Looking for a way to keep the gutters on your large commercial building, free from frustrating and expensive clogs? You found it with the 6.5-Inch or 8.0-Inch diameter GutterBrush Leaf Guard for commercial and industrial buildings.

These low-maintenance gutter guards are constructed of a durable twisted in wire brush you simply slip into the full length of your gutter. The brush keeps out leaves, twigs and debris while letting the water flow freely through your commercial-grade gutter. Each box includes 36-inch lengths and a couple 18-inch pieces to let you choose the size that works best for you. Both install easily to keep water flowing through your gutter.

Available in two different widths and lengths, you can go for the 6.5-Inch diameter GutterBrush Leaf Guard for Large / Commercial 7-Inch Gutters or the 8.0-Inch diameter GutterBrush Leaf Guard for the largest 8-Inch Gutters found on Metal or industrial buildings . Both gutter designs come with two different length options:

1) 7-Inch GutterBrush: Comes in boxes with 21- and 45-foot options; has a 6.5-inch diameter

2) 8-Inch GutterBrush: Comes in boxes with 18- and 36-foot options; has an 8-inch diameter

The lengths included are based on how much gutter you will need to cover. While the large and extra-large GutterBrush Leaf Guards are typically not the size for your residential home gutter, you will find the larger sizes ideal for:

1) Metal and steel buildings

2) School and church gutters

3) Commercial and industrial facilities

4) Super gutters or pool screen gutters

Measuring your commercial-grade gutters is the fastest way to gauge the size you need. The 7-Inch GutterBrush is designed for gutters of that size, but it can be placed in a larger gutter and still prevent clogging. The 8-Inch GutterBrush also solves clogs and keeps water flowing in a larger 9-inch custom gutter.

You want to fill the width of the gutter as fully as possible without overly compressing the bristles. In some cases it may be desirable for the brush to have a crowned or raised profile, which is slightly higher than the outer edge of the gutter. This allows the wind to purge leaves from the brush. The raised profile is not necessary and not always possible.

When a raised profile of the brush is not desirable or possible:

1) Some commercial buildings have a raised gutter outer edge that is actually higher than the roof drip edge. Having a gutter brush raised higher than the roof drip edge is usually not desirable.

2) Many gutter styles have a width that is different than the height. If a gutter is taller than it is wide, a raised profile would not be possible.

Getting the right size:  To decide which GutterBrush size will work best inside your gutter, you can measure the inside dimensions to determine which GutterBrush product will best fill your gutter (without overly compressing the bristles.)   Such can be a challenge because many  gutters have complicated shapes with multiple angles and corners. The best way to be sure you purchase the best size is to set 3 different samples in the gutter as follows. 

1)  Buy our commercial sizing sample pack ( SKU smp-com ) which contains 6" length samples of all 3 of our largest commercial sizes: for $ 9.95

2)  Once received, set each sample in the gutter and decide which size best fills the width of the gutter without overly compressing the bristles   Be careful to purchase the commercial sizing samples and not the residential.   Click here to go to Sizing Samples

3)  Another option is to print and use our sizing chart to (scissors) cut out circles that match the diameter of each of our brushes, set these circles into the gutter to determine the best fit. Click here to go to the sizing chart

Customers love GutterBrush for their metal building  (steel building) gutters because installation is so fast & easy , it keeps gutters from clogging, and it keeps in ground storm drainage clear too!   People with these types of gutters are very limited because other gutter guard products are not appropriate for these gutter configurations, do not fit, and require labor intensive work in order to customize the gutter guard to fit continuously.  Most metal buildings have gutters which the front edge is much higher than the back edge and also higher than even the roof drip edge; they are built this way for aesthetics, so that when looking from the ground you do not see the ribs of the roof.  For gutter strength they typically strap or hang the outer front edge of the metal building gutter to the upper portion of the roof panel ribs, therefore, the market has many varying/different gutter profiles and measurements depending on the slope of the roof. The building is actually more aesthetically pleasing with the high gutter edge hiding the roof drip edge.  Unfortunately, when such a gutter clogs and fills up with water, often the gutter is at risk of leaking back into the building because the rear edge is lower, therefore the natural  path of least resistance is for rain water to leak back into the building .  Customers rely on GutterBrush because they desperately need a system to keep the gutter from clogging so they can avoid these leakage problems.   To continue to forever avoid gutter clogs, at some point, Gutterbrush can be easily renewed because there are no fasteners; simply remove the brushes, bang the debris out, clean the gutter and re-install GutterBrush completely renewed.

