Commercial Roof Moss Treatment Services
Avello Group delivers specialist moss and biological growth treatment for commercial roofs across Melbourne, Sydney and Brisbane:
Moss & Lichen Removal
Physical removal and chemical treatment of established moss and lichen colonies on Colorbond, tile and metal commercial roofs. Safe removal methods that do not damage existing roof coatings or substrate.
Biocide Treatment & Regrowth Prevention
Post-removal biocide application to treated roof surfaces — killing remaining spores and preventing regrowth for 12–24 months. Significantly extends the period between cleaning cycles.
Gutter & Drainage Clearing
Removal of moss, lichen and debris from gutters and downpipes as part of a comprehensive roof moss treatment program — preventing blockages that accelerate moss growth on roof surfaces.
Annual Maintenance Programs
Structured annual roof moss treatment programs for commercial properties — catching and treating growth early before it causes coating damage, tile lifting or water ingress.
Why Roof Moss Treatment Matters
Moss and lichen cause progressive damage to commercial roofs when left untreated:
• Moss root structures penetrate coating systems and tile surfaces, causing cracking, lifting and coating failure
• Retained moisture under moss colonies accelerates corrosion of metal roofs and rotting of timber roof structures
• Blocked gutters from moss and debris cause overflow and water damage to walls, ceilings and foundations
• Untreated growth spreads across the entire roof surface over time, making treatment increasingly costly
A proactive annual moss treatment program is significantly cheaper than the remediation costs that follow years of untreated growth.
