I bid on a house today and the customer accepted my bid. Not being a metal or classic shingle roof I began to do a little research to make sure there are no “speacial” way to clean this style roof.
As I began to read I see that there has been a huge problem with these tiles losing the coating off of them and the loss being revealed after being cleaned.
I also found a cleaning suggestion from the manufacturer and it says to use “Wet it & Forget it” and a couple other things that have SH in it.
Should I use a 50/50 roof wash or lower “%” of SH and just see how it goes?
I will be contacting customer to see how old the roof is and see if it falls within the problem years and what manufacture made his tiles.
