Over time, the roof decking may deteriorate due to various factors, necessitating a replacement. In this comprehensive guide, we will explore everything you need to know about roof decking replacement.
How Often Does Roof Decking Need to be Replaced?
The frequency of roof decking replacement depends on several factors such as the type of material used, weather conditions, and the quality of installation.

However, issues like water damage, mold growth, and structural weaknesses may require a replacement sooner.
Does Roof Replacement Include Plywood?
When undertaking a roof replacement project, it is essential to assess the condition of the existing roof decking, which is often made of plywood. If the decking shows signs of damage or deterioration, replacing it along with the roof covering is recommended. This ensures a new roof system with a reliable foundation.

Each material has its strengths and weaknesses, with plywood being a common choice due to its durability and versatility. Understanding the differences between these materials can help you make an informed decision when replacing your roof decking.

Any damaged or deteriorated sections of the decking are then replaced with new material, ensuring a solid and secure base for the new roof covering. Proper installation practices are crucial to the longevity and performance of the roof decking.
Common Reasons for Replacing Roof Decking
There are various reasons why roof decking may need replacement, including:
- Water Damage: Exposure to water infiltration can cause the decking to rot and weaken over time.
