Roof Moss and Gutter Treatment

We begin by agitating any large clumps of moss with a stiff brush. Then we blow all the loose debris off the roof with a commercial grade backpack blower. We clear all the debris from the inside of the gutters and check that all the downspouts are clear.

We then apply granular zinc sulfate to the roof to kill any remaining moss. Zinc sulfate is cost effective and kills all moss within one month. It is EPA approved and won't harm your plants or siding. Rain and wind naturally wash away remaining dead moss.

Note: We use a liquid moss treatment for cleaning roofs that are particularaly steep or difficult to access.
