types of roof decking

Roofing

The answer to 'types of roof decking' is that there are several common materials used for roof decking, including plywood, oriented strand board (OSB), and dimensional lumber. Plywood and OSB are the most popular choices, as they provide a sturdy, stable surface for the roofing materials. Dimensional lumber, such as 2x4s or 2x6s, can also be used, but is less common in modern construction.

Plywood and OSB are both engineered wood products that are made by layering thin wood veneers or strands, respectively, and bonding them together with adhesives. These materials are durable, weather-resistant, and provide a smooth, even surface for the roof. They are also relatively lightweight, making them easy to work with during installation.
