I think that in order to explain my thoughts on this I want to explain how warehouses transport pallets of stuff with plastic wrap. Using plastic wrap for transporting/moving stuff is incredibly useful, but not how you might think. It's not that the stuff inside is any safer than if you didn't use it. It's more that the stuff inside is incredibly contained and likely to hold it's shape even if things start to break. Which means you won't have a giant mess to clean up, and you can reasonably rely on it to support any other things stacked on top of your pallet.

This wouldn't work for safeguarding your house, because if you've ever dunked something wrapped in Saran wrap you'll notice that it's not always water tight. Add extreme winds and the wrap will likely peel off and make things worse. I think you'd probably have a giant mess, and be no more protected than if you didn't use any Saran wrap at all
