Shurflo type chem set-up

[Minuteman]

I need a chem set-up that will get undiluted chemical to spray out of the end of a 200' line. If I am walking a roof and spraying from the peak to the gutter while standing at the peak, and the motor and chem is in my truck 200' away, what type of set-up would I need?

30+ gallon chem tank
200 feet of doubel braided clear hose - diameter??(1/4 or 3/8)
Shurflo pump psi? GPM?
Lance - tree sprayer, stainless, etc.?
Deep cycle marine battery type?

Roofs are normally cleaned from the gutter upward to reduce run-off. Spraying from the peak downward will add to the run-off/overspray and create problems with plant/grass burn.

Don't you apply chems from the gutter to the top of the roof and rinse from the top of the roof to the gutter?

My question was more about the Shurflo pump than application. Some people use 30' extension lances, some use 50' of hose and move thier chem and pump often, I however would rather have a strong pump with 200' of hose and never have to move the pump.

Since a lot of people do roofs I woul dlike to hear what types of set-ups most have to get chem undiluted onto the roof.
