Tile Roof Cleaning Project in Parkland, Florida
Nevins Services completed this concrete tile roof cleaning project in Parkland Golf & Country Club in Parkland, Florida. The roof had developed extensive dark organic staining and microbial growth that had significantly changed the appearance of the original multicolor concrete tile.
The dark roof streaking visible before cleaning is commonly associated with Gloeocapsa magma, a photosynthetic cyanobacterium frequently found on roofing surfaces in warm, humid climates such as South Florida. Other organic growth and environmental buildup can contribute to the discoloration as well.
For this property, we used the same low-pressure process we use for our professional roof cleaning in Parkland, FL, allowing the cleaning solution to do the work rather than relying on aggressive pressure.

Gloeocapsa Magma and Organic Growth on the Concrete Tile Roof
South Florida’s warm temperatures, humidity, and frequent rainfall create favorable conditions for black algae and other organic growth to develop on residential roofs. Over time, that growth can cause concrete tile roofing to appear significantly darker than its original color.
That was especially noticeable on this Parkland home. From the aerial view, large sections of the roof appeared dark brown and almost black. Beneath that buildup, however, the roof consisted of much lighter red, tan, and natural-colored concrete tiles.
Why the Roof Looked So Dark
The discoloration was primarily concentrated across the exposed tile surfaces, valleys, and areas where moisture and organic growth had accumulated over time. The difference between the contaminated surface and the original tile became much more apparent once the roof was cleaned.

Our Low-Pressure Soft Wash Roof Cleaning Process
Rather than attempting to remove years of roof staining with high-pressure water, the concrete tile was treated using a professional soft wash solution applied at low pressure.
Soft washing allows the cleaning solution to address the organic and microbial growth responsible for much of the discoloration while minimizing unnecessary mechanical pressure on the roof surface. This is especially important on large concrete tile roofing systems with numerous ridges, valleys, penetrations, flashing points, and other components.
Our soft wash roof cleaning process is designed to clean the roofing surface thoroughly while using a method appropriate for the material being treated.
Cleaning Concrete Roof Tile Without High Pressure
Concrete roof tile is durable, but that does not mean aggressive pressure washing is the best method for cleaning it.
Using excessive pressure can unnecessarily place mechanical force on the surface of the tile and around vulnerable areas of the roofing system. Our approach relies primarily on proper solution application and dwell time to loosen and treat the organic growth rather than trying to blast the staining from the roof.
This allows us to restore the appearance of the tile while taking a more controlled approach to the cleaning process.
Landscape and Property Protection
Roof cleaning involves more than treating the roofing surface itself. Protecting the areas surrounding the home is an important part of the process.
Landscaping and other sensitive areas around the property are managed throughout the cleaning and thoroughly rinsed with fresh water while the roof is being treated. Extra attention is given to ornamental landscaping, planting beds, hardscape areas, and other surfaces surrounding the home.
Before and After Tile Roof Cleaning Results
The difference after cleaning was substantial.
Before treatment, years of dark organic staining had covered much of the roof and made the concrete tile appear considerably darker than its original color. Once the buildup was treated and removed, the red, tan, and lighter color variations of the tile became visible again.
The aerial photography makes the transformation particularly clear. What initially appeared to be an extremely dark roofing system was actually a much lighter multicolor concrete tile roof beneath the accumulated organic growth.

Restoring the Original Appearance of the Concrete Tile
One of the most noticeable aspects of this project was how much of the roof’s original color had been hidden by the buildup.
The finished roof shows the natural variations throughout the concrete tile again instead of the dark, uneven appearance visible before cleaning. Because the change can be viewed from directly above, the before-and-after photographs provide a particularly clear example of what professional roof cleaning can accomplish on a heavily stained tile roof.
The objective was not to alter the roofing material or make it look artificially new. It was to remove the accumulated organic staining and reveal the appearance of the existing tile underneath.
Roof Cleaning in Parkland Golf & Country Club
Parkland Golf & Country Club includes many larger homes with substantial concrete tile roofing systems, extensive landscaping, pools, paver driveways, and other exterior surfaces that require careful cleaning methods.
This project is a good example of why the cleaning method matters. The roof required enough treatment to address significant organic buildup while still using an approach appropriate for concrete tile and the surrounding property.
Nevins Services provides roof cleaning throughout Parkland, including Parkland Golf & Country Club and surrounding communities.

Concrete Tile Roof Cleaning in Parkland
Nevins Services cleans concrete tile, barrel tile, flat tile, asphalt shingle, and other residential roofing systems throughout Parkland and surrounding Broward County communities. The cleaning method is selected based on the roofing material and condition of the property rather than using the same approach on every roof.
Does Your Tile Roof Look Like This?
Dark streaking, discoloration, and organic buildup can gradually change the appearance of a tile roof enough that homeowners may not realize how much of the original color has been hidden.
If your roof in Parkland or another Broward County community is beginning to resemble the before photos from this project, we can evaluate the roof and recommend an appropriate cleaning approach based on the roofing material, condition, and level of buildup.
