What are leaf guards?

Leaf guards are perforated covers installed on your existing eavestrough, or as part of your new eavestrough. The holes are carefully sized to allow water to enter your eavestrough and to keep everything else out.

CanCro_Leaf-Guard-photoWe are proud to install the Alu-Rex Gutter Clean System® on existing eavestroughs and the Alu-Rex T-Rex® system on new eavestrough. They prevent birds from nesting in your eavestroughs, wasp and hornet nests, and eliminate breeding areas for mosquitos. They keep out leaves and debris and ensure that water is carried away from your roof and home as your system was designed to do.

Alu-Rex builds aluminum products of exceptional quality and, as a result, your Gutter Clean System® comes with a 40-year warranty on product performance and finish. Imagine reduced maintenance, increased safety, and great looks that last and last. Talk to one of our trained estimators today.

Will these products handle heavy downpours of rain? It looks like there aren't enough holes and they’re too small.

Alu-Rex has carefully designed the Alu-Perf leaf guards to handle the heaviest downpours. There are 489 holes every 19 inches (48 cm) and the holes are 2.8 mm (7/64") in diameter. The heaviest rainfall recorded worldwide was 12" (305 mm) of water in one hour in Holt, MO in 1947. By contrast, the 1996 Saguenay Flood in Quebec was triggered by 11" (275 mm) of rain over three days. Alu-Rex leaf guards are build to handle over 32.9" (836 mm) of water per hour.

That's almost three times the heaviest rainfall ever recorded!

If your eavestroughs are overflowing it is likely that you have:

  • a blockage somewhere in your system;
  • a general reduction in flow because of accumulated debris;
  • eavestroughs that are too narrow; or
  • not enough downspouts.

Our estimator will help you figure out the best course of action to get your system working again.

My house is surrounded by pine trees. Will this product handle lots of pine needles?

Yes. The wind will blow off the needles and leaves when dry. Whatever remains on top, including bugs and little critters, will decompose and wash through the system. Trust us, it's better to have this happen then a dead squirrel stuck in your downpipe.

A 37 km/hr wind can remove about an inch of pine needles per linear foot from the Gutter Clean System®. You can see the independent leaf guard lab results here.

My house doesn't have any trees around it. Why should I use T-Rex® or the Gutter Clean System®?

The main advantages of new eavestroughing are the strength, durability, and quality. Our eavestroughing systems will protect your home and look great for decades. New trees may grow, and your home will still be protected. Of course, new trees or not, you'll be protecting your eavestroughs from ice and snow, wasps, hornets, birds, and other critters that see an open eavestrough as an invitation to nest.

Will this product eliminate wasp, hornet, and bird nests? I'm tired of dealing with these every year.

Yes. Your eavestrough is likely the number one breeding ground for mosquitos on your property and the Gutter Clean System® will eliminate it by keeping debris from trapping water in your eavestroughs. You can read more about this, including findings by the Ontario Ministry of Health, on our Leaf Guards page.

How much maintenance is involved with the Gutter Clean System®?

None. Once installed, you can forget about it and enjoy the peace of mind that comes from not having to climb up a ladder to clean your eavestroughs. Your new eavestroughs will not only channel water away from your roofline and foundation, helping you avoid basement leaks, but it will allow the roof to dry properly and avoid the mould that often grows on the fascia.

How does your product perform in the winter with ice dams and snow?

The chance of ice dams forming will be greatly reduced as your eavestroughs will be kept flowing once leaf guards are installed. The problem with most eavestroughing is that ice builds up inside, so when snow on the roof melts there is nowhere for it to go and it gets trapped and forms more ice.

With the Gutter Clean System®, ice and snow will accumulate on top of the leaf guards and when it gets warm enough to melt, the run-off will be able to get away from the roof and to the downspouts.

Additionally, by preventing ice and snow from building up in the eavestrough, you reduce the load on the brackets and extend the life of the system.

If you currently have ice build-up at the edge of your roofline we recommend that you check if the attic space is adequately ventilated and insulated.

Do wet leaves stick to Alu-Rex products?

Only temporarily. Wet leaves will dry quickly in the sun and blow away. Because they are on a perforated surface they will dry even faster than they would on the hood of your car, for instance. A little wind is all it takes to blow away dry leaves and debris.

A 10 km/hr wind effectively removes wet leaves and about 100 pine needles per linear foot.

Even if there are wet leaves on your leaf guards, the good news is that they remain permeable. Water will still get in between and through the leaves to drain away. The exclusive design of Alu-Rex products features an approximately 0.4" (1 cm) basin which was shown in lab tests to be the correct depth to catch more water without stopping the wind from doing its job of sweeping away leaves, pine needles, and debris from the surface.

I saw plastic mesh leaf guard for sale at the store. Won't that work just as well?

No. While it may be tempting to believe that a simple plastic mesh can do the job, the opening in these products are much too large. Debris and animals can still get inside which will lead to all the problems unprotected eavestroughs already have, including mosquitos and climbing a ladder to clean them out. Moreover, these products are not rigid so they will bend under the weight of ice and snow. There just is no comparison.
