As Calgary-based roofing experts, we know that weather is anything but predictable. The climate can be a true test for your roof, from blistering summer heat to harsh winter snowstorms. Understanding how weather conditions impact roofing materials is crucial for homeowners and commercial property managers.
At City Roofing & Exteriors, we’ve seen firsthand how the elements can wear down even the most robust roofs. This guide will walk you through what you need to know to keep your roof in top condition, no matter what Mother Nature throws your way.
Summer Heat
Intense summer heat can cause roofing materials to expand and contract, potentially leading to cracks, warping, and deterioration. Asphalt shingles, common for many roofs, may become brittle under extreme heat, reducing their effectiveness and lifespan. In contrast, metal roofs handle heat better due to their reflective properties, which help deflect sunlight and keep your home cooler.
What you can do: Consider investing in reflective coatings or light-coloured roofing materials to reduce heat absorption and extend the life of your roof.
Dealing with Winter Conditions
With its freezing temperatures and snow, winter weather can be tough on your roof. Ice dams, which form when snow melts and refreezes at the roof’s edge, can lead to water infiltration and damage. Materials like asphalt shingles may suffer from thermal shock as they contract in the cold, causing potential cracks and leaks.
What you can do: Ensure your roof has adequate insulation and ventilation to prevent ice dams. Regular roof inspections before winter can help catch any potential issues early.
Handling Wind Exposure
Strong winds can seriously threaten your roof by lifting shingles, tiles, or panels, leading to water damage and structural issues. Over time, repeated wind exposure can weaken your roof’s integrity.
What you can do: Choose wind-resistant materials like metal or architectural shingles designed to withstand high winds. Regular maintenance and prompt repairs are key to keeping your roof secure.
Rain and Hail
Frequent rain and occasional hail can cause significant damage if your roof isn’t up to standard. Persistent rain can lead to water infiltration, especially if there are existing issues. Strong winds can seriously threaten your roof by lifting shingles, tiles, or panels, leading to water damage and structural problems. Over time, repeated wind exposure can weaken your roof’s integrity.
What you can do: Regularly check your roof for signs of damage, especially after a storm. Consider materials like impact-resistant shingles or metal roofing, which offer better protection against hail.
Choosing the Right Roofing Material
Selecting the right roofing material involves considering how it will perform under various weather conditions. No roofing material is completely weather-proof, but some are better suited for different climates.
- Durability: Opt for materials that can handle temperature extremes and varying weather conditions. Metal roofing and high-quality asphalt shingles with impact resistance are good options.
- Maintenance: Some materials require more upkeep, while others require less maintenance. For example, wood might need more care in wet climates, whereas slate or metal typically requires less frequent maintenance.
- Aesthetics vs. Practicality: Balance the look of the roofing material with its practicality. Ensure it complements your home’s design and performs well in specific weather conditions.

Weather could be as varied as it is challenging, but with the right roofing materials and maintenance, you can keep your roof in great shape year-round.
