When it comes to residential roofing, we often give importance to the roof covering, from asphalt shingles to clay tiles. Rarely do we mention one of the most essential components of this complex system—the roof decking. It is the layer of wood that lays flat on the empty spaces in between the roof’s trusses and joists, providing a surface for the weatherproof materials like the underlayment and roof covering to attach to.
Coxco Roofing, one of the top roofing contractors in the area, shares the things you might not know about roof decking.
1. Decking can be called sheathing.
If you see the term “sheathing” in the context of roofing, it’s the same thing as decking. Depending on which roofer you talk to, they’ll use either one of the two terms to refer to the same part of your residential roofing system.
2. The decking’s thickness varies depending on the roof’s slope.
A steep roof slope requires thinner decking. It doesn’t need the support of a thicker decking since the steepness of the roof allows rainwater to run down the gutters. A flat roof, however, needs strong and durable sheathing so that it can hold the weight of standing water. In both instances, the decking must have the right thickness to support a roofer walking on it during roof replacement or any type of roof work. It should also comply with the housing regulations set forth by the neighborhood or city.
3. Roof decking comes in different types.
Plank sheathing was first used to cover the roof’s rafters. Today, residential roofing systems either have the plywood or oriented strand board (OSB) sheathing. Plywood decking is composed of thin sheets of veneer glued together to make it rigid and moisture-resistant. OSB sheathing, meanwhile, is created by interweaving wood strands bonded together through thermal pressing.
