I recommend a 4% mix, that’s generally what I would use. For example if your starting off with 10% SH strength and need 10 gallons you would mix 4 gallons of SH and 6 gallons of water with a compatable surfactant that I would adjust depending on the pitch of the roof for more stick. Always remember to heavily rinse the bushes and plants (don’t be shy, waters cheap) and do a good post rinse of same area. Very easy to do, and very important that you pre rinse and post rinse plants if you haven’t got much experience with controlling overspray. Rinse your gear afterwards aswel. Can’t go wrong.
