Eco-Friendly Ways to Keep a Metal Carport Cooler in the Summer

If not protected, metal carport will inevitably get hot under the summer sun. However, there are several ways that you can keep the carport cooler during the warmer months. Consider the following ways to protect your metal carport from the heat.


One of your most effective tools in this scenario is shade. If you are just putting up the carport, pay close attention to how much shade it will get. If you have a wooded area close by or even a single tree, consider putting the carport close to it. The tree will provide ample shade for the metal surface. By keeping the direct sunlight off of the carport, you will be able to keep the metal much cooler. You could also place the carport close to the house as the structure of the house could provide some shade at certain times of the day. 


Another option is to paint the surface of the carport. When you do this, make sure that you are using a water-based paint instead of an oil-based paint. Water-based paint is much better for the environment and will be just as effective.

When you paint a metal carport, you need to use a light color—not black, brown or any dark color that will absorb the rays from the sun. Opt for a light color like white or cream to reflect a lot of the sunlight, not absorb it. This will significantly lower the temperature of the metal and keep it cool throughout the summer.

The paint can also play a vital role in helping the metal structure to keep from rusting. When metal is exposed to water, it is susceptible to rust, so make sure to use a rust inhibitor paint for this project.

Water Sprinkler

Another way that you can keep your metal carport cooler is to periodically spray it with water. In fact, you may have a sprinkler out during the summer anyway. You do not need to run the water for too long for it to be effective. If you leave the water on too long, you will waste a significant amount of water, which is not good for the environment. However, by using water to keep the metal roof cool, you will not have to use any chemicals or anything else that is bad for the environment. Turn on the sprinkler and let it shoot up onto the metal roof. You only need to do this for a few minutes during the hottest part of the day to make a big difference.
