Roof washing in San Antonio — black streaks gone, shingles undamaged

Those black streaks on your roof are algae eating your shingle granules. Soft washing actually fixes it — pressure washing makes it worse.

How we do it

A pressure washer on shingles strips granules and shortens roof life by years. Soft washing uses a low-pressure cleaning solution that kills the algae at its root — the streaks come off in subsequent rains, and they stop coming back for 4–6 years.

Why customers pick us

  • Soft wash, not pressure wash. Shingles intact, granules intact, roof life extended.
  • Streaks gone for years. We kill the algae, not just rinse the surface.
  • Insurance-friendly process. Documentation provided on request.

Frequently asked questions

Will the streaks come back?
Not for 4–6 years on most San Antonio homes — because we kill the algae, not just rinse the surface.
Is it safe for my plants?
Yes — we pre-rinse and post-rinse landscaping.
Do you walk on my roof?
Only when necessary and only when safe. We do most work from ladders and ground-based reach systems.
Can you treat just one section?
Yes, but the whole-roof rate is usually better value.
