Because hail damaged windows are hard to spot, many homeowners will not know their windows are damaged until it is too late, and the window has failed. Often times, after a hailstorm, the inspector or contractor is focused on other parts of your home like your roof and they miss the damage to your windows. Left unchecked, hail damaged windows fail over time. The results can be drafty windows, foggy glass, hard to open windows, and even black staining on the interior wood trim.
