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.
Logan County gets the full range — freeze-thaw cycling through winter, severe convective storms with hail and straight-line wind in spring and summer, and enough temperature swing between them to work every joint on the roof loose. Freeze-thaw is the quiet one: water finds a hairline gap in flashing, freezes overnight, expands, and opens it slightly wider, repeating through a Logan County winter until a joint that was watertight in October is leaking by March. Spring brings the loud damage, and derechos have put straight-line wind through this region at speeds that take ridge caps and whole shingle courses. Housing stock here is older than average, which means a lot of roofs where the flashing has already been through several decades of that cycle.
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.
