Roof Cleaning Products – Too Many Choices
So I've got black roof stains but there are so many roof cleaning products to choose from, it can be overwhelming. The thing I'm concerned about is that most of them seem only to be effective when used in conjunction with a pressure washer, and I'm not comfortable blasting my shingles with high pressure. Others say you can just spray their product on the roof a few times over the course of a month and then within six months to a year all the stains will be gone, but, seriously, who wants to wait six months for something to come clean? I'm hearing good things about non-pressure bleach application, though, so I'm looking more into that. Seems that there are more and more roof cleaning contractors popping up these days so I plan on talking to a few of the bleach guys and getting some numbers. Besides, I don't much fancy hopping up on my slippery, chemical-covered roof anyway.
