As summer rolls around, homeowners often look for ways to cool their homes down. While this is understandable, it’s important to separate the myths from the facts when it comes to cooling solutions.

For example, does installing a sprinkler on your roof actually help cool your house? To answer this question, let’s take a look at what the experts have to say.

Is It Effective?

The experts have found that aside from watering your garden or cooling off your pets, a regular sprinkler won’t have any significant impact on interior temperatures.

This is because sprinklers are designed to work with gravity and water pressure to generate an even spray of water across large surfaces like lawns and gardens.

The same can’t be said for rooftops – since they are sloped, any water sprayed onto them will immediately run off without doing much good in terms of cooling things down.

What About Hot Pipes?

Another myth associated with sprinklers on roofs is that hot pipes will become cooler if you install them there. The truth is that hot pipes don’t need to be cooled; they just need more efficient insulation so heat doesn’t escape into the atmosphere as quickly.

If you want to achieve optimal cooling results from your sprinkler system, make sure you choose the right pipes and nozzles size to ensure efficient delivery of water across your home.

Alternative Ways For Cooling Down Your Home

Cooling a house may seem like an insurmountable task, but it doesn’t have to be so hysterical. Installing window shades is one way that can help reduce heat gain through windows during warm days – as much as 77 percent of solar heat gain can be blocked by using exterior window shades!

Additionally, installing ceiling fans or air conditioning units is also a great way for reducing indoor temperatures during hot summers.

And lastly, using reflective roof coatings such as light-colored paint can also help reflect sunlight away from your home and prevent direct heating of interior surfaces.


Cooling a house may seem like an insurmountable task, but it doesn’t have to be so hysterical.

Installing a sprinkler on the roof of your house might not be effective in cooling it down significantly but there are many other options available such as using fans and air conditioners that can help keep temperatures bearable during warm weather months.
