Wellington’s stunning coastal location and vibrant weather patterns make it a beautiful place to live — but tough on roofs.
If you’ve noticed moss growth, grime streaks, or fading on your roof, you’re not alone. The region’s wind, salt air, and damp winters accelerate roof wear, even on newer homes.

At Metro Water Blasting, we provide expert soft wash roof cleaning services that extend your roof’s life, boost your home’s appearance, and protect your property’s value.

Here’s why soft washing is the smartest choice for Wellington homeowners — and what makes local roof cleaning different from anywhere else in New Zealand.

The Wellington Roofing Challenge: Salt, Moss, Wind, Repeat

Environmental Factor Roof Impact
Coastal salt air Accelerates corrosion, particularly on metal roofs
Frequent windstorms Carry debris into valleys and gutters
Winter moisture Encourages moss, algae, and lichen growth
UV exposure Fades coatings, breaks down membranes

Even low-slope roofs or Colorsteel installations degrade faster in Wellington than in drier, inland cities like Hamilton or Rotorua.

Why Moss is More Than Just Cosmetic

You might think moss is only an aesthetic issue — but it’s much worse than that.

  • Moss and lichen retain water, keeping your roof damp 24/7
  • Root systems burrow into tile and membrane surfaces, weakening structural layers
  • In freezing conditions, trapped water expands, cracking roof materials from the inside out

✅ That’s why Metro Water Blasting uses biocide-based soft washing — killing moss at the root without harming your roofing materials.

The Dangers of High-Pressure Roof Cleaning

High-pressure washing might seem like a fast solution — but it can be disastrous for Wellington homes.

Roof Type High Pressure Risk
Concrete Tile Chips, cracks, dislodged tiles
Colorsteel Strips protective coatings, invites rust
Decramastic (chip) Loosens stone chips, exposes bare metal
Asphalt Shingle Breaks granules, leads to leaks

✅ Soft washing uses low pressure and targeted treatments, keeping your roof intact while delivering a deep clean.

At Metro Water Blasting, every Wellington roof clean includes:

  • ✅ Full visual inspection of tiles, flashings, and gutter lines
  • ✅ Application of biodegradable cleaning agents to break down moss, algae, and dirt
  • ✅ Low-pressure rinse to preserve delicate surfaces
  • ✅ Optional gutter clean and downpipe flush to protect drainage
  • ✅ Report on any visible damage for early intervention
