CDX vs. OSB for roof replacement: Which is the best choice for your roof?

When it’s time to replace your roof, one of the most crucial decisions is selecting the right materials to ensure durability and long-term performance. Two of the most common options for roof decking are CDX plywood and OSB (Oriented Strand Board). While OSB may seem attractive due to its lower cost, CDX consistently proves to be the better choice for long-term durability, especially in regions with harsh weather conditions,

In this blog, we’ll break down the key differences between CDX and OSB to help you make an informed decision.

What is CDX?

CDX is a type of plywood made by gluing layers of wood together, with the grain of each layer oriented in different directions. It is known for its excellent resistance to moisture, making it a reliable choice for roof decking in areas with variable weather conditions like Avon.

Advantages of CDX:

• Superior structural strength: CDX’s cross-layer construction gives it greater strength, making it perfect for roofs that need to bear heavy loads such as snow, hail, or ice. In regions like Avon, where winters can be tough, this added strength is critical to maintaining a sturdy roof.
• Moisture resistance: While no material is completely waterproof, CDX has better moisture resistance than OSB. This makes it a safer option for roof decks exposed to the elements before shingles are installed, and reduces the risk of warping or degradation over time.

What is OSB?

OSB is a manufactured material made by compressing layers of wood strands bonded with resin into a rigid panel. It’s typically less expensive than CDX, which makes it a popular choice for homeowners looking to lower the cost of their roof replacement.

Advantages of OSB:

• Lower cost: OSB is generally more affordable than CDX, which can help reduce the initial costs of your roof replacement project. However, this cost savings can come at the expense of performance, particularly in areas with demanding weather conditions.
• Uniform construction: Unlike plywood, OSB is more uniform in its construction, allowing for more predictable and consistent installation.

Choosing between CDX and OSB depends on several factors, including your budget and the climate conditions in Avon, Massachusetts.
