FAQS
Things Calgarians Need to Know About Eavestroughing
With all the crazy weather in Calgary, eavestroughing is a must. These FAQs might help you feel confident about your investment.
What do eavestroughs do?
Eavestroughs protect your home from rainwater by carrying it away from the foundation. Without eavestroughs, your home is almost certain to experience water damage over time due to rain, snow, and hail. Moving water away from your building preserves the lifespan of the building and its envelope.
When should I replace my eavestroughs?
In Calgary, properly installed eavestroughs should last for 15–20 years. However, the lifespan of your eavestroughs can vary depending on how they were installed and the health of the fascia boards.
How do eavestroughs get damaged, and how can I protect them?
Calgary eavestroughs typically become damaged from hail storm impact, detaching from the home when overloaded with debris, warping from repeated freeze/thaw cycles, and bending due to wind. You can opt to have Alu-Rex leafguards installed, which catch debris and are rated to hold up to 250 lbs per linear foot.
What kind of eavestroughs does my home need?
Most eavestroughs in Calgary are either 5″ or 6″ wide. Roof types that need eavestroughs at least 6″ wide include tile, metal, wood shakes, and rubber. 5″ eavestroughs work for homes with regular asphalt laminate shingles, though many homeowners choose 6″ anyway because they carry nearly twice as much water and generally look better.
How long will my eavestrough installation take?
Our turnaround time for installing new eavestroughs on most homes is about 3 days from the time we give you your quote to the time we complete the job. We source materials locally and measure, cut, and install on-site, eliminating manufacturer delays.
Should I install eavestroughs myself?
We don’t recommend it. DIY eavestroughs must be purchased in sections with pre-set lengths, leaving numerous seams and points of failure. They also don’t look as good. And you won’t benefit from any installation warranty; Big 5 offers a 5-year installation warranty plus a 50-year manufacturer’s materials warranty.
How often should I clean my eavestroughs?
We recommend most homeowners clean their eavestroughs at least once a year, ideally in the fall. Note: We do not offer eavestrough cleaning services. Homeowners with Alu-Rex leaf guards installed will likely never need to clean their gutters at all.
Should you paint your eavestroughs?
You can paint your eavestroughs, but you really shouldn’t. Eaves can come in many colours and be colour-matched to your application. We’ll help you with colour selection. The paint is unlikely to adhere well to aluminum, and there’s a good chance you’ll accidentally wind up painting your fascia, soffit, and siding as well.
