With Gutter Topper®, water flows into your rain gutters while leaves and debris stay out. Even in heavy downpours, you’ll never have to worry about overflowing gutters. In fact, Gutter Topper® has been tested to withstand 22 inches of rainfall per hour, that’s a whopping 528 inches in a day — enough to float Noah’s Ark! So whether it’s just a sprinkle or a deluge, water simply flows into pre-adjusted openings, following Gutter Topper’s curved cover and rounded edge right into your rain gutters.

Our patented design is the key to Gutter Topper’s amazing ability to handle water. The rain guard gutter system relies on surface tension, a principle of physics that makes water cling to the surface it flows over. It’s the same surface tension that makes water slide over the edge of a drinking glass and down its side. So water rolls over Gutter Topper’s rounded nose into the gutter below, but leaves, twigs, and other debris fall over the side onto the ground. Gutter Topper® is the only rain gutter product in the industry with this unique, patented ability to make water curve.

Tony Iannelli, Gutter Topper’s founder, relying on his extensive experience in the gutter cover business and a great deal of research, designed Gutter Topper® to outperform other rain gutters & systems. His patented design relies on eleven “critical bends of strength,” which not only make Gutter Topper® exceptionally effective, but extremely strong, and able to withstand the most severe weather conditions.

As the seasons change and rain turns into ice and snow, Gutter Topper® keeps right on working. Our exclusive Ice Release System™ allows snow and ice to slide right off. And Old Man Winter doesn’t stand a chance against Gutter Topper’s proven ability to withstand up to 1,200 lbs. of snow load per sq. ft.

When you install Gutter Topper® gutter guards, water goes exactly where it’s supposed to — into your gutters and nowhere else. Gutter Topper® — Tested to Be the Best™!
