Morphology
The phrase combines 'shoot' (move or rush quickly) with 'through the roof' (passing the highest point/limit), so the meaning of a very sudden, dramatic increase is a metaphorical extension of the literal parts and is partly inferable. However, the specific sense of rapid and large increase is idiomatic/metaphorical rather than purely compositional, so a B1 learner might guess the upward/rapid sense but not fully predict the conventional usage without prior exposure.
Etymology
Shot through the roof comes from the image of something being shot straight up and breaking through a roof, so it jumps very suddenly to a much higher place. That's why we use it to say numbers, prices, or feelings 'rose very quickly' or became 'very high'.
