Minnesota Weather & Its Impact on Commercial Flat Roofing Systems

At Wheeler Construction, we've spent over a decade helping property managers and business owners across the Twin Cities metro area protect their commercial roofing systems from Minnesota's intense, often unpredictable weather. 

From cold, snowy winters to scorching summers, the state's climate poses unique challenges for flat roofing systems. Addressing these challenges early can make all the difference in extending the lifespan of your roof and protecting your property.

Whether you're managing a commercial building or running your own business, understanding Minnesota’s climate and its effects on flat roofs is vital. 

Below, we'll explore the specific challenges posed by our weather, common vulnerabilities of flat roofing systems, and key strategies to ensure long-term durability and performance — all informed by our extensive experience.

How Minnesota's Weather Affects Flat Roofs 

Minnesota's weather swings are infamous, varying dramatically between seasons — sometimes even within a single day. For your commercial flat roof, these fluctuations aren’t just inconvenient; they can cause serious structural and material issues if left unaddressed. 

Here’s a closer look at the major weather-related stressors and their impact.

1. Heavy Snow & Ice Accumulation

Minnesota winters bring significant snowfall, and accumulation on flat roofs can lead to major problems if not managed properly. 

Snow that doesn't melt or drain efficiently adds unnecessary weight, potentially straining the roof's structure. When the snow melts and refreezes, it forms ice dams along roof edges, trapping water and increasing the risk of leaks.

Our recommendation: Wheeler Construction emphasizes professional snow and ice removal services to prevent damage while safeguarding workers and the property.

2. Ice Formation From Freezing Rain 

Freezing rain coats roofs, gutters, and HVAC equipment with a heavy layer of ice, creating stress points and reducing overall efficiency. 

This is particularly problematic for drainage systems on flat roofs, where standing water may collect if the drain is obstructed by ice. Over time, water seepage into the roof can cause cracks and compromise the roof's integrity.

Our solution: We recommend installing fully functional ice and water shields in these vulnerable areas to prevent infiltration and long-term damage.

3. Extreme Temperature Fluctuations 

One of the biggest culprits behind Minnesota roofing damage is the rapid shift in temperatures — what we call freeze-thaw cycles. These constant expansions and contractions of materials stress roof seams and joints, weakening adhesives or causing cracks in membranes over time.

How we help: At Wheeler Construction, we utilize premium-quality, weather-resistant materials designed to withstand thermal movement, providing your roof with the flexibility it needs to endure these repeated changes.

4. Harsh UV Exposure & Severe Summer Storms 

Though winter is tough, Minnesota summers also test flat roofing systems. 

UV rays from the sun can degrade materials, particularly older roofing membranes, such as asphalt and built-up roofing systems. Meanwhile, summer thunderstorms, complete with heavy rains and strong winds, can wreak havoc by loosening fasteners or tearing membranes.

With Wheeler Construction: Regular inspections during and after severe weather events ensure these issues are caught early, offering peace of mind for property managers and business owners alike.

Protect Your Investment With Proactive Roofing Maintenance

Based on our years of experience, we believe that proactive maintenance is key to preserving your roof's optimal performance. Minnesota weather might be harsh, but these proven strategies can minimize damage and extend your roof's lifespan. 

Here’s how you can stay ahead of the elements:

1. Schedule Regular Inspections 

Routine roof inspections — at least twice a year — are crucial for identifying potential problems, such as drainage issues or material fatigue, before they escalate. Major weather events, such as hailstorms or blizzards, require more immediate assessments to check for hidden damage.

What sets Wheeler apart: We combine thorough visual inspections with high-tech solutions, such as infrared imaging, to detect leaks or weak points that are invisible to the naked eye. Additionally, we provide 24/7 emergency leak repair for when you need immediate assistance. 

2. Invest in Professional Snow Removal 

For flat roofing systems, letting snow accumulate unchecked is a recipe for disaster. Heavy snow can create structural strain, while ice dams lead to leaks in insulation or interior spaces.

Why choose us: Wheeler Construction provides safe, efficient snow and ice removal, preventing damage while avoiding accidental harm to your roof during the process.

3. Use High-Quality Roofing Materials 

Not all roofing materials are equal. The most effective systems for Minnesota's climate resist water damage, endure freeze-thaw cycles, and stand up to heavy winds. 

At Wheeler Construction, we recommend durable options like EPDM membranes and modified bitumen for long-lasting results. 

4. Properly Maintain Your Drainage System 

Standing water is a flat roof’s worst enemy, especially when combined with clogged drains or gutters. Regular cleanings are essential to ensure that water is directed off your roof and away from the building's foundation.

Our expertise: We go beyond basic cleanings — we can inspect and upgrade your drainage system for superior performance in snowmelt and heavy rain.

5. Reinforce Vulnerable Areas 

Flat roofing systems have inherent weaknesses, including seams, flashings, and HVAC openings. These areas are often the first to show damage from extreme weather.

Extra protection with Wheeler: We proactively strengthen these areas with weatherproof coatings, advanced adhesives, and additional sealing to prevent water infiltration.
