How to Identify the Causes of Ceiling Leakage?
Ceiling leaks occur when the building space above the ceiling is inundated with water or moisture, finally penetrating the ceiling. Leaks are observed as discoloration or dripping water through the ceiling.
Ceiling leaks indicate a faulty plumbing system or an improper rainwater drainage system of the rooms above.
This article discusses the possible ways to troubleshoot the cause of ceiling leaks and ways to deal with them.
Before rushing to repair the leaks on the ceiling, it is essential to identify the underlying cause. Mitigating the root cause of leakage results in effective repair of the ceiling structure.
Some common causes of ceiling leaks are toilet leaks, shower leaks, sink leaks, or roof leaks. All the mentioned leak sources are examined in the following ways:
1. Bubbled Paint on Ceiling and Walls
One common sign of ceiling leaks is bubbled ceiling paint. In few cases, these leaks, in the form of blisters, can pass through the ceilings and continue down the walls.
Paint Blisters and Dark Water Patches on Ceiling
2. Dark Water on Ceilings
The leaking water is usually dark-colored and is easily identifiable when the ceiling is light or white. It may smell musty. In certain cases, this water can be clear or odor-free.
3. Ceiling Patches after an Event
Sometimes, events like rain or snow or water leaks in the toilet or bathroom due to faulty fixtures can create patches. It may also show previous ceiling leaks.
How to Repair Ceiling Leaks?
The leaks can either be external or internal. In addition to plumbing line issues, faulty rain gutter systems can result in external as well as internal leaks.

Once the root causes behind ceiling leaks are identified and corrected, the next step is to repair the damaged ceiling. In most cases, the ceiling supporting structure (drywall) may be wet, rotted, or damaged. In such cases, drywall requires replacement.
In less severe cases, the ceiling may have leak patches that can be cleaned, plastered, or painted again to regain its look, But very acute leakage issues may demand the replacement of the ceiling along with the drywall. This also depends on the type of ceiling material used in the building.
