Protect Your Home: Plastic Roof Vents and Wildlife Damage

17 June 2024


Protect Your Vents From Wildlife Damage

Plastic roof vents are a common feature in many homes, providing essential ventilation for attics and maintaining air circulation. However, these vents are not without their vulnerabilities, especially wildlife damage. Wildlife, particularly raccoons and squirrels, often target plastic roof vents, creating a gateway into your home. Understanding how these animals exploit roof vents and learning how to protect your home from wildlife damage is crucial for any homeowner.

Raccoons: Master Pullers

Raccoons are known for their intelligence and dexterity. These nocturnal creatures can easily climb onto roofs and locate plastic vents. Once they find a vent, their powerful paws and sharp claws make quick work of pulling off the vent cover. Raccoons are motivated by the warmth and safety attics offer, as well as the possibility of finding food. Once inside, they can cause significant damage to insulation, wiring, and other attic components.

Squirrels: Persistent Chewers

Squirrels, on the other hand, pose a different threat. These agile animals can easily reach roof vents and, with their strong and ever-growing teeth, can chew through the plastic material. The primary reason for this behavior is their natural instinct to gnaw, which keeps their teeth sharp and prevents overgrowth. Additionally, attics provide an ideal nesting spot, protected from predators and harsh weather conditions. Squirrels can chew through vents and create entry points, leading to nesting within attic insulation and causing extensive wildlife damage.

The Consequences of Wildlife Damage & Intrusion

Once raccoons or squirrels gain access to your attic, the damage can be extensive. They can tear up insulation for nesting, chew on electrical wires, and leave behind droppings that create health hazards. Furthermore, these animals can bring in parasites and other pests, compounding the problem. The structural integrity of your roof can also be compromised, leading to costly repairs.

Protecting Your Roof Vents From Wildlife Damage

The most effective way to prevent wildlife damage from raccoons and squirrels is to reinforce your plastic roof vents. Installing vent covers specifically designed to withstand wildlife intrusion is a practical solution. These covers are typically made from durable materials such as metal, which raccoons cannot pull off and squirrels cannot chew through.

1. Choose the Right Vent Covers: Opt for metal vent covers that fit securely over your existing vents. Ensure they are specifically designed to prevent wildlife entry.

2. Regular Inspections: Conduct regular inspections of your roof vents to check for signs of tampering or damage. Early detection can prevent larger problems down the line.

3. Seal Other Entry Points: In addition to protecting roof vents, ensure other potential entry points are sealed. This includes gaps around eaves, soffits, and chimneys.

4. Trim Tree Branches: Keep tree branches trimmed away from the roof to reduce access points for raccoons and squirrels.


Plastic roof vents, while functional, are often an easy target for raccoons and squirrels, leading to significant wildlife damage. By understanding how these animals exploit roof vents and taking proactive measures such as installing vent covers, homeowners can protect their attics from costly and hazardous intrusions. Ensuring your roof vents are secure is a small investment that can save you from major headaches and expenses in the future.
