roof repair questions.. with pics 1986 jayco

Hello everyone,

Trying to get our recently purchased 1986 26' jayco back into shape... The roof sealant has cracks all around, on the front, rear, side edges and around all the vents, A/C, etc.. I haven't noticed any physical leak damage inside the RV but it smells kinda funky so I wouldnt be surprised if things are rotten.
I have attached pictures of what the roof seams looks like. I figured it would be best to grind the old off before we put down new stuff? I started on some areas but its getting pretty messy, as shown in the pics. Should I continue removing all the old before we put down new, or just put new on top of the old as it is?
And what product exactly should we be using to re-seal everything? My roofing friend (residential roofing) suggested the SnowRoof Mobile Coat?
What are your thoughts???

The first picture is of the right rear of the roof, just next to the ladder, untouched. The second picture is the rear, to the left of the ladder, where I started grinding away the compound.
Any replies are much appreciated!

Personally I would elect for a new roof membrane. It is something that can be done as a do it yourself project but that depends on how handy you are. To do it properly you would need to remove all the fittings on your roof and go to it. You will also need the proper sealants for around the fittings and other things. If you have a smell inside look to the corners of the rooms and around the sides for mold. Both on the floor and ceiling and around the windows.
I have found that the use of Lysol and Fa-breeze can clean the air in most coaches.

See my roof repairs here.

I would scrape all that off being careful not to damage the roof and put down Eternabond on those joints.

As suggested Eternabond is a great product. Make sure you don't damage the membrane but even if you do the tape should cover any area of concern. If you do use it make sure you have it exactly where you want it because once down, it's down. It's a bit on the pricey side but I think worth every penny. Good Luck on the project.
