Questions Customers Ask Us About Our Alu-Rex Gutter Systems

Oak Wood Texture

In a city with as much snow as Calgary, Alu-Rex gutter systems help keep you off the roof. These FAQ’s might help you feel confident about your investment.

Will ALU-Rex Leafguards Work on My Eavestroughs?

Yes! ALU-Rex products will fit onto the 5” and 6” eavestroughs found on most Calgary homes. These leafguards are designed to be installed where the hangars in your eavestrough system would normally go, allowing them to fit eavestroughs for standard asphalt laminate shingle roofs, as well as those made from tile, metal, rubber, or wood shakes.

How Long Does it Take to Install ALU-Rex Leafguards?

There is no manufacturing delay when you order ALU-Rex leafguards from Big 5. That’s because we source all the materials for the job directly from local companies right here in Calgary.

Our work trucks show up at your doorstep on the date you scheduled, with everything we need for the job. We also measure and cut all ALU-Rex products on site to fit your eavestroughs, so there’s no going back and forth to get your new leafguards.

Do ALU-Rex Leafguards Make Cleaning Eavestroughs More Difficult?

ALU-Rex products prevent the need for regular gutter cleaning, since debris settles on top of the gutters instead of inside them. Access panels can still be installed in ALU-Rex products, but most homeowners find them unnecessary.

What Warranties Do ALU-Rex Leafguards Come With?

ALU-Rex products are backed by some of the best warranties in the industry. The ALU-Rex DoublePro™ Eavestrough comes with a clog-free 360º Lifetime Warranty, while the T-Rex® Eavestrough carries a Lifetime Warranty on sturdiness.

Alu-Rex guards installed alongside new eavestrough are backed by our Big 5 Year installation warranty in addition to the materials warranty provided by Alu-Rex.

What Are the Main Benefits of ALU-Rex Leafguards?

Our ALU-Rex T-Rex leafguards are a continuous hangar system, which means there are no seams to worry about. 

ALU-Rex T-Rex leafguards are also rated for up to 250lb per linear foot, which means they will not easily become detached from your eavestroughs. They are designed to remain firmly attached through a wide range of challenging environmental conditions without deforming or collapsing.

How Do ALU-Rex Leafguards Protect Your Eavestroughs in Winter?

ALU-Rex leafguards protect your eavestroughs year-round by causing snow and ice to settle on top of the gutters instead of within them. This keeps your eavestroughs functional throughout freezing and thawing cycles, making them ideal for Alberta winters.

How Do ALU-Rex Leafguards Clean Themselves?

Once debris settles on top of your ALU-Rex leafguards, all it takes is a light gust of wind to blow it away. Wet debris will be heavier, but once it has had a chance to dry naturally in the open air it will also be carried away easily by the wind.

All ALU-Rex leafguards are specifically designed so any debris that collects on top will be exposed to wind and carried away from your eavestroughs.

Why Should You Have ALU-Rex Leafguards Professionally Installed?

ALU-Rex leafguards must be measured and cut to fit your existing eavestroughs. Since the process is bespoke for every house, it’s best to let a professional contractor take care of it instead of trying to do it yourself.

Hiring Big 5 to install your ALU-Rex leafguards also reduces your risk of personal injury and ensures your new leafguards will be set up effectively. For more information on having ALU-Rex products professionally installed, contact us and speak with our team.

Safe , professional, site was always clean. No chatting, no music, just 2 quality tradesmen getting the project done. They noticed a couple spots on second story where the caulk was letting go...they noticed and they fixed...i wouldn't have known if I didn't see them. Site was cleaned up like nothing happened.
