Have to agree on dont BLAST any roof.LOL Sounds like you have a 8/12 pitch roof or greater, are you working with composite shingles? You should use extensions off your washer LOW pressure where you can stand on the ground. There is a sprayer on wheels that you use to wash off your chemical can use it to apply as well. I never walk most roofs unless they are 4/12 pitch or less. Unless you have saftey lines rigged then you have the chance of damage to the roof loose shingles ect. |
