Sprinkler on the roof for cooling.

One study indicates that water use is around 100 gallons per day per 1000 sqft of roof area. Local fire agencies agree that the only time a sprinkler system on the roof may be advisable is if you have a combustible wood roof. This effect creates an effect equivalent of r 7 roof insulation during the day.

Roof sprinklers work by spraying water at predetermined intervals on a roof s surface. Yes you can spray your roof to help cool it down but that will only cool the shingles for a short time and be a large waste of water. This cooling reverses the heat flow through the roof. 1 gallon of water consumes 8000 btu as it evaporates.

As the water evaporates it cools the roof and helps to lower the temperature of the roof tiles and the ceiling cavity beneath it. Yes water on the roof will help cool it. This multipurpose portable tool is primarily made to protect your property from ember attack but can also be used as irrigation for garden and lawns as well as cooling your roof or misting your patio and as an entertainment for kids on a hot days of summer.

It uses about 500 watts for a 1300 sq.

We have an evaporative cooler and ac but the humidity is low enough about 25 days a month to stick to the swamp cooler. These types of systems can also be set up to operate automatically either on a timer or connected to an automatic temperature sensor which triggers the system whenever it gets too hot. Heat is now transferred out of the building through the roof. Also called an evaporative cooling system a roof misting system lowers surface temperatures by spraying an extremely small amount of water across the roof allowing the water to cool the roof as it evaporates.

These systems provide cooling by spraying the water evaporates and cools the surface. It is also foreseeable that an owner can use the embers sprinkler system to wet the rooftop of houses on a hot day to cool down the house for general irrigation purposes or wet summer fun.
