YOUR ROOF IS TRYING TO TELL YOU SOMETHING
What Are Those Black Streaks on Your Roof?
Founded by a former roofer, Hydro Wash 360 knows roofs from the inside out. If you have dark streaks running down your roof, you are not alone. Most homeowners in Jacksonville deal with this at some point. Those streaks are not just dirt or stains. They are caused by a bacteria called gloeocapsa magma that feeds on the limestone in your shingles.
Jacksonville’s warm, humid climate creates the perfect environment for this bacteria to spread fast. Once it takes hold, it does more than make your roof look bad. Over time, it breaks down your shingles from the surface level and shortens the life of your entire roof. According to the Asphalt Roofing Manufacturers Association (ARMA), the only recommended way to remove this growth safely is with a low pressure cleaning method. High pressure washing strips away protective granules and can void your roof’s warranty.
The good news is that professional roof cleaning in Jacksonville FL stops the damage before it gets worse. A soft wash treatment removes the bacteria completely and helps your roof last years longer.




Why We Never Pressure Wash a Roof
Your roof is one of the most important parts of your home. Unfortunately, it is also one of the most easily damaged by the wrong cleaning method. At Hydro Wash 360, we only use soft washing because it is the safest and most effective way to clean your roof.
Pressure Washing
(Why It’s Dangerous)
Many companies in Jacksonville still use high pressure to clean roofs. However, this is one of the worst things you can do to your shingles. High pressure strips away the protective granules that shield your roof from UV rays and rain. In addition, it can crack tiles, bend metal panels, and force water underneath your shingles. As a result, you end up with leaks, void warranties, and a roof that ages faster. Simply put, pressure washing a roof causes more harm than good.
Soft Washing Roof Cleaning
(The Right Way)
Soft washing takes a completely different approach. Instead of blasting your roof with force, our team applies a specialized low pressure cleaning solution that breaks down algae, mold, and bacteria at the root. Consequently, the growth is killed and safely rinsed away without touching the surface integrity of your shingles. In other words, it cleans your roof thoroughly while keeping your warranty fully intact.

What Types of Roofs Can Be Soft Washed?
Every roof material reacts differently to cleaning. That is exactly why our team adjusts the solution and technique based on your specific roof type. Here is how we handle each one.
Asphalt Shingle Roof Cleaning
Metal Roof Cleaning
Tile Roof Cleaning
Flat Roof Cleaning
Flat roofs trap standing water and moisture more than any other style. Consequently, mold and algae growth can spread quickly across the entire surface. Our soft wash treatment clears the buildup and helps prevent future growth from taking hold.

Roof Cleaning Warranty
We guarantee treated asphalt shingle roof areas against the return of black algae staining (Gloeocapsa magma) for up to two (2) years from the date of service.
If black algae staining returns under normal environmental conditions within the warranty period, we will retreat the affected areas at no charge.
This warranty does not cover:
- Damage from storms, hurricanes, or natural disasters
- Excessive shade or heavy tree debris accumulation
- Rust stains, oxidation, or structural defects
- Physical damage to shingles or roofing materials
When applied properly with correct dwell time and rinsing procedures, soft washing delivers long-term results. We stand behind it.

How Does Soft Wash Roof Cleaning Work?
1. Schedule a Free Roof Inspection
It starts with a quick call or form. From there, we set up a time to inspect your roof and assess the level of algae, mold, or staining. In most cases, your quote is ready the same day so you can make a decision without the back and forth.
2. Protect Your Landscaping and Property
Before any solution touches your roof, our team takes time to prep the area below. Specifically, plants and flower beds along the drip line get soaked and covered. In addition, downspouts near concrete or grass are bagged to contain any runoff. Above all, your landscaping stays safe throughout the entire process.
3. Apply the Soft Wash Solution
Next, our team applies a specialized low pressure cleaning solution across your entire roof. This solution targets and kills algae, mold, mildew, and gloeocapsa magma at the root. As a result, the growth breaks down without any scrubbing, scraping, or high pressure contact.
4. Low Pressure Rinse
After the solution has done its job, a gentle low pressure rinse removes the dead bacteria and debris from your roof. Unlike other companies, we do not leave the solution sitting and wait for rain. Instead, we take the extra time to rinse your roof so you see results before we leave.
5. Post-Clean Property Check
Once the rinse is complete, our team does a full walkthrough of your roof, gutters, and landscaping. If anything needs attention, it gets handled on the spot. Ultimately, the job is not finished until your roof looks brand new and your property is exactly how we found it.
Your roof protects you.
