Climate change is no longer a distant concern—it’s something we experience in our daily lives. From intense storms to prolonged heat waves, these temperature extremes are increasingly influencing how we build and maintain our homes. In Manitoba, these changes are especially noticeable, given the province’s already extreme climate. With cold winters, hot summers, heavy snowfall, and fluctuating temperatures, homeowners need to be extra careful when it comes to the health of their roofs.
Roofs are your home’s first line of defence against the elements. Choosing resilient roofing solutions and climate responsive roofing materials that can withstand extreme weather conditions is crucial, especially as weather becomes more unpredictable. At Above All Roofing, we’ve made it our mission to help Manitobans safeguard their homes against extreme weather, and stay-on-top of how climate change on roofing affects and influences homeowners and decision making about their roofs.
How Manitoba’s Weather Affects Roofs
Cold Winters & Roof Durability
Manitoba is infamous for its bitterly cold winters. Temperatures can drop far below freezing, often for weeks at a time. But the cold alone isn’t what damages roofs—it’s the freeze-thaw cycles that can take a toll. As temperatures fluctuate, water trapped on your roof can freeze and then melt repeatedly, causing cracks and damage over time.
Ice dams are another significant concern during these cold spells. When heat escapes from your home, it can melt snow on the roof, which then refreezes at the edge, creating ice dams. These ice dams prevent proper drainage and can lead to leaks and further roof damage if not addressed.
Heatwaves and Sun Damage
While Manitoba is known for its frigid winters, it also experiences scorching summers. The UV radiation and high temperatures during these periods can lead to sun damage, which affects the durability of roofing materials. Shingles may crack, warp, or degrade due to long-term exposure to the sun. Roofs made from metal or other materials are also susceptible to expansion and contraction in extreme heat, which can cause stress on the roof structure.
Heavy Rain and Storms
Manitoba’s stormy weather is becoming more intense due to climate change. As rainfall increases in frequency and intensity, roofs are exposed to additional stress. Heavy rain can exacerbate small leaks or imperfections, while strong winds during storms can dislodge shingles or cause flashing to loosen. As storm patterns become more erratic, your roof needs to be in top condition to withstand these forces, or you may face costly repairs down the road.
Increased Wildfire Risk
Rising temperatures and worsening drought conditions increase the threat of wildfires, especially in areas with dry vegetation and high winds. Roofs made of combustible materials like wood shakes or asphalt shingles are particularly vulnerable to fire damage, making fire-resistant roofing materials more important than ever for Winnipeg homeowners.
The Changing Weather Patterns in Manitoba
Overview of Climate Changes
The scientific consensus is clear—climate change is contributing to more extreme weather events and unpredictable weather patterns. For Manitoba, this means not only harsher winters and hotter summers but also more frequent storms and rainfall events. For homeowners, it’s essential to recognize that these changing patterns will continue to stress roofing systems in ways we haven’t seen before.
Statistics from climate experts show a rise in temperature fluctuations, which can weaken the structural integrity of homes over time. Sudden storms and flash flooding have also become more common, particularly during warmer months. These climate shifts are creating new challenges for traditional roofing materials, maintenance, and protection, requiring more resilient solutions to keep your home safe.
Future Weather Projections
Looking ahead, Manitoba is expected to face even more significant changes in weather patterns. Scientists predict more intense heat waves, heavier rainfall, and longer winter seasons with stronger cold snaps. This means that homeowners will need to adjust their roofing strategies accordingly. By preparing for these future trends today, you can minimize potential damage and ensure your home remains safe and well-protected, no matter what Mother Nature throws your way.

Choosing the Right Roofing Materials
Selecting the best roofing materials for Manitoba’s changing climate is essential to ensure long-term durability and protection. With unpredictable weather patterns becoming the norm, homeowners need to consider sustainable roofing solutions and materials that not only offer resilience but also improve energy efficiency and sustainability. Here are some key options to consider:
Impact-Resistant Materials
Manitoba’s extreme weather, including hailstorms and high winds, can wreak havoc on roofs. Impact-resistant materials are designed to withstand such harsh conditions.
- Composite Shingles: Materials like Euroshield, made from recycled rubber, are highly impact-resistant and offer long-lasting protection.
- Metal Roofing: Known for its durability, metal roofing can resist dents and damage from hail and debris, making it ideal for areas prone to strong storms.
- Class 4 Shingles: These shingles have been tested to withstand high impact and provide superior protection against weather damage.
Advanced Drainage Solutions
Proper drainage is crucial to prevent water damage, especially during Manitoba’s heavy rainfalls and melting snow periods.
- Gutter systems: High-quality gutter systems that channel water away from your home can prevent leaks and water accumulation on your roof.
- Slope adjustments: Ensuring your roof has an appropriate slope for proper water runoff can reduce the risk of water pooling and structural damage.
- Ice dam prevention: Installing heating cables or improving insulation can prevent ice dams from forming, protecting your roof from winter water damage.
Improved Design and Construction Practices
Architects and builders are increasingly incorporating climate-resilient design principles to better protect homes from extreme weather events.
- Proper roof slope and drainage: Ensures effective water runoff, reducing the risk of water pooling and leaks.
- Enhanced wind uplift resistance: Strengthening roof structures to withstand strong winds and prevent shingle or material displacement during storms.
- Strategic placement of roof overhangs and shading devices: Helps reduce sun exposure and heat absorption, while providing additional protection from rain and snow.
Cool Roofing Technologies
With Manitoba’s hot summers, reducing heat absorption can help lower cooling costs and improve home comfort. Enter cool roofing technologies. A cool roof is a roofing system designed with a coloured membrane or coating that reflects a significant amount of sunlight. Unlike traditional dark roofs, it efficiently releases any absorbed heat, keeping the roof cooler and reducing heat buildup.
- Reflective coatings: Applied to shingles or metal roofs, these coatings help reduce the amount of heat absorbed by your roof.
- Light-colored materials: Opting for lighter-colored shingles or tiles can naturally reflect more sunlight, keeping your home cooler during heatwaves.
- Energy-efficient roofing systems: Installing cool roofing materials can reduce energy consumption and lower utility bills, especially in the summer months.
Importance of Roof Maintenance
No matter what type of roof you have, proactive maintenance and regular roof inspections are crucial for optimal performance and prolonging its lifespan. At Above All Roofing, we recommend annual roof inspections, especially in Manitoba where our weather is so varied. Regular maintenance helps prevent costly repairs and allows you to spot potential issues, such as damaged shingles or drainage problems, before they escalate.
Ice dam prevention, gutter cleaning, and sealing up any small gaps or cracks are just a few of the ways you can maintain your roof. Our experience has shown that a well-maintained roof is far more likely to hold up against the wear and tear of changing Winnipeg weather.
How to Protect Your Roof Against Future Climate Challenges
As weather patterns continue to shift, it’s more important than ever to prepare your roof for the unexpected. At Above All Roofing, we recommend investing in energy-efficient materials that help regulate temperature inside the home while also being resilient against extreme heat and cold.
Adequate insulation and proper ventilation is key to preventing heat loss in the winter, which will reduce the likelihood of ice dams forming. Additionally, installing proper drainage systems can help manage heavy rain during severe storms, minimizing the risk of water damage.
