Some of the most highly rated gutter systems include LeafFilter, Gutter Topper, LeafGuard and Waterloov, according to experts at Consumer Reports. All of these systems must be installed by professionals, which increases the price but also includes free maintenance in case of clogs.
Some highly rated gutter systems that homeowners can install themselves or hire a contractor to install include Amerimax, Gutterglove Pro and Raindrop, explains Consumer Reports. These systems cost less than those installed by professionals.
Consumer Reports graded these systems on how well they withstand heavy rainfall, how well they keep debris out and how much water they are able to flow. The website also graded the self-installed gutter systems by how easy they are to use.
