All of the products manufactured by Gutter Covers International have been independently tested and certified. The key words here are “independently tested and certified.” That means someone else tested the product so there was no chance of the results being skewed in our favor. If the product failed, the product failed, and that’s what would be reported. Of course, the product didn’t fail. In fact, it passed with flying colors. We told you about the wind test - 110 mph winds with no lift or movement. It was also tested and certified to handle 22 inches of rain per hour. That’s 44 feet of rain in one day - more than Hurricane Katrina dumped on New Orleans! It was also tested and certified to withstand 1200 pounds of weight per square foot. That’s comforting to those of us who have to deal with snow and ice. See for yourself -
