There are several factors we take in to consideration when deciding which safe and effective cleaning method we employ. As, different roof cleaning methods are not always suitable for all types of roof, including soft washing. So, we look at the specific needs of your roof and depending on the type of roof, material, and the specific issues present. This is to avoid causing damage to your roof tiles when we clean your roof.
- Soft Washing: Utilises low-pressure water combined with biodegradable cleaning solutions to gently remove contaminants without damaging delicate materials.
- Pressure Washing: Applied selectively on appropriate surfaces, this method effectively removes stubborn build up through controlled water pressure.
- Chemical Treatments: Specialised formulations that target specific organisms like algae or moss while maintaining roof integrity.
- Manual Removal: Careful hand-cleaning for delicate areas or historical roofs where mechanical methods might cause damage.
Each property presents unique challenges, which is why our technicians thoroughly assess your roof’s condition before determine the best cleaning method. The wrong technique can potentially cause more harm than good, particularly on aging or fragile materials. You don’t get your roof cleaned every day, so hiring a professional will avoid expensive repairs
Professional cleaners apply appropriate techniques. Proper equipment ensures thorough cleaning. Clean roofs (prevent) water damage.

Our certified technicians at UpClean are trained to evaluate which method will provide optimal results for your specific roofing material while ensuring the safety and integrity of your property. We prioritise both effectiveness and long-term roof protection in every project we undertake.
Professional maintenance not only improves your home’s appearance but also prevents costly repairs down the line. By employing the right roof cleaner that assess your roof and applies the right roof cleaning method, it will extend the lifespan of your roof. In fact, regular cleaning typically extends roof lifespan by 5-10 years, representing significant savings compared to premature replacement costs.
Choose the Right Roof Cleaning Methods for your Home
Soft Washing
Soft washing utilises low-pressure water (typically 100-500 PSI) combined with biodegradable cleaning solutions to gently remove contaminants without damaging delicate materials. It is a professional cleaning service that is less abrasive than traditional pressure washing. Our proprietary eco-friendly cleaning solution contains quaternary ammonium compounds that penetrate deep into porous surfaces to eliminate spores at the root level.
The process begins with a thorough pre-treatment that loosens accumulated debris, followed by the application of our specialised cleaning agent that remains active for 45-60 minutes. We then perform a gentle rinse that removes all residues without forcing water under shingles. This method is particularly effective method for:
- Asphalt shingles with manufacturer warranties
- Historical cedar shake roofs
- Delicate slate or clay tile installations
- Areas with strict water conservation regulations
Soft washing preserves manufacturer warranties. Biodegradable solutions (protect) surrounding vegetation. Low pressure prevents water intrusion. It is gentle to the surface of your roof, provides effective cleaning without causing any damage.
Steam Cleaning
When it comes to roof cleaning, steam cleaning represents the cutting edge of roof maintenance technology in our arsenal at UpClean. This innovative method harnesses the power of high-temperature vapor (280°-320°F) delivered at controlled pressure to effectively sanitise and restore roofing surfaces without chemical additives.
Our commercial-grade steam cleaning equipment generates superheated vapor that instantly kills biological contaminants including mould spores, bacteria, and fungal networks that traditional methods might miss. The process involves:
- Initial surface temperature assessment to determine optimal steam settings
- Systematic application using specialised heat-resistant extension wands
- Targeted dwell time calculations based on contamination severity
- Optional thermal imaging inspection to ensure complete coverage
Steam cleaning excels on these surfaces:
- Metal roofing where chemical residues are a concern
- Solar panel installations requiring sanitisation without scratching
- TPO and EPDM membrane roofing on commercial structures
- Historic materials where minimal moisture introduction is essential
The thermal properties of steam provide unique advantages in our comprehensive cleaning program:
Steam penetration dissolves waxy protective coatings of biological growth. High temperature eliminates 99.9% of pathogens on contact. Minimal water usage reduces potential for interior leakage. Chemical-free process safeguards sensitive environmental areas. Rapid evaporation prevents prolonged moisture exposure.
This method is particularly valuable for properties with rainwater collection systems, sensitive landscaping, or strict environmental compliance requirements. While the equipment investment is substantial, the reduced water consumption (up to 95% less than conventional methods) and elimination of chemical runoff make steam cleaning an environmentally superior option.
Pressure Washing
For more resilient roof, controlled pressure washing delivers exceptional results. Our technicians utilise commercial-grade equipment capable of adjustable pressure settings (500-2500 PSI) and precise spray patterns to effectively remove stubborn build up through targeted water pressure.
We carefully calibrate pressure settings based on:
- Roof composition and age
- Extent and type of contamination
- Surface porosity and condition
- Surrounding environmental factors
Pressure washing is ideal for concrete tiles, certain metal roofing systems, and composite materials specifically rated for high-pressure cleaning. Our technicians maintain strict adherence to manufacturer guidelines regarding maximum recommended PSI, ensuring that your roof remains in good condition after the roof is cleaned.
Pressure washing removes heavy accumulation. Adjustable settings accommodate various materials. Targeted application minimises water usage. Professional equipment reaches inaccessible areas.
Chemical Treatments
Our chemical treatment is a method that involves specialised formulations that target specific organisms while maintaining integrity of your roof. We utilise a tiered approach based on contamination severity:
Tier 1: Preventative Treatment
- Zinc or copper-based solutions that create an inhospitable environment for biological growth
- Applied bi-annually on north-facing slopes susceptible to algae
- pH-balanced formulations safe for downspout collection systems
Tier 2: Active Remediation
- Oxygen-based cleaners that break down organic matter at the molecular level
- Surfactant additives that improve penetration and coverage
- UV stabilisers that extend treatment efficacy up to 24 months
Tier 3: Advanced Restoration
- Professional-grade sodium hypochlorite solutions (carefully diluted to 5-8%)
- Specialised stain removers for tannin and metal oxide discoloration
- Neutralising agents applied post-treatment to restore optimal pH levels
Chemical solutions eliminate microscopic spores. Preventative treatments create hostile environments for regrowth of moss and algae. Professional application ensures even coverage. Timed neutralisation protects plants and shrubs plus other landscaping elements.
Manual Removal
For heritage properties or significantly damaged roofing systems, our manual cleaning methods are ideal. This labour-intensive approach doesn’t use a lot of water to remove dirt, moss or algae. This method uses:
- Hand scraping using non-metallic tools specially contoured for each roofing profile
- Gentle brushing with natural fibre implements to preserve surface texture
- Spot treatment of persistent stains using targeted applications
- Sequential cleaning patterns to prevent cross-contamination between sections
This meticulous process is particularly valuable for historically significant structures, extremely weathered materials, or roofs with existing damage that could be exacerbated by mechanical methods.
Manual techniques preserve historical integrity. Specialised tools prevent surface abrasion. Targeted treatments address problem areas. Methodical approach minimises material displacement.
