Softwash Roof Cleaning in Monroe, LA: What It Is and Why It Matters
By WeatherPro Roofing | Roof Cleaning & Restoration Experts in Northeast Louisiana
Have you noticed black streaks on your roof? It might look like simple dirt or water stains, but what you’re actually seeing is an organic infestation — and it’s slowly damaging your roof.
At WeatherPro Roofing, we offer professional softwash roof cleaning services in Monroe, West Monroe, and surrounding areas, using safe, science-backed methods to eliminate stains and restore your roof’s health and appearance.
Let’s break down the truth behind roof stains, what causes them, and how softwashing can save your roof (and your wallet).
What Causes Black Roof Streaks?
The main culprit is Gloeocapsa Magma, a type of airborne bacteria that thrives in Louisiana’s warm, humid climate. Once it lands on your shingles, it feeds on the limestone filler in asphalt shingles, spreads across the surface, and leaves behind black streaks and patches.
Other roof-damaging organisms often appear alongside it, including:
- Algae
- Mold
- Mildew
- Lichen
- Moss
- Fungi
Together, they create a microbial ecosystem that can eat away at your shingles, weaken their structure, and reduce the overall lifespan of your roof.
What Is Softwash Roof Cleaning?
Softwashing is a low-pressure roof cleaning method that uses specially formulated solutions to kill algae and bacteria at the root — not just rinse away surface stains.
Unlike power washing (which can damage shingles), softwashing is:
- ✅ Safe for shingles, tile, and metal roofs
- ✅ Effective at sanitizing and removing algae, moss, and mildew
- ✅ Eco-friendly, using biodegradable algaecides and surfactants
- ✅ Long-lasting, preventing regrowth for up to 3–5 years
At WeatherPro Roofing, we use commercial-grade softwash systems that clean, sanitize, and restore your roof without damaging it.
Why Roof Stains Are More Than Just Ugly
Those black streaks aren’t just hurting your curb appeal — they’re hurting your roof’s integrity.
Here’s how microorganisms like algae and fungi damage your roof:
- 1. Shingle Decomposition
Algae and fungi form filament-like root systems that dig into the shingles, breaking them down over time and creating micro-cracks. - 2. Shingle Separation & Curling
As algae spreads, it causes the front ends of shingles to lift and roll, making them more vulnerable to wind and rain damage. - 3. Acidic Waste
The organisms feed on limestone fillers and release acidic waste, which corrodes shingles and accelerates aging. - 4. Increased Heat Absorption
Dark streaks absorb more sunlight, causing shingles to overheat and dry out, leading to faster petroleum degradation and premature failure.
Signs Your Roof Needs Softwashing
- Streaks or black patches visible from the ground
- Moss or algae growing on shingles
- Curling or cracked shingle edges
- A spike in attic or indoor temperatures
- Increased energy bills (due to lost reflectivity)
Don’t wait until your roof is failing. A professional softwash can restore your roof’s appearance and extend its life by years.
Softwash vs. Pressure Washing: What’s the Difference?
| Feature | Softwash | Pressure Washing |
|---|---|---|
| Pressure Level | Low | High |
| Uses Chemicals? | Yes (algaecides) | Sometimes |
| Shingle Safe? | ✅ Yes | ❌ Risk of damage |
| Long-Lasting Results | 3–5 years | Weeks to months |
| Kills Root Cause? | ✅ Yes | ❌ No (just rinses) |
Bottom line: If you’re dealing with roof algae, softwashing is the only safe and effective option.
