Roof Cleaning Wigram – Professional Roof Maintenance
Wigram is one of Christchurch’s fastest-growing suburbs — and with its mix of new and established homes, roof maintenance is critical to protecting property value.
Dust, moss, lichen, and coastal winds slowly attack your roof, whether you have a tile or metal surface.
At Metro Water Blasting Christchurch, we provide professional roof cleaning services in Wigram, helping homeowners maintain strong, leak-free, long-lasting roofs without the risks of high-pressure blasting.
Why Roof Cleaning Is Essential in Wigram
Wigram’s open subdivisions and flat plains location create unique challenges:
- Wind-driven dust from nearby construction sites settles on roofs.
- Rain and humidity promote moss, lichen, and black algae growth.
- Coastal moisture from Christchurch’s easterly winds accelerates surface staining.
- Frost cycles in winter expand cracks and allow moss roots to deepen.
Without cleaning, moss and debris trap moisture, leading to:
- Rust on metal roofs
- Tile cracking and lifting
- Gutter blockages and overflows
- Water leaks into ceilings and walls
Common Signs Your Wigram Roof Needs Cleaning
- Green moss clumps around tile ridges or seams
- Black streaks running down Colorsteel roofing
- Grey-white lichen patches spreading across surfaces
- Overflowing or sagging gutters packed with moss
- Dark patches appearing inside ceilings or eaves
Catch it early — clean safely — protect your investment.
Our Roof Cleaning Process
We use a safe, non-invasive method that protects your home:
1. Full Roof Inspection
We assess the material type (tile, iron, Colorsteel) and organic buildup level.
2. Eco-Friendly Treatment Application
We spray a biodegradable solution that kills moss, algae, and mould at the root — with no damage to roofing materials.
3. Natural Rain Breakdown
Over 4–8 weeks, dead moss and grime wash away naturally without needing harsh water blasting.

How Often Should You Clean Your Roof in Wigram?
| Roof Type / Conditions | Cleaning Frequency |
|---|---|
| Tile roofs near gardens or trees | Every 12–18 months |
| Colorsteel roofs in open areas | Every 2–3 years |
| Homes exposed to dust or salt air | Annually recommended |
| After visible moss or staining appears | Immediate treatment needed |
Staying ahead of moss protects both the roof’s appearance and its structural integrity.
Real Client Story: Roof Revival in Wigram
A family in Wigram contacted us after their three-year-old Colorsteel roof started developing black algae streaks and moss buildup around the gutterlines.
Our eco-friendly roof treatment safely killed all organic material, restoring the bright Colorsteel finish without damaging the surface.
