Why You Can’t Repair a Damaged Roof Deck

Larry Walty II • December 2, 2022

A roof deck or sheathing refers to the material installed above the rafters and below the underlayment. It is commonly built using plywood or oriented strand board and performs a crucial function in keeping the structural integrity of your roof. Our roofers discuss here the telltale signs of a damaged roof deck and why you cannot repair it.

Common Signs of a Damaged Roof Deck

While you need the assistance of a professional roofing contractor to confirm whether or not your roof deck is damaged and needs repair, there are some telltale signs you can watch out for without having to climb on your roof. These include:

  • Mold and mildew growth in the attic
  • Holes or cracks in the roof
  • Curling or missing shingles
  • Sagging roofline
  • Excessive shingle granule loss
  • Deterioration around vents, skylights and other fixtures on the roof
  • Water stains or discoloration on the ceiling and walls

What You Should Do About a Damaged Roof Deck

A roof deck repair is simply a no-go. For one, the deck is primarily made with wood, and when affected by water infiltration — the main culprit behind deck damage — it is only a matter of time before rot ensues. Even if the affected boards are fixed, there is no guarantee that rot will not develop again. In this case, it makes practical sense to have the deck completely replaced along with the shingles. Ideally, you want a material that is tough and waterproof for your sheathing. A trusted roofing company can help you explore your options and decide on the best one that fits your needs.
