This works! It fully kills the moss on my shingles. But you need to take a stiff bristled broom and scrub off the moss first. THEN sprinkle this on the mossy areas to kill the spores.

Great product!

We were recommended this from a contractor. It works very well! Just make sure it's applied a few days before any rain to get the best results.
