Minnesota is no stranger to extreme weather. Our winters are harsh, our summers carry high levels of humidity and severe storms, and wind can easily cause damage to a home. All of these factors can accelerate present construction defects, and as a homeowner, it is important that you understand how Minnesota weather affects construction defect claims. At Minnesota Construction Law Services, we are here to help.

Severe Weather in Minnesota and Its Effect on Construction Defect Claims

On average, Minnesota sees some form of precipitation 113 days out of the year, and while the southwest part of the state sees an average of 35 inches of snow a year, the northeast portion sees over 70 inches a year. Certain forms of weather have the ability to make a construction defect worse or highlight the defect in the first place. It is important to understand how the weather can affect these claims and whether the damage can be traced back to negligence. 

  1. Freeze/thaw cycles. In winter and spring, the freeze-thaw cycle of built-up snow can cause present construction defects to worsen. These cycles bring about ice dams, cracks in roofing and moisture intrusion, and can lead to claims regarding premature roof failure, damaged flashing or siding, and broken masonry. You may be able to trace the damage back to poor installation or sealing and file a construction defect claim.
  2. Moisture and high humidity. In the summer, high humidity levels can combine with poor or improper ventilation and cause hidden construction defects to show themselves. Improperly installed cladding or siding can also lead to moisture-related construction defect claims. When there is improper ventilation, moisture can lead to mold growth, wood rot, and a deterioration of the structure.
  3. Severe storms. Minnesota frequently experiences high winds and extreme levels of damaging hail in the summertime. This can cause subtle damage that can quickly expose construction defects in the roof, siding, or windows of a structure that might not have shown itself otherwise. However, legal disputes can arise over whether these issues were the direct cause of the weather or due to improper installation and negligence.
  4. Cold weather challenges. When construction occurs in cold weather, the low temperatures will require certain procedures to ensure the work is done correctly. When construction companies fail to follow these procedures, defects can occur. Certain adhesives, sealants, and roofing membranes, for example, might not cure properly in temperatures below 40°F, leading to weakened seams and potential leaks.

If you have recently experienced severe weather and believe the damage sustained is actually due to a construction defect, it is important that you reach out to an attorney who can protect you should you choose to file a claim. At Minnesota Construction Law Services, we are here to review your case and help determine the viability of a construction defect claim when it comes to severe weather damage in Minnesota.
