In this case, I expect it's going to be blowing those ratchet straps after they become unanchored, turning them into whips that'll cleave the roof in half.

Look man I'm not a sciencologist but if a big ol tree smacks into that strap maybe the strap doesn't break but the metal tie downs? Idk man doesn't seem like it would work out well for the house or straps

A 2" wide straps is supposed to fail at about 10,000 pounds/4500kg of static load. The nylon strap will fail long before the metal hardware does, and the roof is going to fail before either of those do. If a large enough object fell on the strap, the most probable scenario is that the strap would end up acting like a wire cutter to the roof.

12

It might break the roof. Those straps are nearly as wide as that truck's brake lights, i don't see them snapping so easily.

if one of them goes, the other is pretty likely to go as well. Unless you just didn't secure it properly, in which case skill issue.

Hurricanes rip poorly built roofs off all the time. Builders get lazy and install the hurricane anchor things wrong. At least the local home inspector on Reddit used to say

That particular redditor had a long history of weekly posts with the shitty home builder work they inspected, but I hear the argument, I have no evidence other than hearsay and didn't research it myself.

I wonder what the vibration frequency of those straps is, once the wind is blowing through them.

Will they vibrate the roof into mush before they pull out of the ground and become metal ended whips?

As someone who straps, I felt this in my soul. God I hate that noise(I use tarp clamps for dampeners).

Gotta be careful though, twist in the strap can ruin the strength limit of the strap if it's under load

Edit: others have pointed out it's for cargo straps specifically. I guess I was thinking of more knotting than twists. Either way, just follow the instructions.

It's congratulating Don Quixote for trying to preserve chivalric code, no matter how misguided it may be, with the result being better than what you'd think at first glance.

17

Cervantes actually didn't like the concept of chivalry and was considering a "companion" novel where he depicts chivalry as it really was. It's pretty unfortunate that he never wrote it because I'm sure it would have been a classic.

Jesus Diaz was afraid the roof would blow off. And while the straps are gone, the roof stayed put. His home didn’t sustain damage, either.

Meanwhile the row of houses a street over that got raked with his modern-day chain shot are ravaged

Unless there's a footing these straps are being anchored to that I'm not seeing, I doubt it'll do very much besides potentially acting as very dangerous whips.

You'd be surprized how strong an industrial screwed-in ground anchor holds. And it has to be anchored at the correct angle towards the load.

So, most likely, they will not just rip out, and they have a good chance to add a significant force holding down that roof.

If done properly, of course.

11

If the roof doesn't crack from the added pressure points.

There seems to be an extra bar/pole at the top to distribute the load, though.

2

I’ve seen these deck strap things that you push way down into the ground and as you pull them up a little the flatten out and turn sideways. Really easy to install and harder than hell to pull out. I think it’s called an earth anchor maybe. I bet that’s what he used here.

4

yeah these look like footings to me, i see what looks to be a small concrete protuberance right out of the ground. Also these would likely just pull out of the ground if they weren't anchored, and they wouldn't be whips, just very odd debris.

1

Yeah I watched a short news clip with him in it and he said they are attached to concrete that goes 8 feet down.

YouTube recommended a video of this to me yesterday. The straps are anchored with cement. Seems like it buys him X additional mph of wind speed compared to his neighbors. We'll see if the winds are in that "more than a regular roof can handle but less than the straps can hold" range.

Yyy, I've heard all the theoretical arguments. I now want to witness the experiment live. Or on camera.

I’ve heard all the theoretical arguments. I now want to witness the experiment live. Or on camera.

you can do a pretty simple small scale test, with something like popsicle stick houses, and instead of wind loading, static loading against the wall. It won't scale perfectly, but it should demonstrate the concept.

1

Seems like a plausible strategy. If the roof is lashed down it can't catch the wind and therefore is less likely to weaken over time and go flying. Certainly better than doing nothing.

Lol it's a terrible idea. The wind would get a hold of those and they would essentially grind the roof away.

Better a damaged roof still attached to the house than a roof strewn a mile and a half downwind.

14

If it's anchored into concert blocks, it's not much different than internal hurricane straps that hold a roof on. They won't move, or damage the roof, you don't know that your talking about.

Wrenchreply
lemmy.world

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.

2
BassTurdreply
lemmy.world

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.

11
Wrenchreply
lemmy.world

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.

2

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.

5

ok so. This isn't going to stop a tree, or a large rock from flying through the side of you wall, but if you home isn't mounted to the foundation (common in old homes) or very well mounted, or just not very wind load capable, this could actually be beneficial.

You could still experience "wall buckling" but since the roof is relatively secured, you're acting from a separate point of leverage. Which is essentially going to be in the middle of the wall, rather than at the top of the wall.

This is all assuming that these anchor points are as strong or stronger than the straps and mounting hardware. And the fact that your home doesn't disintegrate between the staps.

It would prevent flat winds from removing the roof, for at least a little bit.

Zozanoreply
lemy.lol

Anywhere there's wind strong enough to lift the ceiling off, is going to be debris flying around and smashing the roof into pieces.

Any pieces of the house which would stay grounded thanks to the straps would need to be replaced anyway.

The straps are probably tight enough that the roof needs to be refurbished after, even if the hurricane didn't cause any damage.

That's not even considering the likelihood of severe flooding.

House is fukked fam.

BassTurdreply
lemmy.world

I'd rather replace a damaged roof instead of the whole structure and the resulting internal damage. Those straps are extremely strong. They can take a beating, but no doubt there's debris that can destroy them. If something is big enough to do that, then the wind is the least of the roofs concerns, because the rest of the house is fucked. The possible pros definitely outweigh the cons of using them, even if the don't end up working out.

22

No one is considering that the owner may have reinforced the roof from the inside either. Wouldnt be hard to determine where the straps are crossing the peak and add reinforcement to ensure the straps dont deform the roof, further adding to the structural integrity.

I find it so weird how people will spin a narrative based on assumptions and just disregard all the other possibilities.

If they buried concrete blocks, I bet you they had the presence of mind to reinforce the roof.

4

On the surface, it looks as if they bored decent size holes in the ground and set the anchors in concrete. With a Bobcat, they could easily get 3 meter x 40cm holes; that's 904kg of concrete at each anchor point, and a lot of friction.

This isn't the stupidest idea I've ever seen; given that they can't move their house, and set unlikely to move all their possessions for just a few days, Heck, it's not a bad idea at all, and looks well-executed.

I guarantee it's not deep enough. Hurricanes of this magnitude topple and uproot trees with massive root structures extending several meters underground. These type of DIY solutions are almost always create more hazard than they solve.

Those trees are also giant sails which transfers that much more force from the wind

10

they make houses rated to hurricane winds, i don't think the trees really care one way or the other. Engineering is often better at withstanding hurricanes than trees.

Now I'm just curious about what shape those anchors have, due to morbid curiosity.

5

By "does work" you mean you don't need to care about the anchors flying around and falling over you; you only have to care about the lines cutting you in half or that wood house breaking down when pressed against them?

If so, yeah, round and deep concrete tubes work.

Maybe they're getting ready to move the earth to another place in space and didn't want their house shifting around.

mobile homes are built like complete shit (mostly due to weight) so even if you strapped them they would probably still vanish at the sight of 80mph winds lol.
