Vibrations with large tank

[Bthomas]

I'm having a new roof put on my house and the guy said there would be lots of vibrations to the point where they advise removing pictures from the walls ect..

I have a 150 gallon tank against an exterior wall. He said it will take some vibration but not enough to knock it over. The rocks in it are stable but not glued together. It's also over a crawl space so I have the floor to worry about as well.
Am I just being paranoid or do I have anything to worry about?

They won't create enough vibration to move or rock the tank unless they're setting off dynamite. Maybe slight vibrations from walking on the roof and hammering, but nothing I would concern myself with. I had a complete tear off and rebuild of my roof 2 years ago and my tank was on an exterior wall and there were 0 issues

I wouldn't give it a thought. The vibrations will be from the shingle removal and nail guns. We had our house done last year after a tornado customized it for us. The tank didn't even blink.

LR are buffered by the support of water surrounding them. It would take an earthquake to knock over LR sitting on one another inside a tank.

You can test this by grabbing a large LR submerged and it can easily be lifted until you lift it above the waterline......Then the LR become extremely heavy to lift out.... that's bc in the water all the water is supporting the LR

I had a roof put on in March. I was home the whole time. I think your Roofer is exaggerating prob bc it may happen and he doesn't want to be sued if a $10,000 piece of Art hits the floor.

Ok thanks guys

Let me ask another question along these same lines..
The tank (150 gallons) is sitting over a crawl space and I did not do any sort of bracing of the floor but I do know that it is sitting perpendicular to the floor beams and it's on an exterior corner of the house.
My spouse is on the heavy side and any time he walks through there u can feel the floor vibrate. I'm always worried about him walking in front of the tank. Should I worry about that?

I too had a re-roof 2 years ago and lots of noise and Zero Vibration in the house. What are they using to remove shingles- A Jackhammer??

When in doubt about the floor, you can easily install a floor jack or two in your crawlspace. If you make a 2x6/3/4" plywood/2x6 sandwich as a header between the jacks and the floor joists it will be the most solid part of the house.

Yeah I just know that's not something I can do myself so I don't wanna hire a contractor to come out if I'm not pretty sure that it's necessary.. :/

I absolutely recommend adding supports in the crawl (I did 2 2x4’s screwed together) My floor had a “bounce” to it also. I was very concerned about the tank, but it also now allows me to basically jump up and down and records won’t skip on my turntable

I suspect your floor will be find but supporting is cheap and easy and would be a nice extra piece of insurance. A while back on my local coral/ SW forum someone was having a 300 gallon-ish tank installed and decided to put jacks in his craw space but he left a couple playing cards space to see how much the floor would sink, after it was all filled up he could still get the cards between the gap but he snugged up the supports just to play it safe over the long haul. I have a 75 gallon DT and really want to go to a 125 once my wife agrees/ is out of town for a few days and I plan on adding some jacks or wood post under the tank just to be safe.
