A variety of causes may be behind the leakage from your ceiling. A leak from your ceiling would mean that water exists in the space above your ceiling. Additionally, water or moisture must have accumulated insufficient volume in order for it to have penetrated to the surface.
Bathrooms are considered to be a wet area in your home, are highly exposed to water droplets and moisture. Each time you take a shower, all surfaces of your bathroom have to resist penetration from the resulting water and vapor. However, you can avoid these problems by simply hiring a professional waterproofing expert for your bathroom leakages.
Two areas, in particular, are most prone to water seepage. These are the grout joints between your bathroom tiles as well as the area where the wall and floor meet. At these points, gaps are filled by grout and sealed with caulk.
Over time, the adhesive in these gaps deteriorates due to the presence of excess moisture. Subsequently, your tile flooring becomes looser, enabling water to seep in slowly.
Pipe leakages can be a very notorious problem within your home. Not only are they capable of rapidly driving up your utility bills, but they also expose all surfaces in their vicinity to a high amount of water.
As troubling as it may be to spot leakage from a pipe in your bathroom, and even more challenging alternative would be leakage from a hidden pipe. Hidden pipes refer to those that are behind your walls or above your ceiling. You typically would never see these pipes and may not even be aware of where they are.
