How to Protect Your Roof from Wildlife Damage in Pennsylvania

Wildlife is an essential part of Pennsylvania’s ecosystem, but when animals make their way onto roofs and into attics, they can cause significant structural damage. From squirrels gnawing through shingles to raccoons tearing apart vents, unwanted pests can compromise a home’s roofing system and lead to costly repairs. Taking proactive steps to prevent wildlife intrusions helps protect homes from damage, maintains insulation integrity, and reduces the risk of electrical hazards caused by nesting animals.

Why Do Animals Target Roofs?

Wild animals seek out warm, dry, and safe places for shelter, and a home’s roof and attic provide the perfect environment. Common reasons wildlife may invade a roof include:

• Shelter from predators and weather – Attics and roof cavities offer protection from the elements and predators.

• Easy access through weak spots – Damaged shingles, missing soffits, or loose flashing create entry points for wildlife.

• Food sources nearby – Bird feeders, uncovered trash cans, and tree branches close to the roof attract animals.

Understanding what draws animals to a roof helps in taking the right steps to prevent and deter them effectively.

Common Animals That Cause Roof Damage in Pennsylvania

1. Squirrels

Squirrels are excellent climbers and can easily access roofs via overhanging branches or utility wires. Once on the roof, they:

• Chew through shingles, wood, and vent covers to access the attic.

• Gnaw on electrical wires, increasing fire hazards.

• Build nests in insulation, reducing energy efficiency.

2. Raccoons

Raccoons are strong and highly intelligent. They often:

• Tear off shingles and flashing to enter attics.

• Rummage through garbage, creating additional attraction to homes.

• Damage insulation and structural wood while creating nesting areas.

3. Birds

Birds such as pigeons and starlings seek out gutters, soffits, and vents to build nests. This can result in:

• Blocked ventilation, leading to moisture buildup and mold growth.

• Droppings that corrode roofing materials over time.

• Clogged gutters, preventing proper drainage and increasing the risk of water damage.

4. Bats

Bats can squeeze through gaps as small as half an inch, making them difficult to keep out. While they don’t chew materials, they:

• Leave behind droppings (guano) that pose health risks.

• Cause strong odors in the attic due to urine accumulation.

• Attract other pests like mites and fleas, creating additional problems.

5. Rodents (Mice and Rats)

Small rodents can fit through tiny openings and often enter attics through:

• Gaps in fascia and soffits.

• Holes around roof vents and chimneys.

• Cracks in roofing materials.

Rodents multiply quickly, making early detection and prevention essential.

Signs of Wildlife Damage on a Roof

Detecting wildlife damage early prevents expensive repairs. Signs that animals may be living on or inside a roof include:

• Missing, torn, or lifted shingles.

• Chewed edges around vents, soffits, or flashing.

• Scratching, scurrying, or thumping noises in the attic (especially at night).

• Droppings or strong odors coming from vents or ceilings.

• Nesting materials such as leaves, twigs, and insulation debris near the roofline.

How to Protect a Roof from Wildlife Damage

1. Seal Off Entry Points

Animals often enter attics through gaps, cracks, and weak spots in the roof. Sealing off these areas is the first line of defense.

What to Do:

• Inspect roof vents, chimneys, and soffits for openings and install metal mesh covers.

• Use heavy-duty caulking or foam to fill gaps around the roofline.

• Ensure flashing is securely attached to prevent raccoons and squirrels from prying it open.

2. Trim Overhanging Tree Branches

Tree limbs provide easy access to a roof. Keeping trees trimmed reduces the risk of wildlife intrusion.

What to Do:

• Cut branches at least 6 feet away from the roofline.

• Remove weak or dead limbs to prevent them from falling onto the roof during storms.

• Consider installing metal guards around tree trunks to prevent climbing animals.

3. Install Gutter Guards and Vent Covers

Gutters and roof vents are common entry points for birds, rodents, and other pests.

What to Do:

• Use gutter guards to prevent nesting in downspouts.

• Install durable vent covers to keep animals from squeezing inside.

• Check roof soffits and fascia for signs of chewing or burrowing.

4. Eliminate Attractants

Wildlife is drawn to homes where they can easily find food, water, or nesting materials.

What to Do:

• Move bird feeders away from the house to prevent unwanted guests.

• Secure trash cans with tight lids to avoid raccoon scavenging.

• Regularly clean up fallen fruit, pet food, and other potential food sources from the yard.

5. Schedule Routine Roof Inspections

A professional roofing inspection ensures that small issues don’t turn into costly problems.

What to Do:

• Schedule an annual roof inspection to check for damage or vulnerabilities.

• Repair minor roof issues promptly to prevent animals from taking advantage of weak spots.

• Ensure attic ventilation is working correctly to maintain proper airflow and temperature regulation.
