Sep 20, 2019


When it comes to selecting the right roofing material for your roof, it can be overwhelming to choose between plywood and OSB (oriented strand board). At Bio-One Atlanta, we understand the importance of making informed decisions, especially when it comes to protecting your property. In this comprehensive guide, we will explore the differences between plywood and OSB, helping you determine the best option for your roof.

The Benefits of Plywood

Plywood has been a popular choice for roofing applications for many years. Its durability and strength make it a reliable choice for both residential and commercial properties. Some notable benefits of using plywood for your roof include:

  • Strength: Plywood is known for its superior strength compared to other materials. It can withstand heavy loads, making it ideal for areas with heavy snowfall or high wind speeds.
  • Moisture Resistance: Properly sealed plywood is highly resistant to moisture, which is crucial in preventing mold and rot from developing in your roof.
  • Ease of Installation: Plywood is relatively easy to install, providing a smooth surface for shingle or other roofing material application.
  • Longevity: Plywood has a longer lifespan compared to some alternative materials, ensuring the longevity of your roof.

The Advantages of OSB

While plywood has been a go-to choice for many, OSB has gained popularity in recent years. It offers unique advantages that make it a suitable option for certain roofing projects. Here are some key advantages of using OSB for your roof:

  • Cost-effectiveness: OSB is often more affordable than plywood, making it an attractive option for budget-conscious individuals.
  • Environmental-Friendly: OSB is typically made from fast-growing trees, which makes it a sustainable and renewable option for eco-conscious homeowners.
  • Consistent Strength: Over the years, OSB has improved in terms of strength and consistency, making it a reliable choice for roofing applications.

Choosing the Right Material

When it comes to selecting the best roofing material for your roof, there are several factors to consider. Here are some key points to help you make an informed decision:

  • Climate: Assess the climate in your region. If you live in an area prone to heavy rain, snow, or high winds, plywood's superior strength may be the better choice. However, if climate conditions are mild, OSB may be a viable and cost-effective option.
  • Budget: Consider your budgetary constraints. Plywood tends to be more expensive than OSB, so assess your financial capacity before making a final decision.
  • Intended Use: Determine how you plan to use your roof. If you intend to create additional outdoor living spaces or install heavy equipment on your roof, plywood's strength may be more suitable. If your roof will primarily serve as a protective barrier, OSB may meet your needs.


Ultimately, the choice between plywood and OSB for your roof depends on various factors, including climate, budget, and intended use. Bio-One Atlanta, with our expertise in the business and consumer services - cleaning industry, recommends assessing your specific needs and consulting with a roofing professional before making a final decision. Whether you choose plywood or OSB, both materials have their own advantages and can provide reliable protection for your property.
