The Best Materials for Rooftop Decking

A rooftop deck is an ideal way to enjoy your outdoor space while taking in a view of the surrounding area. But before you can start hosting cookouts and relaxing, there’s one key decision you have to make – which material should be used for your rooftop deck?

Depending on the environmental conditions, cost considerations, and aesthetic appeal, choosing the right decking material can become quite a challenge.

To help guide your choice, we take an in-depth look at the best rooftop decking options, such as composite decking, and the different factors to bear in mind.


Why install rooftop decking?

Rooftop decking is a great way to get more use and enjoyment out of your rooftop space. With the right materials, you can create a comfortable outdoor oasis that provides ample room for entertaining, lounging, or dining alfresco. In addition, installing a rooftop deck can add value to your property, making it an appealing investment.


Materials for rooftop decking: wood and composite

The two most popular materials for rooftop decking are wood and composite. Each of these decking options has its own unique set of features and benefits that make it an ideal choice for a rooftop deck:

Wood decking

Wood is the traditional material used in outdoor decks, as it provides excellent durability while offering a classic aesthetic appeal. Additionally, wood is affordable and easy to work with, making it a great choice for DIY projects. 

However, wood requires regular maintenance, such as staining and sealing every few years, to ensure that it retains its aesthetic appeal over time.

Composite decking

In recent years, composite materials have become increasingly popular for outdoor decking. Composite is made from a blend of recycled plastic and wood fibres, giving it excellent resistance to water and decay. 

Additionally, composite materials require much less maintenance than traditional wood decking and come in a variety of colours and styles that can be customised to fit any aesthetic. 

However, as composite is more expensive than wood, cost may be a factor when choosing between the two materials.

Other decking options for rooftop decking

In addition to wood and composites, there are also other materials available for outdoor decking. Stone is a great choice due to its natural beauty and durability, while concrete offers an affordable and low-maintenance option. 

Additionally, aluminium decking is also available, although it’s important to keep in mind that this material will require more maintenance than other options.


Factors to consider when choosing a rooftop decking material

When it comes to choosing the best material for your rooftop deck, there are several factors to consider. These include:


  • Cost – Different materials have different price points, so cost can be a major factor in deciding which material is right for you. Composite decking, for instance, is more expensive than wood but requires less maintenance. But it is not as much as most hardwood decks. 
  • Maintenance – Different materials require varying levels of maintenance, so it’s important to consider how much time and effort you’re willing to spend on upkeep. Wood decking, for example, requires regular staining and sealing to maintain its aesthetic appeal.
  • Aesthetic appeal – Different materials offer different looks, so it’s important to choose a material that has an aesthetic that suits your tastes and fits in with the existing design of your home.
  • Durability – Some materials are more durable than others, so it’s important to choose a material that will stand the test of time. Composite decking, for instance, is highly resistant to water and decay. Especially composite capped boards from our Forma and Grande composite decking range. 
  • Sustainability – If you’re looking for a more sustainable option, composite is the way to go as it is made from recycled materials. Composite materials, for instance, are made from recycled plastic and wood fibres, making them a great choice.



How much maintenance is required for rooftop decking?

The amount of maintenance required for rooftop decking will depend on the material that you choose. For example, composites and metal require less maintenance than wood. 

What is the most durable option?

Composite decking is the most durable option due to its excellent resistance to water and decay. However, all materials will require proper maintenance and care in order to maintain their appearance over time.
