First Metal Roof

Did my first metal roof today…

Ill have to resize these midget pictures…





Hello, I’m fairly new to the forum lots of great info here. I have a metal roof to clean similar to the one you cleaned per the pictures posted. Could you share your insight in regards to the chemicals you used? So far I have read that SH will do the trick along with a surfactant similar to the house washing mix. My concern is will the use of SH in anyway harm the sheet metal, along with its screws? Any help would be greatly appreciated, thanks. By the way you did an awesome job.

If you’re killing algea, SH will work fine. It won’t hurt the metal. Be prepared to actually spend a bit lf time spraying, not always a soak and rinse scenario.

Thanks for the advice, I really appreciate it. The job was rescheduled for the beginning of next month. Will post pictures once completed. Thanks again for your help
