Several factors could result in your drywall ceiling collapsing, and unfortunately, these occurrences happen more often than one would think. The most common cause is water absorption, which results from roof leaks or overflowed bathtubs, showers, or toilets.  

Water accumulation can be fast or slow, depending on what caused the absorption. Broken pipes often result in rapid water buildup, while you'll only witness the effects of slow leaks after some time. Regardless, both these situations are dangerous, which is why it’s crucial to contact a professional as soon as you notice a leak or other water issue in your home. 

Other issues that could result in a falling ceiling include poor installation, such as a lack of or incorrect use of adhesive or incorrect installation of drywall screws, nails, or ceiling joists (i.e., spacing or depth). 

Ceiling ghosting is a type of internal defect that people tend to confuse for mold growth because it looks similar. However, ceiling ghosting is when dust particles and soot stick to the ceiling and cause a permanent stain over a period of time. 

It is possible to tell whether your ceiling has ghosting or mold growth. Ceiling ghosting can be identified by the pattern it forms. The biggest indicator of ghosting is when there are straight lines on your ceilings. These straight lines form because of the attic framing above the ceiling.  

Framing isn't as good an insulator as the surrounding fiberglass; therefore, cold spots form where the ceiling and framing touch, resulting in condensation, which the dust and soot stick to.  

Nails can come out of your ceiling for a number of reasons; however, the main one being nail pops. These are small and round disruptions you'll notice protruding out of your ceiling drywall. While this might not seem like a big deal, nail pops could be an indication of uneven foundation settling, which requires immediate professional attention.  

Foundation settling is caused by improper water drainage, soil expansion or contraction, or poor construction. Foundation settling causes the foundation of your property to shift, resulting in misaligned walls. This places increased pressure on your drywall, causing nail pops.  

Other foundation problems that can cause nail pops include uneven flooring, drywall cracks, gaps between your floors and walls, sticking windows and doors, using inferior construction materials, and cracks around the chimney.  

Plasterboard was introduced after the 1900s. Before then, professional contractors used the lath and plaster technique to finish ceilings. This method was replaced with drywall as gypsum board is less expensive and much quicker to install. 

Laths are narrow wood strips that are nailed across the stud frame or ceiling joints horizontally and then coated in plaster. These wooden strips are often made out of chestnut, oak, and larch. Laths are either riven or sawn onto a stud frame or 'studwork.'  

Plaster can be installed in two ways – it's either installed on hard surfaces, such as stone and brick, or it's plastered onto laths. When it comes to ceilings, it's installed on laths. 

If you’re on a tight budget but need to redo your ceiling, there are still possible options for you to consider. Some of the simplest and most budget-friendly ideas include: 

• Paint: This is the easiest way to add value to your property. Paint is probably the most low-budget option, but can add any type of style to your space.   
• Wallpaper: Wallpaper is another commonly used method of adding a personal touch to your space. Since you’ll only be doing your ceiling, it will be affordable.   
• Drop-ceiling tiles: Drop ceilings are commonly used in basements and are a simple way to cover ductwork. It is also an aesthetic option, allowing you to add a personal sense of style.  
• Add beams: If you want to add a sense of character to your space, beams can create a sophisticated or rustic appearance.  

If your ceiling is looking a little worse for wear, some of the easiest ways to cover it include: 

• Ceiling tiles: Ceiling tiles are easy to install and one of the best ways to transform your ceiling from ugly to beautiful. There are various methods to install tiles, so you're free to choose the one most suitable for you.   
• Drywall: You can't go wrong with covering your ceiling with drywall. It's affordable, stylish, and easy to maintain. As long as you get a professional to do the installation, it will completely transform your ceiling.   
• Paint: If your ceiling is in good condition and doesn’t have structural issues, paint is a quick fix. However, it’s essential to prepare the ceiling properly for the paint to look good.  

The cost of your ceiling will differ depending on a wide range of factors. When it comes to the type of ceiling you choose, the following are considered the most expensive on the market:  

• Coffered ceilings: These ceilings are expensive because of the intricate designs involved. They create grid-like patterns through inverted panels and decorative trim. The carpentry skills required make this one of the pricier options.   
• Custom plaster ceilings: If you request intricate patterns and designs, you’ll have to be prepared to pay higher costs because of the level of work required.   
• Wooden beam ceilings: Depending on the type of wood you choose, these ceilings can be rather costly.
