Clicking inside walls after use of water

We recently moved (45 days) into our home in Florida with 12' ceilings and the hot water heater in the attic. Whenever we use the water, we hear a clicking noise in the ceiling/wall but only in the area above the master bathroom and office. At first we thought it may be a drip, but the clicking changes in tempo and can get very fast, it has also been happening the whole time we have been here and there are no water spots. Any thoughts??

That is simply hot water flowing through plastic piping, causing expansion and contraction "clicking" noises. No harm, no leaking, just clicking.
My ABS black plastic drainpipes have been doing the same thing for more than 30 years, and we've never had a problem.

if it is concentrated in the same area of the ceiling or wall it could be as simple as a support bracket for the pipe and as you open the water to use the pressure change makes the pipe bounce a little you that clicking if it is constant on the hot but not on the cold side its probably that
