If you are unsure or incapable of performing the Flo-Free Leaf Guard Installation, we would recommend contacting a capable, insured remodeling contractor, roofing contractor, carpenter contractor or a gutter contractor to perform the Flo-Free Leaf Guard installation for you.

• Ensure your gutters are previously cleaned, free of debris and dry before the Flo-Free Leaf Guard is installed.

The following tools are required to perform the Flo-Free Leaf Guard installation:


Before installing the Flo-Free Leaf Guard you should ensure you are capable of working safely from a secure ladder at your gutter height where Flo-Free is to be installed.

A sturdy ladder that is tall enough for the project and one that is stable enough to work upon. Please do not attempt to install the Flo-Free Leaf Guard from the rooftop.

A standard 10.2 ounce caulking gun (recommend a hooked plunger rod that can hang from the gutter during installation).

Enough Flo-Free Ultra-Seal 10.2 ounce adhesive cartridges are included in all boxes of Flo-Free Leaf Guard.

Ultra Seal is a custom blended adhesive that bonds with all types of gutter material and the Flo-Free material. This ensures Flo-Free Leaf Guard will never dislodge nor shrink from UV Sunlight unlike some competitor products. We’ve got you covered!

How do I know what size gutters are on my house?

To determine what size and style gutter will require you to have access to the gutter. (If you are uncomfortable climbing on ladders we suggest you call a professional.)

The two most common style gutters are the K-style and Half-round as shown below:

To determine the size of the gutter you will need to measure from the back to the front of the gutter mouth or opening. In most cases your measurement will be 5 or 6 inches across. Please see images below

In this example the gutter mouth measures 5 ” across. It is referred to as a 5 ” K-style gutter.

In this example the gutter mouth measures 6″ across. It is referred to as a 6″ K-style gutter.

Fascia gutters are similar in look to a K-style gutter. The face of the gutter is usually slanted, but may also have a concave appearance. In California and other Western states fascia gutters are becoming more common.

Custom Sizes will require measurements to be submitted

If you have a special type of gutter we will assist you in finding what will work best for you. Please call us at 800-622-4455.

What are the Advantages of the Flo-Free™ Leaf Guard?

  • Flo-Free™ Leaf Guard leaves 100% of the top mouth of the gutter open to accept rain water (that’s the top 5” of the gutter).  This means that it allows the gutter to continue accepting water even in the heaviest of rainfalls.
  • Flo-Free™ Leaf Guard is virtually unnoticeable when looking at your home after the installation. This is ideal for condominium communities.
  • Flo-Free™ Leaf Guard is easy to install and lasts the lifetime of your gutters. Very cost effective.
  • Flo-Free™ Leaf Guard allows maximum ‘vertical and horizontal’ water flow through your gutter system. That alone makes Flo-Free™ Leaf Guard the obvious choice.
  • Flo-Free™ Leaf Guard protects against birds and bees, mosquitos, squirrels and seagulls. That’s a blessing in disguise.
  • Flo-Free™ Leaf Guard adds value to your home. It becomes an asset to your property.
  • Flo-Free™ Leaf Guard is available for all gutter sizes.
  • Flo-Free™ Leaf Guard is very light weight and will not retain moisture. Unlike foam products that retain moisture and add unwanted weight to the gutter system.
  • Flo-Free™ Leaf Guard protects your gutters from heavy snow accumulation. That’s all-season Gutter Protection at its best!  (back to top)

Why do you have to caulk the Flo-Free in to the gutter?

When installing the Flo-Free™ Leaf Guard, we ask that you seal it in to the gutter with the custom Ultraseal Adhesive we provide you.  This will give the Flo-Free™ product the longevity to last the lifetime of your gutters and to go along with the lifetime limited warranty.  This will completely seal the Flo-Free to keep out leaves, debris, animals, & bees from entering into the gutter.  The adhesive also prevents the Flo-Free™ from getting dislodged due to animals, heavy snow load, heavy winds, large sticks or heavy snow sitting on top.  In addition, when you seal the Flo-Free™ in to the gutter, it prevents any expansion or contraction throughout the seasons, so the Flo-Free™ performs to its fullest all year round.  This has helped Flo-Free™ keep working successfully in gutters since 1989.(back to top)


What is Flo-Free™ Leaf Guard?
Flo-Free™ Leaf Guard is a gutter protection product that secures 100% to the inside of your gutter. The product does not affect the roof shingles or your roof shingle warranty, unlike other gutter protection products that attach through the roof surface. Flo-Free™Leaf Guard is made of strong, durable, ¾ inch thick, black industrial-strength nylon with built in UV protection from the sun’s solar rays. The product also has a smooth, slick, non-stick top surface that prevents anything from adhering to it. Plus, the product comes with a Lifetime Warranty. What’s more, it can handle all amounts of rain water coming off your roof. It has unlimited ‘horizontal and vertical’ water flow capabilities because only 4% of the gutter’s original capacity is affected by the product inside the gutter. That’s great news for those areas experiencing huge downpours of rain at any one time. The product does not retain additional moisture as water passes through the matrix, unlike some foam products. That makes Flo-Free™ Leaf Guard the obvious choice in gutter protection.
How does Flo-Free™ Leaf Guard work?
Flo-Free™ Leaf Guard works by keeping leaves, debris, snow and sleet out of your gutters. This allows the natural flow of rain water to run directly into the top of the gutter (vertical) and horizontally through your gutters at ‘maximum’ capacity. The product is designed to ‘see’ through the nylon matrix. This allows heat, air flow and sunlight to penetrate the gutter system and allows rain water to be filtered through. The unwanted debris sheds to the ground while the rain water flows through your protected gutter system. In addition the sunlight, heat and free flow of air completely dries the gutter system quickly and naturally. (back to top)

Does Flo-Free™ Leaf Guard Handle Downpours of Rain?
Absolutely and proven successful since 1989. Flo-Free™ Leaf Guard is very strong and porous allowing the entire gutter top to remain capable of handling any amount of rainwater. The industrial strength nylon material actually helps to draw the water into the gutter system like a water magnet because of the inherent properties of nylon. And because the interior of the gutter system remains over 95% open, large amounts of rain water can flow horizontally across the gutter system and down your spouts. Flo-Free™ is extremely popular in states that get hit hard with lots of snow and rain because it is able to handle all that water. (back to top)

Trimming Flo-Free™ Leaf Guard
Flo-Free Leaf Guard comes pre-sized from our factory to fit your homes gutter system. When installing the product using a standard set of household scissors is all that is needed to cut for the brackets and making end cuts and corner cuts. It’s that simple and your contractor will love installing the Flo-Free™ Leaf Guard. (back to top)
Metal and Slate Roofs
Ensure that ice cleats are used on metal and slate roofs because gutters can get damaged from heavy snow and ice sliding off the roof and across your gutter system.  Also the ice cleats prevent health hazards from falling ice chunks and snow slides from these types of roofs. For the safety of plants, shrubs and even human beings, please ensure ice cleats are used in these situations. (back to top)
Copper Gutters
Flo-Free™ Leaf Guard is one of the few gutter protection products that can be used with copper gutters because of the chemical reaction of metal systems with the copper. Because of the industrial strength nylon, copper gutters will not chemically react to this material as designed by our engineers. It is safe to use Flo-Free™ Leaf Guards in copper gutters. (back to top)
