Answer 2

This is a two step process.

First, kill the existing moss by spraying it with a bleach/water solution, then rinsing the roof thoroughly. However, it is always a good idea to check with the manufacturer of your shingles to make sure this is suitable for the type of roofing you have.

Second, prevent moss from returning by installing zinc strips under the shingles near the ridge of the roof. You should leave this work to a professional because it involves working on the roof. Here's a short video explaining the process:
