I purchased my Morton building in 2006. Growing up around Morton buildings and after researching other types of buildings, I felt Morton was a superior building. I thought construction of the building went great. The first 12 years of ownership were without any problems. I then noticed my roof was leaking. I figured it would not be a big deal as I would just climb up on the roof and tighten the screws ( I assumed Morton would install the roof panels the same as the wall panels using screws). I was completely surprised to find they had installed the roof panels with ring shank nails!! There is no easy way to remove ring shank nails without damaging the roof panel! I was able to set a few of the nails a little deeper. That appears to have slowed the leak down. Now my door weather stripping is in need of replacement. I cannot get anyone from Morton to help me purchase new weather stripping. I have called all THREE offices in Missouri (over an 8 month time span) and no one will call me back!!! If I would have known this is how Morton treats their customers after the sale, I would have purchased a building from a different company. Needless to say, I used to brag about my building to friends/family/neighbors who were considering putting up a building themselves. I definitely no longer recommend Morton!!!
