Ceiling vapor barrier

[MustHang]

Hi,

I'm currently finishing my insulation with the roof and I was wondering what I could do with the vapor barrier since my garage doors are already installed.

I mean the rails are already bolted to the trusses with lag bolts. Should I remove them(just doesn't seem good to remove lag bolts from wood and then put them back). I fear that the wood will be weakened. Or do I just go around it ?

Thanks

I would remove the bolts to install the poly moisture barrier and then reinstall them. Snug them up and all is well, no weaker-no stronger.

If your worried about the lag pulling out just before you reinstall the lags fill the holes with PL400
after that you will never get those lag back out.

Put the lags back in the same holes and what would be weakened?

^^^^^^Something about the wood fibers weakening when you pull a lag out and put back in.
We install x-rays on walls and it is not an acceptable practice to reuse holes for lags.
But that for 800 lb x-rays that need to withstand 1500 lb put out force.
For just a garage door I wouldn't worry about it.
Your not pulling engines with your garage door are you?
