As we lean towards winter, we have a seemingly endless checklist of seasonal tasks: raking fallen leaves, checking for drafts, winterizing systems, the list goes on and on. Yet, one job often goes unnoticed—the removal of dead leaves, tree branches, and pine needles from our roofs.
A recent study revealed that 71% of homeowners had $500 or less saved for emergency repairs, highlighting how important it is to prioritize upkeep.
Below are the biggest risks of leaving leaves on roofs and why leaf removal matters.
1. Water Damage
Leaf buildup can trap moisture.
At first, it may look harmless, but it increases the chance of water damage.
Before the first snow, clear dead leaves and wet leaves to protect your home and avoid costly repairs.
“The water damage from not removing leaves from a roof can be destructive," warns Mike Thomas, CARE Training Lead at GAF. "Roofing systems are intended to be water-shedding, allowing it to drain downward and away from a house. Leaves can get in the way of water being able to drain properly from a roof, which can lead to water infiltration into a home and visible damage to the framing, roof sheathing, and insulation."
He expands to the topic of energy efficiency. "This deterioration over time can also affect the R-value of the insulation, making a home less energy efficient, and in colder climates, increases the risk of ice dams, which can cause significant damage to both roofs and the interior of homes."
2. Structural Damage
When fallen leaves, wet leaves, and snow collect on your roof, the extra weight can strain the structure underneath. Over time, this buildup can weaken the roof system and create sagging areas.
"Any dips and waves that you see on your roofline indicate that the building underneath has lost its strength," shared Jordan Lee, owner of Superior Gutter and Roofing. "These spots collect water and snow and load up with unsafe weights that can cause collapse in enormous winter storms."
What may start as a small dip in the roofline can quickly grow into a serious problem. Once water pools in these areas, it increases the chance of roof damage and may lead to expensive repairs or even collapse during heavy storms.
3. Clogged Gutters
Blocked gutters cause a chain of issues. Tree debris and damp leaves add weight and trap water, leading to damage to both gutter systems and roofing materials.
"Wet leaves can also erode the mineral granules on roofing shingles, causing the granules to fall into the gutter over time," shares Thomas.
Problems caused by clogged gutters include:
- Water runoff: Pooling near the foundation can cause basement flooding, foundation cracks, and landscape erosion.
- Ice dams: In colder areas, clogged gutters contribute to ice dam formation. This leads to leaks, roof damage, and interior water stains.
- Mold and mildew growth: Standing water encourages mold growth, which can spread to exterior walls and raise health concerns.
4. Pests
A pile of leaves can look harmless, but it attracts insects, rodents, and birds. Once they settle in, they can damage roof shingles and even your home’s structure. Cold weather pushes pests to find warm spaces, and your roof becomes an easy shelter.
Not Sure if Your Roof is Damaged?
"A trained eye will be able to see problems you may overlook at ground level," noted Lee, underscoring the importance of calling a certified roofing professional when you need help. "Fall is the ideal time to inspect, so you have time to get any repairs you need to get done before winter."
A professional roof inspection can reveal hidden roof damage before snow and ice make it worse.
The Importance of Safe Leaf Removal
Every fall season, schedule leaf removal to keep your roof clear.
For low-pitched roofs, homeowners can use:
- A leaf blower
- A roof rake with an extension pole
Both tools help clear debris without climbing on steep roof surfaces.
But be cautious:
- Climbing on a roof is dangerous
- Falls are the second leading cause of unintentional injury deaths among adults
"A highly experienced certified roofing professional knows how to navigate these areas and avoid injury during the process," highlights Thomas. "As an added benefit, having a professional roofing contractor complete this service gives the opportunity for a full inspection and evaluation of the condition of the roof where they can identify potential issues such as maintenance concerns or any storm damage that may have occurred."
As the autumn leaves fall, remember that they bring hidden risks. Clearing them as a preventive measure is one of the simplest forms of roof maintenance. Whether you use a roof rake from the ground or hire a roofing professional, keeping up with roof cleaning and gutter cleaning will protect your home.
Your roof (and your wallet) will thank you.
