I'm not speaking from experience but in general the liklihood of a leak will be impacted by the climate in which you live. silicone is not a permanent solution if you live in climates where you have cold winters and hot summers. over time the silicone will lose its ability to be water tight. many use butyl tape like you have done and many just use silicone and have no issues
the best method is to use bonded sealed washers that are designed to create a weathertight seal. like I said above, many people will successfully install roof racks with silicone and have no issues. the best method is to inspect the seals every year or so and even reseal every few years
