The surface area on those straps isn’t really going to grab the wind particularly bad. If the metal connection to the anchors actually holds up, it might actually do a little good.
But if there’s enough lift to pull that roof up without the straps, it’s almost certainly enough to snap the anchor connection, assuming the anchors themselves are deep enough to stay put.
More likely though is that these just snap and become hurricane whips with barbed ends.
Edit - or catch debris that snaps them before the wind even has a chance to rip the roof off.
The tonnage rating on those straps is insane. With relatively even force between them, they provide way more holding power than the roofs fasteners do. They would also help prevent that initial peel back that just creates a sail inevitably taking the whole roof.
Yeah, under ideal conditions. But shrapnel creating cuts, lateral forces from debris, cars rolling over them, etc. I see them loosening quickly at best.
But yeah, besides the whole risk of making barbed hurricane whips, it doesn’t seem quite as stupid as it looks. If they’re really lucky and only fight the wind itself, perpendicular to the roof, they might actually help.
Some friends of ours strapped down their roof for Hurricane Georges. They lived in a wood frame house on a hill and knew better than to just trust that everything would be ok.
Anyway, they still had a roof after the hurricane, but the winds were still strong enough to lift the roof up, damaging the joints between the rafters and the main posts holding the roof up. This damage I saw with my own eyes.
Wind shear can be remarkably strong at 140 mph, blowing across a roof like that. It would be a shame to lose the house because you didn’t take two hours to put some straps over it.
