Who waters there house to cool off?

A misting system on the roof sounds like a good idea...
Capture the run-off from the gutters in a barrel.
Then reculate it.......
Sounds like a business plan to me.....

I don't have gutters over my hedges heck the run off can water the bushes that I water anyway.... Win win

Hmm, a 12 volt battery recharged by solar panel with a bildge pump and a timer. Man were on to something here I think!

When I ran the lumber mill in Livingston , the first summer I was aghast at how hot it was. I come from the chemical plant background, and to me the conditions were unsafe to work in. We had sprinklers for the logs to keep them from ruining, but I couldn't even get the funds from corporate for some porta-cool units. So instead of sitting around my air conditioned office I started building sprinkler sets for the roof. Metal roof was Africa hot in the summer. I tied it in to the log sprinklers, had one of the guys lift me in the bucket, and ran the lines. It dropped the temp by at least 30 degrees. Plus, the evaporative cooling effect even made the light breeze that came through nice and cool. I put a mister system around my outside compressor to cool the air going in, and it dropped my electric bill a bunch. You have to try and keep as much moisture as possible off the units, and only cool the air around them.

I have a misting system on the back side of my house. The back wall is west facing and gets super hot. The mister really cools it off and makes the AC inside run a lot less. Plus it helps water and keep the outside plants and my deck and patio cool. Bought the system at Lowes.

I do it works pretty good

honestly never thought about this but it sounds like a great idea, makes perfect sense to me!

We have a tin covered patio out at the ranch house, it has honey suckle vines growing down one side, we put a sprinkler on the roof and it feels just like the old swamp boxes, pretty awesome sitting out there in August having a beer listening to the sounds of sprinkler water hitting the roof.

I did it at the last house...(ceilings faced east/west with vaulted under-insulated west ceiling that had about a foot between roofline and inner ceiling).
set a sprinkler to rain on that roof line , dropped the temp about 10-15 degrees...

I changed to energy saving screens for the exterior of all the windows on the house and have black out curtains on the inside. Made a big difference on my electric bill and house stays cooler.

You may change the surface temp of your roof for a few minutes, but it's still gonna be hot in your attic. Best thing to do is create air flow through the attic with eve and/or soffit vents.

I would think you would have the same effect on the brick as well. That clay has a lot of thermal mass so wetting one side isn't necessarily going to cool it all the way thru a 4" brick.

I have to agree w/this. On a trailer home it may work but on an ordinary construction home, I don't see how it could possibly work unless you ran the water ALL day long. & that would cost more than running the AC.

that's where I was also. but I have very little knowledge in this area. I do like the misting system on patio's though.

My wife taught me about this in the first rent house we lived in. I grew up in a well insulated house with shade trees so I had no clue. The first house we lived in had virtually no insulation in the walls and the outside was some sort of hardy plank type stuff. It helped tremendously if we waited until after 7 pm to do it.

Growing up my Dad would tell me to go spray the house with the water hose. I still do it today. Sometimes I will spray my truck down before I leave to go on a trip or if it is really hot outside. It helps cool it off.
