We have a job to clean a synthetic slate roof. The tiles are made of rubber. I researched but could not find much on cleaning it. I found one post that stated using the standard SH roofing mix is the correct way to clean it without issues. Do you concur? Has anyone else had experience with synthetic slate?

Yes .I've done many. They look great afterwards. Use your standard slate mix. I use a 3% to 4% mix with greenwash as my surfactant.
