Install Impact-Resistant Skylights

05/03/2023

Why do they matter?

If you do not have wind or impact-resistant skylights, you may want to consider replacing them with newer models that are tested and approved to resist wind pressure, windborne debris impacts, and hail.

What do I need to know?

The best time to replace skylights is during re-roofing. Removing the old roofing material will provide easy access to replace the skylights with wind- and impact-rated types that do not need any additional coverage in high-wind events like hailstorms, hurricanes, or tornadoes. This is important as it is not only inconvenient to cover skylights before a hurricane, but it is nearly impossible to protect them before a hailstorm or tornado strike.

Where do I start?

Replacing your skylights

• Check with your local building department for information about the wind speed rating and windborne debris protection requirements your skylights should meet.
• Be sure to follow the manufacturer's specifications when using or installing skylights as improper installation may cause a voided warranty or, worse, a product failure that presents a threat to life and property. Learn more about installing windows and skylights here.
• Select skylights that meet the Design Pressure (DP) ratings for your location.
