The real cost of clogged commercial gutters
Sound familiar? These are the problems facility managers face every year.
Clogged gutters on large commercial buildings are more than an inconvenience — they're a liability.
Water Backing Into The Building
Clogged gutters overflow and water works its way into the fascia, walls, and foundation. Interior water damage, mold, and costly repairs follow.
Expensive Cleaning Cycles
Lift rental, labor, and liability. Cleaning large commercial gutters runs hundreds to thousands per visit — and most buildings need it multiple times a year.
Ice Dams & Winter Damage
Clogged gutters freeze solid in winter, causing structural stress, leaks, and dangerous ice formations at ground level below the roofline.
Contractor Scheduling Headaches
Emergency cleanouts during busy seasons mean long waits, premium pricing, and building disruptions — right when you can least afford them.
Bird & Pest Nesting
Open commercial gutters are prime real estate for pigeons, starlings, and rodents. Nesting adds to blockages and creates health and code compliance issues.
Screens & Covers Simply Don't Fit
Metal building sculpted eave gutters have a high outer edge and gutter straps every few feet. Standard guards can't be installed without cutting, trimming, and fastening around every strap.
How it works
The solution is mechanical. Just fill the gutter.
GutterBrush stops clogging by keeping debris separated and stationary. If debris can't move, it can't clump together to form a blockage — water flows through freely to the downspout, year round.
Measure Your Gutter
Check gutter width and depth. Not sure? Order a sample pack to confirm the right fit before ordering full footage — or call us and we'll advise from satellite.
Slide In 3-Ft. Sections
Clean the gutter once, then lay brush sections end to end filling the entire run. Flexible bristles self-fit to metal building, box, pole barn, and K-style gutters. No tools, no drilling.
Debris Sits — Water Flows
Leaves and seeds rest on the bristles but can't move, so they can't clump or clog the downspout. Suspended debris dries out and breaks down naturally in sun and airflow.
Easy Maintenance, If Ever Needed
No permanent modifications means GutterBrush is fully renewable. Remove sections, shake out debris, clean the gutter, and reinstall. Many buildings go years without this step.
Sizing guide
Six diameters — from small to standard to industrial
Large commercial gutters require larger brushes. Match your gutter width to the right GutterBrush diameter below. All commercial sizes ship in 3-ft. sections and can be ordered in large footage quantities.
| Brush Diameter | Fits Gutter Width | Application | Ships As |
|---|---|---|---|
| 2.25" | 3" smallest | Smallest | 3-ft. sections |
| 3.25" | 4" gutter | Small | 3-ft. sections |
| 4.25" | 5" gutter | Residential | 3-ft. sections |
| 5.25" | 6" gutter | Oversized | 3-ft. sections |
| 6.5" | 7" gutter | Commercial | 3-ft. sections |
| 8.0" | 8"+ gutter | Industrial | 3-ft. sections |
Metal building and sculpted eave gutters most commonly use the 6.5" or 8.0" brush. GutterBrush bristles are flexible and will compress slightly to conform to your gutter's unique shape. When in doubt, size up.

Why GutterBrush
Built for the demands of commercial & industrial buildings
GutterBrush isn't a residential product scaled up. The commercial sizes are engineered specifically for heavy debris loads, large water volumes, and the unique gutter profiles found on pre-engineered metal buildings, box gutters, pole barns, and industrial structures.
UV-Protected & Galvanized Core
Polypropylene bristles resist UV degradation and won't rot or rust. The galvanized steel wire core handles heavy debris loads. Backed by a 10-year material warranty — and customers have reported brushes lasting 15+ years in service.
Dramatically Reduces Cleaning Frequency
Stop scheduling emergency cleanouts. GutterBrush keeps gutters flowing through debris events — many facilities go years between gutter maintenance visits. Less labor, less liability, less disruption.
Works Where Nothing Else Fits
Sculpted eave gutters on pre-engineered metal buildings have a high outer wall and gutter straps that block every screen and cover. GutterBrush self-adapts and slides right past the straps — no trimming, no fastening.
Reduces Ice Dams & Winter Drainage Problems
Improves winter performance. The brush's dark bristles absorb solar heat to assist melting. Improved drainage means less ice buildup and fewer cold-weather overflow events damaging your building.
Stops Bird & Pest Nesting
The dense bristle fill leaves no open cavity for pigeons, starlings, or rodents to nest. Reduces pest-related gutter damage, health concerns, and the associated cleanup and pest-control costs.
Renewable — No Permanent Modification
No drilling, no fasteners, no voided roof warranties. Pull sections out, shake clean, and reinstall. GutterBrush doesn't permanently alter your gutter system — it's a completely reversible, renewable investment.

Protecting large gutter systems everywhere
From Morton buildings and municipal schools to self-storage facilities and aviation hangars — if you have a large gutter that clogs, GutterBrush was built for it.
Metal Buildings
Morton, Mueller, Butler, and other pre-engineered metal buildings with sculpted eave gutters. The most common application for our 6.5" and 8.0" brushes.
Pole Barns & Post-Frame
Agricultural and storage pole barns with large gutter systems. GutterBrush handles heavy debris loads from surrounding trees and farmland.
Aviation Hangars
Large-span hangar structures with significant roof area and high debris loads. GutterBrush protects against the overflow and water infiltration that damages aircraft and equipment.
Schools & Churches
Institutions with complex rooflines and multiple buildings. GutterBrush reduces the liability and disruption of frequent ladder access for cleaning.
Self-Storage Facilities
Long continuous gutter runs on multiple units. GutterBrush is ordered by total footage and installed in one pass — simple, fast, and effective.
Government & Defense Facilities
Federal, state, and municipal buildings with low-maintenance mandates and tight maintenance budgets. GutterBrush reduces recurring service visits.
Pool Screen Enclosures
Oversized "super gutters" on pool enclosures are a perfect fit for larger GutterBrush diameters — stops clogs that cause overflow damage to the enclosure and pool area.
Agricultural Buildings
Farm structures surrounded by trees, crops, and high debris environments. Heavy-duty bristles handle the toughest organic debris loads season after season.
Any Large Structure
If it has a gutter wider than 5", GutterBrush has a size for it. Call us with your gutter dimensions and we'll recommend the right diameter and total footage.
