Don’t let Minnesota’s moderate summers fool you. Though they’re a great reprieve from our chilly winters—when it comes to our homes—summers bring weather that can wreck your roof
Minnesota is renowned for its pleasant, summer weather, but the summer months actually account for almost half of its yearly rainfall. With so much rain confined to one season, homeowners need a properly installed roof that can easily shed water. A damaged or poorly installed roof won’t be up to the task of moving several inches of water away from the house, harming not just the roof but even the foundation of the home.
The sources of Minnesota’s mild, summer temperatures are Lake Superior and polar winds. The lake keeps things warm and humid while the winds from the north cool things off. But when they meet, they generate hail-producing storms. Shingles are rated on a scale of 1 to 4 for their ability to withstand impacts from storm-borne objects like hail, with 1 being the least resistant and 4 being the most resistant. Class 4 shingles are expected to withstand the impact of a 2” steel ball dropped from 20 feet. That’s about 16% larger than a golf ball—much bigger than most hail—but even the class 1 shingles can endure impacts exceeding Minnesota’s typical hail.
Beyond damaging rain and hail, Minnesota’s summer storms also produce high winds, even tornadoes. As with impact resistant shingles, roofing manufacturers also produce wind-resistant shingles. However, according to the Insurance Institute for Business and Home Safety (IHBS), shingle construction is only part of the solution when it comes to protecting your roof from damaging winds. Their research found that the key factor in a shingle’s wind resistance was dependent on the quality of the seal between shingle layers. Shingles which maintained that seal performed much better both in specific weather events and over time.
While a shingle’s material quality is important, its installation is even more important. A lower quality shingle properly installed will offer far more protection for the home than a higher quality shingle poorly installed. If a roof isn’t installed properly, it’s vulnerable to rain, hail, and wind, risking not just the roof, but the entire house.

Minnesota winters are well known for heavy snowfall, freezing rain, and frigid temperatures. Your home and particularly your roof should be well designed in order to protect you and your family from nature’s harsh temperatures and winter storms. A well-designed shingle roof that has been installed properly will protect your home from many winter hazards.
What are some of the Minnesota winter hazards and how does a new shingle roof protect your home from them?
A light blanket of snow on your roof can be a beneficial insulation to the cold temperatures, however, once the snow begins to accumulate, the weight of snow can be a hazard and cause a roof to sink or leak. There is also the risk of wind creating a heavy snow pile in one main area of your roof. A properly installed shingle roof will help evenly distribute snow in the winter, allowing the weight to be more spread out along the shingles. This will minimize the risk of damage.
- Freezing Rain
Minnesota winter weather can produce freezing rain. It will create a thick layer of ice on everything including your roof and the trees around your home. Inches can accumulate overnight and without proper ventilation and insulation could remain for days. This will increase the chance of ice dams and roof damage.
- Ice Dams
As the rain falls and freezes it can create ice dams. Ice dams are the accumulation of ice at the edge of your roof, subsequently preventing water from falling past. Those beautiful icicles along the eve of your home are the beginning of an ice dam. When a shingle roof is installed properly it will have the correct ventilation and insulation to prevent the build-up of ice. This is because it maintains a stable attic temperature and creates enough warmth to keep the ice melting. It is also a good idea to have your gutters and roof inspected before winter beings to prevent damage from ice build up.
Proper maintenance and annual inspections by a professional roofing contractor are critical to helping maintain the integrity of your roof.
