April 2, 2022

Choosing the right roof sheathing for your home is crucial to ensure its durability, strength, and longevity. Roof sheathing is the foundation of your roof system and plays an important role in protecting your home from harsh weather conditions. A good roof sheathing also distributes the weight of your roof evenly, preventing any potential damages. However, selecting the right type of sheathing can be challenging, as there are various materials, sizes, and installation methods to consider. In this article, we will discuss some of the essential factors that you need to consider when selecting the right roof sheathing for your home.


When it comes to selecting the right roof sheathing for your home, the type of material you choose is vital. There are various types of sheathing materials available in the market, including plywood, OSB (Oriented Strand Board), and wood fiberboard. Plywood is the most commonly used sheathing material in home construction, and for a good reason. It is sturdy, durable, and moisture-resistant, making it a great option for areas with high humidity levels. OSB, on the other hand, is an affordable and lightweight material that is easy to install. However, it is not as strong as plywood and may not be suitable for high wind areas. Lastly, wood fiberboard is an eco-friendly and sustainable option that is made from wood products and is ideal for insulation.


The size of your roof sheathing is another critical factor that you need to consider. Roof sheathing comes in various thicknesses and sizes, and the size you choose depends on the pitch of your roof. If your roof has a low pitch, you will need thicker sheathing to provide more support. Alternatively, if your roof has a steep pitch, you may need thinner sheathing as the pitch will provide more support. Your roof framing materials will also dictate the size of your sheathing, and it’s essential to consult a professional roofer to help you make the right choice.

Weather Resistance

When selecting your roof sheathing, it’s important to consider the weather conditions in your area. If you live in an area with high wind and heavy rainfall, you will need a sheathing material that is strong and moisture-resistant. Areas with high humidity levels will require a sheathing material that is mold and mildew-resistant. Additionally, if you live in an area that experiences extreme Roof sheathing weather conditions like tornadoes or hurricanes, you may need to consider specialty sheathing that is designed to withstand such conditions.

Installation Method

Roof sheathing can be installed using either the nailed method or the screwed method. The nailed method involves attaching the sheathing to the roof framing using nails, while the screwed method involves using screws to secure the sheathing to the framing. Both methods have their advantages and disadvantages, and the one you choose depends on various factors like the size of your roof and the material you choose. It’s important to consult a professional roofer when selecting the right installation method for your sheathing.


Selecting the right roof sheathing is essential to ensure the durability and longevity of your roof. When selecting your sheathing, consider factors like material, size, weather resistance, and installation method. It’s important to work with a professional roofer to help you make the right choice and ensure proper installation. Remember that the roof sheathing is the foundation of your roof system, and investing in quality material and installation can save you from costly repairs and replacements in the long run.
