Remove Black Streaks From Your Roof

Professional roof cleaning services using soft wash techniques in Prattville, Alabama

Your roof in Prattville probably has dark streaks running down the shingles, especially on the side that faces away from the sun. Those streaks are not dirt. They are algae feeding on the limestone filler in asphalt shingles, and they hold moisture against the surface, which accelerates wear and shortens the lifespan of your roof. Roof cleaning removes the algae and restores the appearance of the shingles without using high pressure that could loosen granules.

Waterboy Cleaning Services LLC uses soft wash techniques to safely clean roofs throughout Prattville and surrounding areas. The process applies a low-pressure cleaning solution that kills algae, moss, and mildew at the root, then rinses the surface gently to avoid damage. This method is suitable for asphalt shingle roofs and other common residential roofing types found in central Alabama, and it helps extend the life of your roof by removing organic growth that traps moisture.

If your roof has black streaks or green patches forming near the edges, contact us to schedule a roof cleaning in Prattville.

Why algae grows on roofs in Alabama

Roof cleaning in Prattville starts with an inspection to identify the type of growth and the condition of the shingles. The crew then applies a biodegradable cleaning solution using a low-pressure pump system. The solution clings to the shingles and works for several minutes to break down algae and moss. After the dwell time, the roof is rinsed gently from top to bottom, and the dead organic material washes into the gutters or off the edges.

Once the roof dries, the black streaks are gone and the shingles return to their original color. The surface also sheds water more effectively because the algae layer that was trapping moisture has been removed. This can help prevent granule loss and early shingle deterioration caused by prolonged dampness.

Roof cleaning is safe for asphalt shingles, architectural shingles, and most composite roofing materials. It is not recommended for wood shake, tile, or metal roofs without prior assessment. The service is licensed and insured for roof-level work, and the crew takes precautions to protect gutters, landscaping, and nearby surfaces. Scheduling depends on weather, and most residential roofs are cleaned in a few hours.

Here is what homeowners usually ask

People in Prattville often want to know if roof cleaning is safe, how long the results last, and whether it can damage shingles. Below are answers to the most common concerns about roof cleaning services.

What causes black streaks on asphalt shingles?
The streaks are caused by algae called Gloeocapsa magma, which feeds on the limestone in shingles. It thrives in humid climates like Alabama and spreads across shaded roof sections.
Will roof cleaning damage my shingles?
No. Soft washing uses low pressure and cleaning solutions to kill algae without dislodging granules or lifting shingle edges. It is much safer than high-pressure washing.
How long will my roof stay clean?
Most roofs in Prattville stay clean for two to four years after treatment, depending on shade, tree proximity, and humidity. The cleaning solution kills spores, which delays regrowth.
Can roof cleaning extend the life of my roof?
Yes. Algae and moss trap moisture against the shingles, which can cause granule loss and premature wear. Removing that growth helps the roof dry faster and last longer.
What should I do before the service?
Move vehicles away from the driveway and close any skylights or attic vents. The crew will protect landscaping and gutters, but you should let them know if there are any concerns.
