Caulk/sealer

I have a 2004 Monaco I need to caulk around the satellite dish base. The satellite itself is mounted to a platform approximately 4 x 4 and I need to seal around that base where it meets the roof. Any recommendations on the best caulk/sealer to use? Thanks

Dennis, thank you! I’ll order it. Just curious because this is my first time doing it, what’s the specific purpose for “self leveling” sealer? Thanks again

Exactly, and it does not harden. The key is to apply to a clean surface. I have used denatured alcohol.

You might want to put some butyl tape under the perimeter of box and make sure under the screws/ part of that perimeter. Unless it's already mounted .Start your bead over what you want it will flow down to roof . Do a little practice bead mock up on cardboard box before getting up there . The caulk gun with release button is nice ,it will want to flow for a bit even after you hit release. worse without. Have paper towels ready and some alcohol ready for drips and oops You put it over exposed screws too.
There are a ton of vids on utube mounting vents ect. using it
Examine other parts might need a touch up.

Tape it with 4" or 6" Eternabond once and worry about it no more.

I am going back and forth on Eternabond. Mostly because i am getting ready to remove about 50' of aluminum faced black mastic tape. I peeled a 8" section back today and holy moly what a PITA. Not sure what the life expectancy of eternabond is but when I get done with 50' I may want to torch the entire rig if it every needs an entire reseal.

Thoughts and comments welcomed.

Eternabond says to use a heat gun to soften the glue base and gently pull up the tape.
Eternabond also makes a roof sealant caulk that is far superior to the flow out kind ( Dicor )and it doesn’t attract dirt

When sealing a step edge the last sealant you want to use is self leveling. If will flow away from the edge you are trying to seal leaving little if any of the product where you want it. Works great if you are filling a void but does little other than to make a puddle of sealant when used to seal a vertical to horizontal meeting point as described.

Either tape it or use a non-self leveling sealant.

thanks, I didn't think about the heat gun even though i use one for virtually every sticky application, da. Have purchased self level and non leveling.
Any thoughts on sealing the horizontal roof seams with a small bead of self leveling with 4" Eternabond on top of it after setting up.

2000 Monaco with aluminum roof with typically to much junk on the roof. It even has a penetration for a CB radio and old satellite dish base and receiver brackets, they don't leak so the old adage of it ain't broke is being contemplated!

The Eternabond tape comes in 1”,2”,4”and6”. Also in white, black and aluminum. I did my entire roof with the white 4” tape. Covered all seams on the roof and then sealed the sides of the tape with a small bead of Eternabond sealant(caulk). The secret to a permanent roof sealing is a scrupulous roof cleaning where the tape is being applied And sealing the sides of the tape. Did mine two years ago and it looks like I just did it and my coach sits out in the weather.

Ok, tackled a 4' section where the front cap meets the aluminum roof. What a nasty PITA. So I used Goo Gone professional, good stuff works like a champ. But the black mastic is like all black mastic's it is literally everywhere and it is a mess. lesson learned. I'm going to take 12' painters paper and cover the adjacent areas for about 20' in every direction, just kidding. Took about 2 hours to remove tape, mastic, clean up and caulk. Going forward with the eternabond and caulk edges. Looking to eat this elephant one bit at a time, should be done by 2034.
