Why Queensbury Homeowners
Can't Ignore Black Streaks, Moss, and Lichen on Their Roofs
A combination of dense tree canopy, lake moisture, and changing seasons causes destructive biological growth on Queensbury roofs. Algae feeds on shingle limestone to leave black streaks, moss traps water to rot materials, and lichen grips surfaces tightly. Shaded and north-facing roof sections stay damp the longest, making them prime targets. This trapped moisture expands during local freeze-thaw cycles, leading to premature aging, lost curb appeal, and voided manufacturer warranties.
When you reach out to us, our owner answers the phone personally and performs the actual work on every single job. We eliminate subcontractors, franchise layers, and communication gaps, ensuring the team that quotes your project is the exact same crew that shows up to complete it. Every roof is cleaned using a low-pressure soft wash method in strict accordance with ARMA guidelines, which completely protects your shingles, preserves your manufacturer warranty, and keeps your surrounding landscaping perfectly safe.

The Roof Types We Actually
See and Clean in the Queensbury and Adirondack Region
Asphalt Shingles: Queensbury's Most Common Roof
Asphalt shingles are the number one roof type across the Queensbury and Adirondack region, and they make up the majority of our roof cleaning work. No high-pressure equipment ever touches asphalt shingles. This method protects your existing roof manufacturer warranty.
Slate Roofs: The Region's Second Most Popular
Slate is the second most common roof type in the Queensbury and Adirondack area, more prevalent here than in many other parts of New York thanks to the proximity to Vermont quarries and the age of homes in upstate New York.
We don’t apply a one-size-fits-all formula. We adjust our chemistry to match your specific roof type and the severity of growth present.
Metal, Tile, and Clay Roofs
Metal roofs do exist in the Queensbury area, though they’re far less common. Tile and clay roofs are not part of the local building landscape. And that honesty matters more than pretending otherwise.
Roofs We Turn Down
Not every roof is a good candidate for cleaning, and we would rather be upfront about that than take a job that could make things worse. We decline roof cleaning under these conditions:
- Structurally unsafe roofs that cannot support the safe presence of a crew member or ladder.
- Extremely brittle or deteriorated materials where shingles or slate could fracture or dislodge under normal movement.
- Existing storm damage that needs repair before cleaning can safely proceed.
- Active leaks with water already infiltrating the home.
- Granule loss exposing bare substrate, where chemical application could cause further damage.
- Heavy rain on service day, which creates unsafe access conditions and compromises chemical dwell time.
If your roof has any of these issues, we’ll tell you clearly during the estimate and point you in the right direction, whether that’s a repair or a reschedule. We would rather be honest than take a job that could make things worse.
What Makes Queensbury Homeowners Pick ADK Pressure Washing
for Roof Cleaning
Our Owner, Bill Personally Handles Every Job
Bill Lashinsky answers the phone 24/7 and performs the work on every roof cleaning job personally. For a service where improper technique can cost thousands of dollars, knowing that the team who quoted the job is the same team on the roof makes a meaningful difference.
A Dedicated Two-Person Crew, Every Time
We always deploy a two-person crew on roof cleaning jobs. One crew member works elevated, either on the roof or on a ladder. The other stays on the ground, pre-wetting landscaping, containing downspout runoff, managing overspray, and diluting any chemical that reaches the ground in real time.
ARMA-Compliant Soft Wash That Protects Your Warranty
All roofs are cleaned using only the soft wash method, in strict accordance with ARMA (Asphalt Roofing Manufacturers Association) guidelines. High-pressure washing on rooftops voids most manufacturer warranties. Our method does not. For homeowners with newer roofs or those preparing to sell, warranty-safe cleaning is a financial decision, not just a preference.
On-Roof Application for Precision Where It Counts
When conditions allow, our crew works directly from the roof surface rather than defaulting to ground-only application. This allows for more controlled chemical placement in valleys, around dormers, and near ridgelines, areas that ground-up spraying frequently misses or under-treats.
A Free Roof Condition Report Comes with Every Cleaning
During every roof cleaning, the crew conducts a visual assessment and provides a basic synopsis of what was observed, including any damaged flashing, lifted shingles, missing granules, or structural concerns worth noting. Most roofing companies charge for inspections. We include it automatically. We will give you a verbal synopsis of our findings and include any issues in our before and after photos which are uploaded directly to your invoice.
Free Cancellation or Reschedule, No Questions Asked
We work on a one-week scheduling block system. Once you’re placed on the schedule, you receive a text and email confirmation with your date, time, and preparation instructions. If something comes up, cancellations and reschedules are accommodated free of charge. Getting on the schedule should never feel like a gamble. We make it easy to book and equally easy to adjust.
