Roof Cleaning in San Marcos, what we see out here.
San Elijo Hills and Lake San Marcos share the same tile-roof story, the north pitch stays shaded, algae takes hold, and streaks appear within 3 years of a new roof.
Hot sun bakes on north-side algae streaks , which is exactly the environment our roof cleaning process is built for.

San Marcos FAQs
Will soft-washing hurt my roof or plants?+
No. The mix is diluted, applied at garden-hose pressure, and every plant is pre-soaked and re-rinsed. We've used this method on 1,000+ roofs with zero warranty issues.
How long before the streaks disappear?+
The organisms die on contact. Visual clearing takes 30–90 days as rain and UV break down the dead biomass. On dark tiles you'll see it faster.
How often do I need this done?+
Coastal homes: every 3–5 years. Inland (Vista, Escondido, Temecula): every 5–7 years. Our 5-year no-regrowth touch-up covers you either way.
Do you clean gutters at the same time?+
Yes, add $95 for a full gutter clean-out (bag & haul included).
