A vaulted ceiling is a great way to give your room a vintage look and make it appear larger than it really is. Unfortunately, the problems with vaulted ceilings tend to far outnumber the advantages.
Problem 1 - Poor Climate Control
Air conditioning is a big problem, as warm air tends to gather up in the cavity, which in turn forces the AC to work overtime to keep that area cool.
Problem 2 - Difficulty Installing Fixtures
Second, given the structure of the ceiling, installing lights and fans in the ceiling becomes an uphill task for the homeowner.
Problem 3 - Difficult Maintenance and Cleaning
Finally, when dirt and cobwebs form in the corners of the ceiling, they are very difficult to reach.
