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.
Treasure Island sits on a stretch of coast where hurricane exposure is the defining fact of roofing. Sustained wind drives rain horizontally under shingle courses that would shed any vertical downpour, and it works tabs loose over hours rather than tearing them off — so the roof reads as undamaged right up until the next storm. Between seasons, the heat and humidity across Pinellas County harden every rubber and sealant component and keep anything that gets wet from drying. The insurance picture matters as much as the weather here: Florida's market has reshaped how roof claims are handled, deductibles for named storms are calculated differently from ordinary ones, and documentation taken before any work starts is what decides how a claim goes.
Treasure Island has a population of about 6,584, and the housing stock here sets the pattern for what fails first on a roof.
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.
