What those streaks really are
In Southwest Florida, black or green streaks on tile and shingle are most often organic growth that thrives in humidity and shade. It spreads gradually and holds moisture against the roof surface.
Why low pressure matters
Roofing materials aren't designed to be blasted. Soft washing treats the growth with a suitable solution, then rinses gently — cleaning without forcing water where it shouldn't go.
Preparing for roof cleaning
Close windows, move cars and patio items, and tell your provider about sensitive plants. Pre-wetting and rinsing landscaping is standard practice for a careful crew.
Setting expectations
Most biological staining responds well. Some older or mineral stains may lighten rather than vanish, and growth eventually returns depending on shade and trees. An honest provider will tell you this upfront.