Six Consecutive Years as the Post-Star's Best of the Region
ADK Pressure Washing has been voted Best of the Region by the Post Star, the local newspaper serving the Glens Falls and Queensbury area, for six consecutive years. This is a verifiable, community-recognized endorsement, not a self-reported claim. In a market where homeowners are comparing multiple exterior cleaning companies, a six-year streak of local recognition speaks for itself.

How Your Roof Cleaning Works, From First Call to Final Walkthrough
Remote Estimate Using Satellite Imagery and Property Data
Most estimates are provided remotely using Google Earth satellite imagery, Zillow, Multiple Listing Service (MLS) data, and any photos you send. For larger or more complex roofs where pitch, growth severity, and access can’t be assessed from a screen, an on-site visit is scheduled before a formal quote is issued. Estimates are delivered via email and text message. It’s a convenient way to get started without waiting for an in-person appointment.
Scheduling Confirmation and Your Pre-Service Checklist
Once you accept the estimate, you’ll receive a text and email confirmation with the service date, time, and a preparation checklist. Before the crew arrives, make sure the water spigot is accessible, all windows and doors are closed, patio furniture and planters are moved a safe distance from the home, vulnerable items near the roof’s edge are secured, and pets are kept indoors.
One important note: if you have a recently sealed asphalt driveway, let us know in advance. Sodium hypochlorite can react with fresh asphalt sealant, so we adjust our approach or timing accordingly. That’s the kind of field-tested detail that separates professionals from amateurs. We work on a one-week scheduling block system during peak season. Cancellations and reschedules are always free.
Crew Arrival, Property Walk, and Before Photos
The two-person crew arrives and walks the roof and surrounding property and before photos are taken and uploaded before any cleaning begins. The ground crew pre-wets all surrounding plants, landscaping, and sensitive surfaces. Gutter downspouts are contained to control the direction of chemical runoff during cleaning.
Soft Wash Chemical Application
The elevated crew member applies the soft wash solution, a sodium hypochlorite and surfactant blend, from the best access point available. On-roof application is preferred when safe, providing maximum precision in valleys, around dormers, and along ridgelines. Ladder access is used when pitch or surface condition prevents safe roof walking. Ground-up application is the fallback when neither option is feasible.
Application is slow and deliberate to make sure coverage is even without unnecessary runoff. The ground crew simultaneously manages overspray and dilutes any chemical reaching the ground. Chemical dwell time is allowed before the process wraps. The solution will have a noticeable pool-chlorine smell during application. This is normal. Keep windows and doors closed while the crew is working. The odor fades as the solution dries.
Walkthrough, Condition Report, and After Photos
After photos are taken and uploaded directly to your invoice. If you’re home, the crew delivers a verbal roof condition report covering any observed damage, concerns, or areas worth monitoring. If you’re not, the report is shared via follow-up.
A door hanger and a Google Review refrigerator magnet are left at the property. Your before-and-after photos on the invoice help you track the transformation over time.
What Roof Cleaning Actually Costs in Queensbury, NY: Real Numbers, No Guesswork
Where Most Roof Cleaning Jobs Fall, Price-Wise
Roof cleaning starts at $400.
For large or complex roofs with steep pitches, heavy growth, or difficult access, pricing can reach $2,000 to $5,000+. Every job is custom-quoted because no two roofs are the same.
Nine Things That Shape Your Roof Cleaning Quote
Here is exactly what we evaluate when quoting your job:
- Roof size: Total square footage is the primary pricing driver.
- Pitch (steepness): Steeper roofs increase labor time and safety requirements.
- Accessibility: Whether the crew can walk the roof, must use a ladder, or needs a lift.
- Severity of growth: The density and age of moss, algae, or lichen coverage.
- Roof material: Asphalt shingles and slate are both cleaned, but the chemical concentration differs.
- Landscape sensitivity: Gardens, specialty decks, or mature plantings beneath the roofline require additional protection steps.
- Walkability: How safely a crew member can move across the surface.
- Number of hips and valleys. Complex rooflines demand more precise chemical placement.
- Ladder or lift requirements: Some jobs require aerial lift equipment, which adds to cost.
Save Money by Bundling Roof Cleaning with Other Services
Roof cleaning is our anchor service, and it’s the foundation of our bundle pricing model. When you book roof cleaning and add any additional service, whether it’s gutter cleaning, window cleaning, deck cleaning, patio cleaning, or house washing, bundle savings apply.
