FAQ

Why is the “flat bottom design” notable?

The flat bottom adds support and the cut also allows us to provide more foam which means more product which will add value and life to the product overall. GutterStufff is the only foam gutter filter that can cut this particular shape, including the flat bottom and as a result, more foam filter.

Can I use GutterStuff on a flat or nearly flat roof?

Fill out the contact form or call us at 1-866-766-3442 for additional information regarding custom foam solutions.

Does water in the gutter run over during heavy rainfall?

No. The filter is non-absorbent so it allows large volumes of water to flow right through.

Does GutterStuff® need to be cleaned?

Yes. It does require some light maintenance. Every 6 months it is recommended to use a leaf blower or garden hose to clear stubborn debris caught in the foam filter.

How do you install GutterStuff® around the gutter spikes?

It simply slides underneath the gutter spikes.  It can also be cut to fit over the gutter spikes.

Do birds, squirrels, insects, or other small animals harm the foam?

No. Not only has GutterStuff®’s durability been tested for over 5 years, but the foam filter is coated with a germicide that repels insects and keeps mosquitoes from breeding within the gutters, helping to protect against the West Nile Virus and the Zika Virus.

Do UV rays or heat from sunlight harm the foam?

No. The coating on GutterStuff® contains a UV stabilizer that protects the foam filter from the suns heat and rays.

Can strong winds blow GutterStuff® out of the gutter?

No. It is secure because it fits snugly in the gutter and under the spikes.

How long has GutterStuff® been on the market?

GutterStuff® was first marketed in the first quarter of 2003.

How does GutterStuff® perform in freezing weather?

Freezing temperatures have no effect on GutterStuff®. Since the foam filter keeps the downspout from clogging, there is never any surplus water left in the gutter, thus no freezing.

What happens in the winter? Does GutterStuff Freeze in the gutter?

Gutters will freeze for one of two reasons. First of all, if water is not able to flow to the downspout because the gutter is full of leaves and debris; it will freeze and build up as a block of ice in the gutter. Secondly, if there is heat loss in the house through the ceiling, and the heat is warming the bottom of the roof deck, the snow on the roof will melt during the day and become ice in the gutter during the nighttime hours. As this process continues over several days and nights you will end up with a frozen block of ice in the gutter, and many times this ice will continue onto the roof above the gutter and work its way under the shingles and find a way to come into your home. If you see water coming into your home from your ice dam it will be because it has come in where the nails used to hold the shingles in place are located. There is a product called ice and water shield and many homeowners in northerly climates will apply ice and water shield a minimum of 3′ up from the gutter.  We recommend at least 6′ of ice and water shield up from the gutter. That extra protection is good to have.

In the first case mentioned above, GutterStuff® may help the water to flow to the downspouts by keeping your gutters clean. In the second case where there will be a buildup of ice due to heat loss heating up the roof deck and melting the ice, GutterStuff® will become part of the frozen block of ice. When the temperatures warm up the water surrounding the foam filter will quickly melt. The GutterStuff® will be fine and continue to perform as it did prior to the winter season. It will stay in place year after year.

There is a certain amount of water that can be retained by any sediment that collects in the filter. We have not had any complaints of the foam filter becoming too heavy for the gutter so I would like to say we are pleased with our results in cold weather applications. It is true that we have sold several million feet of product in cold weather Northerly climates and have not had one complaint of this nature. We do believe this says a lot about the compatibility of GutterStuff® in cold weather climates.

In comparison, let’s examine all of the guards and screens that can be placed over the gutter. We have heard from many customers that they have become discontent because these systems inevitably become dislodged over time. It will likely take less than 2 years for a replacement to become necessary. They may look nice for a few months but give it some time, particularly if you live in a Northern climate. Snow is the screen’s worst enemy. As the snow melts and shifts, it will take the screen with it, and remove it from its place. Ice build-up will also expand and push the covers and screens out of place. Because they are over the top of the gutter and are independent of the gutter, they will not maintain their position. Over time they are sure to become dislodged due to snow and ice movement. Other environmental extremes such as cold or heat will change the dimensions of the material, making it undersized or oversized. As the original shape changes, the screen or cover no longer fits properly. When these products lose their position they no longer perform as intended and will need to be replaced. Finally, these systems are not easy to install, and you may become frustrated with your purchase, wondering whether or not you had installed them properly.
