Moss control

Asked May 9, 2016, 6:04 PM EDT

I have been battling moss build-up on our tile roof for years. Now the lawn is overwhelmed with moss. I hear cryptocidal soap kills moss; is this true, and if not, what do your recommend for both the roof and the lawn? If you do recommend the cryptocidal soap, where can I buy it and how much should I use? Thank you.
