What causes brown spots on kitchen ceiling?

Brown spots on a kitchen ceiling are typically caused by water damage, often from leaks in Plumbing, roofs, or appliances like dishwashers or refrigerators. Over time, moisture can seep into the ceiling materials, leading to discoloration and potential mold growth. Additionally, cooking-related steam and grease can also contribute to staining. It's important to address the source of the moisture to prevent further damage.
