How It Works

The Science Behind Gutter Topper

The key to Gutter Topper’s amazing ability to handle water and repel leaves and debris is found in the science of its patented gutter cover design.

Water clings to the surface on which it travels. This "surface tension" causes the water to cling to Gutter Topper’s rounded "nose." The water literally follows the curve of the nose and is deposited in the slots at the bottom of the system. (Your Gutter Topper retailer will be glad to demonstrate this on a section of Gutter Topper using water from the faucet in your sink. You almost have to see it to believe it. Every drop goes where it belongs. Not one drop goes astray.)

Leaves and debris, on the other hand, won't follow the curve. They'll remain on Gutter Topper's flat surface and blow harmlessly to the ground once they dry out. Our frequently asked questions will tell you more.

Tested & Certified

Independently Tested to Be the Best

PRI Construction Material Technologies, an independent testing firm for the roofing and construction industries, certified the Gutter Topper gutter cover system against the worst Mother Nature could dish out. Gutter Topper - Beautiful - Safe - Strong.

The Wind / Rainfall Test

Certified to resist winds of up to 110 mph (met Florida's Miami-Dade County standards, some of the strictest in the U.S.) This is the equivalent of a Category-2 hurricane. Certified to handle downpours of up to 22" per hour / 528" per day. The record one-day rainfall is 43 inches recorded in Alvin, Texas on July 25, 1979.*

The Load Bearing Test

Certified to withstand up to 1,200 lbs. of weight per sq. ft. Gutter protection that's good to have if you have to deal with snow or ice.

Consumer Gutter Rating

Gutter Topper is the Highest Rated "Surface Tension" System

A leading consumer magazine tested a number of gutter guard systems for debris and performance. Of the gutter guard systems, Gutter Topper was a recommended choice and the highest-rated "surface tension" system.

Gutter Topper was tested for debris buildup, wind and rain in independent tests. Gutter Topper gutter guards exceeded expectations in all three categories:

On Debris - Gutter Topper was rated Excellent

Debris is based on a mixture of leaves, bark, twigs and pine needles. The test conditions and methods were developed to simulate normal conditions that occur in most areas of the United States.

On Wind — Gutter Topper Withstood Winds of 110 mph
(Equivalent to a Category 2 Hurricane)

Wind is the ability to withstand straight line winds without any lift or movement.

On Rain — Gutter Topper Handled the Equivalent of 22 in. of Rainfall Per Hour

Again, no competitive gutter guard system has scored higher in any category than Gutter Topper in independent testing. Independent testing confirms you make a wise choice when you select Gutter Topper.
