Gutter Guard Testing Video
Gutter Guard Ratings
A national consumer testing magazine, September 2010, had an article rating gutter guards in which they described Waterloov as not accepting all the water and not recommended.
Unfortunately they did not have the Waterloov panels professionally installed and had installed them incorrectly, with the panel lip on top of the gutter lip instead of below, resulting in unsatisfactory performance.
Informed of their error they reevaluated Waterloov and increased its rating to recommended.
When installed correctly Waterloov gutter guards should not overshoot.
