Owning a home in Auckland is a major investment — but between the city’s coastal salt spray, heavy rains, intense UV exposure, and stormy winters, keeping your exterior clean and protected is a real challenge.
At Metro Water Blasting, we know that exterior cleaning is not just about curb appeal — it’s about preventing expensive damage and preserving your property value for years to come.
In this ultimate guide, you’ll learn everything you need to know about:
- Roof cleaning
- Gutter maintenance
- House washing
- Driveway and deck cleaning
- And more!
Let’s dive in and make sure your Auckland home stays beautiful — and structurally sound.
Why Exterior Cleaning Matters So Much in Auckland
Auckland’s unique environment constantly attacks your home:
- Salt Air: Accelerates corrosion of roofs, gutters, and cladding.
- Frequent Rain: Promotes moss, lichen, and mould growth.
- UV Radiation: Fades paint, dries timber, and weakens roofing materials.
- Windstorms: Dump debris into gutters and valleys.
Neglecting regular cleaning means facing premature repairs, roof replacements, and lower property values.
Roof Cleaning: Protecting Your First Line of Defense
Your roof shields your home from the elements — but it’s constantly under attack.
Common Roof Problems in Auckland
✅ Moss and lichen buildup
✅ Salt corrosion on metal roofs
✅ Blocked valleys causing leaks
✅ Tile cracks hidden under moss mats

Why Professional Roof Cleaning Matters
✅ Soft washing techniques preserve delicate tiles, membranes, and paints.
✅ Eco-friendly treatments kill moss and lichen at the root, preventing regrowth.
✅ Drainage inspections ensure stormwater flows properly off the roof.
Without cleaning, moss roots penetrate roof materials, causing leaks, insulation damage, and structural rot.
Gutter Cleaning: Your Home’s Hidden Guardian
Gutters are vital for channeling rainwater safely away from your home. When clogged, they create massive problems.
Risks of Blocked Gutters in Auckland
✅ Roof leaks into ceiling spaces
✅ Water staining on exterior walls
✅ Rotted fascia boards and soffits
✅ Flooding around foundations

Signs You Need Gutter Cleaning Now
- Water overflowing during rain
- Plants or moss growing in gutters
- Gutters pulling away from the house
- Water pooling around your foundations
✅ Regular gutter cleaning prevents tens of thousands of dollars in future damage.
House Washing: Keeping Your Exterior Fresh and Protected
Dirty, stained, or mouldy cladding doesn’t just look bad — it shortens the lifespan of your exterior paint and materials.
Why Auckland Homes Get Dirty Faster
- Coastal salt sticks to walls and windows.
- Humidity grows moss, mildew, and algae.
- Traffic dust and grime coat urban homes.
Benefits of Regular House Washing
✅ Protects your home’s paintwork and cladding
✅ Removes allergens and mould spores
✅ Boosts property value
✅ Reduces maintenance costs over time
✅ Soft house washing techniques are safe for weatherboard, brick, plaster, and painted surfaces.
Driveway, Deck, and Fence Cleaning
It’s not just your house that needs care — your outdoor surfaces do too.
Risks of Dirty Driveways and Decks
✅ Slippery moss growth creates hazards.
✅ Algae buildup stains timber and concrete.
✅ Pollutants eat into surface materials.
✅ Professional driveway cleaning and deck washing keep your entire property safe and attractive.
How Often Should You Schedule Exterior Cleaning?
| Surface | Recommended Frequency |
|---|---|
| Roof Cleaning | Every 12–18 months (6–12 months if coastal) |
| Gutter Cleaning | Every 6 months (more often after storms) |
| House Washing | Every 12 months |
| Driveway & Deck Cleaning | Every 12–18 months |
✅ Remember: homes near the coast (like Mission Bay, Takapuna, or Hobsonville) need more frequent cleaning.
Why DIY Cleaning Isn’t Enough
While DIY might sound tempting, it’s risky:
- High-pressure washing can damage paint, roofs, and cladding.
- Incomplete gutter clearing leaves hidden blockages.
- Incorrect moss treatments only kill surface growth, not roots.
- Working at heights without proper safety equipment is dangerous.
✅ Professional exterior cleaning ensures deep, safe, long-lasting results.
