When it comes to roof replacement, homeowners often focus on the shingles, but there’s more to a roof than meets the eye. Roof plywood, or decking, is a critical component of the roofing system and plays a significant role in the restoration process. In this blog post, we’ll delve into the reasons why roof plywood must be considered part of the roof replacement scope of repair when restoring a loss to pre-loss condition, and the industry standards that support this perspective.
When it comes to replacing a damaged roof, understanding the importance of each component is crucial. According to the International Residential Code (IRC) Chapter 9, Roof Assemblies, a roof assembly includes various essential elements such as the roof deck, substrate or thermal barrier, insulation, vapor retarder, and roof covering. The IRC outlines the design and construction of roof assemblies, ensuring that all components work together to create a functional and durable roof system.
The roof deck, typically made of plywood, is an integral part of the roof assembly. It provides the structural support and a suitable substrate for the application of new roofing materials. As the National Roofing Contractors Association (NRCA) states in its Roofing Manual, a roof deck must be smooth, straight, and free of irregularities such as significant humps or depressions before applying new roofing materials. If the roof deck is damaged or deteriorated, it must be replaced to ensure a suitable substrate for the new shingles.
The Roof Plywood’s Role in Roof Replacement
Roof plywood is essential for the structural integrity and support of a roof assembly. It serves as the substrate for the roof assembly, ensuring a smooth and straight surface for the application of new roofing materials. According to the National Roofing Contractors Association (NRCA), a roofing contractor must ensure that a deck’s surface condition is suitable for the application of new roofing materials, including shingles. Damaged or deteriorated decking needs to be replaced before applying new roofing materials to meet the current standard for reroofing.
The Case of Gutkowski v. Oklahoma Farmers Union Mutual Insurance Company
In this landmark case, the Oklahoma Court of Appeals determined that a roof is a unified product comprised of all its component parts and materials, including sheathing (decking) and shingles. The court rejected the insurance company’s argument that the wood shingles were a separate and divisible roof from the asphalt shingle roof, and held that the cost of removing and replacing the wood shingles with plywood decking should be covered. This is not legal advice, don’t be a fool!
The Importance of Replacing Roof Plywood for Pre-Loss Condition Restoration
The Gutkowski case highlights the importance of considering roof plywood as part of the roof replacement process. Replacing damaged or deteriorated decking is crucial in restoring a roof to its pre-loss condition and ensuring the structural integrity and longevity of the new roofing materials. By adhering to industry standards set by the NRCA, homeowners can trust that their roof replacement will be done correctly and comprehensively.

By understanding the importance of roof decking in the restoration process and adhering to industry standards, homeowners can ensure their roof is restored to its pre-loss condition, providing lasting protection and peace of mind.
In summary, the roof plywood or sheathing is an essential component of the roof assembly, as defined by the International Residential Code (IRC) Chapter 9.
