Better Protect Your Assets from the Wind

Cover Boards Minimize Roofing Investment Risk

One of the greatest potential harms to your building is invisible. Without using the proper materials to hold your roofing assembly intact, strong gusts of wind can ransack your investment property. But you’re not defenseless.

There’s a simple safety measure you can take to mitigate risk and keep your building materials, tenants, and their assets secure. Including a sturdy cover board as part of the overall roofing assembly helps ensure your building operates as you intended—making you money, rather than losing it.

Why all the cause for concern?

You may be tempted to say “no” to adding a cover board altogether, if you don’t understand its full purpose. But focusing on material and installation costs upfront overlooks the potential big-ticket damage and repair costs down the line.

Wind Uplift Affects Everyone

It’s one of the most important factors to consider for protecting and maintaining a solid roof, but planning for wind uplift means more than just anticipating an extra breezy day. And it’s not specific to any one region. Regardless of what type of building you own and where it’s located, all structures are at risk of suffering from wind damage.

It’s straightforward science but too easily ignored. When heavy winds meet the side of a building, the force exerts strong pressure against the structure, pushing the air upward. This pressure builds underneath the roof, which is when the highest potential damage can occur. If the pressure under the roof is stronger than above, it’s at risk of pulling the materials apart, delaminating the roof system’s seams, leaving cracks and openings, and damaging the membrane inside.

This can lead to immediately noticeable cosmetic and structural repairs, as well as less detectable internal damage resulting in leaks, molding, and further structural damage over time. In the worst-case scenario, you may even need a complete roof replacement. Not to mention, no tenant wants to pay full price to use a building under repair. It’s impossible to put an exact dollar amount on the potential costs but it’s safe to say they’ll likely add up much faster than the price of initial cover board installation.

Cover Boards Hold Tight

When reviewing the overall cost, a cover board may seem like an extra material that would be easy to remove without anyone missing it. But adding a high-performance roof board in the cover board position (under the membrane) is actually one of the most effective ways to mitigate potential wind uplift damages for the duration of the roof’s lifespan.

Designing the roof assembly with a rigid cover board helps increase overall structural strength and protection around the costly roofing insulation and membrane materials, providing a solid substrate to hold everything in place against the added wind pressure.

Your strongest strategy to minimize the costly risk of wind damage is to approve an optimally designed roof assembly at the outset and ensure constructability through to the end. To do so, we suggest you make sure to discuss wind-damage mitigation with your construction and design team. Then remember: Cutting corners by excluding a cover board also cuts down on your protection.
