Frequently Asked Questions

Only temporarily. The Alu-Rex eavestrough cover (Gutter Clean System leaf guard) and the eavestrough fastening system (T-Rex) boast a smooth, perforated surface. Just as they may temporarily stick to the hood of your car, leaves and debris that land on the surface of Alu-Rex eavestrough products dry quickly in the sun. And unlike your car hood, the surface beneath the wet leaves on your eavestrough is perforated so they dry faster!

A little wind is all it takes to sweep away dry leaves and debris:

• A 10 km/h wind effectively removes wet leaves and about 100 pine needles per linear foot.
• A 37 km/h wind can remove about an inch (2.5 cm) of pine needles per linear foot.

The Alu-Rex eavestrough fastening system and eavestrough cover significantly reduce the weight of snow on your eavestroughs. Since the snow can’t get into the eavestroughs, the weight they have to carry is limited to that which accumulates on top of Alu-Rex gutter cover. What’s more, the eavestroughs remain fully functional so water from melting snow and ice can drain away freely.

Without Alu-Rex eavestrough fastening system or cover, the eavestroughs-already clogged with leaves and debris-fill up with snow and ice, which keeps them from doing their job and draining water away in spring. Plus they have to bear more weight.

Not at all! Water continuously drains into the downspout because nothing-neither debris nor snow-will block it from draining. With Alu-Rex eavestrough fastening solution and Gutter Clean System and the Alu-Perf gutter cover technology, your eavestroughs work all year round.

Alu-Rex eavestrough fastening solution and Gutter Clean System do not cause ice formation. If ice forms on the edge of the roof, we recommend that you check if the attic space is adequately ventilated and insulated.

No. The Alu-Rex eavestrough fastening system T-Rex and Gutter Clean System leaf guard do not cause any leaks. No shingles are raised and no nails or screws go into the roof during installation.

Beware of look-alike products that require you to lift the shingles. These products can lead to leaks. In time, the asphalt shingles dry out and become brittle. It’s never a good idea to lift shingles when installing gutter protections systems, whether they’re nailed in, screwed on, or simply set in place.

Also, the manufacturer’s warranty on asphalt shingles is void if the shingles are lifted, peeled away, or modified.

The maximum weight your eavestrough can bear with T-Rex eavestrough fastening system is 250 lb. per linear foot (373 kg per linear meter). That’s 50% stronger than with spikes or hangers.

This photo is real and has not been doctored in any way. Three men can hang from an eavestrough installed with the T-Rex continuous gutter fastening system for new eavestroughs.

Yes. Alu-Rex installation standards require your eavestroughs to be equipped with prefabricated Alu-Rex corners. They are removable and give access to the inside of eavestroughs.

The only restriction consists of making sure the fascia board is not inclined, which is very rare. However, the Gutter Clean System works with eavestroughs installed on inclined fascia boards.

It may seem unnecessary to use the T-Rex continuous eavestrough fastening system if there are no trees around your home. But T-Rex’s main strengths are its robustness, strength, durability, and quality.

With T-Rex, your eavestroughs will be stronger and more durable than any others. New trees may grow. and your eavestroughs will still be in perfect condition after 25, 30, and even 40 years!

People who buy the T-Rex system want what’s best for their eavestroughs, just as they do for their doors, windows, and all other components of their home.

Spikes, screws, and hangers provide a certain degree of strength, but only over a few inches to either side of them. The spaces between the spikes/screws/hangers are weak. With the T-Rex gutter fastening system, your eavestrough is equally solid across its entire length. There are no weak spots. Your eavestrough will also benefit from getting protected using the Alu-Perf gutter cover technology.

The Gutter Clean System leaf guard is an eavestrough protection system that prevents leaves and debris from getting in and clogging the existing eavestroughs. This product is simply placed on your home’s existing eavestroughs.

T-Rex is a continuous fastening system for new eavestroughs that very securely fastens eavestroughs to your home, making them 50% stronger than traditional systems.

Both products use the same Alu-Perf eavestrough cover technology, which prevents leaves and debris from building up in your eavestroughs.

The Gutter Clean System leaf guard and T-Rex, the eavestrough fastening system are among the most efficient eavestrough protection systems on the market today. In the vast majority of cases, a light breeze is enough to sweep away normal debris. In areas under the roof or under shallow overhangs on sloped roofs, debris may build up where the wind cannot reach it. We recommend that you occasionally clean out these areas to keep your Alu-Rex products in good working order.

