When most people think of roofs, they usually think of the shingles. But shingles are just the surface, and a roof has far more going on below them. Shingles provide external protection from sun, rain, wind, and other weather, but underneath those shingles is where you’ll find the roof decking. That’s where the true strength and stability of the roof lies. Polaris Roofing Systems can help with any of your roofing problems.

Roof Decking Explained Simply

You might be confused when a roofer refers to roof decking, but it’s really quite simple. The roof’s foundation consists of a series of beams and trusses that ultimately determine the shape of the roof. Because there are large gaps between these structural elements, it’s not only difficult to move around on the roof; it’s also complicated to attach the shingles that help protect the roof from the elements. Enter roof decking.

Roof decking, which also goes by the name roof sheathing, is a layer of material that’s attached to the roof beams and joists to make it easier to move about on the roof while also providing greater protection for the home and a stable and secure base for attaching the shingles themselves.

What is Roof Decking Made Of?

Several materials are used for roof decking. The choice of which is best for a particular job depends on how much support is needed for the shingles or other things that might add weight to the roof, such as air conditioning units or solar panels.

The most cost-effective material for roof decking, and one of the most popular, is oriented strand board (OSB). OSB is a type of particleboard made by compressing wood strands with an adhesive to create large panels. It’s strong, lightweight, and inexpensive.

Another popular option for roof decking is plywood. Usually, pressure-treated plywood is used in roof decking applications because it is common for moisture to accumulate under the shingles, which could lead to rotting. Pressure-treated plywood mitigates this problem. Plywood is also relatively inexpensive and can be as thick as five inches where more support is needed.

Other materials that are used for roof decking include concrete and steel. Concrete is becoming increasingly popular because it seals well and can handle heavy loads. Steel is exceptionally lightweight and incredibly durable. It also reflects heat extremely well, making it an excellent choice for Flagstaff area homes. Its only downside is its high cost.

Don’t Neglect Your Roof Decking

If you have shingle damage and are thinking of simply replacing the damaged shingles, you might want to think again. Such damage can extend to your roof decking as well, which will create far more significant problems in the long run. Once your decking is compromised, you’ll likely start to see signs of water damage appear in your house. That can be much more expensive than a roof repair.

Even when the decking doesn’t need replacement, it can be a good move to do so before any damage is done to your roof. New decking improves your roof’s structural integrity and gives you an opportunity to upgrade to a more beneficial decking material.
