FAQS
Things Calgarians Need to Know About Alu-Rex Leafguard Gutter Systems
Calgary winters are no joke. Alu-Rex gutter systems are designed to handle heavy snow loads and help keep you safely off the roof. These FAQs will help you invest with confidence.
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 hangers in your eavestrough system would normally go, fitting 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. We source all materials directly from local companies right here in Calgary. Our work trucks show up on the date you scheduled with everything needed for the job, and we measure and cut all Alu-Rex products on site to fit your eavestroughs.
Do Alu-Rex leafguards make cleaning eavestroughs more difficult?
Alu-Rex products eliminate the need for regular gutter cleaning, since debris settles on top of the gutters rather than inside them. Access panels can still be installed, but most homeowners find them unnecessary.
What warranties do Alu-Rex leafguards come with?
The Alu-Rex DoublePro™ Eavestrough comes with a clog-free 360º Lifetime Warranty, while the T-Rex® Eavestrough carries a Lifetime Warranty on sturdiness. Guards installed alongside new eavestroughs are also backed by our Big 5 Year installation warranty.
What are the main benefits of Alu-Rex leafguards?
Our Alu-Rex T-Rex leafguards are a continuous hanger system with no seams to worry about. They are rated for up to 250lb per linear foot, meaning they will not become detached and are designed to remain firmly attached through a wide range of challenging environmental conditions.
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.
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 handle it. Hiring Big 5 also reduces your risk of personal injury and ensures your new leafguards are installed effectively.
