Welcome to Bio-One Atlanta's comprehensive guide on roof decking and sheathing.

In this article, we will delve into the various types of roof decking and sheathing, discuss replacement methods, and provide valuable tips to ensure the longevity of your roof.

Types of Roof Decking and Sheathing

Roof decking and sheathing are essential components that provide structural support and serve as a base for the roof covering. Different materials are used for decking and sheathing, offering distinct advantages and considerations:


Plywood is a commonly used material for roof decking and sheathing due to its affordability and durability. It is made by bonding multiple layers of wood veneers together, creating a strong and stable panel. Plywood is available in various grades, thicknesses, and sizes to suit different roofing requirements.

Oriented Strand Board (OSB)

OSB is another popular choice for roof decking and sheathing. It is made of compressed wood strands, providing excellent strength and moisture resistance. OSB panels are typically less expensive than plywood, making them a cost-effective alternative.

Wood Boards

Traditional wood boards, often made of solid lumber, were commonly used for roof decking in the past. While they offer a natural aesthetic appeal and are suitable for certain roof types, they may require more maintenance and are prone to warping or cupping over time.

Replacement of Roof Decking and Sheathing

Over time, roof decking and sheathing may require replacement due to damage or decay. It is important to identify signs of deterioration to prevent further structural issues. Here are some key indicators that replacement might be necessary:

  • Water stains on ceilings or walls
  • Sagging or uneven roof surface
  • Warped or rotted decking/sheathing panels
  • Signs of pest infestation

If you notice any of these signs, it is crucial to consult a professional roofing contractor, such as Bio-One Atlanta, for a thorough assessment. Our experienced team will determine the extent of damage and provide expert recommendations for the replacement process.

  1. Regular Roof Inspections: Schedule annual roof inspections to identify any potential issues early on and prevent major damage.
  2. Prompt Repairs: Address any damaged or deteriorated sections of decking or sheathing promptly to avoid further structural problems.
