In the world of roofing, understanding the basic components of your roofing structure is crucial. An often confusing aspect for many homeowners is distinguishing between roof decking and sheathing. Although they essentially serve similar purposes as foundational layers for your roof, there are distinct differences in their characteristics, applications, and importance for your home’s protection and durability. Tango & Gatti, a locally trusted contractor, shares more insight.
Roof decking, also commonly referred to as roof sheathing, is the layer of materials that sits between the structural components of your roof (such as trusses and joists) and the insulating layers and shingles. It’s a critical part of your roof’s structure, as it provides a flat surface upon which all other roofing materials and structural support are installed. The choice of decking material can greatly affect your home’s ability to withstand heavy snows and high winds.
Typically, roof decking is made from wood (plywood or oriented strand board (OSB) are common choices), though on commercial buildings, it can also be made from metal or concrete. The choice of material often depends on the roofing contractor’s preferences, the specifics of the project, and local building codes. Tango & Gatti always ensures that the most appropriate materials are selected for both performance and compliance with local regulations.
Sheathing, in the context of roof construction, refers explicitly to the panels of material that are laid over rafters or trusses to form the roof base. For all intents and purposes, in many discussions, the terms sheathing and decking are used interchangeably, since they describe the same process and function. However, the term sheathing is more often used to describe the application of these panels to the exterior walls of a structure, providing a layer for the attachment of siding materials.
In roofing, sheathing functions as the layer that gathers and distributes loads from the roof coverings evenly across the roof structure. For homeowners, the quality of sheathing installation by professionals directly correlates with the roof’s ability to handle the weight of heavy snowfall and resist damage from storms.
While the terms roof decking and sheathing might be used interchangeably by some, it’s crucial to understand the nuances in their application and material choice. Roof decking strictly refers to the base layer of the roof, while sheathing can apply to both the roof and the exterior walls. The material for decking or sheathing needs to be carefully selected based on the local climate, the roof’s structural requirements, and the type of roofing materials to be installed.
The structural integrity of your home, particularly in areas susceptible to extreme weather, largely relies on the quality of its construction materials and methods. Properly installed and well-maintained roof decking and sheathing are fundamental to ensuring your home remains safe, insulated, and protected against the elements.
