The Impact of Michigan’s Weather on Commercial Roofing Systems

Michigan’s weather is notoriously unpredictable, with its intense winters, strong winds, and occasional hailstorms. These fluctuating conditions present unique challenges to commercial roofing systems. Understanding how Michigan’s climate impacts your roof is essential for prolonging its lifespan and ensuring the safety of your business. In this blog, we’ll explore how different weather elements affect commercial roofs and what steps can be taken to protect them.

The Challenges of Michigan Weather

1. Snow and Ice Damage
Michigan winters are brutal, with heavy snowfall and frequent freezing temperatures. The accumulation of snow on commercial roofs can be particularly damaging, especially for flat roofs commonly found on industrial buildings. The weight of the snow can cause sagging, and ice dams may form, preventing proper drainage. Ice dams lead to water backing up under the roofing materials, causing leaks and potential structural damage.

2. Freeze-Thaw Cycles
Michigan often experiences fluctuating temperatures in winter, causing snow and ice to melt and refreeze repeatedly. This freeze-thaw cycle leads to cracks in roofing materials, especially in seams, joints, and around flashing. Over time, these cracks can worsen, creating vulnerabilities that allow water to seep through the roof.

3. High Winds and Storm Damage
In addition to winter weather, Michigan is known for powerful winds and storms throughout the year. High winds can loosen or rip off roofing materials, leaving the underlying structure exposed to the elements. Roofs on taller commercial buildings are particularly susceptible to wind uplift, where strong gusts lift the edges of the roof, potentially leading to major damage.

4. Hail Impact
Hailstorms can occur during Michigan’s spring and summer seasons, and they pose a significant risk to commercial roofs. Hail can dent or puncture roofing materials, especially if the roof is made of metal or membrane roofing. Even small impacts can weaken the roof’s integrity, causing long-term issues like leaks or insulation damage.

How to Protect Commercial Roofs from Michigan’s Weather

To withstand Michigan’s extreme weather conditions, it’s important to take preventive measures and use the right materials. Here are some strategies to protect your commercial roof:

1. Regular Inspections
Scheduling regular roof inspections, particularly after harsh weather, can help identify and address issues before they worsen. Professional roofers can spot small cracks, damaged flashing, or other problems caused by the freeze-thaw cycle and repair them before they become major issues.

2. Proper Drainage Systems
Ensuring your roof has an effective drainage system is crucial for preventing water damage, especially in winter when ice dams can form. Installing additional drains or heated cables in areas prone to ice buildup can help keep water flowing and reduce the risk of leaks.

3. Investing in Durable Roofing Materials
Choosing roofing materials that are designed to withstand Michigan’s climate is essential. For example, EPDM rubber roofing is resistant to UV rays and temperature fluctuations, while TPO roofing offers excellent energy efficiency and durability against hail and wind.

4. Strengthening Roof Edges
Since wind uplift often occurs at the edges of the roof, reinforcing these areas with proper flashing and fasteners can reduce the risk of wind damage. Make sure that your roofing contractor is using high-quality materials that are specifically designed for high-wind areas.

In conclusion, Michigan’s extreme weather can have a major impact on commercial roofing systems, from the freeze-thaw cycle to strong winds and hail. By investing in regular maintenance, proper drainage, and durable materials, you can protect your roof from the harsh elements and ensure it lasts for years to come. Whether you need a repair after a storm or a complete roof replacement, working with an experienced roofing contractor will help safeguard your commercial property.
