I learned a hard lesson about buying structures designed for Canadian winters!
The shed you see in the picture was purchased at Costco. Quite inexpensive for the size of the shed but it is totally unsuitable for the volume of snow we get in Canada. Manufactured in Israel - sold in Canada...
The problem is the snow load on the roof. We received and had over 4 feet of snow on the roof. It would have collapsed for sure if I have not strengthened it with a few pieces of plywood!
Actually the shed was well engineered - not just for Canadian snow!
