My question is.... As I have removed the roof vents, a/c and cleaned off all the old 'goo' (still have to do some cleaning up there).... Would it be better to paint the entire area BEFORE I reinstall Fantastic Vents and new a/c unit. Or would it be better to hold off on the roof coating until AFTER components are installed and sealed in the usual manner? Which manner would provide the best future leak prevention?
Thanks for your input!
I would re-coat AFTER
all of your roof-top appliances are in place. This is to allow the gaskets to adhere to bare aluminum and eliminate any possibility of a leak if your new roof coating does not adhere properly (for whatever reason) to the aluminum.
I do a lot of roof re-coatings, particularly on EPDM rubber roofs. Short of a total replacement of the EPDM membrane, we leave everything in place on the roof and coat around them.
Just a side note, I find that DICOR products are the best for this type of application.
