Naw, just a bunch of roof guys talking shop
We all use what we like, just like you do
I am cleaning a roof in the first pic, second is Mallard, third pic is one of my expolyees, and you are cleaning a roof in the 4th picture.
For those curious about hose, this is a good example.
The second picture is a Mallard Person using the same pump as Squirtgun is using in the last picture, a Shurflo.Mallard had 44 trucks in their day, and all used small shurflo 12 volt pumps.
Look at the difference in Flow ?
SOME feel that big hose "causes" more run off ?
MY opinion is that operator skill controls run off.
With a big pump/big hose, you simply move faster.
In picture one, that is me using a 20 GPM John Blue Pump.
SEE any run off ?
Just as some can not handle a really fast Motorcycle, some can't handle big hose and big pumps.
Smaller hose and smaller pumps work for them.
Plenty of roofs have been cleaned with smaller diameter hose and small pumps.
Just not nearly as fast as those of us with faster equipment.
95 percent on my work is JUST roof cleaning.
My guys do several roofs a day.
Having a fast roof cleaning set up is important to me.
If you just do a roof every now and then, you may like the space and cost savings of a slower set up ?
The Astute (Chris' word) will notice I am rinsing the roof with a ball valve and the pressure washer.
Run off wasn't a concern due to having a well trained ground person.
