I really liked the video. I think info like that is priceless. I am the type of learner I can read 1000 hrs but seeing something done I can learn instantly. Thanks again

Scott, I would have needed a 40’ ladder to get to the top of the roof from the side of the house. I only have a 24’ It is hard to see in the video, the house has a cape cod style roof with about a 10/12 pitch. Your not walking that. Thank you for your input. As always I appreciate and learn from all input here.

Good luck with the video Dejay, I used a flip cam, about the size of a cell phone.

 Michael, it was all love. that was the 2nd applacation. I changed the tip size the closer I got to the bottom.

Apple Cider with Dawn, 00 to reach the top and 1/4 meg 4030 as I got closer to the bottom

Here is a video I made while I was cleaning a roof the other day. I read a thread about run off, So I thought I would try out what I learned and make a movie. Now before you criticize the quality of the video, remember, I am on a ladder with a Respirator on, safety goggles that are fogged up because I am sweating, Plastic rain pants on so I don’t burn my legs because I am on a ladder.
Now, did I forget anything?
Oh yeah, I love my job.

Glen.  Great video considering you are recording it with all that  gear (mask, suit, gloves) and while spraying the roof.  Did you wash both sides or just the one side?  How did it come out?  Seeing the end result would have been a great way to end the clip... 

 

glad to know that was the second application, looked like you we cleaning a clean roof! lol

From the bottom up or the top down it is all about how you can control that runoff. Way to take my posts and put it into practice Glen!! Not every roof is done the same here. Sometimes we use the ladder edge, sometimes we get up top.
We usually go from the top down as the video by Glen shows.
Sometimes we spray just the gutter line 2-3ft up with a light enough spray to not have many drips, then bring it down from the top and meet that line. Then we lightly re-coat the whole thing. This was taught to me by Chris Tuckers Son.

There are many ways to control runoff and as an owner operator you can get there with practice.
Having employees changes the way this works.
I am starting to be sold on providing employees with less flow and weaker mix to decrease their chances of accidents and extreme runoff. That is why electric pumps are still great for roof cleaning even though they have issues air does not, Air has issue electric does not also.
Troubleshooting an air system is much more complicated than just changing out a throw away electric pump. The electric pumps can be manufactured to produce much less gpm making it safer for employees and reducing your chance of having to deal with a heavy sprayer on your team.
