Cracking noise in the ceiling at night is usually caused by a variety of factors. The most common causes include water damage, roofing issues, and house settling. In many cases, the issue can be fixed with a quick fix such as resealing your skylight or fixing an issue with your roof.
Whether your home is new or old, you may experience this phenomenon from time to time. One reason is the temperature change causes the wood in your ceiling to expand and contract, which creates strange noises, especially at night.
Why is my ceiling making cracking noises?
The cracking noises in the ceiling are a normal occurrence and generally do not mean any harm. These noises are often caused by the temperature change or the house settling.
Below are a few common causes of the problem:
Thermal expansion is the tendency of matter to change in volume in response to a change in temperature. In other words, as the temperature of an object increases, its molecules move faster and spread out. This causes the object to expand in size.
The same principle applies to materials used in the construction of houses. When the weather gets colder, these materials contract and sometimes produce cracking noises.
You can usually hear this noise when the weather is changing rapidly, for example, in the spring and fall or at night.
Water damage is another common cause of cracking noises. If there is a leak somewhere in your roof or attic, it will eventually cause water damage to your ceiling.
The water will slowly erode the wood and drywall and eventually create holes. Not only is this a costly repair, but it can also be a health hazard.

Another potential cause of such noises is an issue with your roofing system. This could be anything from a loose shingle to faulty roofing material.
Additionally, animals such as birds mice, rats, raccoons, bees, etc can often make nests in the attic, which can cause noises at night.
House settling is a natural process that all homes go through. The foundation of the house shifts and moves as the soil around it changes shape and size.
This can cause the walls, floors, and ceilings to move and create strange noises. This is particularly common in older homes that have not been properly maintained.
Poorly Fastened Subflooring
Another potential cause of this noise is a poorly fastened subflooring. If it’s not properly secured to the joists, it will eventually start to move and vibrate. This can create a lot of noise, especially when someone is walking around the house.
If you are experiencing this problem, make sure to re-secure your subflooring as soon as possible.
What are common types of ceiling noises?
- Cracking noise– It is usually a gentle sound but can be loud at times and you may feel like your ceiling is going to collapse. It is often caused by the expansion and contraction of materials in the ceiling due to temperature changes.
- Creaking – These noises are also often caused by changes in temperature. As the temperature drops, the materials in your ceiling contract and can cause the wood to rub against itself, which creates a creaking noise.
- Popping noise– It is a sudden sound that is usually short. It can be loud and make you feel like something is wrong with your ceiling. These noises are often caused by the expansion and contraction of materials, but they can also be caused by something hitting the ceiling.
- Tapping – This sound is a repetitive noise that can be caused by different things such as nails embedded into the living room floor above your ceiling, joists knocking against studs, solar heating tubes located too close to the ceiling and more.
- Banging – This noises usually come from something hitting or rubbing against the roof. This could be anything from a loose shingle to a tree branch. Moreover, strong winds can also cause them.
- Squeaking – It is usually a high-pitched sound that is heard when something rubs against another object. It can be caused by anything from the movement of the rafters to the expansion and contraction of materials in the ceiling.
- Noise From Rodents – The noise from rodents is often a scratching or scurrying sound. It is usually more noticeable at night and can be caused by anything from a nest of mice to a colony of bats.
- Bird noise – Birds in the attic can cause a lot of noise, especially at night with their wings, beaks and claws.
- Noise From Appliances – The noise from appliances is usually a humming or rattling sound. It is often caused by the vibration of the appliance or the air moving through it.
What does a settling house sound like?
A settling house is a house that has been around for a long time and the floor isn’t straight anymore. It makes cracking, groaning, or popping noises because the walls and floors are shifting.
