Pole barns are a popular choice for many farmers and ranchers in Michigan thanks to their cost-effectiveness and easy construction. They are made from a series of poles that run across the entire building length, with one end in contact with the ground and the other in contact with the ridge beam. The ridge beam is raised off the ground at least 8 feet, which creates an air gap that allows for water drainage. However, if the roof of your pole barn is damaged, it can lead to leaks, damage, and pest infestations.
