While years of exposure to harsh weather such as sharp-hitting hail, heavy snow, ultraviolet light and powerful winds can cause the deterioration of roofing shingles, the problem doesn’t stop there. The decking—the structural component located below the shingles—is also susceptible to damage. In this post, a roofing service professional discusses whether damaged decking should be repaired or completely replaced.
What Is Roof Decking?
Roof decking or sheathing is the layer of materials installed directly beneath the underlayment and above the rafters. It’s commonly built using OSB or plywood. Your roof deck plays a crucial role in protecting your home from weather-related damage by keeping rain and moisture out. It also assists with attic ventilation.
What Are the Signs of Damaged Roof Decking?
A worn-out roof deck can encourage the development of numerous issues, especially if the damage isn’t repaired immediately. According to siding manufacturers, some of the most common issues associated with damaged roof sheathing include:
- Water leaks
- Mold in the attic
- Rotting roof trusses
- Insect infestations
- Premature wear on the shingles
- Dark-colored stains on ceilings and walls
- Roof sagging that’s visible from the exterior
- Unusually high cooling and heating costs
Should Roof Decking Be Repaired or Replaced?
Since roof decking is made of wood, it’s vulnerable to rotting, and when it comes to rot, decking repair isn’t an option. The wood must be fully removed and replaced with new materials in order to avoid other troublesome issues like increased mold and mildew growth. While replacing a roof is often an expensive venture, it’s surely less costly in the long run than tearing down and replacing stained drywall, water-damaged electrical systems and waterlogged framing.
