When planning a roof replacement project, you might come across the terms “decking” and “sheathing.” These components create an extra layer of protection against leaks and water damage. Although people use them interchangeably, there are subtle differences between them.
Keep reading to learn how roof decking differs from sheathing.
What Is Roof Decking?
Decking forms the foundation on which a roofing system is built. Roofers secure this material to your home’s stresses or rafters. It provides structural support to shingles, tiles or metal panels. This component also helps distribute weight evenly across your roof.
Plywood and oriented strand board (OSB) are two of the most commonly used materials for roof decking. Both options have advantages. While plywood is known for its strength and durability, OSB comes at a more cost-effective price point.
What Is the Role of Roof Sheathing?
The term “sheathing” specifically pertains to boards that cover rafters and trusses. It is usually made of wood and serves as a base for the underlayment and roofing material. Keeping the sheathing in good condition is crucial to preventing leaks and water damage inside your home.
How Are They Different?
The primary function of the decking and sheathing is to serve as the structural base for the roof. In all essence, all sheathing can be considered decking. However, not all decking is referred to as sheathing. Understanding these terms can facilitate better communication with your contractor. It can also help you make more informed decisions about your roofing system.
