Valley leaks
Where two roof slopes meet
Black streaking on a roof is algae, and the moss that follows it holds moisture against the shingle and works into the gaps between courses. Both shorten service life, so cleaning is maintenance rather than cosmetics. The method matters: soft washing with the correct solution lifts growth without damage, while pressure washing strips the granules off and takes years off the covering in an afternoon.
Coffee County is far enough south to take the inland remnants of Gulf and Atlantic hurricane systems, and that is the storm profile that matters here. By the time these systems reach Coffee County the wind has dropped below the headline numbers but is still sustained for hours, which does something different to a roof than a short violent gust — it works shingle tabs loose over an extended period and drives rain horizontally under courses that would shed a normal downpour. The heat and humidity do the rest. Roofs here run hot for most of the year, which ages the shingle and hardens every rubber and sealant component, and the humidity means anything that gets wet inside the roof stays wet.
It should not be. Pressure strips the mineral granules that protect the asphalt mat, which is the single fastest way to take years off a roof. Soft washing achieves the same result without the damage.
Where shade and moisture allow it, yes. Zinc or copper strips near the ridge release trace metal in rainwater that suppresses regrowth, which slows the cycle considerably.