T-Rex is the best choice! Both products can be installed to protect your eavestroughs from leaves and debris, but only T-Rex makes your new eavestroughs 50% stronger than conventional systems. Since there’s no significant difference in installation costs, take advantage of the strength and durability of the T-Rex eavestrough fastening system!

Yes. The Gutter Clean System works with 4 in. (10.1 cm), 5 in. (12.7 cm), and 6 in. (15.2 cm) eavestroughs made of steel, aluminum, copper, or zinc.

Yes. The T-Rex continuous eavestrough fastening system is perfect for steel, aluminum, or zinc K-style (O’gee) or Half-Round eavestroughs that are 5 in. (12.7 cm) and 6 in. (15.2 cm) wide.

No. Our eavestrough fastening system and gutter covers have been tested on a number of plastic and vinyl eavestroughs. In most cases, they did not meet our rigorous quality standards.

Our exclusive Alu-Perf gutter cover technology is the result of extensive research and development. The product has 624 holes every 24 inches (61 cm). This allows water to drain at the same rate as a 2 in. x 3 in. (5 cm x 7.5 cm) downspout. Rigorous testing by an independent certification agency has proven that Alu-Rex gutter cover can drain over 29,7 in. (755 mm) of water an hour over a length of 20 feet (6 m). And with 32,000,000 feet (9,750,000 metres) of Alu-Rex products installed around the world, the figures speak for themselves.

Note: The highest amount of rainfall ever recorded worldwide was 12 in. (305 mm) of water in one hour (Holt, MO, 1947). In comparison, the 1996 Saguenay Flood in Quebec was triggered by 11 in. (275 mm) of rain in three days. Alu-Rex products would have been able to handle all that rain in just one hour-and three times more!

Overflow is usually caused by the eavestroughs themselves (not wide enough or deep enough for the roof surface) or the downspouts (insufficient number for the roof’s surface). It is important to make sure there are enough downspouts to avoid this problem. For this purpose, you need to keep in mind that one downspout is enough to drain the equivalent of a 600 sq. ft. (56 m2) roof.

In short, if you don’t have backflow problems with your current eavestroughs in heavy rainfalls, the Gutter Clean System and T-Rex won’t create them.

No. Alu-Rex eavestrough fastening system and eavestrough cover are made of aluminum, or copper. They will never rust. They come directly from our supplier’s plant in the natural colors of the materials. The finish and the performance are guaranteed for 40 years.

No. Alu-Rex products are practically invisible from the ground.

Alu-Rex eavestrough fastening system and eavestrough cover leaf guard have been tested in certified laboratories with no business ties to us. Moreover, the first prototypes of Alu-Rex eavestrough fastening system and eavestrough cover were installed in Canada (where weather conditions are harsh) some 10 years ago and they still deliver outstanding performance. The 32,000,000 feet (9,750,000 metres) of Alu-Rex eavestrough fastening system and gutter cover installed around the world also speak volumes about their durability.

Absolutely. There is a model for every setup. There’s even a version of the Gutter Clean System that can be installed on screw-on hangers. All models offer the same great results.

Alu-Rex eavestrough fastening system and gutter covers come with a 40-year warranty on performance and quality. The finish is guaranteed for 40 years.

Even if all the perforations get covered-which never happens because the wind sweeps away leaves and debris-Alu-Rex eavestrough fastening system and eavestrough cover leaf guard can drain up to three times the quantity of water ever recorded in the heaviest rainstorm.
How? Because wet leaves remain permeable. Water still gets between the leaves-and even through them-to drain into the eavestrough. The water always finds its way into the holes.

What’s more, the exclusive design of Alu-Rex products features an approximately half inch (1 cm) deep basin. Testing in the lab and in the field has shown this to be the right depth to catch more water without stopping the wind from doing its job of sweeping away leaves, pine needles, and debris from the surface.

Beware of look-alike products that are completely flat. Water can overflow when products are not equipped with a basin.

No. The Gutter Clean System leaf guard and T-Rex, the continuous eavestrough fastening system never come into contact with the roof. That means you can have your roof redone without removing the Gutter Clean System or T-Rex.

It’s tempting to believe that a simple plastic mesh that sells for $4 per 20 foot (6.1 metre) roll can do the job, but this just isn’t the case.
The openings in these products are much too large. Debris can get inside and leaves get stuck, which can clog the eavestroughs and turn into fertile soil for plants to grow in.

Moreover, these products are not rigid so they bend under snow and ice.

In short, these products will still force you to periodically climb a ladder to clear out your eavestroughs.

For all these reasons, we believe that our slogan says it all: Works the first time. All the time!
