I know you all probably hate these threads but… in process of my first roof wash at my own house. The roof is covered with lichen, pitch is too steep to walk and metal roof/composite decking below.
This was my first roof ever, a bit of a challenge to begin with. I currently have 3 hours into it, only half finished rinsing.
I sprayed the roof using a 4 gallon backpack sprayer, 6% sh mix with gain a surfactant. I let the mix dwell for 24 hours and starting rinsing today with my 4gm pressure washer using the “garden hose on steroids” jrod tip. I did see a small amount of granules lost on the ground but I would imagine to expect it with this much lichen.
This was really a testament of if I want to add roof washing to my business. I will be investing in a Fatboy once I can cover the expense.
Roughly speaking what ballpark range would you have charged for this roof?
You should include the size of the roof and where you are located in your post. That plays a role. If someone tells you what they would charge and they’re not located in your city or state it’s somewhat irrelevant.
From what I just read you need to do a good amount of research on here before you consider offering roof washing. Everything you need to know is on here so just search and you’ll learn how to do it correctly. Keep that SH off of your back btw.
Ok so in va that roof would be about 600. But more importantly did you do any research before you tried to wash the roof. Never ever ever put chemicals like we use in a backpack sprayer.
It’s a backpack sprayer designed for bleach by Chapin. I have done plenty of research, this was just getting some experience before pulling the trigger on a 12v system. The house is 2000 sqft and in northern NJ.
Ok NEVER USE A BACKPACK SPRAYER. If you have any questions about that google what happens when they malfunction. Or gain for that matter how much research did you really do
Or, just ask me. I had a 2% mix run down my arm and down my back and into, yep, you guessed it–my butt crack. That low of a mix didn’t do anything to my arm or back but my brown eye was ON FIRE for two days. You know what the worst part was? The first shower. When the water hit my poop chute it felt like someone stuck a branding iron up there.
Okay thank you for the concern about the backpack, I will not use it again. Figured for one time on my own house it was a better idea than jumping $1700 into a Fatboy. I used gain just to test it with full understanding roofsnot is a superior surfactant. Appreciate all of the constructive criticism.
You can build a good 12v system for much less than $1700. Whether you decide to do roofs or not you should definitely get some sort of direct application method so that you can do stucco, brick and heavily soiled concrete. It’s not just for roofs.
