The Chapin Tree/Turf Pro Backpack sprayer is like any other hand pump sprayer, it typically will only reach about 10+ feet under pressure. Probably not enough to reach your roof line. We do carry another sprayer called a Slide Pump Sprayer that will reach up to 30 feet or more. There is a video on the slide pump sprayer page that shows it in action so you can see how it works. The slide pump sprayer is the only type of non gas or electric sprayer that will reach that far.

The Chapin Tree/Turf Pro 4 Gallon BackPack Sprayer (#62000) requires that you pump continuously while you spray. This type of sprayer will not hold pressure like regular hand held pump sprayers. You do not have to take the sprayer off to pump it.
