Roof decking may be out of sight, but this is also why you should pay closer attention to it. It’s a critical part of your roofing system as it is attached to the trusses and joints, which are essentially the basic framework of your roof. Any problem in your roof decking can have serious consequences to the integrity of your roofing.

Benefits of Roof Decking
The main role of roof decking is to support the roof shingles and keep them secure. This part of the roofing system also provides a layer of protection against severe weather and fire.
Roofing contractors, however, have an exception for plywood decking because it does not have a full capacity for fire resistance. If you have plywood decking, you might want to consider spraying on flame retardants on its surface for an extra layer of defense.
Additionally, keep in mind that your roof decking is also essential to leak prevention. It can reduce risks for roof damage and help make your roof last for many years.
Types of Roof Decking
Roof decking comes in different materials and designs. That said, it’s best to have a good understanding of these options to ensure the best choice for your home.
OSB Sheathing – OSB, or oriented strand board, is designed with interweaving wood strands that are bonded together. This is widely considered as the most popular type of roof decking.
Tongue and Groove – This type of roof decking is mostly used in homes without ceiling. Its design consists of 2 x 6 boards with a “tongue” on one edge, and this is fitted into a “groove” on the edge of another board.
Plywood Sheathing – For plywood sheathing to be rigid and moisture-resistant, experts recommend that it should be made from mature trees.
