WOW...We bought a shed 9 years ago and the panel on the roof started to warp on us within the first couple years but we didn't do anything about it until we had the shed for 9 years, by this time the shed was not waterproof anymore.  We filled in the warranty form explaining our case. Dany responded the next day and in a weeks time we had the parts we needed to repair the shed on our doorstep. 
Thank you so much for the great service....
