Sheet metal over sheet metal?

[ITSANSS]

Hey, guys! Had a question for ya’ll.... I’ve got a barn with sheet metal siding...probably 40 years old or so...the metal is needing paint and is rusting in spots, has a hole here and there and has quite a few dents and dings. Question being, can I put new sheet metal directly to the existing sheet metal? Without putting some furring strips first? The way I figure it is this will make the siding material match my other buildings, take care of the paint issue, and most certainly take care of the dents and dings. But my concern is, will there be enough material for the fastener to attach to by just going into the sheet metal? Or will the first big wind strip off all the metal? Lol

Thanks!!

It depends...... how is the existing metal attached?

The issue with putting new sheet metal over the existing is that the existing fasteners will rub against the new sheet metal and probably wear a hole it in over time.... many holes...

The better way would be to strip the old sheet metal off and install the new... adding the appropriate trim details, weather proofing, etc as you do so.....

Are you sure the metal ribs are the exact same size ? Either way, I wouldn't.

I'd take the metal off and use it for a ceiling inside or to cover the walls.

Are you just patching a hole? Or putting entirely new panels over the existing panels? Patching holes is just fine. Putting new panels over the existing panels will have an issue with the existing screw heads that are sticking out.

Bad would be scraping and scrubbing and places that would trap moisture between the two. Obviously the new metal is pretty well protected but combine the above and you may have a problem a lot faster than you want.

You will have to remove all the screws anyway so just replace the sheets and sell the old stuff. A Craig's list ad will have it all gone by the end of the day.

If you were closer I would be more then happy to take them off your hands.
Looking for a rustic metal to do the bottom section of my garage.

As said, I also would think the screw heads will be the issue.

It is done all the time for roofs ( installing new metal over the old ) seems doing it on the walls would be easy. look up videos on youtube about how it is done for roofs, several different techniques are used.
