Will roof cleaning damage my shingles?

No. We use a low-pressure soft washing method that safely cleans asphalt shingle roofs without removing protective granules. High-pressure washing can damage shingles and may void manufacturer warranties, which is why we never use it on asphalt roofs.

How long does roof algae take to come back after cleaning?

The time varies depending on humidity, shade, tree coverage, and weather conditions. Most roofs stay cleaner for a considerable period after professional soft washing, although Jacksonville's warm, humid climate can encourage algae to return over time.

Can you clean a tile roof?

Yes. We clean tile roofs using a soft washing process designed for the roofing material. This helps remove algae, mold, mildew, and other organic growth while reducing the risk of cracking tiles or forcing water beneath them.

Is roof cleaning covered by my roofing warranty concerns?

Many roofing manufacturers advise against high-pressure washing because it can damage roofing materials and affect warranty coverage. Our soft washing method is designed to clean roofs safely without the risks associated with high-pressure cleaning.

What’s the difference between roof cleaning and gutter cleaning?

Roof cleaning removes algae, mold, mildew, lichen, and stains from the roof's surface using a soft washing process. Gutter cleaning focuses on removing leaves, twigs, and debris from gutters and downspouts to help maintain proper water drainage.

Roof Cleaning in Jacksonville, FL (Soft Wash Only)

Those black streaks running down your roofline aren’t dirt or mildew — they’re a specific type of algae (commonly Gloeocapsa magma) that feeds on the limestone filler in asphalt shingles and thrives in warm, humid climates like Jacksonville’s. It spreads from shaded, north-facing areas outward, and it will keep spreading until it’s treated properly.

Why We Never Use High Pressure on a Roof

This is the most important thing to know before hiring anyone for roof cleaning: high-pressure washing on asphalt shingles strips the protective granules that shield the shingle from UV damage, which shortens the life of your roof and can void your roofing manufacturer’s warranty outright. Most roofing manufacturers explicitly exclude pressure washing damage from warranty coverage. Tile roofs face a different but related risk — high pressure can crack tiles or force water underneath them.

Soft wash roof cleaning uses a low-pressure application of a cleaning solution designed to kill the algae, moss, and lichen at the root, then a gentle rinse. No granule loss, no cracked tiles, no warranty risk.

Why Jacksonville Roofs Are Especially Prone to This

Jacksonville’s combination of high humidity (averaging around 75%) and heavy oak canopy in neighborhoods like Riverside, Avondale, San Marco, and Mandarin creates ideal conditions for algae and moss to establish on shaded roof sections.
Homes near the coast in Jacksonville Beach see it too, just with the added factor of salt air affecting metal fixtures and flashing over time.

What’s Included in Roof Cleaning	Our Process
Roof Inspection	We inspect your roof’s material and condition before starting. Asphalt shingles, tile, and metal roofs each require a different cleaning approach.
Soft Wash Treatment	A professional soft wash cleaning solution is applied to eliminate algae, mold, mildew, lichen, and other organic growth at the source.
Proper Dwell Time	We allow the cleaning solution to dwell long enough to break down stains and contaminants before rinsing.
Low-Pressure Rinse	Your roof is gently rinsed using a low-pressure soft wash system—never high-pressure washing that can damage shingles or roofing materials.
Gutter Check	As part of the service, we inspect gutters for debris and buildup that commonly contribute to roof staining and drainage issues.

Not when done correctly with soft wash technique. High-pressure roof cleaning is what causes shingle and warranty damage — we don’t do that.

Properly soft-washed roofs (killing the algae at the root, not just knocking off the visible black streaking) typically stay clean for one to two years, though shaded, humid roof sections may need attention sooner.

Yes, with a method matched to tile — high pressure is avoided here as well, since it can crack tiles or force water underneath.

Soft washing is the industry-recommended method precisely because it avoids the pressure-related damage that voids most roofing warranties — but always confirm your specific manufacturer’s terms if you’re unsure.
