Softwash Roof Cleaning

THE SCIENCE & TECHNOLOGY OF SOFTWASH ROOF CLEANING

THE TRUTH BEHIND ROOF STAINS, WHAT THEY ARE, WHY THEY ARE THERE, AND HOW THEY GOT THERE.
Before and After
The Evolution of Roof Cleaning

Roof cleaning as an industry emerged in the late 1980s and early 1990s. In its early stages, different methods were tried to clean roofs that were often covered with various organisms. At first, it was more of a "garage art," primarily popular in the Southern United States, especially in Florida, with the initial focus on removing unsightly black streaks.

​

However, it was later discovered that these streaks were caused by organic growth, which is best treated with algaecides—similar to treating fungal infections in gardens. This discovery transformed the industry, revolutionizing how roof cleaning is performed and shifting the focus from mere appearance to effective, long-term solutions.

What Causes Black Streaks on Roofs?

 

The primary cause of unsightly black streaks on roofs is a bacteria called Gloeocapsa Magma. This bacteria thrives in warm, moist environments and often coexists with other microorganisms like mold, fungi, algae, mildew, lichen, and moss. Many roofing materials, particularly shingles that contain limestone, provide a perfect food source for these organisms. Over time, the bacteria and other microorganisms feed on the shingles, leading to roof staining and deterioration.

MORE THAN JUST A WASH

Soft washing goes beyond surface cleaning. The specially formulated products used in SoftWash systems not only remove stains but also sanitize, penetrate, and eliminate the root cause of the problem. One of the main culprits behind roof staining—particularly the black streaks—is a bacteria called Gloeocapsa Magma. Unlike traditional methods, soft washing targets and kills this bacteria from the root, ensuring a deep, long-lasting clean.

Shingle Deterioration: The Hidden Danger on Your Roof
​
Just like plants, fungi, and algae growing on your roof have root systems that can cause significant damage. These microorganisms penetrate the shingles, leading to issues like uplifting, spreading, and eventual decomposition. In the same way a tree’s roots can overtake structures—like the ancient Asian temple shown in the photo—the filament root systems of fungi and algae dig into your roof, slowly compromising its integrity.
As these roots open tiny cracks in shingles, tiles, or other roofing materials, they cause the front edges of shingles to flare and roll. Since the back of the shingle remains attached, the front widens and curls, making your roof more vulnerable to further damage.
In addition to this biological deterioration, natural forces such as water erosion can also contribute to roof damage. Just as water erosion formed the Grand Canyon, the impact of running water on your roof can accelerate the breakdown of materials, further shortening your roof's lifespan.

The Four Forces Behind Shingle Deterioration

 

If you examine a picture of swollen, poorly maintained shingles, you can clearly see the damage being done. Four primary forces contribute to the breakdown of shingles due to algae and fungi:

​

  1. Decomposition from Filament Root Systems
    Algae and fungi develop filament root systems that penetrate and crack shingles, causing them to curl and swell. Over time, this weakens the roof’s structure.

  2. ​Limestone Consumption
    Algae and fungi thrive on the limestone fillers used in shingles. Limestone, rich in phosphates, is an ideal nutrient source for these organisms, which accelerates roof degradation.

  3. Acidic Waste Production
    As algae and fungi metabolize the limestone, they produce acidic waste that further damages the shingles by breaking down their structure and integrity.

  4. Excess Heat Absorption
    The dark streaks caused by algae increase the amount of heat absorbed by the shingles. This excess heat dries out the petroleum in the shingles, accelerating aging and deterioration.
