I'm in San Diego wanting to start low pressure chem cleaning.
I'm Sean Moody owner of Fully Restored Pressure Washing out here in San Diego. I've been in the business for about 2 years and it's still looking up for me. Out here we have a lot of really dirty tile roofs. Heavy,old, caked on algae that turns our roofs green. I've been high pressure washing these roofs for about a year. While our turbo nozzles and 3500 psi do the job, I would much rather prefer using a low pressure chem set up. Out here though, nobody does it and I'm wondering why. After discovering your "apple sauce method" I am excited to give it a try. Chlorine sold over the counter out here is $6.00 for 2 gallons. I can't seem to find a supplier who sells it in bulk anywhere close by. This is the only thing holding me back from switching methods. I'm not sure how much solution I'll have to use to break up this heavy algae. To see what I am talking about go to my website at sandiegoroofcleaning.com. Let me know if you think it would be worth starting using low pressure and chems on this stuff!
To yield 100 gallons of apple sauce it would cost me about $200. This seems way too high for me to make any money. Any contacts out here?
I also want to thank all you guys for sharing so much knowledge of the trade and helping us newbies get things rolling the right way! You'll be hearing from me regularly on this chat room gleaning info and sharing war stories.
