For homeowners, this means selecting roofing materials that can withstand this spectrum of weather conditions. One of the popular choices in recent years has been metal roofing.

Understanding Metal Roofs

Metal roofs, once primarily associated with commercial buildings or barns, have found a growing fanbase among residential homeowners. Their appeal lies in their durability, energy efficiency, and modern aesthetics. They are also prized for their fire resistance and ability to shed snow quickly, a significant advantage in snowy states like Minnesota.

Varieties of Metal Roofing

Not all metal roofs are created equal. The primary types include steel, aluminum, copper, and zinc. While all these materials have their unique strengths and aesthetics, steel and aluminum are particularly favored in Minnesota due to their resistance to rust and corrosion.

The Minnesota Factor: Regional Impact on Roof Longevity

Challenging Weather Conditions

Minnesota’s climate plays a vital role in determining the longevity of any roofing material. With snowy winters, potential for hail, and the occasional summer heatwave, a roof installed in Minnesota certainly has its work cut out for it. Fortunately, metal roofs are known for their resilience in diverse weather conditions.


Given the state’s humidity, especially during summers, there’s a potential for corrosion. This is particularly true if you live near one of the many lakes, where moisture levels might be higher. While metal roofs are treated to resist rust, the risk, though minimal, cannot be entirely ruled out.

So, How Long Do Metal Roofs Last in Minnesota?

On average, metal roofs can last anywhere between 40 to 70 years, depending on the material and maintenance. In the context of Minnesota, with its specific climatic challenges, homeowners can expect a well-maintained metal roof to serve them for at least 50 years, if not more.

However, as with any home component, the longevity of metal roofs in Minnesota is also tied to maintenance. Regular checks, cleaning off debris, ensuring fasteners are in place, and checking for potential rust spots can ensure that the roof lasts its intended lifespan, if not longer.

Protective Coatings and Treatments

Applying protective coatings can safeguard your roof against the elements. Such treatments can provide an extra layer of defense against potential rust or corrosion, especially in the humid months.

Snow Removal (with Caution!)

While metal roofs are excellent at shedding snow, in cases of heavy snowfall, it might be prudent to remove excess snow. However, it’s essential to do this carefully to avoid scratching or damaging the roof’s surface.

Professional Inspections

Scheduling periodic professional inspections can help in early detection of any issues. Experts can spot potential problems that might escape the untrained eye and recommend timely interventions.
