What I have so far is:

-10 = v(initial) t - 4.9 t^2

-12 = v(initial) t - 4.9 t^2

How do I solve this question if I don't even have initial velocity?

You are quite right. You need additional information, for example maximum height attained, time it took to come back to the top of the roof, initial velocity, etc.

On the other hand, the height of the building (30m) is immaterial.
