Why You Can’t Repair Your Damaged Roof Deck

Underneath the asphalt shingles is a layer of decking or sheathing that is commonly made of plywood or oriented strand board (OSB). Because it serves as the anchor for the entire roofing system, it must have the strength and flexibility to withstand the weather and the weight of the roof covering and other materials on top of your home.

Even when it is tucked away behind the underlayment and the roof covering, there’s still a chance that it will sustain damage. The Great American Roofing Company, the trusted contractor you can turn to for a free roof repair estimate, discusses more.

The Threat of Water on Your Roof Deck

Water is the number one enemy of your roof deck. If it suffers damage, it is often because of long-term exposure to precipitation or a result of water-related rot. You may find that this is the case if you notice any of the following signs:

  • Leaks

  • Interior wall stains

  • Sagging roofline

  • Punctures or holes on your roof

  • Mold and mildew growth inside the attic

  • Damaged flashings

  • Increased energy bills

From old roofing materials and damaged gutter systems to ice dam accumulation during winter to excessive humidity, these problems on your roof and in your home can cause water to seep into the roof and make its way to the deck. Leaving it unattended can increase the risk of the wooden components rotting, compromising the roof’s structural integrity.

Replacing Your Damaged Roof Deck

Most would assume that immediate repair of the damaged deck can help solve these issues, but that’s not the case. Your roofer will likely recommend replacing the whole thing. Even if the damage is located on a small section of the deck, there’s no guarantee that the unaffected areas will remain intact for long. Trying your luck with repairs will only cost you in the long run, which is why a deck replacement makes more sense. After all, you’d want a solid base on which to install your shingles.
