Why Roof Cleaning Matters
Dark streaks on a roof are often more than ordinary dirt. In many cases, they’re caused by Gloeocapsa magma, a type of algae that thrives in
warm, humid conditions like those commonly found in Lexington, Kentucky. As it spreads across roofing materials, it creates the black
discoloration frequently seen on asphalt shingles and may also encourage moss, lichen, and mildew to develop in shaded or moisture-prone
areas.
Professional roof cleaning removes this buildup safely. Most residential roofs are cleaned with a soft washing process that targets algae, moss,
lichen, and other surface contaminants while helping preserve the condition and appearance of the roof. Routine roof cleaning keeps stains from becoming more noticeable over time and helps maintain a cleaner-looking exterior.
Roof Materials We Clean
Asphalt shingle is the roof we work on most often in Lexington, but it isn’t the only one. We adjust the cleaning solution and rinse technique based
on what’s actually on the roof, not a one-size-fits-all approach.
Asphalt Shingle — The most common roofing material in Lexington, and the most vulnerable to Gloeocapsa magma staining. Soft washing removes
it without disturbing the protective granules.
Tile — Durable but still prone to algae and moss in shaded areas. We use a lower-pressure approach to avoid cracking or dislodging individual tiles.
Metal — Resists algae better than shingle roofs, but still collects dirt, pollen, and streaking over time. We clean it without the abrasive contact that
can scratch a painted or coated finish.
Cedar Shake — One of the more delicate roofing materials. Cedar needs a gentler solution and rinse to remove organic growth without stripping the wood’s natural oils or accelerating wear.
Soft Washing vs. High-Pressure Roof Cleaning
Unlike concrete or other hard exterior surfaces, most residential roofs should not be cleaned with high-pressure water. Asphalt shingles are
designed with protective mineral granules that help shield the roof from weather and sunlight. Excessive pressure can dislodge these granules,
shorten the roof’s service life, and leave the surface more vulnerable to future wear. Many roofing manufacturers also recommend avoiding high-pressure washing because improper cleaning methods may affect warranty coverage if damage occurs.
Soft washing is the method commonly recommended for roof cleaning. It uses a specialized cleaning solution to break down algae, moss, and
other organic growth before the roof is rinsed with low-pressure water. This approach cleans the surface gently, which is exactly what asphalt
shingles and most other roofing materials need.
High Pressure Alone
Can dislodge protective granules, shorten shingle life, and put warranty coverage at risk.
Soft Washing (Our Method)
A specialized solution breaks down algae and moss, then a low-pressure rinse clears it away safely.
Will Soft Washing Void My Shingle Warranty?
No. Soft washing is the method most roofing manufacturers actually recommend for cleaning asphalt shingles. It’s high-pressure washing that tends
to void warranties, since the force can strip away the protective granules the warranty depends on. If you’re ever unsure what your specific manufacturer allows, it’s worth checking your warranty documentation, but soft washing is built around protecting the roof, not risking it.
Our Roof Cleaning Process
Roof Inspection
We inspect the roof to identify the roofing material, algae or moss growth, and any areas that need extra attention.
Landscape Protection & Cleaning Solution
We pre-soak plants and landscaping around the home, then apply a professional roof cleaning solution and let it dwell for 15–20 minutes.
Low-Pressure Soft Wash
We rinse the roof using a soft washing system that typically runs under 100 PSI, removing the loosened contaminants.
Final Inspection & Quality Check
Once the roof has been cleaned, we complete a final walkthrough to check for consistent results, inspect any remaining problem areas, and take care of any spots that need a second pass before the project is finished.
Roof Cleaning Pricing
$600–$1,200 for most residential roofs
The cost depends on several factors, including the size and pitch of the roof, the roofing material, accessibility, and the amount of algae, moss, or organic buildup that needs to be removed. Larger or more complex roofs may require a customized estimate.
