What Material Should I Use for My Rooftop Decking?

There are different types of decking materials in Ultradecking you can use to build a deck on your rooftop. You can use the same decking material as a ground deck to also build a roof deck. Examples of flooring materials are wood or timber decking, composite decking and PVC decking materials.

These types of materials are the most common decking materials available in the market. When you consider each of these materials, you’ll be able to choose the best type of material to use in building a rooftop deck.

Composite Decking 

Composite decking is regarded as the best decking material to use in building a deck. This is because composite decking is solid and durable and has a long life span. Composite decking is a material that you will like if you use it to build a deck on your roof.

The engineers made composite decking with a mixture of wood and plastic material, making it superior to wood and plastic decking. The composite decking material is so strong that it is highly resistant to termites and other wood-eating insects.

Besides that, composite decking is also resistant to water. The composite board has a plastic film on its surface that prevents water from penetrating the material. If rain should fall on your roof, decking the composite board will not absorb water.

Additionally, composite decking is a good option because its colour does not fade. The decking has UV ray protection on its outer layer that prevents the board colour from fading. Composite decking will not require painting or staining like wood.

It is a decking material that homeowners valued for its aesthetics. A composite board can last for a long time and still stay beautiful.

Wood and Timber Decking 

Timber decking is a traditional decking material you can install on the ground and rooftop of your home. You can use either treated wood, cedar, redwood or ipe for wood decking. Wood decking is a cheaper decking option with less value compared to the composite board.

In terms of aesthetics, timber decking does not equate to composite decking. The colour of the wood fades on exposure to ultraviolet rays. To maintain the look of timber, you will need to apply stains on it. Also, when it comes to choosing a material for your rooftop decking, wood isn’t the best option.

Wood decking can warp, break or splinter over years of use. It is also not resistant to weather conditions. The timber decking will absorb moisture and swell when humidity is high. They are also not resistant to water. Timber decking will require sealing to make it water-resistant. Apart from that, timber decking is also susceptible to termite damage.

Maintaining wood decking is stressful and will require a lot of cash, as you will have to stain or paint your rooftop decking annually. You will also need to waterproof a timber decking to prevent it from absorbing water or moisture.

 Plastic Decking

Plastic decking contains 100% plastic making it a waterproof decking material. They are the most expensive type of decking material you can use for ground and rooftop decking. Plastic is also resistant to rot, like composite decking material. It is also durable and will not warp, crack or splinter like wood. Plastic decking has similar features to composite decking, but the latter has a longer lifespan than plastic.

PVC is a good decking material you can use for rooftop decking. Using plastic is less stressful and also easier to maintain, like composite decking. You don’t have to worry about applying paint or stain, seal or sand to the surface of your plastic decking.


The material to be used for rooftop decking should be durable. Of all the materials mentioned in this write-up, composite decking is the best option. It is durable and easy to maintain. Composite decking also has an extended lifespan compared to wood and plastic decking.
