Hello,
We are very sorry to hear about this! Please note that this shelter is not live load rated, and keeping snow off the roof area and anchoring the unit on all reps, is strongly recommended, and is listed on the manual. We do offer wind and snow-rated shelters in a size very similar to this one which may better suit your needs. Customer satisfaction is very important to us, and we would love to further discuss your options with you. Please give us a call at 1-800-932-9344.
Thank you
