The Roof Cleaning Institute Of America Training & Certification Forum
"Find A Certified Roof Cleaner Directory"

Hey guys, before there was RCIA, there was this Roof Cleaning Forum
There is not a whole lot of info there, since we moved to this Forum.
However, it is Indexed and crawled regularly by both Google and Yahoo, and it is an old URL. It will provide a free, highly relavant back link for your web sites if you are wise enough to make a few posts on it.
I left it up purposely, as I could see where it would come in handy one day as a tool to improve our guys web sites search engine performance.
