Moss and Algae Removal + Treatment
Moss is a simple plant growth that thrives in damp, shaded locations. It is usually found on north slopes of roofs and roofs shaded by overhanging trees. You can control moss by removing overhanging tree branches, scraping away as much moss as possible, and spraying with our de-moss spray.
Spraying works best when moss is actively growing and when rain is not likely for several days. Moss grows rapidly in rainy weather.
Our application has been known to control mosses for 2 to 5 years and spraying application may need to be applied every 3 to 5 years, (depending on location, surrounding trees, ect.). Our professionals remove excessive moss from the roof by hand and then spray the roof (weather permitting). Holland Services uses a liquified zinc sulphate in our applications.
Buildup of moss on roofs erodes the surface, lifts shingles, and absorbs moisture that promotes decay and leakage. Our moss removal spray quickly kills the current growth and any new spores such as moss, algae, lichen, etc, and can be sprayed on wood shakes, shingles, tile roofs and any surface that promotes growth.
Our procedure is safe for ALL roof types.
