Materials Required for Roof Deck Flooring

The materials are different. You have many alternatives when creating a roof deck, and it’s up to you which one you select. The choice should be affected by elements, including the material’s cost and accessibility in your location.

Now we will briefly tell you about each type of material that can be used in deck roof flooring.


Porcelain stoneware pavers made of porcelain stoneware are one of the frequently chosen types of flooring. They are made of high-quality clay and fired at high temperatures, which makes them highly resistant to various damages. It also perfectly imitates the appearance of wood or concrete due to its characteristics.

Concrete pavers are comprised of cement and aggregate and may be customized to match the structure’s architectural design or the natural environment. Due to their weather resistance and ability to tolerate wind, rain, and sunlight exposure, both pavers are appropriate for roof decking. They are perfect for outdoor locations since they are also simple to care for.


Wood is an ageless classic that has always been relevant for roof deck flooring. Deck tiles made of this material look natural and beautiful. Various species can be used for rooftop deck flooring; cedar is especially popular. Of course, decking wood for rooftop deck flooring is not completely natural in the usual sense of the word. It is pretreated with different types of chemicals. This prevents the wood from rotting or attacking insects, which greatly increases the life of the material. A trendy option for roof deck flooring is pressure-treated wood.

As an advantage of wood, it is possible to note a natural look and beauty. Such material is universal; it can be painted in any color and repainted over time in another. Timber is also considered one of the most affordable options for a renovation budget.

Nevertheless, wood must often be maintained with chemicals, painted, or sealed. You also need to consider waterproof membranes, as wood flooring can warp, crack, or rot over time if not properly cared for.


Composite decking is a hybrid of wood and plastic. Even though, in appearance, it very much resembles a tree, it is not quite one. The composite is quite affordable, and its use makes repairs quite budgetary.

It is worth noting that the advantage is that composite flooring does not require any special care, as is the case with wood. All that is required is to clean it from contamination periodically. At the same time, it is resistant to decay, insects, and all weather conditions.

However, composite decking will typically cost a bit more than wood. It is also important to protect it from the sun because it heats up quickly, leading to overheating the entire structure.

Polyvinyl Chloride

Unlike wood or composite, PVC flooring is made from 100% plastic. It is extremely durable, affordable, and easy to install. You can get it anywhere and anytime, as PVC is a fairly popular solution among builders.

People love PVC for its low maintenance, as it requires little to no maintenance other than occasional cleaning. It doesn’t deteriorate at all over time. However, many may argue that PVC flooring is much more expensive than other deck materials, and there is some truth to this.

As a disadvantage, it can be noted that PVC can heat up under the sun, thus reducing its service life.


The most popular material is aluminum. Aluminum flooring is a revolutionary material that differs from others in absolute strength and low problems. The most striking advantages are durability, lack of maintenance, and weight.

Aluminum decking is virtually maintenance-free except for occasional cleaning; it is completely resistant to rot, insects, and weather and very light and easy to install.

However, aluminum is considered the most expensive flooring material. It also corrodes when misused and gets very hot at high outside temperatures.
