Leafguard systems are designed to limit debris entering your eavestrough while allowing water to drain properly during rain and snowmelt. Century Aluminum installs Alu-Rex leafguard systems exclusively and is Alu-Rex certified. We’ve relied on their products for over 15 years because they perform consistently in Ontario conditions.
This page explains how leafguard systems work, when they make sense, and the three Alu-Rex options we install: Gutter Clean, T-Rex, and DoublePro.
If your gutters are leaking, sagging, or overflowing, start with Eavestrough Repair before adding a leafguard system.

Leafguard systems are designed to sit over or integrate into the eavestrough opening, helping block leaves and debris while still allowing water to enter and flow through the system.
When properly installed, leafguard helps:

Gutter Clean is an Alu-Rex leaf protection system designed to be installed over existing eavestroughs, making it an ideal solution for homeowners who want to reduce clogging without the cost or disruption of replacing their gutters.
If your existing system has drainage or joint issues, we may recommend repairs first - learn more on Eavestrough Repair.
By covering the gutter opening, Gutter Clean blocks leaves, pine needles, and debris while still allowing rainwater to flow freely into the eavestrough. This helps maintain proper drainage and reduces the risk of water-related damage to the home.
The system is built from durable aluminum that will not rust, crack, chip, or warp over time. Its rigid design allows it to withstand the weight of snow and debris without collapsing into the gutter.
Seasonal performance
Summer:
When leaves and debris accumulate inside an open eavestrough, water can no longer drain properly and may overflow or flow back toward the house. This can lead to roof leaks, foundation moisture, and exterior damage. Gutter Clean prevents debris buildup, helping water drain safely away from the home.
Winter:
Eavestroughs filled with snow and ice cannot function correctly. During rainfall or warmer temperatures, trapped meltwater may seep into the roofline or walls. Gutter Clean helps keep the gutter channel clear, allowing the system to perform year-round and reducing the risk of winter water infiltration.
Key benefits include:

T-Rex is an Alu-Rex continuous hanger and leaf-protection system built specifically for new eavestrough installations. Instead of traditional spaced hangers, it uses a full-length aluminum support that strengthens the gutter while also functioning as a built-in leaf guard.
The continuous hanger reinforces the eavestrough from end to end, eliminating weak points along the run. This design allows the system to withstand heavy loads such as snow, ice, and even ladder weight—providing exceptional structural strength.
By keeping snow and ice above the gutter channel, T-Rex helps prevent internal freezing, expansion, and warping caused by repeated freeze-thaw cycles. When temperatures rise or it rains, water flows freely through the eavestrough as intended.
Manufactured from heavy-gauge aluminum, the T-Rex XL-M-5800 offers increased rigidity and durability compared to the standard M-5200, delivering longer service life and added resistance to harsh weather conditions.
Key benefits include:
Seasonal performance
Summer:
Leaves and debris can block open eavestroughs, forcing water to overflow or flow back toward the home. This can lead to roof leaks, foundation issues, and water damage. T-Rex prevents debris buildup, allowing rainwater to drain properly and safely away from the house.
Winter:
Snow- and ice-filled eavestroughs cannot function correctly. When temperatures fluctuate, trapped meltwater may seep into the roof or walls. T-Rex keeps the gutter channel clear, helping the system operate year-round and reducing the risk of winter water infiltration.

DoublePro is Alu-Rex’s most advanced leaf-protection system, engineered to combine continuous gutter reinforcement with dual-layer microfiltration. This design blocks both large debris and fine material—such as pine needles—while maintaining reliable water flow.
Unlike standard gutter guards that rely on a single perforated surface, DoublePro uses two aluminum filtration layers. The upper layer stops leaves and larger debris, while the secondary membrane prevents narrow, tapered debris like pine needles from entering the gutter. This approach reduces the risk of clogs without restricting water movement, even during heavy rainfall.
The system is designed to keep snow and ice above the gutter channel, helping prevent internal freezing and expansion that can lead to deformation over time. When temperatures rise or rain occurs, water drains normally through the eavestrough.
Constructed from heavy-gauge aluminum, DoublePro offers exceptional structural strength. It can support snow loads, ice buildup, and ladder weight, reinforcing the gutter system along its entire length.
Performance highlights:
DoublePro is backed by a lifetime clog-free warranty, even in areas with coniferous trees, with maintenance only required if necessary.
For optimal performance, this system is typically installed as part of a new eavestrough installation.

Century Aluminum installs Alu-Rex leafguard systems exclusively and is Alu-Rex certified. We’ve used these products consistently for over 15 years because they integrate well with aluminum eavestroughs and perform reliably in Canadian weather.

Installing a leafguard system increases the initial project cost due to added materials and installation time. However, leafguard can significantly reduce how often gutters need to be cleaned and help prevent recurring clogs.
Leafguard may provide long-term value if:

Yes. Many homeowners choose to add leafguard during a new install to reduce maintenance long term.
Learn more about system planning on our Eavestrough Installation page.
If a system is leaking, sagging, or draining poorly, repairs may be needed before leafguard can perform properly. See our Eavestrough Repair page for common repair issues and solutions.
Yes. If not for the benefits of a leafguard, the continuous hanger is the strongest method of attaching an eavestrough system.
Yes. Some Alu-Rex systems, such as Gutter Clean, are designed specifically for existing gutters.
Leafguard reduces debris entry and cleaning frequency but occasional inspections may still be recommended.
Yes. We offer free assessments to determine the right leafguard option for your home.
