Moss and Zinc Strips, Part 2: Is moss on a roof just cosmetic?
Not always.
During this inspection, Peter found moss that was beginning to lift shingles away from the roof surface. As moss grows, it can trap moisture, separate roofing materials, and expose areas that are supposed to stay protected.
One of the reasons moss gets our attention isn't how it looks—it's what it can do over time.
Peter also points out the zinc strips installed on this roof. They help slow moss growth, but their effectiveness only reaches so far. In our North Idaho climate, moss often returns in the areas beyond that protection.
The bigger takeaway from this inspection:
Moss isn't just changing the appearance of the roof. It can contribute to premature roof wear and shorten the life of the roofing system.
