Hello, I'm totally new to these type of low sloping "rubber" roofs and wanted to know the best way to handle my problem. Our inspector suggested putting gutters all around and didn't seem to know much about it himself. But our roof already has a drainage system but seems to have been muddled by a previous owner. Now the water just runs over the edge of the roof instead of draining correctly. Is there supposed to be a channel where the water collects? (You can see a small drain hole in the bottom picture) If someone can give me an idea of how this is supposed look I would be thankful. Any pics you can point me to? Also, does this look like the EPDM type?
