The concern with metal isn’t granule loss or cracking: it’s damaging the protective coating or finish that keeps the metal from corroding. Why is coating the main concern on a metal roof?

Pavers generally need attention more often than poured concrete, mainly because the joints between individual pavers give algae more places to take hold than a single continuous concrete surface does. Quick Facts Pavers: more surface texture and joints, generally faster algae establishment Poured concrete: fewer places for algae to take hold, generally slower buildup Shared…

Both tile and asphalt shingle roofs should be soft washed rather than pressure washed, but tile can tolerate more careful pressure than shingle, while shingle roofs are more easily damaged by high pressure specifically because of their granule layer. Quick Facts Asphalt shingle: soft wash only, high pressure strips protective granules Clay or…

Most Florida homeowners insurance policies treat roof algae staining itself as a cosmetic issue, which is generally excluded from coverage, but the functional damage algae can cause over time, like granule loss and moisture intrusion, is sometimes treated differently. Coverage varies significantly by carrier and policy, so this is general information, not a guarantee of…

The same humidity, warmth, and frequent rain that caused the original buildup are constantly present, so surfaces are exposed to new algae spores continuously rather than just once. Why doesn’t a cleaning just solve the problem permanently? Florida’s humidity and…
