Windows and Doors
A common problem with large barns is damaged window glass in the gable end windows. They are often over 20 feet above the barn floor and broken glass is left unrepaired allowing rain water and snow to enter. Over time this rots out the principle tie beam in the end wall. Replacing a broken gable end window as soon as it gets broken can easily save thousands of dollars in structural repairs later. Leaking ventilators and doors cause similar problems in other areas of the barn. The main doors to the drive bay often are left open due to rusted tracks or damaged hinges. This allows water to saturate the drive bay floor and sill timbers which can quickly rot. Damage to the threshing floor frame can also cause failure in the stone wall that supports the barn's "bank" by allowing the earth pressure to push the wall over.
