How Storms Damage Your Roof and What to Do About It

Auckland's weather can turn quickly. One moment it's calm, the next your roof is taking a beating from wind, rain and flying debris.

After a storm, your roof might look fine from the ground, but hidden damage can cause serious problems later.

1. Wind Damage to Roofing Materials

Strong gusts can lift and dislodge roof panels, especially on older homes or poorly fastened sections.

Signs of wind damage:

• Loose or lifted long run steel sheets
• Missing or curled shingles
• Bent or flapping flashings
• Roof sections that appear uneven

Wind pressure often targets the edges of your roof, so pay close attention to corners and overhangs during your inspection.

2. Heavy Rain and Roof Leaks

Auckland storms often come with torrential rain. If your roof has any weak points, water will find its way in.

What to look for:

• Water stains on your ceiling or walls
• Dripping during or after rain
• Damp smells in the attic
• Mould near rooflines

If left untreated, moisture from a storm can lead to timber rot, sagging ceilings and even electrical issues.

3. Gutter Overflow and Drainage Problems

When rain falls fast, your gutters and downpipes need to work efficiently. Blocked or undersized gutters can overflow.

Common storm related gutter issues:

• Debris clogging the gutter
• Downpipes not draining fast enough
• Water pooling near the foundation
• Damp patches below the eaves

4. Falling Trees and Impact Damage

Storms often bring down branches or even entire trees. Impact damage from falling debris is one of the most serious forms of roof damage.

Signs of impact damage:

• Dents or punctures in metal roofing
• Cracked or broken shingles or tiles
• Visible holes or roof sagging
• Debris lodged in roof valleys

5. Flashing and Sealant Failure

Flashings seal the joints around chimneys, skylights and roof edges. In high winds, these can come loose or lift.

Warning signs:

• Rust or stains around flashings
• Visible gaps or lifting edges
• Water marks near chimneys or vents
• Mould growth in corners of ceilings

What to Do After a Storm

1. Do a visual check from the ground

2. Don't climb onto the roof - wet roofs are dangerous

3. Check your ceilings and attic for signs of leaks

4. Call a roofing professional

5. Contact your insurance provider if there's visible damage
