I just wanted to try and calculate cost per roof as most every roof I will be cleaning is 2000-3000sq feet.
I am going to start out with a 100 gallon tank and can get SH bulk locally
If it requires 30 gallons of SH in a 100 gallon tank...how many roofs will I be able to do...and what will shelf life be as I don't have the luxury of having multiple roofs to do being a start up.
Depending on HOW fresh your SCH is, it will take from 30 to 40 gallons for a 2500 sq ft roof, average. Shelf life is about 14 days. As long as the SHC mix is not too old, you can often revive it by adding 10 gallons of fresh SHC. If solution is over 3 weeks old, dump out, and start over.
Yes, call me this evening from 10 pm to 12 pm Florida time, mention this board, and that yiou are a roofing guy wanting to get into roof cleaning, ok ? I get several calls a day from every wanna be in the world. I know you are serious about roof cleaning, but several are not. Chris
