CDX Plywood for Roof Sheathing
CDX plywood is a popular choice for roof sheathing due to its strength and durability. The layers of wood are bonded together, with alternating wood grain patterns to enhance strength. The grades of the front and back surfaces play a crucial role in determining the quality of the plywood sheet.
CDX plywood is classified by the letters C and D, representing the grades of the surfaces. A-grade plywood is the highest quality and is typically reserved for applications where the appearance of the plywood is important. However, for roof sheathing, C-grade plywood is acceptable. It provides sufficient strength and durability while offering significant cost savings.
The letter X represents the type of glue used to bond the layers of plywood together. In the case of CDX plywood, exterior-grade glue is used, ensuring the plywood can withstand temporary exposure to rain and moisture without compromising its structural integrity. This moisture resistance makes CDX plywood reliable and well-suited for roof sheathing.
CDX plywood strikes a balance between affordability and functionality, making it an ideal choice for roof construction. Its strength, durability, and moisture resistance make it a reliable option for withstanding the elements. Whether you’re a professional roofer or a homeowner embarking on a DIY roofing project, CDX plywood offers peace of mind and long-lasting performance.
When it comes to selecting the best plywood for roof sheathing, CDX plywood proves to be a top choice. Its strength, durability, and moisture resistance make it a reliable option for protecting your roof. At Lynchburg Roofers, we recommend CDX plywood for all your roof sheathing needs.

Plywood Thickness for Roof Sheathing
The proper plywood thickness for roof sheathing is a crucial consideration to ensure the structural integrity and longevity of your roof. The thickness of plywood required depends on several factors, including rafter spacing, roof loads, and slope.
Rafter spacing: Traditionally, half-inch CDX plywood was commonly used for roofs with 24-inch rafter spacing. This thickness provided sufficient support for standard roof loads. However, for roofs with heavier loads or less pitch, a thicker plywood may be necessary.
Roof loads: The weight of the roofing materials, such as asphalt shingles or metal panels, along with any additional load-bearing requirements, must be taken into account when determining the plywood thickness. A higher load may require thicker plywood to prevent sagging and ensure proper support.
Slope: The slope of the roof also influences the plywood thickness needed. For low-slope roofs or roofs with a slope less than 4:12, a thicker plywood is recommended to provide additional support and prevent water pooling.
Here are some general guidelines for plywood thickness based on common roofing types:
| Roofing Type | Recommended Plywood Thickness |
|---|---|
| Standard Asphalt Shingle | 5/8 inches |
| Metal Roof or Low-Slope | 3/4 inches |
It’s important to consult with roofing professionals or refer to manufacturer specifications to determine the appropriate plywood thickness for your specific roofing needs. They can provide expert advice based on your roof design, local building codes, and environmental factors.

OSB vs. Plywood for Roof Sheathing
When it comes to selecting the right material for roof sheathing, the choice often comes down to OSB (oriented strand board) and plywood. Understanding the differences and weighing the pros and cons of each option is crucial for making an informed decision.
OSB is made from compressed wood strands that are bonded together. It offers several advantages, including cost-effectiveness, excellent moisture resistance, and ease of installation. Its interlocking strands provide strength and durability, making it suitable for roof sheathing. However, OSB does have some limitations. When wet, it takes longer to dry compared to plywood, which can prolong construction timelines. Additionally, OSB may have swollen edges that can potentially show through shingles, affecting the aesthetic appeal of the roof.
On the other hand, plywood is constructed from thin wood veneers glued together in layers. Its cross-grain configuration gives it exceptional strength and stability, making it a preferred choice for larger or steep-slope roofs. Plywood also generally offers better moisture resistance compared to OSB. However, it is typically more expensive than OSB and may require additional maintenance to protect against water damage.
When deciding between OSB and plywood for roof sheathing, it’s important to consider your specific roofing needs and the climate in your area. OSB is a suitable option for cost-conscious projects that require good moisture resistance. Plywood, on the other hand, is preferable for applications that demand superior strength and stability. Consulting with roofing professionals, such as Lynchburg Roofers at 434-555-0164, can provide valuable guidance to help you make the right choice for your roof.
Comparison Table: OSB vs. Plywood for Roof Sheathing
| OSB | Plywood | |
|---|---|---|
| Material Composition | Made from compressed wood strands bonded together | Constructed from thin wood veneers glued in layers |
| Cost-effectiveness | Generally more affordable | Usually more expensive |
| Moisture Resistance | Offers good moisture resistance | Generally provides better moisture resistance |
| Strength and Stability | Provides adequate strength and stability for most applications | Offers superior strength and stability, suitable for larger or steep-slope roofs |
| Installation | Easy to install | Slightly more complex installation process |
As shown in the comparison table, both OSB and plywood have their own distinct advantages and considerations. By carefully evaluating the needs of your roof and considering factors such as cost, moisture resistance, strength, and stability, you can make an informed decision between OSB and plywood for your roof sheathing.

Special Considerations for Roofing Plywood
When it comes to choosing the right plywood for your roofing project, there are a few specialized options to consider. In addition to the commonly used CDX plywood and OSB, there are other types of plywood that offer unique benefits.
One such option is ZIP wood, an engineered product that is specifically designed for roofing applications. ZIP wood is known for its exceptional strength and durability, making it an excellent choice for areas with high winds or heavy snow loads. What sets ZIP wood apart is its built-in water-resistant barrier, which eliminates the need for additional roofing felt. This not only saves on installation time and costs but also provides added protection against moisture intrusion. Furthermore, ZIP wood offers energy efficiency benefits due to its continuous insulation properties, helping to reduce heating and cooling costs.
Another consideration is fire-retardant (FRT) plywood. While not always required, FRT plywood may be necessary in certain cases, especially for structures where fire spread is a concern. FRT plywood undergoes a process of acid hydrolysis when exposed to fire, which increases its fire resistance and helps prevent the spread of flames. It is important to check local building codes and consult with roofing professionals to determine if FRT plywood is necessary for your specific project.
