Signs and Causes of Damaged Ceiling Plaster

If the plaster ceiling in a room shows signs of damage, you'll either need to organise repairs or a plaster ceiling replacement. Look out for the symptoms listed below, and also consider the following list of things that cause damage in the first place.

Signs of Ceiling Issues

Symptoms to watch for include sagging plasterboard, which you can test by measuring the ceiling height where it meets the wall and also in the room centre. Alternatively, a spirit level held up to the ceiling will reveal sloping. 

Other symptoms of problems include mould and mildew growth and dark, damp patches. Or you might notice visual cracks along the ceiling or else hear cracking noises. Finally, a line of button-size circles shows that the plasterboard has fallen away from the ceiling joists or timber beams that it attaches to. If you notice any of these warning signs, you should call an expert to assess the situation. If you're wondering what preventative measures you can take in the future to prevent issues, consider the following causes.

Causes of Ceiling Problems Roof Leaks

Leaky roof cladding such as cracked tiles or rusty metal sheets can allow rainwater into the roof cavity where it can soak into the ceiling insulation and plaster. This moisture can cause mould and mildew to develop. Plus, heavy, soggy insulation can stress the plaster and drag it away from the ceiling joists.

Storing Items in the Roof Cavity

Ceiling plaster is designed with adequate strength to hold up items such as light fittings and to bear the weight of insulation. For this reason, you shouldn't store items in the ceiling cavity as the plaster could give way and spontaneously collapse if the weight grows too heavy for it to bear.

Working in the Crawl Space

You may have ducted air conditioning, which contractors require access to, or electricians might need to work in the roof cavity. Typically, they'll put weight on the beams and ceiling joists, which can carry more mass than the plaster itself. However, if someone accidentally steps on the unsupported section of plasterboard, it can pull away from the attachments.

To keep everyone safe and avoid a spontaneous ceiling collapse, take any damage signs to heart and call for an inspection. Sagging, cracking, mould and mildew are common indications of weaknesses. 

By being proactive, you can avoid damage in the first place. Ensure your roof cladding is watertight to prevent moisture from wreaking havoc. Plus, don't stack storage in the crawl space to avoid undue pressure on the plasterboard.
