Moss on roofs in Lachenaie is encouraged by our Quebec climate — humidity, shade from mature trees and freeze-thaw cycles create ideal conditions. The larger it grows, the more it acts like a sponge, retaining water against your shingles.
🔬 Why sodium hypochlorite (SH)?
SH is the only product recognized by shingle manufacturers (IKO, BP, CertainTeed) to safely and permanently eliminate organic stains on roofs. Combined with a professional surfactant, it penetrates protective sheaths and destroys organisms at the root. Results last 3 to 5 years.
