I purchased this shed in 2010 and am completely happy with how well it has withstood all the unusual weather that Colorado has to offer.  This last big hailstorm left a baseball sized hole in the skylight.  Imagine my surprise when I e-mailed Lifetime inquiring how I go about purchasing a replacement skylight and receiving a response stating that a new skylight was on its way to me.  NO CHARGE!!   This company definitely stands behind their products, no questions asked.  I expect this shed will last a lifetime!
