From the moment you spot that unpleasant, brownish water stain on ceiling, your mind starts plotting the fastest ways of getting rid of it. Addressing the water stain could help solve the problem momentarily, but the ugly stains will be back until you fix the problem at the source.

Water stain on ceiling result from several causes, most of which are moisture related. The fastest way to do away with ugly discolorations on your ceiling is, regulate the humidity levels in your house. Plumbing problems could also be part of the problem. Some of the common causes of roof stains are:

Condensation from bathroom vapor

As you enjoy that hot bath, the steam escaping moves to the coldest parts of the bathroom condenses and forms ugly stains in the bathroom. If the bathroom exhaust fan that reduces moisture connects to un-insulated ducts, some of the moisture escapes and condenses in the attic which then results in brownish stains on your ceiling.

Poor attic insulation

The insulation in the attic is critical. If it does not hold properly, your house will suffer hideous water stain on ceiling as the moisture condensing in the attic becomes the dreaded discoloration. Moisture from the attic comes from a roof leak or bathroom moisture.

Mold Damage

Mold is dreaded more than water stain on ceiling. It is even worse because it causes the stains. When the humidity levels in your house are very high, they provide the perfect conditions for mold formation. When water condenses on the ceiling making it damp, mold grows in the area. The orange mold is usually first to appear as a brownish patch, but after some time, it gets darker if not addressed. When you treat these mold sometimes, it leaves ugly stains on the ceiling.

Roof leak from damage or ice dam accumulation

The stains that occur at the corners of the ceiling are mainly as a result of ice dam leakage. The more pressure the roof suffers from the ice dam, the higher the likelihood of a leak. If there are broken shingles, the possibility of a leak is high which then results in ceiling stains.

Water condensing on any part of the walls or ceiling eventually dries up. However, the discoloration does not go away unless you take steps to address it.
