Types Of Roof Decking
Types Of Roof Decking
Before you choose your roof decking, you should familiarize yourself with the various types. A professional roofer can ensure the materials you choose suit your roofing project. Several factors will determine the type of roof decking you should have, like whether you are installing a new roof for a commercial or residential space.
Plywood
Based on our experience with previous clients, plywood remains one of the top choices for roof decking. It contains thin layers of wood veneer glued together, creating a strong, durable, lightweight material. You will find high-quality panels with smooth surfaces or low-grade panels with visible knots and imperfections.
Oriented Strand Board
Oriented Strand Board (OSB) proves cost-effective and durable, making it an excellent alternative to plywood roof decking. Manufacturers craft OSB by compressing and bonding strands of wood, creating a powerful, long-lasting panel. The beauty of OSB lies in its versatility-it comes in various thicknesses and grades, allowing for a custom-tailored roof.
Metal
We often install metal roof decking for commercial and industrial buildings with flat or low-slope roofing systems. Clients choose steel or aluminum metal roof decking because of its durability and fire resistance.
