Denver’s high-altitude sun, sudden hail storms, heavy snow, strong winds, and dry air cause dirt buildup, algae streaks, lichen growth, and debris accumulation on residential roofs. These contaminants darken appearance, trap moisture after snowmelt, and can shorten material life if ignored. Safe, effective cleaning removes buildup, restores color, and supports roof longevity. We serve homeowners in Denver, Aurora, Lakewood, Littleton, Centennial, Arvada, Westminster, Thornton, Highlands Ranch, Parker, and nearby communities within a 50-mile radius.
Our roof cleaning is performed exclusively for residential properties—single-family homes, townhouses, and condos—using low-pressure techniques and solutions tailored to Colorado’s roofing materials and climate.
Benefits of Our Cleaning Service
Revitalized Home Appearance
Eliminating dark streaks, dirt, and lichen instantly brightens your roof, boosting curb appeal against Denver’s clear blue skies and mountain views.
Prolonged Roof Durability
Removing debris and organic growth prevents moisture retention that leads to granule loss or underlayment damage, especially after spring snowmelt or summer storms.
Reduced Risk of Damage
Regular cleaning minimizes weight from accumulated dirt and pine needles while slowing algae that thrives in shaded areas along the Front Range.
Support for Overall Roof Health
A clean surface improves reflectivity to combat intense UV exposure and helps maintain proper ventilation in attics affected by temperature swings.
Primary Areas We Clean
Asphalt Shingles
Common black streaks from algae and embedded dirt are treated and removed without stripping protective granules.
Concrete or Clay Tiles
Lichen, moss patches, and airborne pollutants are cleared while preserving tile integrity popular in many Colorado homes.
Gutters and Downspouts
Pine needles, leaves, and hail debris are flushed to restore flow and prevent ice dam precursors in winter.
Roof Valleys and Low Spots
Areas prone to trapping water or debris after storms are thoroughly cleaned for proper drainage.
Vents and Flashing Zones
Surrounding buildup is removed to maintain clear airflow and seals.
Overall Surface Debris
Loose twigs, pollen, dust, and urban pollutants are safely washed away.
Step-by-Step Cleaning Process
Pre-Cleaning Evaluation
We assess roof type, pitch, material condition, buildup severity, and surrounding trees or hail history to select the safest, most effective method for your specific home.
Property Protection Measures
Landscaping, windows, siding, patios, and driveways are covered with tarps and shields. Delicate plants and outdoor features common in Denver yards are safeguarded against runoff.
Targeted Solution Application
An environmentally responsible cleaning solution is applied at low pressure to loosen dirt, kill algae, and dissolve lichen without harsh chemicals that could harm Colorado’s dry ecosystem.
Soft-Wash Rinsing
Controlled low-pressure rinsing removes loosened contaminants while protecting shingles or tiles from granule loss or cracking—far gentler than high-pressure methods.
Manual Debris Clearing
Larger items like branches, needles, or hail residue are hand-removed, followed by thorough gutter flushing to ensure unrestricted water flow during thunderstorms or snowmelt.
Post-Cleaning Inspection & Site Restoration
We verify complete coverage, rinse surrounding areas to neutralize residue, remove all protective coverings, bag debris, and leave your property immaculate—including blowing off walkways.
Frequently Asked Questions
How often should Denver roofs be cleaned?
Every 2–4 years is typical, depending on tree cover and sun exposure. Homes with heavy pine shade or north-facing slopes often benefit from more frequent attention to stay ahead of algae and lichen.
What causes those dark streaks on my shingles?
They’re usually from airborne algae (Gloeocapsa magma) that feeds on limestone filler in shingles—accelerated by moisture after snow or rain. The good news: they’re fully removable with proper treatment!
Is soft-wash cleaning safe for my roof?
Absolutely—our low-pressure approach avoids damaging granules or tiles, unlike aggressive pressure washing that can shorten roof life in our intense sun.
Will the solution harm my landscaping?
We use plant-safe, biodegradable products and thoroughly cover/protect plants, watering them before and after. Most homeowners are impressed with how carefully we safeguard their yards.
How long does the cleaning take?
Most homes are completed in one day—typically 4–8 hours based on size and buildup. We work efficiently and coordinate around your schedule.
Can you clean during Colorado’s variable weather?
We monitor forecasts closely and prefer clear, mild days for best results and safety. Spring and fall are ideal, but we’re flexible year-round when conditions cooperate.
Do you clean gutters as part of the service?
Yes—gutter and downspout clearing is always included to ensure proper drainage, especially important before winter snow or summer hail seasons.
Do you serve homes outside central Denver?
We’re glad to! We cover residential properties within 50 miles, including Aurora, Lakewood, Littleton, Centennial, Arvada, Westminster, Thornton, Highlands Ranch, Parker, and surrounding areas.
