You HAVE to get on your roof at least 2x per year and inspect it. I have Eternabond on all the seams and I still visually inspect it 2-3 times per year. If you think you see a crack in your caulking, fix it then- but before you do that be sure to wash the roof well. This will help reveal any cracks as well.
