Gutter Topper is exactly what its name says, a top for your gutters. Gutter Topper installs over your existing gutters and uses a reverse curve system so that rain water flows into your gutters, but leaves, needles, and other debris does not enter the gutters.
The Gutter Topper product is very similar to the other gutter products on the market. It uses reverse curve gutters that others use so there is actually very little to differentiate it from the other products. They even advertise the Best Housekeeping seal like Leaf Filter does.
If your gutters are already in bad shape then it would probably not be worth spending the money to add this gutter cover. It would be more worthwhile to completely replace your gutters with a new product. However if your gutters are currently in good condition you might be able to save some money because you can reuse your existing gutters.
Due to their advertising I’m guessing that the quote to install Gutter Topper will be high and that they will use a high pressure sales pitch. If you can confirm or deny that then please leave a comment below.
