Yes, it is bad to have leaves on your roof. Leaves accumulating on your roof can retain moisture, leading to mould and mildew growth. During damp weather, this can exacerbate roofing material degradation.

Over time, these damp leaves can cause rot in wooden structures and corrode metal fastenings. Additionally, leaves can block gutters, causing water to overflow and potentially damage your home’s foundation or exterior walls.

That’s why gutter cleaning companies regularly clear leaves from roofs and gutters to extend roofing lifespan.

For this post, we’ll talk more about having leaves on the roof and why you should address them immediately.

How Do Leaves Cause Roofing to Leak?

Leaves can cause roofing to leak by trapping moisture against the roof surface. During the wet season, accumulated leaves become damp and form a mat. This prevents water from evaporating or running off, keeping the roof perpetually wet underneath.

Extended exposure to this moisture can lead to the deterioration of roofing materials, making them more susceptible to cracks or breaks. Over time, these weak spots can become avenues for leaks into the home.

What Happens If I Don’t Clean Leaves From My Roof?

These are the main issues you’ll face if you don’t clean leaves from your roof:

Moisture Accumulation and Rot

When leaves pile up on your roof, they trap moisture beneath them. This damp environment, especially in moisture-prone areas like the Mornington Peninsula, can lead to the rotting of roofing materials. Wood structures can weaken and decay, while roofing shingles may warp or degrade faster than they normally would.

Blocked Gutters and Water Damage

Leaves can easily clog gutters and downspouts. Blocked gutters prevent rainwater from flowing away properly, leading to water overflow. This can result in water seeping into the eaves, walls, or foundation, causing potential structural damage to your home. Moreover, stagnant water in gutters becomes a breeding ground for pests and insects.

Growth of Mould and Mildew

The moisture retained by the accumulated leaves creates an ideal environment for mould and mildew growth. This can spread to roofing materials and even the interior of your home. Besides potential health risks, mould can cause structural issues, deteriorate indoor air quality, and is costly to remediate.

Can I Prevent Leaves From Falling On My Roof?

No, you cannot prevent leaves from falling on your roof entirely, as this is a natural occurrence, especially in areas with trees. However, you can minimise the accumulation by trimming overhanging branches or considering strategic landscaping.

Additionally, installing gutter guards or screens can help reduce the number of leaves settling on your roof and gutters.
