Alurex Gutter Guard – Alu-Rex Gutter Review & GutterBrush Option
Alu-rex Gutter Guard
When homeowners or gutter professionals search for Alu-Rex, Alu-Rex gutter, or Alu-Rex gutter guard, they want clear information about how the system performs and how it compares to other gutter protection options. Alu-Rex (also referred to here as Alurex) has earned a strong reputation for durability, innovation, and its unique continuous gutter guard technology.
This guide introduces the Alurex gutter guard system for both contractors and homeowners—and also presents GutterBrush, a simple, flexible, and highly effective alternative available in six sizes. Whether you install Alu-Rex or already own it, this article gives you a complete understanding of how the system works, its advantages, its limitations, and when GutterBrush might be the better choice.
GutterBrush can be installed into any gutter including an Alu-Rex gutter. GutterBrush is an option fort any gutter, which makes it a great Alurex Gutter Guard.
What Is the Alu-Rex (Alurex) Gutter Guard System?
Alu-Rex offers several gutter guard styles, including T-Rex®, Gutter Clean®, and DoublePro®. All versions rely on perforated aluminum top covers that prevent large debris from entering the gutter while allowing rainwater to flow through.
A significant feature of the Alu-Rex system is that the gutter guard is often installed simultaneously with the gutter, forming a unified structure. This makes Alu-Rex gutters extremely strong compared to standard gutters that rely on spaced hangers.
Why Alu-Rex Gutters Are Stronger Than Standard Gutters
The strength of the Alu-Rex gutter system comes from the fact that the guard acts as a:
Continuous cross-bar hanger
Instead of hangers every 16–24 inches, the gutter guard itself spans the full length of the gutter, making the entire system:
-
More rigid
-
Better supported
-
Snow- and ice-resistant
-
Less prone to sagging
For homeowners in regions with heavy ice, Alu-Rex offers impressive performance. It is a very fine gutter and the Alu-Rex gutter guard is a very fine gutter guard.
The Rain Water Ramping Limitation of Flat Gutter Guards
Even with all of its strengths, Alu-Rex shares a challenge common to every flat or nearly-flat gutter guard, regardless of brand or material:
Flat guards can create a "ramping effect."
During heavy rain:
-
Water rushes off the roof
-
Gains speed
-
Hits the flat guard surface
-
Shoots straight over the gutter edge
-
Gets dirty, holes fill with pollen or get covered; Water overshoots the gutter.
This phenomenon is not an Alu-Rex design flaw—it's the unavoidable physics of water traveling across a smooth horizontal surface. Even micro-perforations cannot always accept extremely fast water flow.
Many contractors have seen this firsthand with all flat gutter guards, including micro-mesh, perforated aluminum, and solid covers.
GutterBrush is different, no other gutter guard accepts rain water better than GutterBrush

A Hidden Contractor Concern: Removing Alu-Rex in the Future
While Alu-Rex’s strength is a major benefit, it also presents a structural issue if removal is ever required.
Because the guard is the support system, removing it means:
-
The gutter loses its structural integrity if the gutter guard is removed.
-
The gutter has no hangers, other than the gutter guard.
-
The gutter becomes weak or may deform
Situations that may require guard removal include:
-
Gutter Guard Gets Clogged, Sending Water Past the Gutter (overshoot)
Alu-Rex owners should be aware of this before installation.
Introducing GutterBrush as a High-Flow Option
Many contractors who install Alu-Rex also offer GutterBrush as an option for customers who want a simpler clog-prevention method with no ramping issues and easy long-term maintenance.
Instead of covering the gutter, GutterBrush fills the gutter with cylindrical brush sections made of stiff bristles surrounding a central wire core. Water flows freely through the bristles while debris cannot clump together to block the downspout.

How GutterBrush Performs, Alu-Rex Gutter Guards
1. Water Flow and Overshoot
Because GutterBrush sits inside the gutter, it does not create a ramp. Water falls naturally into the gutter channel as intended.
2. No Downspout Clogging
GutterBrush protects the gutters, downspouts and in ground storm drains from clogging.
3. Winter Performance
The black bristles absorb heat, accelerating melt and reducing ice buildup. Snow rests on top of the brush while meltwater flows underneath—preventing the snow clogs that start most ice dams.
4. Installation and Maintenance
There are no screws, no fasteners, no brackets, no cutting, and no tools.
Just slide the brushes into the gutter. Fill the whole gutter.
To clean: pull them out, shake them, reinstall.
5. Structure
GutterBrush does not alter gutter structure.
Your gutter remains fully supported by its original hangers and can be serviced normally in the future. Slide GutterBrush under common crossbar hangers also known as horizontal hidden hangers.
Why Installers Offer Both Alu-Rex and GutterBrush
Contractors find GutterBrush valuable because:
-
It installs in minutes, not hours
-
It fits any gutter already on the house as well as Alu-rex gutters.
-
It handles heavy rain extremely well
-
It can be added during gutter cleaning or roof work
-
It provides a lower-cost solution for price-conscious customers
GutterBrush does not compete with Alu-Rex—it complements it by offering a second option where ramping, maintainability, or winter performance are concerns.
Conclusion: Choosing the Best Gutter Protection for Your Home
The Alurex Gutter Guard (Alu-Rex) system is a strong, well-engineered gutter protection solution. It strengthens gutters and performs well in many regions. However, like all flat gutter guards, it can overshoot during heavy rainfall; especially when leaves lay on it, and can’t be removed without impacting gutter strength.
GutterBrush, available in six sizes, offers a simple, tool-free method to stop gutter clogging while maintaining extremely high water flow. Its open-air design prevents downspout blockage and performs exceptionally well in winter.
Both systems have their place. Contractors and customers who understand the differences can choose the solution that best fits their home, budget, climate, and maintenance preferences.
