Understanding the various components that make up your roof is essential for making informed decisions about its construction and repair. Two terms that often cause confusion are roof decking and sheathing. While they are often used interchangeably, these two elements play distinct roles in the architecture of a roof.
In this article, Royal Roofing Construction distinguishes these components from each other to help you communicate better with your roofer.
Roof Decking
Roof decking is the layer of materials that forms the base of your roofing system. This foundation lies between the structural components of the roof (the trusses and joists) and the waterproofing layers (such as shingles or metal roofing). Plywood and oriented strand board (OSB) are the most commonly used roof decking materials. They are selected for their durability, strength, and resilience against various climate conditions.
The primary purpose of roof decking is to provide a strong, flat surface upon which the outer roofing materials can be installed. Additionally, roof decking contributes to the structural integrity of the entire roofing system, distributing weight evenly across the roof frame and supporting the layers that keep water and weather out of your home. If your area experiences occasional heavy rains and winds, having sturdy decking is indispensable for the longevity of your roof.
Roof Sheathing
Sheathing refers to the panels used on the roof decking, which can extend to the sides of the house, underneath the siding. Selecting the right material for your roof sheathing is crucial. Plywood offers better resistance to moisture damage, while OSB is typically more cost-effective. The choice often depends on your roof design, budget, and environmental factors. Consulting roofing experts like Royal Roofing Construction can help you determine the best material for your project.
Roof Decking and Sheathing Maintenance
Maintenance of your roof’s decking and sheathing is essential to prolong the life of your roof. Regular inspections can detect issues such as rot, mold, or structural damage before they compromise the integrity of your roofing system. In regions where the climate can fluctuate significantly, this preventive measure is even more critical.
