We purchased  these last year and left them up for the winter (we live in PA). It was a very mild winter and any snow that laid on the canvas we swept it off. They provide extra shade we desperately need. I wish they came a bit deeper. These replaced a retractable awning that just wasn’t ideal for the space.  I did spray weatherproofing prior to installing the awnings - *note*before they got dirty. We have a lot of pollen here and  I had to brush it off with a swifter like tool.  generally please by how well they have stood up to the elements.
