Roof (Caulking/Eternabond)

Need some input,

I had several cracks in my bathroom skylight outside and did a repair with eternabond.
Jayco sent me a new skylight and said no recalls on this item. I believe this happened because the screws were to tight and cause the cracks. I know a great mobile RV service and had them do the repair. The skylight was a little different but the teck said it would work and it did. He did a great repair job and also used eternabond. The call out and repair totaled $268.25 but he cleaned every bit of calk off and resealed with new tape and screws. It is a nice looking replacement! I had just got a cast off my foot so climbing was not good at the time.
Now here is my concern. My trailer is a late 2010 Jayco and called a 2011. The teck who I trust said I should have the roof cleaned and the old calk removed and eternabond put down to make the roof last longer. I cleaned the roof today myself and it looks much better. I was wondering if the old caulk should be removed. It looks a little grey not as white but this should be normal for a 2011. I check the roof often and things do get dirty. Do you think I could put the eternabond over the caulk from the factory and over the front seem. No trouble yet and caulk has good bond just not white a grey tint to it now from road dirt. Also when washing the roof I sprayed with a soft spray around the freidge vent and noticed some water inside the outside freidge vent. No damage but does the top vent need covered when washing. What say you!

Eternabond has it's applications, but I trust the caulk more.
As long as your caulk is good and not developing cracks, I would leave it be.
After small cracks develop, I clean, re-coat with sealant and it's good for another year.
Once you see edges lifting up on the sealant, remove the sealant the best you can and start over with a new layer of caulk.
