Depending on roof material, it is recommended to use a little wider jet than what you would use on cement. Example instead of 15 degree jets use 25 degree jets so to spread out the spray pattern. The gallons per minute rating on the pump would be cut in half per jet (2 jets per machine.) For example a 5 gpm pump would use 25025 jets.
