Thanks everyone for your feedback and advice. No, the RV Service Center in question is not nearby, and I will never go back to them.
I have already purchased a tube of Dicor self-leveling sealant, and will go ahead with the repairs.
Given the open holes in the sealant in the photos, what is the best method to prep and clean the damaged sealant before applying the new sealant?
And yes, from now on, I will be going topside at least once a year to inspect the roof and perform pro-active repairs.
You may find this, of some benefit.
First, I am not sure why you have open holes. almost looks like the dealer dug into them.
Second, from my experience the dealer will usually tell the customer, all the dicor, needs to be removed and replaced. That is what they told me. I believe that to be untrue. All the below is from my conversation with Dicor tech services
Third, Dicor sticks to Dicor, clean with denatured alcohol and dicor over, all Holes and cracks
Forth, and this is a big point in my opinion, my dealer, said all Dicor needs to be replaced every 2 or 3 years, at that $1300 type cost. Not true after speaking to Dicor
Fifth, Dicor tech said no. They said when the Dicor is bad, and needs to be replaced, the following occurs.
A) it is not longer pliable ( thumb nail test, meaning if it is hard brittle, and your thumb nail does not leave an imprint), then it needs to be R@R
B) the Dicor is peeling off the edges of the roof membrane and lifting up.
If it not doing the above, clean, as I said above, fill all cracks and holes, inspect 2X a year.
Our RV is now 19 years old. I have followed the above protocol and to date, zero leaks.
Hope, this helped
