As the owner or manager of a commercial building in Calgary, it’s your duty to ensure everything is in perfect condition. The roof of your commercial building is an important structure. And sometimes, it may run into a few unexpected problems. Below, we will be discussing the common commercial roof problems in Calgary. Our goal is to educate you on what issues you may run into and how you can best resolve them. 

7 Common Commercial Roof Problems in Calgary

1. Weather-related Damage

This beautiful city is no stranger to extreme weather conditions. During the winter months, heavy snow and ice accumulation can lead to added weight and strain on commercial roofs. When the snow melts and refreezes, it can cause ice dams, potentially damaging the roof’s structural integrity and leading to leaks.

2. Leaks and Water Damage

Leaking roofs are a common issue in commercial buildings, and Calgary is no exception. Water can seep into the roofing structure, causing extensive damage over time. The freeze-thaw cycle prevalent in the city can exacerbate these problems, as the water expands when frozen, it widens any existing gaps and cracks in the roof.

3. Poor Installation and Maintenance

Improper installation and inadequate maintenance are fundamental problems that affect commercial roofs in Calgary. When a roof is not installed correctly or is not maintained regularly, it can result in premature deterioration and reduced longevity. Routine inspections and timely repairs are crucial in extending the life of the roof and preventing potential issues.

4. UV Exposure

Calgary sees a significant amount of sunlight throughout the year. Prolonged exposure to UV rays can degrade roofing materials, leading to cracks, brittleness, and discoloration. UV damage weakens the roof’s ability to protect the building effectively and can accelerate the need for repairs or replacement.

5. Blow-offs and Wind Damage

Calgary also experiences occasional strong winds, especially during certain seasons. High winds can lift and detach roofing materials, leaving the roof vulnerable to further damage and leaks. Properly securing the roofing components during installation and conducting regular maintenance can mitigate the risk of blow-offs.

6. Aging and Deterioration

As commercial roofs age, they naturally deteriorate due to wear and tear. The harsh Calgary weather accelerates this process, making older roofs more susceptible to leaks, cracks, and other structural issues. Regular roof inspections can help identify signs of aging and allow for timely repairs or replacement.

7. Drainage Problems

Proper drainage is crucial for any roof, and Calgary’s climate underscores its importance. Snow and ice can block gutters and drainage systems, preventing proper water flow. This accumulation can lead to standing water, adding unnecessary weight and increasing the risk of leaks and structural damage.

What Types of Commercial Roofs Are More Vulnerable to These Problems?

When examining the most common commercial roof problems in Calgary, it’s important to recognize that different roofing materials and styles have varying vulnerabilities. Certain roof types are more prone to specific issues due to their design, materials, or age. Let’s discuss which commercial roof types are particularly susceptible to the prevalent problems listed above. 

1. Flat Roofs

Flat roofs, commonly used in commercial buildings, are especially susceptible to weather-related issues. The lack of a natural slope hinders water drainage, making them prone to water accumulation during heavy rains or snowmelt. This accumulation can lead to leaks and water damage over time.

Proper drainage is also another problem for flat roofs. The absence of a significant slope makes it easier for snow and ice to obstruct drainage systems, causing standing water. This standing water increases the risk of structural damage and accelerates the aging process of the roof.

2. Asphalt Built-Up Roofs (BUR)

BUR roofs, made of layers of asphalt and reinforcing fabric, are susceptible to UV exposure. The asphalt can degrade over time due to the sun’s rays, causing the roof to become brittle and more prone to cracks and leaks.

Asphalt-based roofing materials, like those in BUR systems, age relatively quickly. Calgary’s extreme temperature variations can speed up the aging process, resulting in premature deterioration and the need for frequent repairs or replacement.

3. EPDM (Ethylene Propylene Diene Monomer) Roofs

While EPDM roofs are durable and can withstand a range of weather conditions, severe hailstorms common in Calgary can cause punctures and tears in the membrane, leading to leaks and water infiltration.

EPDM roofs may experience premature aging in Calgary’s intense sunlight and rapidly changing weather. Over time, the material can become less flexible, making it more susceptible to damage from hail and other impacts.

4. Metal Roofs

Metal roofs, while generally resilient, can experience issues related to UV exposure. Prolonged sun exposure can cause the metal to expand and contract, potentially leading to seam separations, leaks, and overall weakening of the roof’s structure.

If not properly installed and maintained, can be susceptible to blow-offs during strong winds. Improperly secured metal panels can lift, creating openings that compromise the roof’s integrity.
