What Is Composite Roof Decking?


Roof decking is available in a variety of different materials to fit the needs of specific applications. Each option has its own advantages and disadvantages. Composite roof decking is a popular option that offers high durability and low maintenance. Let’s take a closer look at what composite roof decking is and how it performs to see if it’s the right material for your project.

What Makes Composite Roof Decking Different?

Composite material is a material made from two or more components that have different properties that, when combined, create a new material that is superior to the separate components.

Composite pavers are a blend of recycled materials, including plastics and rubber, and polymers that bind together to create an incredibly strong, durable, and recyclable material. Composite roof decking can also be manufactured in a variety of colors to complement the design aesthetic.

Does Composite Roof Decking Lay Flat?

Composite roof decking lays flat on the roof, but the roof will slope slightly to facilitate drainage during rain. In contrast, a pedestal roof deck system floats above the roof, to create a perfectly level surface. Pedestal systems are expensive and heavy and have a complicated installation process. If the actual surface of the roof is uneven with high and low spots or undulations, shims can be used to level out composite decking.

Composite Roof Decking Alternatives

Composite roof decking offers a range of benefits, but other materials have their own advantages and disadvantages as well. Other materials include:


Wood roof decking creates a beautiful aesthetic, but it requires sustained maintenance over the course of its life and is prone to warping over time. It should also be refinished, whether painted or stained, periodically, in order to maintain its appearance and remove any chipped or flaked paint.


Porcelain roof decking creates an upscale look and is best for spaces where the aesthetic takes precedent. It is shiny and slippery, so it can be dangerous for rooftops, especially after rain or when it’s wet with dew in the morning.


Concrete is a common roof decking material, and it is known for being durable and long-lasting as well as providing an industrial look. However, concrete can stain, so it isn’t best in areas where food or drink may be spilled. It is also prone to cracking on impact, and its weight can mean additional structural support is needed to support the pavers.
