The Damaging Effects of Wind Uplift

Regardless of what type of building you own and where it’s located, all structures are at risk of suffering from wind damage, most specifically wind uplift. When heavy winds meet the side of a building, the force exerts strong pressure against the structure, pushing the air upward and across the roof. 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, causing damage to the roof structure and often leading to roof failure.

This can lead to immediately noticeable structural and cosmetic 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.

Wind damage can lead to cracks and openings in the roof assembly, leaving passageway for moisture to intrude and weaken the entire roofing system over time. The cost of repair and replacement quickly adds up

More Than Just a Strong Gust

Adding a high-performance DensDeck® Roof Board as a cover board strengthens the entire roofing assembly, helping mitigate the risk of damage that often comes with storms and severe winds.

Depending on the direction and speed when it hits, wind can wreak havoc on a building in a variety of ways:

Detached Membrane

Adding a cover board to the roofing assembly provides extra membrane protection with a reliably sturdy surface to adhere to against wind damage.
Loss of Structural Integrity
icon
Cover boards add strength to the assembly, reinforcing the roof’s structural integrity to better hold against the force of the wind.
Exposed Insulation
icon
The cover board’s strong gypsum core to glass mat bond boosts the assembly’s wind protection by helping hold the membrane to the roof, which can then prevent exposing the membrane and insulation to damage.

Added Strength Against Moisture and Puncture

Doubling DensDeck® Roof Boards’ resistance to moisture, built-in EONIC™ Technology makes DensDeck® Prime and DensDeck® StormX™ Prime cover boards the only boards on the market with manufacturing specifications that include 5% total water absorption resistance by weight and 1-gram surface water absorption performance on both sides of the board.*

* Based on published manufacturing specifications as of December 1, 2017.

NOTE: Moisture has a detrimental effect on every cover board, including DensDeck® Roof Boards and every effort should be taken to keep them dry before, during and after installation. Damage or reduction in performance resulting from exposure to more than an incidental amount of moisture is NOT covered by the limited warranty for DensDeck® Roof Boards. For additional information on installation guidelines and product warranty, please see Resources.
