Choosing the Best Roof Decking: Factors to Consider for Your Project

Roof decking is an essential component of any roofing system. It is the layer of material that sits on top of the roof structure and provides a flat surface for the roofing materials to be installed. The type of decking used can have a significant impact on the performance and lifespan of the roof, so it's essential to choose the right material for the job.

In this blog, we'll take a closer look at roof decking, including what it is, the different types available, and some tips for selecting the best option for your roofing project.

What is Roof Decking?

Roof decking is the layer of material that sits on top of the roof structure and provides a flat surface for the roofing materials to be installed. It's typically made from wood, metal, or concrete, and serves as the foundation for the roofing system.

The type of decking used will depend on a variety of factors, including the climate, building codes, and the type of roofing material being used. For example, if the roofing material is heavy, such as clay tiles, a more robust decking material will be required to support the weight.

Types of Roof Decking

There are several types of roof decking available, each with its unique characteristics and advantages. Let's take a look at some of the most common options.

Plywood Decking

Plywood is a popular option for roof decking due to its affordability and versatility. It's made from thin layers of wood veneer that are glued together to create a strong and durable material.

Plywood decking is available in various thicknesses, and the thicker the material, the more weight it can support. It's also easy to cut and shape, making it an excellent option for irregularly shaped roofs.

OSB Decking

Oriented Strand Board (OSB) is another popular option for roof decking. It's made from wood chips that are glued together under high pressure and heat, creating a strong and durable material.

OSB decking is less expensive than plywood and is more environmentally friendly since it's made from wood chips rather than whole trees. However, it's not as strong as plywood and can be prone to swelling and warping when exposed to moisture.

Concrete Decking

Concrete decking is a durable and long-lasting option that's typically used in commercial and industrial buildings. It's made from a mixture of cement, sand, and water, and is poured into place to create a solid surface.

Concrete decking is incredibly strong and can support heavy roofing materials. However, it's also heavy and can add significant weight to the roof structure, so it's not suitable for all types of buildings.

Metal Decking

Metal decking is typically made from steel or aluminum and is a popular option for flat roofs. It's lightweight and easy to install, making it an excellent option for large commercial buildings.

Metal decking is also incredibly durable and can withstand harsh weather conditions, making it a good choice for buildings in areas prone to hurricanes or strong winds. However, it's more expensive than other decking materials and can be prone to rust if not properly maintained.

Selecting the Right Roof Decking

Consider the Climate

The climate in your area will play a significant role in the type of decking you choose. If you live in an area with high humidity or frequent rain, you'll want to choose a decking material that's resistant to moisture, such as plywood or metal.

Choose the Right Thickness

The thickness of the decking material will depend on the weight of the roofing material and the building codes in your area. Be sure to consult with a roofing professional to determine the appropriate thickness for your project.

Check Building Codes

Building codes will dictate the type of decking material that's allowed in your area. Be sure to check with your local building department to ensure that the material you choose meets the required standards.

Consider Longevity

The longevity of the decking material is also an important factor to consider. While some materials may be less expensive upfront, they may not last as long as other options. Consider the lifespan of the material and the potential cost savings over time.

Think About Sustainability

If sustainability is a priority, consider using environmentally friendly decking materials, such as OSB or metal. These materials are made from recycled materials and are more sustainable than traditional options like plywood.
