First thing is first - clean that roof! We thought we were going to have to replace it for a couple 1,000 dollars but we found out that there wasn't any extreme damage from the moss. It was so simple, we just shampooed and sealed the roof for 450$! For more info go to http://www.dcmetroroofcleaning.com/Home.html.
This isn't the finished product. See the far left side? That's what the whole roof looks like now! A finished product photo still to come. Stand by.
