Safe Roof Cleaning & Soft Washing
Remove black streaks, moss, lichen, and algae from your roof without voiding your warranty or damaging shingles.
About Our Roof Cleaning Service
Those dark streaks on your roof aren't just unsightly — they're a living organism called Gloeocapsa Magma, a type of algae that feeds on the limestone filler in asphalt shingles. Left untreated, it can significantly shorten your roof's lifespan. BK Pressure Washing uses ARMA-recommended soft wash techniques to safely eliminate roof algae, moss, and lichen without damaging your shingles or voiding your warranty.
Key Benefits
ARMA-Recommended Method
We follow the Asphalt Roofing Manufacturers Association guidelines — no high pressure that damages shingles.
Extends Roof Life
Removing algae and moss prevents premature shingle degradation and can add years to your roof.
Improves Energy Efficiency
Dark algae stains absorb heat — a clean roof reflects more sunlight and reduces cooling costs.
Warranty Safe
Our soft wash method won't void your roofing manufacturer's warranty.
Our Process
A proven, step-by-step approach that delivers consistent, professional results every time.
Roof Assessment
We inspect your roof type, pitch, and condition to determine the safest cleaning approach.
Solution Application
We apply our biodegradable soft wash solution that kills algae, moss, and lichen at the root.
Dwell Time
The solution is allowed to dwell and fully penetrate organic growth before rinsing.
Low-Pressure Rinse
A gentle rinse removes all residue without disturbing granules or shingle integrity.
Frequently Asked Questions
Is pressure washing safe for my roof?
High-pressure washing is NOT safe for asphalt shingles — it strips granules and voids warranties. We use soft wash (low pressure + cleaning solution), which is the ARMA-recommended method.
How long does roof cleaning last?
Results typically last 2–5 years depending on your environment. We can apply a preventative treatment to extend the time between cleanings.
Will roof cleaning damage my gutters or landscaping?
We pre-wet and protect all landscaping before applying cleaning solutions, and we rinse thoroughly afterward. Our solutions are biodegradable and safe for plants when properly diluted.
