Here https://math.stackexchange.com/posts/2464089/revisions is a question were [roots] was added and later changed to [radicals] (after a now deleted discussion between me and Michael R). I still don't see the value of adding [radicals] to all questions where a square root is used somewhere in an answer ...
I will just point out that roots is for roots of polynomials and radicals is for square roots, cube roots, etc. (But you probably know this and the question was mainly whether the tag for square roots - which is (radicals) - is suitable there.)
An edit has been made after reading some answers:
I recently encountered a seemingly simple trigonometry question which I cannot solve properly.
Consider the equation $\sin{(x+\frac{\pi}{4})}=-\frac{1}{3\sqrt{2}}$.
Note that since $\sin{(x+\frac{\pi}{4})}=-\frac{1}{3\sqrt{2}}$ it follows that...
