Roof Cleaning & Soft Washing
Remove black streaks, algae, moss, and lichen with a gentle soft wash — never high-pressure washing that can strip granules and shorten shingle life.
Why Houston Roofs Get Those Black Streaks
Those black streaks on Houston-area roofs are usually a bacteria called Gloeocapsa magma that thrives in our humidity and feeds on the limestone filler in asphalt shingles. Left untreated, it spreads, holds moisture against the roof deck, and can shorten the life of your shingles. High-pressure washing makes it worse by stripping protective granules — which is exactly why we never use it on a roof.

How It Works
Roof Inspection
We check the roofline for algae, moss, lichen, and problem drainage areas before starting.
Soft Wash Application
A roof-safe cleaning solution is applied at low pressure to break down growth at the root.
Dwell & Treat
The solution dwells long enough to kill algae and moss spores, preventing quick regrowth.
Low-Pressure Rinse
A gentle rinse clears away residue, leaving your roof clean without a single stripped granule.
