As I've tried to point out in previous posts, roof cleaning can be a dangerous endeavor, especially for those that don't know what they're doing or that don't take the proper precautions. If you need further proof just take a look at this article in the St. Petersburg Times about a roof cleaning chemical explosion that sent one man to the hospital and put a two-foot wide hole in the roof. No matter what roof cleaning chemicals, products, or procedures you use, the most important thing is that you take your time, assess all the risks, and pay attention to any directions for use.
On top of the risks associated with misuse of chemicals, you also need to be cognizant of the fact that being up on a roof or ladder is of course very dangerous! I once saw a guy scaling his steep roof in an effort to clean it with the latest fad roof cleaning product, and he was wearing flip-flops! I could hardly believe my eyes. You're going to put your life in the hands of a $2 pair of Wal-Mart flip-flops?! Unbelievable.
I've said it before and I'll say it again that your best bet is to hire a reputable, experienced roof-cleaning company to take care of it for you. They already have the proper equipment, chemicals, and safety procedures in place so that you and your family can remain firmly and safely on the ground. Preferably, you'd find one that specializes in no-pressure roof cleaning.
My name is Scott and I started this site in 2008 to educate the public about roof cleaning. It's come a long way since then.
our apartment complex has been cleaning roofs this month. we came home one day to a guy above our door spraying a blue roof cleaning chemical on the roof. he did not stop spraying as we walked by and we were misted (he could see us), before we got into our apartment he had moved to spray above out door and sprayed us pretty good. should we be worried about what this guy sprayed us with and should we talk to our apartment managers about this? i’m a little concerned about it. thank you
