Damp patches are caused when moisture is able to accumulate below the surface in materials throughout your home. The most common cause of this type of damp is condensation, although leaks in pipes or gaps in your roof can also cause moisture to soak into walls and ceilings.
Ceiling condensation isn't just unsightly; it's a sign your home is improperly insulated and ventilated. Without proper airflow, you could breathe in stale or hazardous air. Moist climates encourage mould and mildew, which is terrible for your health.
You might panic and think, “There must be a roof leak!” But that's not necessarily always the case. There's a good chance that the water you're seeing is just ceiling condensation. This doesn't mean your roof has a hole, but it needs to be addressed as soon as possible to prevent damage to the rest of your home.
One of the most common causes of ceiling leaks stems from plumbing. Water from inside your pipes can leak due to rusty or worn material. And, in adverse temperatures, pipes can 'sweat' or even burst, causing water to escape. Your leaky ceiling may even be down to a roof leak.
There are two main reasons you could experience water leaking from ceilings: Either there is an issue with your plumbing, such as a damaged pipe or leaking shower. Or there is an issue with your roof, such as a hole or overflowing gutters.
Leaking Pipes or Plumbing Issues
Leaking pipes or other plumbing issues can cause damp patches on the ceiling. These issues can arise from broken or damaged pipes, clogs, or other plumbing issues. The damp patch on the ceiling will typically appear directly below the source of the leak.
If it's soft and feels wet or mushy, that's a sign you need to replace your ceiling drywall.
While condensation itself isn't harmful to us, the mould that it may lead to is also terrible for our skin and lungs. Many respiratory issues can be triggered by mould spores, including asthma, bronchitis and pneumonia, as well as worsening cases of eczema and hives, for example.
Dehumidifiers seem to be the obvious way of reducing humidity, removing condensation, stopping walls becoming damp and preventing mould. But a more effective solution is to give your home a small but consistent background movement of fresh air. This will help keep your home feeling fresher, healthier and mould free.
A condensation stain tends to be in dots or blotches that can be small and many of them and sometimes they can get big and cover a large area but normally does not look like the picture above of a roof leak stain.

If your roof or ceiling leaks due to a covered peril, the associated damage should be covered under your homeowners insurance policy. Most home insurance policies have an open perils claims basis, which means unless coverage is specifically excluded, then it is included.
Moisture trapped behind plasterboard can turn to mould, causing unpleasant smells or even pose a health hazard. If you find a leak early and stop the spread before significant damage is done, it may dry up on its own. But for larger leaks it's important that the ceiling is dried out fully using a dehumidifier or fan.
Let's say you detect a leaking ceiling and took action quickly to fix the problem. In this case, the ceiling should dry out relatively quickly on its own. However, if you didn't take action right away or the leak was particularly severe, you may need to use a fan or dehumidifier to help speed up the drying process.
Call for help! Even if the water leak appears quite small, there may be more damage you can't see. If the leak is big it's probably still a good idea to call in a professional, so they can assess the wider damage.
Many indoor lighting fixtures are not designed for water exposure. As a result, electrical wires affected by or submerged in the water can develop dangerous molds or experience corrosion. These tolls on the electrical wiring can lead to electrical shorts or fires over time if they are used during or after a leak.
Be aware that if the leak is significant, there is a chance that a section of the ceiling could collapse and this will cause significant damage.
Damages do not only cost you a lot in repairs but are also a major safety hazard. Wet ceilings are one such issue. Water damage to your ceiling can cause water to accumulate there. Your and your family's health and safety is highly compromised.
Why a plumber should fix your dripping wet wall or ceiling. If your wall or ceiling is dripping with water, you'll have to get an expert out to assess the problem as soon as possible.

Other forms of damp, such as rising damp, are more likely to worsen in rainy weather. By looking at it, you can usually identify what's generating the wetness. Other forms of moisture cause a stain mark to emerge on walls, ceilings, or floors, whereas condensation tends to produce patches of mould with soft edges.
Window condensation isn't necessarily a big deal and often doesn't require attention as it generally disappears on its own. But if you're not able to easily wipe the moisture away, you might have a problem to address.
