DIY projects can be attractive for homeowners looking to save money and take control of house roof repairs. However, when it comes to roof decking, having it repaired is not ideal. Premier Systems Roofing discusses the signs of roof decking damage and why it’s best to have it replaced.


Signs of Roof Decking Damage

Detecting early signs of roof decking issues can help prevent more extensive damage to your roof and the interior of your home. Here are some common signs that your roof decking may need repair:

  • Water Leaks. Water stains on your ceiling or walls indicate a roof leak, which could be caused by damaged or deteriorating roof decking.

  • Sagging Roof. A noticeable dip or sag in your roof’s surface might indicate weakened or rotted roof decking, compromising the roof’s structural integrity.

  • Curling or Buckling Shingles. If your shingles are curling or buckling, it could be due to inadequate roof decking support, allowing the shingles to become misaligned.

  • Visible Holes or Gaps. Check for visible holes or gaps in the roof decking. They can be caused by rot, pests, or damage from weather elements.

  • Increased Energy Bills. Damaged roof decking can lead to poor insulation, causing your heating and cooling systems to work harder. This results in higher energy bills.

  • Algae or Mold Growth. Algae or mold growth on the roof’s surface can indicate moisture buildup due to damaged roof decking.

  • Sunlight Coming Through. If you notice sunlight penetrating through while you’re inside your attic, it suggests there are gaps or cracks in the roof decking that need immediate attention.

  • Soft or Spongy Roof Surface. When walking on your roof, if you feel soft or spongy areas, it could be a sign of rotting or deteriorating decking.

  • Missing or Damaged Shingles. Missing or damaged shingles may expose the roof decking to the elements, leading to further degradation.

  • Age of the Roof. If your roof is nearing the end of its expected lifespan (usually around 20-25 years), inspecting the roof decking for signs of wear and tear is essential.

Why Isn’t a Roof Decking Repairable

The decking forms the base layer of the roof system, providing structural support and acting as a barrier against water and weather. But since it is covered by shingles and underlayment, it is impractical to perform spot repairs on it. To determine if this is the case, you’ll have to tear away the other roof layers.


Then again, it’s possible that the roof decking has been damaged if the aforementioned roof layers have been compromised as well. It is a clear indication that the roof system itself is no longer in the best shape, and the only course of action would be to replace it entirely with the rest of the roof’s components.

Work With a Professional Roofing Company

The good news is that moisture infiltration, which is the leading cause of roof decking damage, can be prevented through timely repairs and routine maintenance. Hiring a professional roofing company provides quality workmanship to ensure the long-term integrity of your roof, protecting your home for years to come.
