Soft Washing
Soft washing uses low-pressure water, typically 100-500 PSI, combined with biodegradable cleaners to remove contaminants gently without damaging delicate materials. This is a less abrasive cleaning method than pressure washing. Eco-friendly cleaning products contain quaternary compounds which penetrate deeply into porous surfaces and eliminate spores from the root.

The process starts with a thorough cleaning agent application that is active for between 45 and 60 minutes. Then a gentle rinsing to remove all residues, without forcing water underneath shingles. This method is especially effective for:
- Asphalt shingles with warranties from the manufacturer
- Historic cedar shake roofs
- Beautiful slate or clay tile installation
- Water conservation areas
Steam Cleaning
Steam cleaning is a powerful method of cleaning that can be used in commercial settings. It produces superheated steam that kills bacteria, mould spores and fungal networks. The process involves:
- Initial surface temperature assessment for optimal steam settings
- Application using heat-resistant extension wands
- Calculation of dwell times based on contamination severity
- Thermal imaging inspection is optional to ensure coverage
Steam cleaning is excellent on these surfaces
- When chemical residues pose a problem, metal roofing is a good option
- Sanitisation of solar panel installations without scratching
- Commercial structures with TPO and EPDM membrane roofs
- Materials that are historically important but require minimal moisture
Steam penetration dissolves waxy coatings that protect biological growth. On contact, high temperatures eliminate 99.9% pathogens. Water usage is minimised to reduce the risk of interior leaks. Processes that are chemical-free protect sensitive areas. Rapid evaporation reduces moisture exposure.
Pressure Washing
Controlled pressure washing produces exceptional results for a more durable roof. Technicians use commercial grade equipment with adjustable pressure settings (500-2500 PSI) and precise patterns to remove stubborn buildup through targeted water pressure.
Calibrated pressure settings are carefully based on:
- Roof age and composition
- Type and extent of contamination
- Surface porosity and condition
- Environmental factors
- UV stabilisers extend the treatment effectiveness up to 24 months