Video Title:  Metal Building Gutter Guard

Description: Metal Building gutters and steel building gutters are shaped and attached differently than common gutters. Due to the shape and attachment, standard gutter guards, gutter screens , gutter covers and gutter guard devices will not fit and will not work with metal building gutters. This video outlines some of the major differences in these gutters and explains how the GutterBrush gutter protection system keeps gutters from clogging and is fast and easy to install into metal building gutters with no tools and no fasteners required.

Transcription: Hi,  my name's Alex with Gutterbrush.   Metal buildings, also referred to as Steel Buildings, are designed with a unique gutter system that has some very different physical characteristics. Due to the fact that metal building gutters are different in shape and attachment, the typical gutter screens, gutter covers, and typical gutter protection devices do not fit and will not work on metal building gutters.  This causes a challenge for metal building owners because like other buildings, they may be placed close to a tree line so they may have difficulty keeping the gutters from clogging. And like other building owners, metal building owners also need to decrease building damage that can occur from overflowing gutters such as landscape erosion,  compromised foundations, general building damage, rust, and rotted cap flashings while simultaneously keeping the in-ground storm drainage from clogging. Steel Building owners, property managers, and contractors are turning to GutterBrush to provide a simple inexpensive gutter clog protection system for metal buildings that's fast and easy to install and maintain,  Metal or Steel buildings are a " one design fits all " prefabricated building system. They designed these building systems to have a very high front edge of the gutter. This high front gutter edge, is more aesthetically pleasing. The front edge of the gutter is so high it hides the visual appearance of the ribbed roof and it also miters or connects evenly with the rake trim for a very smooth and neat appearance.  For added gutter strength, the outer front edge of the gutter is strapped or connected to the upper ribs of the roof. The result is a very strong gutter that looks great from the ground but poses many gutter cleaning and gutter guard challenges.   Due to the fact that the front outer edge of the gutter is designed and intended to be so high and is even higher than the drip edge,  and the fact that the front edge is strapped directly to the upper ribs of the roof,  retrofitting these gutters with a typical leaf filter, gutter screen or gutter cover is near impossible.  Every gutter hanger is in the way, and the roof drip edge is way down lower than the outer edge of the gutter, so metal building owners are extremely limited in what is available to keep their gutters flowing;  not to mention the important task of keeping the in ground storm drains from clogging. As an additional obstacle, often the roof drip edge is extended further than it needs to be making it practically impossible to fit your hand in there to clean the gutter.   The GutterBrush rain gutter clog protection system comes in five different sizes, keeps gutters flowing and works great! It is very fast and easy to install in metal buildings. Get a sample box that contains three different sizes in one box, to help you choose the right size then once you've chosen the right size fill the entire gutter from an end to end with three foot lengths of gutter brush by sliding them under the gutter brackets. Fill the entire gutter from end to end and leave GutterBrush in place year round to keep gutters from clogging and protect downspouts and storm drains too. The long-lasting brush fills the gutter and keeps the debris from clogging while the water flows between the bristles.  The flexible bristles even allow you to fit Gutterbrush into very small or tight gutter openings. The beauty of Gutterbrush is the speed and ease of fitting and installing with no fasteners so that at some point when maintenance is necessary, it's a snap. You just pull them out, shake the debris out, clean the gutters and reinstall Gutterbrush completely renewed. In short, steel building manufacturers, contractors, owners and property managers love Gutterbrush because it provides the clog protection that they need while being fast and easy to install manage and then maintain, on gutters that typically have very few available options. GutterBrush is available at HomeDepot.com or direct from the manufacturer.
