Even in the strongest winter in your area you shouldn’t worry about the slope or if you should leave your louvered roof open or closed. If designed with our engineering, your cover should withstand any type of snow (our generic engineering is designed up to 30 pf (per square foot).
For example, if you have a 20×15 patio cover our system is designed to carry up to 9,000 pounds on your cover, open or closed.
We have been in the business for more than 25 years and we are the only international louvered roof system. Our louvered roof system, has seen the snow in the Swiss Alps, Bariloche in Argentina, Aspen Colorado, and upstate New York,however when there are heavy loads of snow on top of your louvered roof system, it should not be opened or closed.
