Installing a swamp cooler on a roof can be a bit tricky, but it's doable with some basic knowledge and the right tools. The first step is to identify the spot on your roof where you want to install the unit. You'll need to make sure there's enough clearance for the fan and that the spot is free of trees, power lines, or other obstructions.Once you've chosen a spot, you'll need to confirm that your roof can support the weight of the swamp cooler. If it's not already installed, you'll also need to install a mist system to provide moisture for the cooler. Once everything is in place, simply follow the manufacturer's instructions for installing your specific model of swamp cooler.

A mist system can be installed on a roof in one of two ways: 1. By running the tubing for the mist system along the roof and then up the side of the building to the swamp cooler unit. 2. By running a small duct from the roof to the inside of the swamp cooler unit. Whichever way is chosen, it is important to make sure that there is proper ventilation so that hot air does not buildup around the swamp cooler unit.
