We use 3/4 inch ball valves.
I have never tried the new 1/2 inch udor spray gun http://www.pressurewasherproducts.com/Roof_Cleaners_Corner.html
It look interesting ??

Only used the 3/4 ball valve.  I've never tried the gun.

the gun will be great for what i do most barrel tile with no gutters so runoff is the biggest concern but ill still use the ball valve for shingle or houses with gutters but i dont get those to often i wish i did the are so much easier and take alot less time to clean

I use the 3/4" ball valves also.

I tried the 1/2" poly gun and didn't like it. It was too weak, would not shoot as far, constricting the flow. It also didn't last, the trigger would stick.

If you like guns try Home depot's industrial garden gun with an adapter, bushing, and a stainless steel coupler with Lori's stainless steel tri-nozzle holder. It works good.

Roof Clean USA uses the Udor Gun and the 3/4" Ball Valve in both HD poly and in HDPE.

You can also find the 3/4" Ball Valves in Kynar (hard to get and expensive but lasts forever)


Personally, I like the qualities of both, the use in roof cleaning chemical applications for both is that each do certain things very well.

The ball valve is great for FLOW and GO! there is no worry of hand cramps as all you do is turn on the valve and go to town, but on occasions when you are in awkward positions it can be combersome.


That is when the Udor gun comes in very handy. With the UDOR gun, you can control flow with ULTRA fine precision, which means, shooting around dormers and cut up roofs with lots of eves and overhangs is much easier for me to shoot with more control and LESS runoff.
