Is Bathroom Ceiling Mold Dangerous?

 
Mold growth on a bathroom ceiling looks gross and is very unhealthy, and mold stains can be challenging to clean. It can also lead to permanent damage to your home. Thus, moldy ceilings must always be checked by a pro and treated as soon as possible.

Typically, ceiling mold growth has a black shade. If you look more closely, you may identify visible spores and filaments in the fungal structure. In such a case, there is a hidden and possibly, a serious problem.

Most often, you can spot mold growing in ceiling corners and particularly above the shower where it gives an unappealing sight. Mold grows rapidly on ceilings because people don’t clean the affected places properly. They usually clean the floor and wall tiles but forget the ceiling and that’s where the mold growth occurs the most.

Before we explain whether bathroom ceiling mold is dangerous, let’s discuss what exactly causes mold and what kind of mold grows on the ceiling.
 

What Causes Mold On Your Bathroom Ceiling?

 
Before removing mold from a surface, you need to determine why it grew there in the first place.
The most common causes of mold on a bathroom ceiling are:
 
Poor Ventilation
 
Is your bathroom not ventilated properly? Poor ventilation is the most frequent cause of the widespread mold growth on the ceiling and walls. Currently, the building codes require that every bathroom needs to have a fully functioning exhaust fan that vents to the outside of the building.
If you keep the door closed and don’t open a window or use an exhaust fan, it will result in poor air circulation in the bathroom.
 
Hot Air and Moisture
 
The process of condensation is another reason for mold growth on your bathroom ceiling. Every time you take a shower or a bath, the bathroom becomes damp and fills up with water vapor. Hot air rises and turns into moisture as soon as it hits the cold ceiling.
This gives mold an ideal environment to grow as it prefers humidity and warm temperatures. Eventually, mold starts growing everywhere in the room, but most heavily on the ceiling where moisture and hot air stay the longest. Thus, it is recommended to run an exhaust fan while taking a shower and for one hour afterward.
 
Leaks
 
There also might be a leak in the bathroom that’s feeding the fungus. Before removing the fungus, find out where the excess moisture is coming from and fix the issue. You can be sure that the mold will come back if you fail to fix the root of the problem in the first place.
For example, if you notice that your ceiling is wet and moldy but the walls don’t show any water damage, you might have a leaky roof. So, you need to repair or replace the damaged roof first.
 

 
 

What Kind Of Mold Grows On Bathroom Ceiling?

 
Mold types that typically grow in bathrooms include Cladosporium, Aspergillus, Penicillium, and Stachybotrys. The different types of mold look very similar, mostly dark brown or green, so it is quite difficult to tell the difference.
However, among those varieties of mold, Stachybotrys, also known as black mold, is the most dangerous type that often appears in bathrooms. It looks very dark, almost black. Penicillium mold colors range from green, blue to yellow.
Cladosporium fungus appears in olive green to brown and black, while Aspergillus is usually black on the surface and whiteish or yellowish underneath.
 

Is Bathroom Ceiling Mold Dangerous?

 
Even though black mold on your bathroom ceiling will not kill you, it is definitely not safe for human health and the structure of a house.

If you’ve noticed black mold (Stachybotrys) in your bathroom, it can be dangerous and thus, requires immediate removal by a specialist. This type of mold is typically found in the most humid areas like the shower, bathtub, toilet, and ceiling tiles in a bathroom.

If you come into direct contact with this kind of mold, you may experience black mold poisoning and any symptoms that come with it. Mold spores can produce mycotoxins that cause severe health issues and therefore, could be dangerous to humans. Some medical studies show that these toxigenic molds can lead to serious illnesses like pulmonary hemorrhage or memory loss, however, this is rare.
 

Can Mold On Bathroom Ceiling Make You Sick?

 
As some types of mold release toxins, hidden molds can have a bad effect even on a healthy person. Black mold leads to various health problems like allergies and respiratory infections.

If you are exposed to black mold for an extended period of time, you will most likely develop symptoms such as coughing, sneezing, stuffy nose, nausea, lung irritation, headaches, fatigue, itchy eyes, and skin irritation. And if you are already suffering from asthma or other respiratory conditions, the black mold could make your condition worse and trigger serious reactions. Any of these symptoms could be a sign that you have been exposed to toxic black mold.
 

If you notice mold in your bathroom ceiling, it’s a good idea to contact a home inspector to test your house for mold and also seek advice in case you notice any signs of water damage or moisture problems.
