Leaking Roof & no strata funds to fix

I'm a tenant in a two bed flat with a leaking roof. The water comes in through the downlights so something of a safety hazard. I've been trying to get it fixed since the beginning of the year without success and have now heard that there is no money in the sinking fund to get it sorted.

Should I just cut my losses and get the CTTT to cancel my lease or can the strata be forced into the repairs?

thanks