Gutter cleaning (starting at $199) is the most natural pairing, since clean gutters let the roof drain properly and extend the time before moss and algae begin to regrow.
Our Roof Cleaning Guarantee, and What It Does and Doesn't Cover
If moss, black streaks, or lichen are still visible after the mandatory 4 to 6 week observation period, we return and retreat affected areas at no charge. The waiting period is required because soft wash chemistry continues working after application.
Algae, moss, and lichen are killed at the cellular level, but the dead material washes away gradually with natural rainfall. Immediate results should not be expected. Lichen takes longer to die off than algae and may require more patience. If visible growth remains after 6 weeks, contact us. The retreatment guarantee applies.
This guarantee is not a time-limited warranty against regrowth. We do not offer a “results guaranteed for 12 months” promise. The environment, including tree cover, moisture, and freeze-thaw cycles, controls long-term longevity. What we guarantee is that the initial treatment will do its job. If it doesn’t, we come back.
By following ARMA’s recommended soft wash method, our cleaning process does not void your existing roof manufacturer warranty. High-pressure washing on asphalt shingles does void most manufacturer warranties. Our method is the approved alternative. This is especially important for homeowners with newer roofs or properties being prepared for sale.
What Queensbury Homeowners Say About Us
Frequently Asked Questions
Is roof cleaning the same as pressure washing?
No, and the distinction matters for your roof’s health and warranty. Pressure washing uses high-pressure water to force debris off surfaces. Roof cleaning uses a soft wash method: low pressure combined with a sodium hypochlorite and surfactant solution that kills algae, moss, and lichen at the cellular level without damaging shingles.
Will soft washing damage my asphalt shingles?
No. Soft washing is the only method recommended by shingle manufacturers and ARMA for removing algae, moss, and lichen from rooftops. We never use high-pressure equipment on any roofing surface. High-pressure washing strips granules, accelerates aging, and can void manufacturer warranties. Our soft wash method treats the growth at the source without mechanical force.
Does the chemical smell during the service?
Yes. Sodium hypochlorite has a noticeable smell during application. This is normal and expected. The odor fades as the chemical dries. We recommend keeping windows and doors closed while our crew is working on the roof.
Can soft washing remove lichen from my roof?
Yes, soft washing kills lichen using the same sodium hypochlorite solution used for algae and moss. The key difference is timing. Lichen adheres more deeply to the roof surface than algae, so it takes longer to die off and wash away after treatment. Plan for 6 to 8 weeks or longer for full lichen results compared to the standard 4 to 6 week window for algae. If visible lichen remains after that period, our satisfaction guarantee covers a free retreatment.
How long will my roof stay clean after treatment?
The honest answer is that it depends on your environment. Tree cover, moisture levels, and annual rainfall all influence how quickly algae, moss, and lichen begin to return. Properties with heavy overhanging trees and significant shade, common in the Adirondack region, will see regrowth sooner than open, sun-exposed roofs. We recommend monitoring your roof annually and considering regular tree trimming to slow the return of biological growth.
When is the best time of year to have my roof cleaned in Queensbury?
Two windows work well for Queensbury homeowners. Late spring to early summer, after pollen drops but before midsummer heat, is ideal for clearing winter buildup and treating growth before it spreads through the warm season.
How long does a roof cleaning take?
The average roof cleaning takes between one and three hours. Timing depends on the size and pitch of your roof, the severity of growth present, and the access method our crew uses. Larger or more complex roofs with steep pitches, extensive lichen, or multiple hips and valleys may take longer.
What conditions would prevent you from cleaning my roof?
We decline jobs on roofs that are structurally unsafe, have extremely brittle or deteriorated materials, show existing storm damage or active leaks, or have bare substrate exposed from granule loss. We also reschedule during heavy rain, as wet surfaces create unsafe conditions and reduce chemical effectiveness. If your roof has any of these issues, we’ll let you know during the estimate and recommend the appropriate next step.
Should I get my gutters cleaned at the same time as my roof?
Yes, and we strongly recommend it. After a roof cleaning, clean gutters allow the roof to drain properly and extend the lifespan of the results. Clogged gutters create standing moisture at the roofline, which accelerates the return of moss and algae. Our gutter cleaning service starts at $199, includes a downspout inspection, and pairs naturally as a bundled add-on with roof cleaning.
Don't Let Moss and Algae Set Up Camp Before Winter Hits
Queensbury homes average around 50 years of age, and clean shingles signal a well-maintained property to buyers and inspectors alike. Our team is owner-operated, fully insured, and every job is backed by our satisfaction guarantee and ARMA-compliant soft wash process.
