Moss growth on roof — Chicago, Illinois
Moss thrives on north-facing or shaded roof surfaces where moisture lingers. While it looks harmless, moss roots work under shingle edges, lifting them and allowing water to penetrate the underlayment. Over time this leads to wood rot in the decking, leaks, and shortened roof lifespan. Pressure washing can damage shingles, so professional moss removal uses gentle chemical treatments, manual scraping, and zinc or copper strip installation to prevent regrowth. A roofer can assess the extent of damage, safely remove the moss, treat the surface, and recommend ongoing prevention.
