Roof Cleaning in Austin, TX
Those black streaks are living algae feeding on your shingles. We soft wash roofs at low pressure with biodegradable solution — no blasting, no granule loss, no voided warranty.
Gloeocapsa magma is the algae responsible for the dark streaking on Central Texas roofs. Pressure washing a roof strips protective granules and shortens its life. We use the low-pressure soft wash method recommended by shingle manufacturers: the solution does the work, the roof gets rinsed, and the growth is killed at the root instead of just being knocked loose.
Tile, metal, and composite roofs each get a different approach and dwell time. Landscaping and plantings are pre-wet and rinsed throughout, and every solution we use is 100% biodegradable.
Roof cleaning is the single biggest curb-appeal change we make to a property, which is why it is our most-requested service alongside window cleaning — especially for homeowners preparing to list.

Roof Cleaning FAQs
Will pressure damage my shingles?
We never pressure wash a roof. Soft washing uses low pressure and a cleaning solution, which is the method shingle manufacturers recommend.
How long do results last?
Because the algae is killed rather than blasted off, most Central Texas roofs stay clear for three to five years.
Is the solution safe for plants and pets?
Yes. We use 100% biodegradable solutions and pre-wet and rinse all landscaping. Pets should stay indoors during the service.

Best window cleaning we have had in Austin, hands down. They showed up exactly on time, covered the floors, and the glass looks like it isn't even there. Already booked them quarterly.

Our roof had black streaks across the whole south side. Casa Washa soft washed it and it looks like a brand new roof. Neighbors have asked who we used three separate times.

I use them on every listing now. Windows, driveway, and a full interior clean before photo day. The listing photos are noticeably better and the homes show incredibly well.
