I have a question about roofs. How do you apply you chemical and how do you rinse (top to bottom or bottom to top)?
I would think that the chemical should be applied from the bottom to top to avoid streaks. I would then think that it would be best to rinse from the top down so that you don't have to re-rinse everything and I would also think it would be safer as you are not walking on so much chemical.
What I'm think is... Apply chemical to one half from the bottom up then do the other side. The first side will be dwelling while you apply to the other side, then just go back and rinse.
Is this what you guys do?
