Water spots on ceiling

Hi everyone , I recently bought a home back in September! All of the inspections came back good including the roof, however we are going to need new shingles in 3-5 years. Recently I have been noticing a couple water spots showing up in different areas around my home. More specifically around my ceiling can lights. Does anyone know if this is a roofing issue or possible a moisture issue in the attic? Who should I call to come inspect the problem?? Thank you!
