Pressure Washing
Soft Wash Roof Cleaning
Soft-wash roof cleaning removes the black streaks and green growth caused by Gloeocapsa magma algae, a common problem on Florida roofs. Rather than blasting shingles or tile with high pressure — which can strip protective granules and void a manufacturer's warranty — we use a low-pressure application that lifts algae safely.
What's Included
- Algae and black-streak removal from shingle and tile roofs
- Low-pressure, warranty-safe application
- Moss and mildew treatment near the roofline
- Landscaping protection during the wash
What Does Roof Cleaning Cost?

Our Process
Property preparation
Surrounding plants and surfaces are thoroughly wetted down for protection before we start.
Soft-wash application
A low-pressure system applies cleaning solution evenly across the roof.
Algae treatment and rinse
The solution breaks down algae and spores, followed by a careful rinse that leaves the surface clean without stripping granules.

Frequently Asked Questions
Is soft-wash roof cleaning safe for my roofing material?
Yes — the solution is biodegradable and formulated to be safe for shingle and tile roofing, as well as surrounding landscaping.
How long do the results last?
Most soft-washed roofs stay clean for roughly a year and a half to three years, depending on tree cover and weather exposure.
Why not just pressure wash the roof?
Standard high-pressure washing can strip protective granules from shingles and void the manufacturer's warranty — soft washing avoids that risk entirely.
