How does Vista's climate affect this service?
Vista runs a mix of inland-valley residential, ag-zone properties feeding into the Buena Vista Creek corridor, and significant commercial inventory along South Santa Fe Avenue and the Highway 78 strip. Red-clay dust from the surrounding rural sections settles into concrete pores and adds to the standard inland-valley dust load.. Inland roof cleaning runs lighter on algae, heavier on bird nest debris, palm fronds, and dust caked into shingle granules.
Will soft washing hurt my shingles?
No, soft washing is the method the Asphalt Roofing Manufacturers Association (ARMA) recommends. High-pressure washing of asphalt shingles is what damages them. Correctly diluted SH with a surfactant, applied at low pressure, kills the algae without touching the granules.
Why does only one side of my roof have streaks?
Gloeocapsa loves shade and moisture. The north-facing slope (and the west-facing in some San Diego microclimates) stays damper longer, so that's where the colony takes hold. It spreads slowly from there. That's also why coastal homes get streaks faster, marine layer fog feeds it.
