I believe that, rather than collecting coolth, he is trying to reduce the infiltration of heat during the day. He is not trying to collect the runoff water, which has been heated, not cooled. It doesn't cool the house, but just reduces the solar heating. It would be more effective if you have minimal ceiling insulation and minimal venting between the insulation and the roof (as is often the case in many "flat" roof houses).
You are correct, Kind Sir.
You are again correct, Kind Sir.
Not the case. Standard-looking gable roof, R-30 insulation. Little exhaust fan doesn't cool crawl-space much. Whole-house fan is not used except late at nite and very early in the morn.
I'm still inclined to think that drastic reduction of solar heat on roof surface would be very helpful.
Lots of folks water their lawns/gardens. I just wanna water my po' scorchingly-hot roof. :-)
Anybody got ideas on how to mount, say, 2 sprinklers and a hose on a gable roof without piercing any shingles?

****************************************************** *** Puddin' Man PuddingDotMan at GmailDotCom *** ******************************************************;you might try finding insulating materials to stuff in your attic ( any excess could be stuffed up Raid's "grand canyon". Also you might attack a pinhole orafice ( trying different sizes till you get good cooling with a minium af water ) to a hose and put it on the suction side of a fan, it takes alot of heat energy to change liquid water to gaseous water, much more than you might think. Or you might use a wetted cloth, but it would reduce airflow and might be hard to keep properly wetted. There are commercial units like for industrial spaces that that make great claims. good luck
You mean we let you in to Canada? After all those things being said about 'furriners' and 'illegal migrants'. I guess we must like you spending those strong (i.e. expensive) US dollars. Fishing must be better up here?
However; springing to the defence of any/all Canadians, since we ARE a multicultural/multi-ethic country; that comment could be construed as racist; on two counts.
At very least iyt is not nice and stereotypes a whole group.
It does not belong on this 'Home repair group' any more than a Canadian commenting, here, on say Iraq or Viet Nam. There other more suitable forums for that.
Unfortunately we are, on occasion, being told how to think by our more numerous cousins in that smaller country to our south! No; not Mexico, amigo. How would Americans like it if other nations used an expression such as, "Those know it all Yanks"?
With the present air of protectionism and being in a state of siege within the borders of the USA we understand that you must make sure you have your American passport to get back into the "Good O'l US of A"?

PS. If your friends can't make a comment who can? No ill will intended.
In Spain & Portugal, stallholders use water running down the canvas stall canopies, collect the water in a tank and pump it up again. It really does cool it underneath. That is a fabric tent like roof. It must make a difference on any roof though. How much, well I don't know.
Heavy insulation to keep the heat out must be a good thing.
In some cases spraying water on your a/c will benefit performance however it can cause the system to over condense resulting in low head pressure causing evaporator to frost over doing more harm than good.
Shut off power supply to condenser and try washing out coil carefully not to bend coil fins
sounds a bit like a >>desert cooler news: snipped-for-privacy@news.west.earthlink.net...
Sorry; I am sure you didn't need that.

Begone, inimical troll.

Good now we have heard from the alt.hvac Troll and give out his fool words for today.

I lived in a 14 X 70 house trailer w/ heat pump air/heat.
I discovered the first summer that just a simple $10.00 oscillating water sprinkler on the roof durring the hottest part of the day worked wonders ( gave the kids something to play under also).

It would be easier for you to live in your basement during the summer.
Plant trees around the house. In 10 years from now when you go insane from the heat the house will have lots of shade.
You might collect the water in a pool with a $40 400'x1/2" pipe spiral to preheat water for showers...

Here in Florida your roof would be covered with an ugly thick coat of gunky, slippery green slime (mildew? algae?) in about a month.

Tell me about it.
I spent most of the aftnoons down there on hot days last summer.
But I can't move everything down there ...

****************************************************** *** Puddin' Man PuddingDotMan at GmailDotCom *** ******************************************************;
Yeah, there's an exhaust fan up there ...
I dunno anybody understands. On a clear 90+ degree day, the shingles get more-or-less too hot to touch. I can direct the garden hose on 'em and the steam just rolls off ...
I think it's the extreme heat that fries the shingles (dries 'em out, curls 'em, etc). Will assume that they'd last longer 'till I have evidence to the contrary.
Still haven't figgered how to rig a cheap system. Can't be too obvious or expensive: water dept. may well shut me down.
