Obviously, wind, rain, and hail cause storm damage to your residential or commercial roof. However, what can change is the severity of the damage. After all, small hail that only falls for a brief amount of time can cause very little damage overall. That being said, the kind of hail you have to worry about here in Northern Colorado is the large-sized hail that is very dense, meaning its thickness. As you probably know from your high school physics class, the longer objects fall, the more speed they gain, and the larger amount of impact they will have. Thus, large hail falling from the sky can do considerable damage to your home or office's roof.
