occur due to a variety of reasons. Some of these may include broken or damaged asphalt shingles, torn flashings, accumulation of snow, and excess humidity in the attic, among others. The presence of moisture in your roof decking is extremely risky as it can cause structural damage, and even lead to fires if the water comes in contact with electrical wiring.

How do you Spot a Rotting Roof Deck?

Look for the following signs. And, if you notice any one of these, get in touch with professional roofers immediately.

  • If water is leaking from your roof continuously, it may be time to inspect your roof deck to see if it has excessive moisture buildup.
  • Wet spots on your ceiling. This is a direct consequence of a roof leak. You might even see dark spots on the ceiling or holes that may have been caused due to continuous exposure to moisture. Do not ignore this, as it may become a breeding ground for moss and mold.
  • Other signs may include – Wallpaper peeling, sagging ceiling, and the formation of mold in your attic, etc.

According to the National Roofing Contractors Association (NPCA), you must inspect your roof at least twice a year, once after the fall, and after the spring. Do not do it yourself, hire an expert roofing contractor to do the job. You must also have your roof inspected after any adverse weather situation throughout the year, like a storm, hurricane, heatwave, etc.
