What Customers Are Saying
The product was effective at removing algae, mold, and discoloration from roofs for many customers, especially when used as directed. However, some found it ineffective or too strong, causing damage to plants and other surfaces. The results appear to vary, with the product working well for some but not for others, particularly on heavily soiled or older roofs. Customers recommend following the instructions carefully and being patient, as the product may take time to show results.

I have recently been informed by the company not to use this product on metal roofs. There are probably many metal roof owners who use this product on their roofs. The Sparay and Forget product label does not state the product cannot be used on metal roofs. Please find another product to use for metal roofs. Today's Spray and Forget isn't the great performing metal roof cleaning product of long ago.

Doesn't work well on metal roofs
My metal roof has mold on it. I sprayed it with this product 3 times and it didn't do much. To be fair, After this failed I sprayed straight bleach on it and that only did a little better.
Thank you for your feedback. Spray and Forget Roof Cleaner is not intended for use on a metal roof.
