We follow the only process that the Asphalt Roof Manufacturers recommend, which is to softwash the roof or “treat” it with a liquid solution that will completely kill the moss. Proper precautions are taken to prevent damage and control overspray.

1. We start with our plant protection process in which we go around the home and pre-wet all plants and areas that could be exposed to overspray. We look at where the gutter downspouts flow and bag them if necessary.
2. We softly broom down some of the thicker and heavier moss. (less is more as we don’t want to get too abrasive with the roof, but we do want to remove some of it if possible as this will make treatment easier)
3. We use a blower to blow off the roof and as much of the moss as we can.
4. A full cleanup is done and usually gutters are cleaned (we always recommend having your gutters cleaned if the moss is thick and clumpy as some of it will broom down and we don’t want it to clog the downspouts)
5. The roof is then treated with our liquid solution. One technician usually operates the spray while one follows below on the ground keeping plants and property wet and diluted to any overspray. 
6. We water all plants before, during, and after.
7. The remaining moss on the roof is now dead and over the next few weeks will begin to decompose and weather down with the rain. In approximately 6-8 months, the remaining moss will be gone.
