Why is LeafProof® superior to other gutter protection products?
LeafProof® is the only gutter protection product on the market today that: fits existing gutters; can be cleaned from the ground; is not screwed into the roof or fascia; and is securely installed under the first row of shingles.

How does LeafProof® work?
Each section of LeafProof® is divided by LeafProof’s® patented "S" bend. This "S" bend runs the entire length of the section of LeafProof® and it allows the contractor to bend the section of LeafProof® that slides under the shingles to match the roof’s pitch. When a section of LeafProof® is bent to match the roof’s pitch, the section that covers the gutter remains relatively flat. When water flows from the roof and over the "S" bend, the "S" bend causes the water to churn, which, along with the slope of the section covering the gutter, significantly reduces the speed of the water flow. Each section of LeafProof® completely covers the gutter to the gutter lip. When the water reaches the gutter lip, due to surface tension, the flow is reversed and enters the water channel, which drains into the gutter.

How does LeafProof® prevent leaves and other debris from entering the gutter?
If you view LeafProof® from directly above (see right) you cannot see LeafProof’s® water channel. When the flow of water reaches the point directly above the water channel, the flow will reverse direction as a result of surface tension, and the water will drain into the gutter. Most debris will not follow this reversal or is blown off the roof by the wind when dry.

Will a very heavy rain overflow LeafProof®?
No. When properly installed, LeafProof® will handle the heaviest rainfall ever recorded in one hour in America (11 inches). Rainfall this heavy is an extremely rare and dangerous occurrence. (If it is raining this hard, you will not be concerned about your gutters, you will be wondering if there is any room on the "ark") In fact, most gutter systems will overflow between 3 to 4 inches per hour. Therefore, manufacturers that advertise their gutter cover can handle 21 inches of rain an hour are misleading because most gutters cannot handle this amount of rainfall.

Is it important that a gutter cover have a pre-set water channel?
Yes, some gutter covers drain the water through a gap between the cover and front lip of the gutter. In many instances, the front lip of the gutter has been slightly bent or damaged through normal wear, which causes the width and size of the gap to vary in size. This opening creates the potential for birds or debris to enter the gutter.

Can squirrels or birds enter and build nests?
No. LeafProof® is made from aluminum, not vinyl. Therefore squirrels and birds cannot chew or peck through a section of LeafProof®. Additionally, unlike some "all-in-one gutter and gutter covers", birds cannot enter through the water channel because the opening is too small.

How can LeafProof® be cleaned from the ground?
On RARE occasions, LeafProof’s® water channel may trap some debris. This debris will be visible from the ground and may be removed using a hose with a high-pressure nozzle to clear the water channel of the visible debris.

How often will LeafProof® need to be cleaned from the ground?
This varies depending upon the type of trees surrounding your home. Generally, maple helicopter seedlings and pine needles are too heavy to follow the water flow as it enters the water channel. Lighter debris, such as oak tassel seedlings, may enter the water channel of LeafProof® from time to time. In extreme cases, this debris can be easily removed from the water channel from the ground, several times a year. This will take far less time than it does to water a garden.

Why is it important that a homeowner be able to clean a gutter cover from the ground?
Any product that is placed on the exterior of a home will require some maintenance. For example, windows and vinyl siding must be cleaned. Gutter covers are not an exception. Gutter cover manufacturers that claim their product is maintenance-free and will never clog are simply not stating the truth. LeafProof® is the only gutter cover on the market that is installed under the first row of shingles and allows you to perform this necessary maintenance without climbing on a ladder or standing on your roof.

Is LeafProof® nailed or screwed into the roof or fascia?
No. LeafProof® simply slides under the first row of shingles and the front is securely attached to the gutter lip. Products that are nailed or screwed into the roof may cause serious damage to your roof and may void many roofing warranties.

Why is it important that the gutter cover fits under the first row of shingles?
The difference in the height of a gutter cover that fits under the second row instead of the first row of shingles on a 5/12-pitch roof is approximately 1½ inches. This difference in height means that the gutter cover is much more visible which detracts from the appearance of the home. LeafProof® fits securely under the first row of your existing shingles and will provide a more finished look to your home’s exterior.

Why is LeafProof® installation more expensive than traditional gutter installation?
LeafProof® is custom-installed to fit your roof pitch while most gutters can be formed and measured to length at the job site. Since LeafProof® must be installed under the shingle, a long run of LeafProof® would be very difficult, if not impossible, to install. Therefore, LeafProof® is manufactured and installed using four-foot sections. If gutters were installed four feet at a time, their cost would significantly increase, too.

Are more expensive products better than LeafProof®?
No. LeafProof® is the only product on the market that: fits existing gutters; is installed under the first row of shingles; is not screwed into your roof or fascia; and can be cleaned from the ground. Competing products are more expensive because increased installation time greatly adds to the cost or your existing gutters must be replaced. Although some gutter covers can handle more rain than LeafProof®, this advantage is purely academic; your gutter will overflow before it will rain harder than the amount of water flow LeafProof® can easily handle.

Are vinyl products worth the cost savings?
No. While vinyl products are less expensive, all vinyl products are susceptible to animal damage, warping and cracking. Also, to properly install the leading vinyl gutter cover, the gutter must be lowered which greatly increases overall installation effort and cost. Because this significantly increases installation effort, many contractors skip this step and improperly install the vinyl covers.
