My stone-coated steel roof was installed 6 years ago and is now very dirty. The product is Dura-Loc Signature Series Continental with a light to medium color. I'm hesitant to pressure wash it to avoid damaging the coating. What is a good way to clean it? Thanks.

Dura-Loc was purchased by Gerard / Allmet so I would suggest contacting them. You may ask them about trying a product that's available called "Roof_Wash"

Gary, do you know who manufactured your roof? If you can let me know, I will connect you with someone at that company so they can help you with this prescribed procedure.

Be very very careful with cleaning any Dura Lock stone coated steel roof! Please read this thread before you attempt any cleaning of these Dura Lock roofs http://roofcleaninginstitute.org/index.php?/topic/710-defective-dura-lock-stone-coated-steel-roof/#entry6597 Here is the picture, it was not caused by the cleaning, but because some of these Dura Lock roofs were defective. The black algae we removed from this roof was hiding this granule loss!
