    McCaughan's Everflow Eavestroughing offers a top quality service to homeowners and businesses. Our Alu-Rex certified installers have the knowledge to answer your needs in order to keep your eavestrough maintenance-free.

    No. Alu-Rex products are made of aluminum. They will never rust. The product is guaranteed for 25 years.

    Only temporarily. Alu-Rex products 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 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.

    No water infiltration can be caused by the Gutter Clean System® Leaf Guard. 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.

    The exclusive Alu-Perf technology is the result of extensive research and development. The product has 489 holes every 19 inches). This allows water to drain at the same rate as a 2 in. x 3 in.) downspout.

    Rigorous testing by an independent certification agency has proven that Alu-Rex products can drain over 32.9 in. of water an hour over a length of 20 feet. And with 44,000,000 feet 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. of water in one hour (Holt, MO, 1947). In comparison, the 1996 Saguenay Flood in Quebec was triggered by 11 in. 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. roof.

    In short, if you don't have backflow problems with your current eavestroughs in heavy rain falls, the Gutter Clean System® and Fixa-Tech® won't create them.

    No. Other products may be significantly more expensive for three reasons:

    1. Installation is more time-consuming and complex. Installers have to be paid fairly for the time they spend installation the product. As such, hard-to-install products will cost more.


    2. The material used is more expensive. Manufacturers want to make a profit on their sales. So if the manufacturing cost is high, the consumer has to expect to pay more. For example, the cost of manufacturing certain products (PVC, vinyl) can fluctuate with the raw materials market.


    3. Most competitors are franchises of major American companies and must charge consumers more to pay franchise fees and corporate advertising costs.

    Thanks to their recognized effectiveness and easy installation, Alu-Rex products are the top choice of most qualified installers and there are no franchise fees or royalties to pay. This results in a fair price for consumers!

    Even if all the perforations get covered which never happens because the wind sweeps away leaves and debris. Alu-Rex products 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 0.4 in. (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.
