Plywood Decking

If you’re looking for a cost-effective and durable option for roof decking, plywood is a popular choice.

Plywood decking offers several advantages that make it a practical option for your roof. Firstly, it’s known for its strength and durability, capable of withstanding heavy loads and extreme weather conditions.

Secondly, plywood is easy to install and provides a smooth and even surface for other roofing materials to be applied on.

When installing plywood decking, it’s important to ensure that the panels are properly aligned and securely fastened to prevent any water leakage or structural issues.

Additionally, using a waterproofing membrane beneath the plywood can offer added protection against moisture.

Regular maintenance, such as sealing the edges and applying a protective coating, can extend the lifespan of your plywood decking.

Overall, plywood decking is a reliable and cost-effective choice for your roof.

OSB Decking

You should consider using OSB decking for your roof.

OSB, or oriented strand board, is a popular choice for roof decking due to its many advantages.

Advantages of OSB decking:

  • Cost-effective: OSB is generally more affordable than plywood, making it a budget-friendly option for your roof.
  • Durability: OSB is known for its strength and resistance to warping or splitting, ensuring a long-lasting roof deck.
  • Moisture resistance: OSB is treated to resist moisture, preventing damage from leaks or condensation.
  • Easy installation: OSB is lightweight and easy to work with, making the installation process quick and efficient.

Installation process of OSB decking:

  1. Measure and cut the OSB panels to fit the roof dimensions.
  2. Lay the panels perpendicular to the roof joists, staggering the seams for added strength.
  3. Secure the panels to the joists using nails or screws.
  4. Repeat the process until the entire roof is covered with OSB decking.

Metal Decking

Metal decking offers a strong and reliable alternative for your roof. There are several advantages to choosing metal decking for your roof.

Firstly, it’s incredibly durable and can withstand harsh weather conditions, such as strong winds and heavy snowfall. Metal decking is also fire-resistant, providing an added layer of safety to your home.

Additionally, metal decking is lightweight, making it easier to install and reducing the load on your roof structure. There are different types of metal decking available, including steel and aluminum.

Steel decking is known for its strength and longevity, while aluminum decking is lighter and resistant to corrosion. Both options offer excellent durability and can be customized to fit your specific roofing needs.

Consider metal decking for a reliable and long-lasting roof solution.

Composite Decking

Composite decking is a durable and low-maintenance alternative for your outdoor flooring needs. It’s made from a combination of wood fibers and recycled plastic, providing a strong and long-lasting surface that requires minimal upkeep. Here are some advantages and disadvantages of composite decking:


  • Resistant to rot, mold, and insects, making it ideal for outdoor use.
  • Doesn’t require staining or sealing, saving you time and money.
  • Available in a wide range of colors and styles, giving you plenty of design options.
  • Eco-friendly option, as it utilizes recycled materials.


  • Can be more expensive upfront compared to other decking materials.
  • May fade or discolor over time, especially in direct sunlight.
  • Some composite decking can be prone to scratching.

Installation Process:

  • Composite decking is installed similarly to traditional wood decking, using screws or hidden fasteners.
  • It’s important to follow the manufacturer’s guidelines for proper installation.


  • Regular cleaning with a mild detergent and water is usually sufficient.
  • Avoid using abrasive cleaners or pressure washers, as they can damage the surface.

Enjoy the benefits of composite decking and transform your outdoor space into a beautiful and low-maintenance oasis.

Concrete Decking

Concrete decking offers a durable and long-lasting solution for your outdoor flooring needs. It’s known for its strength and ability to withstand heavy loads, making it a popular choice for patios, driveways, and pool decks.

One of the advantages of concrete decking is its versatility. It can be customized with various finishes, colors, and patterns to match your aesthetic preferences. Additionally, concrete decking requires minimal maintenance, as it’s resistant to rot, decay, and pests.

However, there are also disadvantages to consider. Concrete can crack over time, especially in areas with freeze-thaw cycles. It can also become slippery when wet, posing a safety hazard.

To install concrete decking properly, it’s important to prepare the site, pour the concrete evenly, and allow it to cure before use. Regular sealing can help prevent cracking and prolong its lifespan.
