How to Know When Ceiling Cracks Are Structural or Just Old

Check the ceiling for areas of bowing or warping, particularly around the cracks. These areas are typically indicators of failing drywall adhesion and age, rather than a more significant structural issue.

Inspect the ceilings for areas of discoloration. Discoloration can indicate a ceiling leak or buildup of moisture. Moisture damage is a common cause for ceiling cracking, particularly in bathrooms. Moisture-related cracks generally do not indicate a serious structural issue.

Check for accumulated drywall dust and/or ground bits of paint in and around the crack. This dust can be an indicator of slow-forming cracks that are frequently associated with structural issues.

Inspect the walls adjacent to the ceiling for cracks that align with the cracks in the ceiling, running vertically from the ceiling toward the floor. This cracking pattern can be an indicator of serious structural flaws.

Note the location of the cracks in the ceiling. Cracks that run along the borders of the wall are more likely to be caused by the natural settling process. Cracks in the center of the ceiling are more likely caused by structural issues.
