Our proximity to the St. Clair River creates a humid microclimate that moss thrives in. We don't just power wash it away, which can damage shingles. Our process involves a safe, EPA-approved treatment to kill the moss at the root, followed by gentle removal. We then often recommend installing zinc or copper strips along the roof ridge as a long-term preventative measure to inhibit future growth.

Inadequate ventilation traps heat and moisture in your attic. In winter, this melts snow unevenly, causing ice dams along your eaves that can force water under shingles. In summer, the excess heat bakes your shingles from below and raises cooling costs. We assess your current soffit, ridge, and gable vents and design a balanced system to promote proper airflow, protecting your roof structure and improving home energy efficiency.

Signs of moss are visible green or black growth, especially on north-facing slopes. For ventilation, look for excessive heat in the attic, ice dams in winter, or curling shingle edges. The most reliable step is to schedule a free inspection with us. We'll check your attic airflow, insulation, and roof surface to give you a clear, honest assessment of any issues and your options.
