Understanding Calgary’s Winter Challenges
Calgary’s winters are famous for their unpredictable and severe conditions, posing special challenges for commercial roofing systems. Whether it’s severe temperature changes, excessive snow accumulation, or the ongoing freeze-thaw cycle, these constant challenges can take a toll on many roofing products.
Calgary’s geographic and climatic conditions require vigilant foresight, design and upkeep to deliver durable, lasting safeguards.
How Calgary’s Winters Impact Commercial Roofs
Ice dams present the biggest threat to Calgary roofs in winter. This occurs when snow melts and then refreezes at the edge of the roof, creating an ice dam that stops water from draining off the roof. This stagnant water tends to work its way into roofing materials, increasing the risk of leaks and damage within the building.
Drastic temperature swings lead to thermal contraction and expansion. This can quickly develop into cracks and compromised seams which can leave roofs susceptible to water penetration.
The same issue comes up with snow accumulation. That additional weight can put severe strain on the roof’s structure, leading to sagging or even the risk of a collapse. Rapidly oscillating temperatures only compound this problem. They tend to create conditions where snow melts and immediately refreezes, creating additional stress both on the roof surface and on drainage systems.
Unique Weather Patterns and Their Effects on Roofs
Calgary’s chinooks, warm winds that cause drastic temperature shifts, can cause roof membranes to become brittle and fail over time. These temperature swings can lead to over-expansion and contraction of materials and greatly shorten their life.
The high winds in Calgary’s storms not only tear off shingles but also cause damage to flashing and other roof components, resulting in roofs being exposed to potential damage. Extended periods of snowfall can exceed drainage systems, leading to ponding water that speeds up material degradation.
Common Winter-Related Roofing Issues in Calgary
Ice dams, ponding water, and leaks are all common issues during Calgary’s long winters. Poor insulation only makes these problems worse – when heat escapes from the roof, it causes snow to melt and refreeze.
Blocked gutters and downspouts mean that water can pool, and overloaded roof snow can cause catastrophic structural failure. Preventative measures like regular inspections and snow removal are essential in managing these risks.

Why Winterproofing is Essential for Calgary Roofs
Winterproofing a commercial roof is more than just a best practice—it’s a necessity. Calgary roofs deserve this small extra step—it’s an investment in durability, long-term energy efficiency, and savings!
Calgary’s harsh winters, characterized by heavy snow, freezing temperatures, and sudden thaws, can take a toll on roofing systems, making proactive preparation vital.
Preventing Ice Dams and Thermal Cracking
Ice dams form when heat escapes through the roof, melting snow that refreezes as ice at the edges. With proper insulation, heat transfer is minimized, allowing the roof surface to stay cold and preventing this cycle.
Sealing penetrations, such as vent stacks and skylights, prevent thermal cracking from cyclical temperature changes from occurring. Good ventilation is equally important, helping to maintain consistent attic temperatures and prevent moisture accumulation.
To prevent ice dams:
-
Ensure adequate attic insulation.
-
Seal gaps around roof penetrations.
-
Install roof and soffit vents.
-
Clear gutters of debris before winter.
Avoiding Ponding Water and Leaks
Ponding water is a major concern for flat roofs, especially following a snowmelt. Ensuring your drainage systems are in working order will help keep water from pooling on your roof, causing serious leaks.
Regular inspections can help to identify weak spots, while membrane sealing can provide your home with extra protection. Once ponding water has frozen, any additional stress on the structure may result in even more severe damage.
Extending Roof Lifespan Through Proactive Maintenance
In addition, minor issues such as small cracks, loose flashing, etc., deteriorate greatly over time. The longer these issues are left untreated, the more noticeable they will become and the more expensive they will be to repair.
Winterproofing techniques using durable materials engineered to withstand Calgary’s winters, like reinforced membranes, protect snow loads and freeze-thaw cycles.
Enhancing Energy Efficiency During Harsh Winters
Adequate insulation can reduce heating expenses by as much as 40%! Reflective coatings help to keep temperatures stable indoors, and energy-efficient materials such as EPDM and TPO roofing adapt well to icy or sweltering conditions.
The winter season brings several challenges for flat commercial roofs:
-
❄️ Freeze-thaw cycles that crack membranes and split seams
-
❄️ Heavy snow loads that stress structures and cause ponding when melting
-
❄️ Ice dams that block drains and force water under flashings
-
❄️ Cold weather shrinkage that causes gaps in EPDM or torch-on membranes
-
❄️ Clogged scuppers and downspouts that trap water and cause leaks
Without proper winterproofing, your building is vulnerable to water intrusion, mold, insulation damage, and even structural decay.
Our Commercial Roof Winterproofing Services
Year-round services for winterproofing commercial roofs in Calgary Calgary are known for their tough winters, and your roofing strategy should be no different. Flat roofs versus sloped roofs—each roof type has different challenges, which is why customized solutions are key.
A comprehensive inspection Roof winterization begins with a comprehensive inspection, pinpointing roof damage, structural weaknesses, and other premature weaknesses that could lead to leaks. By using a combination of services, companies will be able to guarantee complete protection from nasty winter dangers such as snow, ice, and frigid temperatures.
1. Snow Load Preparation and Management
Flat roofs, which are very frequent in the commercial building world, need to support heavy snow loads. Being able to calculate snow load capacity is important to avoid undue structural stress or even collapse.
Snow guards are usually best installed to minimize hazardous avalanches in sloped areas. Keeping the snow load managed with professional equipment, such as roof rakes and snow blowers, protects your building from potential collapse and prevents water ponding.
By engaging in proactive snow management, you reduce risk and prolong the life of your roof.
2. Insulation Checks and Upgrades
Inadequate insulation can lead to energy waste and ice dams. Quality roofing and insulation materials not only ensure that heat is retained, lowering energy costs, but they also prevent moisture buildup.
Improvements to attic insulation and ventilation not only keep interiors comfy during winter months, but they safeguard the roof’s structural integrity from damaging shifts in temperature extremes.
3. Membrane Sealing for Leak Prevention
Membrane sealing is an essential service for preventing water intrusion. During inspections, particular attention is paid to seams and joints, which are where roofs are most prone to leaking.
Liquid-applied membranes provide a truly seamless solution, and their expert application will yield protection that can withstand Calgary’s harsh frostbite-inducing climate.
4. Flashing Repair to Prevent Water Intrusion
Flashing typically consists of metal sheeting that directs water away from vulnerable areas such as a chimney or vent. Loose or damaged flashing will only get worse as winter progresses, increasing the chances of a vastly more expensive repair.
High-quality materials and speedy repairs provide a lasting defense.
5. Drainage System Maintenance
Clogged gutters and downspouts will lead to blockages of ice and standing water forming on the roofing. Routine cleaning, installation of heated cables, and ensuring adequate slope (2%-4%) can help the roof drain water quickly during snow and ice events.
6. Heat Trace System Installation
Heat trace systems help to keep ice from building up in gutters and downspouts, minimizing the need for maintenance. Automated options deliver reliable performance, while expert installation delivers peace of mind.
We tailor every winterproofing job based on roof age, slope, material, and usage.
