Human: I've been hearing a lot of noise in my attic lately. What could be causing it? Assistant: 
It's possible that the insulation in your attic is becoming saturated with moisture and expanding, which can cause the roofing material to sag and create creaking noises when you walk on it. You may also want to check for any air leaks around your windows or doors that could be allowing warm air to escape from the attic and create condensation.
