When Ontario winters bring freezing temperatures and heavy snow, your home’s gutter and downpipe system is regularly exposed to the extreme conditions. While most homeowners focus on insulating pipes or sealing windows, the downpipe — also known as the downspout — is often forgotten. Nevertheless, this component is responsible for ensuring proper drainage, and if the downpipe is not winterproof, ice dams can flood your home, leading to cracks, leaks, and water damage to the siding and foundation.
Ontario Siding & Gutters is well aware that preparing the drainage system for winter is the key to affordability and effective functioning in the future.
1. Understand How Ice Dams Form
An ice dam forms when snow melting off your roof refreezes at its edge, preventing water from draining properly. The water trapped there then backs up under shingles or leaks into downspouts, where it freezes anew. This process can cause your downpipes to crack and joints to split, or even cause them to burst due to the pressure from the ice that forms in them.
Tip: Clean out your gutters and downspouts before the first snow. Even small debris can hold water and initiate freezing.
2. Inspect and Clean Before the Freeze
You can avoid a lot of hassle with an easy pre-winter inspection. Check for leaves, twigs and dirt accumulations in the gutters and downpipes. These blockages can cause a water back-up and provide the ideal conditions for ice to form.
Pro Tip: Get out the gutter scoop or step up (or hire someone) to give gutters a complete flush and inspection before temperatures plummet.
3. Install Downpipe Heating Cables
Downspout heating cables or heat-trace systems are among the best methods for preventing downspouts from freezing. These cables run inside or outside your gutters and downpipes, gently warming them to prevent freezing.
Not only do they minimize ice buildup, but they also prolong the life of your drainage system by eliminating ice-expansion cracks.
4. Insulate Exposed Downpipes
If your downpipes run along outside walls or cold spaces, insulating them can have a massive impact. Foam pipe insulation or thermal wraps create a shield against frigid air and help keep water moving in sub-zero temperatures.
Insulate snugly and weather-resistantly, especially at joints or bends where cracks often form.
5. Check for Proper Slope and Drainage
If the downpipes don’t have a proper slope, they will block water rather than funnel it away from your home. This water freezes, forming ice dams that make your roof more vulnerable to stress cracks.
A correctly sloped downpipe ensures that thaw water evacuates quickly and thoroughly. If you ever see water pooling or draining slowly, it may indicate that your system needs adjustment or even replacement.
6. Consider Seamless Aluminum Downspouts
Seamless downpipes are the perfect replacement for Ontario homes, as they eliminate weak points where ice and leaks are most likely to occur. Aluminum is low-maintenance, rust-resistant, and ideal for cold weather, so that you can feel confident in your investment.
At Ontario Siding & Gutters, we install premium-quality seamless systems guaranteed to last – even during winter months when temperatures drop in Canada.
7. Schedule a Professional Winter Inspection
You may never know it, despite how well you maintain your water heater. A professional inspection delivers peace of mind that every joint, seal, and connection is secure, and that your entire drainage system is poised for winter.
With Ontario’s weather in mind, Ontario Siding & Gutters’ team offers seasonal maintenance and inspections to help homeowners maintain peace of mind before the snow falls.
