0481 275 740Why Moss on Your Newcastle Roof Is a Serious Problem
Moss and lichen are not just cosmetic issues. Their root systems penetrate tile surfaces and grout lines, causing cracking, water ingress, and structural damage over time. Left untreated, moss can void your roof warranty and lead to costly repairs. Newcastle's humid climate and proximity to the coast makes roofs particularly vulnerable.
Professional Roof Cleaning Services in Newcastle
WSI Cleaning uses a soft wash system — low-pressure water with biodegradable biocide solutions — to safely remove moss, algae, lichen, and grime from all roof types. Unlike high-pressure washing, our method won't crack tiles, strip protective coatings, or force water under your roof membrane.
Concrete Tiles
The most common roof type in Newcastle. Our soft wash removes moss and algae without damaging the tile surface or colour coating.
Terracotta Tiles
Heritage and modern terracotta tiles cleaned with care. Low-pressure system protects the natural finish and prevents breakage.
Colorbond Metal
Metal roofing cleaned with appropriate pressure settings and solutions safe for the Colorbond coating.
Moss & Lichen Removal
Biodegradable biocide kills organisms at the root, preventing rapid regrowth and extending results.
Roof Restoration Prep
Cleaning before repainting or re-coating ensures proper adhesion and a professional finish.
Solar Panel Cleaning
Combine your roof clean with solar panel cleaning for a complete roof service.
