Dicor is the company EDPM roof is the product. They also make a few other roofs.
When I got my house.... The advice for roof care was a lot like kitchen floor. Mop, Bucket, Spic-&-Span, water. And that is what I use today.
Then Dicor came out with it's own line of roof care products, more costly of course, I do not believe they are better, but.. Feel free to believe differently than I do.. Many go to the same church as I, Many go to a different church or rather churches (And that folks is the limit of my "religion" posts for today) I am not prepared to say who is right.
