Moss growing on roofs in Laval-Ouest thrives in shaded and humid areas, conditions very common in our region. It infiltrates under shingles, lifts their edges and creates paths for water. Our SH treatment in Laval-Ouest destroys moss and its rhizines in depth. Unlike mechanical scraping or high pressure which only move the problem, SH kills the organism chemically. Result: moss doesn't grow back for 3 to 5 years.
