20lbs is nothing for a strong gust of wind on a roof.

Flat roof, low profile, is very different from even an 1/8th inch gap on a slanted roof.

  You really need to stop replying to every reasonable comment pointing out a very real risk with all this ignorant nonsense. You know not a thing about air flow on that roof (or anyone else's), and you seem to be utterly clueless as to how powerful even mild gusts of wind can be. Trying to convince people they DONT need to take reasonable safety steps, even when presented with knowledgeable arguments that are clearly better informed than yours, is incredibly irresponsible. Please reconsider.

    Run some actual math > fear. Yes, in a slightly different situation this would be an issue. But, wind is not magic fairy dust that can lift arbitrary loads.

      Look, there is a reason why people secure stuff on rooftops. What are you arguing here: That it's okay to leave shit around because the chances are low that it will kill somebody? Just stop with the flawed logic.

        No, I have no problem saying securing stuff is generally a good idea. If nothing else it makes it harder for someone to steal it. My point is the specific bad thing described is unlikely to happen. And sure I got a lot of knee jerk reactions but nobody actually did any kind of meaningful calculation demonstrating an issue.

        It's not a knee jerk reaction. You have limited view of the problem. I've lived next to a three building being constructed as a kid. The amount of stuff flying is unreal. You aren't accounting for cats, earthquakes, determined birds, malicious intent, gravel under the panel+wind, strong rain that may move the board and angle it. Your sole argument is, historical wind speeds won't lift it. That is not realistic, naive and outright dangerous thing for which people actually get badly hurt or die. But, I don't see you slowing down in this thread, so I doubt safety concerns will reach you.

        Thank you for trying to reach this person. I think they perceive the safety recommendation as a direct attack on logic and mathematics.

        Ehh, I just said I had no problem tying something down. Especially in earthquake country. Just that wind was unlikely to lift a panel, but rather than admit they where wrong everyone keeps doubling down as if wind where the only issue.

        >It's not a knee jerk reaction. Followed by a knee jerk reaction without any facts backing it up... > That is not realistic, naive and outright dangerous thing for which people actually get badly hurt or die. PS: Potted plants are often placed on the top of flat roofs with a lip and don't get tossed off it by the wind. The reason has to do with how the wind is deflected over the building and the obstructions around it. Often pushing them in opposite directions from the wind because of a giant counter rotating vortex of air. But, be happy with your inaccurate and over simplified model of how the world works.
