Your roof is a shield, your home’s first line of defense against the elements, and ensuring its integrity is paramount. During a roof replacement, the question of whether or not to replace the roof decking may come up. Let’s delve into the factors that influence this decision and help you understand when replacing the roof decking is necessary.

Understanding Roof Decking: Your Roof’s Foundation

Roof decking, also known as sheathing, provides structural support and serves as the base for your shingles and underlying roofing materials. Over time, factors like weather, age, and moisture can affect the condition of your roof decking.

When to Consider Replacing Roof Decking: Signs and Indicators

  1. Water Damage: If your roof has experienced leaks or water intrusion, the decking may be compromised. Water-damaged decking loses its structural integrity and can lead to more severe issues if not addressed.
  2. Microbial or Rot: Discovering either of these bad boys on the roof decking is a clear indication that replacement may be necessary. Microbial growth and rot can spread, jeopardizing the entire roofing system and potentially affecting the structural integrity of your home.
  3. Age and Wear: Roof decking has a lifespan. Over the years, it can weaken due to daily expansion and contraction caused by sweeping temperature and humidity changes. Another factor may be the number of times your roof has been replaced over the history of your home. There are times it might be prudent to replace the decking along with the roofing materials to ensure a solid foundation for the new roof.
  4. Pest Infestation: Uninvited guests like termites, raccoons, squirrels or other pests can compromise the integrity of the roof decking. If pests have intruded, replacing the damaged decking is key to preventing further expensive and inconvenient interior damages.
  5. Code Compliance or Manufacturer Requirements: Some building departments may require upgrades to meet current building codes. Periodically we run into homes with 1’x 6’ roof boards, or shiplap. Over the years these roof boards dry out, contract and even twist – leaving gaps in the roof decking. In these instances, re-decking is critical to provide a “nailable surface” for underlayment and shingles to be reliably fastened to the decking. Most shingle manufacturers cannot honor a materials warranty if the roof is installed over plank roof boards.

When Roof Deck Replacement May Not Be Necessary

  1. Minimal Damage: If the decking is in good condition with minimal damage and meets current building standards, replacement will not be necessary. A thorough inspection by a roofing professional can help determine what to expect during your roof replacement.
  2. Budget Considerations: In some cases, if budget constraints are a concern, and the decking is deemed structurally sound, it may be possible to reuse it during the roof replacement. However, this decision should be made considering the long-term implications for the homeowner.

The Professional Assessment: Your Guide to Informed Decisions
