Moss growing on roofs in Lavaltrie 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 Lavaltrie 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.
