Can Metal Roofing Be Installed Over OSB?

Recent Posts

As a property owner planning a roofing installation project, you might consider using an Oriented Strand Board (OSB) as the substrate. But would installing metal roofing on top of it cause any issues down the line? Let’s dive into this topic and shed some light on your concerns.

OSB And Metal Roofing: A Compatible Duo

Good news! It is indeed possible to install metal roofing over OSB. OSB, a type of engineered wood panel, is lightweight, durable, and highly versatile, making it a popular choice in construction. It often serves as roof decking – the bottom layer on top of the home’s framing.

However, specific factors should be considered when using OSB as the substrate for your metal roofing panels. One of those is the condition of the OSB. It needs to be in good shape as it tends to deteriorate if exposed to moisture, losing fastener pull-out resistance.

How To Install Metal Roofing Over OSB Board

So, how exactly do you prepare the OSB surface before installing metal roofing? Here’s a quick guide:

  1. Inspect the OSB: Ensure it’s in good condition, with no signs of moisture damage.
  2. Prepare the surface: Clean the OSB roofing to remove any debris.
  3. Install an underlayment: This provides extra protection against water and helps the metal panels adhere better to the OSB.
  4. Attach the metal panels: Use appropriate fasteners to secure the roofing panels to the OSB. Ensure they’re installed correctly to prevent any future issues.

Make Your Roofing Project A Success

Choosing the right materials is crucial for a successful roofing project. With the right preparation and installation, OSB and metal roofing can work together to provide a durable, long-lasting roof for your property. As a property owner, you aspire to have a roof that’s not just aesthetically pleasing but also sturdy and durable.
