As autumn settles across New Zealand, falling leaves, cooler temperatures, and increased rainfall signal that winter is just around the corner. While many homeowners focus on indoor preparation, exterior maintenance is just as important during this time of year.
Autumn is the ideal time to clean, inspect, and maintain your home’s exterior before heavy winter weather arrives. Without proper maintenance, blocked gutters, moss-covered roofs, and dirty surfaces can lead to costly damage during the wetter months.
At Metro Water Blasting, we provide professional exterior cleaning services across New Zealand including Auckland, Wellington, Christchurch, Tauranga, and Hamilton. This autumn checklist will help you prepare your property and avoid common winter problems.
Why Autumn Exterior Cleaning Is So Important
Autumn creates the perfect conditions for debris buildup and organic growth.
Common seasonal issues include:
• Leaves blocking gutters and downpipes
• Moss and lichen growing on roofs
• Damp conditions causing mould on exterior walls
• Slippery surfaces around driveways and paths
• Increased moisture leading to long-term damage
By addressing these issues early, homeowners can protect their properties and avoid expensive repairs.
1. Clean Your Gutters and Downpipes
Gutter cleaning is one of the most important maintenance tasks during autumn.
Falling leaves, twigs, and debris can quickly block gutter systems, preventing rainwater from draining properly.
Blocked gutters can cause:
• Water overflowing onto walls
• Roof leaks and internal damage
• Rotting fascia boards
• Foundation water issues
Professional gutter cleaning ensures your drainage system is clear and ready for winter rainfall.

2. Remove Moss, Mould and Lichen from Your Roof
Autumn moisture creates ideal conditions for moss and lichen growth on roofs.
If left untreated, this can:
• Trap moisture on roofing surfaces
• Damage tiles and coatings
• Block gutters with falling debris
• Reduce roof lifespan
A professional roof treatment kills moss and prevents regrowth over time.

3. Wash Exterior Walls Before Winter
Over time, homes accumulate dirt, mould, and grime. Autumn is the best time to remove this buildup before winter moisture sets in.
Professional house washing:
• Removes mould and mildew
• Restores exterior appearance
• Protects paint and cladding
• Prevents long-term staining

5. Check for Drainage Issues Around Your Home
Autumn is a good time to inspect how water flows around your property.
Check for:
• Blocked downpipes
• Water pooling near foundations
• Overflowing gutters
• Poor drainage areas
Addressing these issues early helps prevent flooding and water damage during winter.
6. Trim Trees and Reduce Debris Build-Up
Overhanging branches contribute significantly to gutter blockages.
Trimming trees around your home:
• Reduces leaf buildup
• Prevents branches damaging roofs
• Improves sunlight exposure
• Reduces moss growth
7. Prevent Mould Growth on Exterior Surfaces
Damp conditions during autumn and winter can lead to rapid mould growth.
Regular cleaning helps:
• Remove existing mould
• Prevent regrowth
• Maintain a clean appearance
• Protect exterior surfaces
8. Prepare Rental or Investment Properties
Autumn maintenance is especially important for rental properties.
Regular exterior cleaning:
• Keeps properties well maintained
• Reduces long-term repair costs
• Improves tenant satisfaction
• Protects your investment
