I have 2 LifeTime sheds 1 is about 10 years old and the other is 5 or so years. I noticed on the older one the skylights where deteriorating. So thinking how I could cover them and not sure what to do. I went on the LifeTime web site and told the chat pop up portal. They asked what sheds I had and before I knew it they said you have new sky lights being shipped, no charge! Alright! Problem solved. Thanks LifeTime for standing behind your product. Glenn O ><>*
