Least destructive method for hardened

sealant on the roof. Its rock hard.
I wondered about a cold chisel, then an air hammer but I am concerned about damaging the roof.
Is there something that could be painted on to soften it up perhaps?
I have some new vents/gaskets coming from InlandRV but not all of them, so I am hoping to get this stuff off so I can remove the vents without destroying them. I am pretty good at demolition, not so good at careful and gentle

Thanks for any help or advice

Try a heat gun to soften it up, then use a plastic scraper or putty knife to remove it.

Solvent should get all of the residue off and give you a clean surface to work from for the new installation.

Thanks!
I've had a heat gun for almost ten years, this will be the first time it's been used.

It looks like the roof has been painted, right?

The large square (air) vent on the left looks original, but I don't think that the one in the right hand photo is (the smaller one in the second picture), or at least, it doesn't look much like the three plumbing vents on my roof.

But I guess you ordered a "real" one from Inland?

By now you probably know this, but I'll point it out anyways: there are three parts to that assembly: the chromed vent, the rubber gasket between the vent and the roof, and the piece of screen that covers the pipe (and goes under the rubber gasket) to keep out the critters.

Have a great Vulkem Day putting them back together!

I used a couple of 5 in1 tools to get the sealer thin, then used brake parts cleaner from the local auto parts store to soften the remainder for removal.

Sometimes a backhoe comes in handy, a local rental place can hook you up. JUST KIDDING !!!

A heat gun is your best friend unless someone used an epoxy from frustration trying to fix a leak, be carefull of cooking the paint.

Your vents are identical to mine for the holding tank system, Argosies had a funnel vent not a cap type like on the airstream models.

There is a nice inexpensive 5 in 1 scraper available at hardware stores that is stiffer than a putty blade. I have used mine for lots of things like scraping loose the floor tiles from the subfloor.

Just picture your self trying to get something off your hand with the heat gun and scraper and the aluminum will like you.

Good Luck

Hey Guys thanks for the awesome (and not so awesome) suggestions.
I am so eager to get to this but I am waiting for my replacement vents and seals from InlandRV and dont want to trailer to leak. We have so much rain happening right now, but at least my floor is dry after replacing the rear and applying Vulkem to the rub strip, rear end bumper/skin joint and rivets.
I think its time to tackle the plumbing.
Cheers

Bex

By the way, yes its painted, I believe its original as its an Argosy. I have (or will have) posted a question about that in another thread.
