   Cause: Accumulation of leaves, branches, moss, and other debris, especially in homes surrounded by native bush or near pine trees.

   Sym  ptoms:

• Water spilling over the gutter edge
• Sagging or bowing sections
• Water stains on exterior walls

   Impact:

• Fascia board damage
• Soil erosion around the foundation
• Roof leaks and mold growth

   Solution:

• Install gutter guards or leaf filters
• Schedule seasonal cleaning, especially in autumn and spring
• Use a wet/dry vacuum or pressure hose for efficient cleaning

2. Sagging Gutters

Cause: Weight from debris or water, inadequate support brackets, or old age.

Symptoms:

• Visible dip or bend in the gutter
• Gutters pulling away from the fascia board

Impact:

• Poor drainage and water pooling
• Risk of detachment during storms

Solution:

• Reinforce with new hangers or brackets
• Use heavy-duty aluminum or steel brackets designed for high rain zones
• Evaluate slope and alignment to ensure proper drainage

3. Corroded Gutters

Cause: Constant moisture, salt-laden air (especially near Auckland’s coastlines), and outdated materials.

Symptoms:

• Rust spots
• Visible holes or perforations
• Water leakage even during light rain

Impact:

• Leaks damaging fascia and soffits
• Premature system failure

Solution:

• Replace with rust-resistant materials like Colorsteel®, aluminum, or zincalume
• Apply a protective sealant if replacement isn’t an option
• Consider switching to seamless gutters, which are more durable

4. Incorrect Gutter Slope

Cause: Poor installation, structural shifts in the house, or DIY errors.

Symptoms:

• Water pooling in certain sections
• Overflow without blockage

Impact:

• Increased weight and sagging
• Debris accumulation
• Mildew or mosquito breeding spots

Solution:

• Reposition brackets for a consistent downward slope (1/4 inch per 3 meters)
• Hire a professional to inspect gutter alignment

5. Leaking Gutters

Cause: Cracks, joint separation, corroded spots, or wear and tear over time.

Symptoms:

• Water dripping during dry weather (residual)
• Stains or puddles under gutter joints

Impact:

• Damage to siding and foundation
• Wasted water

Solution:

• Seal joints using silicone-based gutter sealant
• For larger holes, patch with aluminum flashing or replace the section
• Replace old sectional gutters with seamless options

6. Overflowing Gutters

Cause: Undersized gutters, blocked downpipes, or torrential downpours exceeding gutter capacity.

Symptoms:

• Water gushing over the edge during rain
• Basement flooding
• Soil erosion near walls

Impact:

• Landscape damage
• Mold, mildew, and structural issues

Solution:

• Upgrade to larger capacity gutters (e.g., 150mm wide)
• Add additional downpipes
• Install rain diverters or splash blocks to control overflow

7. Pest and Bird Nesting

Solution:

• Install bird spikes or netting
