man its hot !!

If you what is commonly called a rubber roof, Dicor sells what you need. If its a metal or fiberglas roof, all you need is a seam sealer like eternabond tape.

Its for heat. Not really sealing out water. Its just so hot inside sitting in the sun. I dont know if koolseal would help but im willing to try anything that will help. I even thought about rigging some kind of tarp over it to reflect the sun some. Any ideas ??

Yes. Do not use Koolseal on your roof. (Koolseal is a brand name of a roofing compound commonly found on older trailers. Absolutely do not use it on a rubber roof or on anytype of RV, or you will be paying $$$$$$$$ to fix the damage.
A tarp or something like a shed should help. If you are on the road, I suggest using your A/C(s) to cool down.

I have seen Koolseal or similar brands applied on rubber RV roofs and no issues, have not done mine yet but my neighbor has it on his and no issues after 4 years, can you let us know what the issues are since its all just rubber.

Ok thanks for the info. On koolseal. Its in a lot, in the sun and the ac running wide open and its still HOT. Ac is working good its just the sun beating down on it. The poor ac cant keep up, bless its little heart. I feel sorry for it. :) . might rig up a silver tarp over it kinda like pup tent style. Leaving the ends open for vintalation. Your thoughts ? other ideas ?

OPer Koolseal might help but not that much, during the hot months you might want to try the aluminum heat shield rolls from Lowes/Home Depot on some of the windows to help with the heat, most RV's just are not good above 95 degrees, here in Vegas we see 110 as our normal and with 2 ac's running full time its still not so great till sunset, so blocking the windows is the only way to keep it comfortable.

I want to say the roof on this 1993 allgro bay class c is fiberglass but i just dont know. Ill look into it. Some say " ive used it with no problem"and some "say dont ever use it" im new to this i dont have any idea. all i know is ITS HOT.

So many folks just don't know, I have seen the liquid rubber coating used on almost anything without any issues, here in the southwest its been applied everywhere and still no issues, I applied last year on my 20 year old roof on my home and its been great, have seen temps lower in house and now my 20 year old shingles will last another 20 years.

I should have applied this 10 years ago.

Might be best to call Tiffin inc. And ask them about this. Watching for other comments and thank you all.

Its a 93, just apply it you will be happy, but like I said above you need to block the windows during the hot summer months.
