How to Install a Ceiling Fan on a Vaulted/Angled/Sloped Ceiling

One of the most common questions customers ask online or in the stores regarding ceiling fans is if they can be installed on a vaulted, cathedral, angled, or sloped ceiling. 

In short, almost all ceiling fans that come with a downrod can be. But, depending on the slope of the ceiling as well the overall height of the ceiling will determine how it will be installed.

The installation itself doesn't really deviate that much from a flat ceiling, save for a few details and materials we will go over in this post. To read more about how to install a ceiling fan yourself, click here for step by step instructions.

At the end of the day, you'll want a ceiling fan that hangs down no lower than 7 feet and the edge of the blades are at minimum a few feet from the edges of the wall.  This is for obvious safety, as well as give it the best air flow.

For not so steep/angled slopes, you would still need a longer downrod than what came with the fan. The key is seeing if the ceiling is finding how how much or little slope there is before installation. Height is a factor too, so refer to this chart below to find the right downrod for your fan.

So, how do you know if you ceiling is 'steep' or not? To find out, you will first need to find out the slope of your ceiling. The final say in determining how sloped a ceiling is, is if needs a longer downrod and vaulted ceiling canopy (which I can get into later), is determining if the ceiling is 34 degrees steep.

In the illustration below, this demonstrates how you can find out if your ceiling needs a longer downrod and vaulted canopy. The name brand leader in ceiling fans, Hunter, made this very handy print out. 

You can print out this paper to determine your ceiling's slope. Also, read it for more concise information regarding installing a fan on a sloped ceiling.

If your ceiling is steeper than 34 degrees, then you will need a special ceiling canopy instead of the one that came with your new fan. Failure to get one would cause the fan to not install properly on the steep ceiling.

Your local Home Depot store carries cathedral ceiling canopy kits, like the one shown below.

These are specifically made for ceilings over 34 degrees in slope, so that the downrod mounts straight down. You MUST purchase this for ceilings that steep. They are available in various finishes to match your ceiling fan.

As for the downrod height, simply measure the ceiling height and make sure the fan itself is no lower than 7 feet, or even 8 feet from the floor for high traffic areas. All of our ceiling fans with downrods come with 54 inches of lead wires, which will give you enough for most high ceiling installs.

However, we do sell downrod wiring extension kits with butt connectors, so you can get enough wires through it. Linked here and shown below, these are a must for high ceiling installs.

In terms of other lighting fixtures such as chandeliers and flush mount lights, almost all can be installed on a sloped ceiling without issues....normally. Any chains or loose hanging wires can be corrected by hanging straight down. 

It's typically only 'pipe' or rigid stems that hold the hanging fixture up are the only ones that wouldn't work on an extremely sloped ceiling.

Excellent detail Joe!

The pathway to success when installing a ceiling fan starts with assembly.

In the recent past, I was asked to produce this "How To" thread to instruct store associates "How To Install a Ceiling Fan."

While intended as instruction for associates, this video serves as a functional guide to fan assembly for all DIYers.
