I am pretty sure that it is not supposed to do that!
The edges are disintegrating, so UV made it brittle, despite my treatment.
The walls don't seem brittle, though, but the wind couldn't grab it like the roof, especially since the wall siding overlaps each other, but only the top roof panel overlaps the others, but then it was easier for the wind to catch it.
These are the correct panels, $90 each, but currently unavailable from Home Depot.
These are the $22 connectors, although we found ones for a fraction of the price.
These are the correct panels, $86 each, but currently unavailable from Lowe's.
Lowe's showed 2 in-stock, which wasn't enough, and I couldn't find anything like it in town, so I figured that I would need to screw a 2x4 to the front edge to hold down the old sheet until I could replace it.
I would just need to rent a truck twice to transport 1-2 sheets of plastic each time.
These are the $11 connectors at Lowe's.
I figured that I needed the connectors because this isn't flexible like coroplast.
I haven't had a chance to install them yet, I was busy with Mom's 75th birthday.
