Squirrels, raccoons, and birds can do surprising damage to a roof. Learn how animals get in, the harm they cause, and how to keep your roof critter-free.

Your roof is not just exposed to weather. It is also a target for wildlife looking for a warm, protected place to nest. In the Omaha area, squirrels, raccoons, birds, and even bats regularly find their way into roofs and attics, and the damage they cause can be surprisingly expensive. Understanding how animals get in and what draws them there is the first step to keeping your roof secure. This guide covers the most common culprits and how to protect your home.

Why Animals Target Roofs

A roof and attic offer everything a small animal wants: shelter from predators, protection from weather, and a quiet place to raise young. Warmth in the cold months and shade in the hot months make attics especially attractive. Once an animal discovers a way in, it will often return year after year, and others may follow. The key to prevention is eliminating both the access points and the features that make the roof inviting.

Common Entry Points

Animals rarely create a hole from scratch; they exploit weaknesses that already exist. Damaged or loose shingles, gaps at the roof edge where drip edge is missing, uncapped or poorly screened vents, deteriorated soffit and fascia, and openings around the chimney all serve as invitations. Squirrels and raccoons are strong and persistent, and they can enlarge a small gap into a full entry point with alarming speed.

Loose or damaged shingles and flashing.
Unscreened roof, gable, and soffit vents.
Rotted or gapping soffit and fascia boards.
Gaps around the chimney and roof penetrations.
Overhanging tree branches that provide easy access.

The Damage They Cause

Once inside, animals cause damage on multiple fronts. They tear insulation for nesting, chew on wood and even electrical wiring, and leave droppings that create health hazards and odors. On the roof surface itself, they can rip shingles, damage vents, and enlarge openings that then let in water. Birds often clog gutters and vents with nesting material. What starts as a minor pest problem can quickly become a roofing and water-intrusion problem.

Prevention Starts With the Roof

The most effective, humane defense is to make your roof impossible to enter. That means keeping shingles and flashing in good repair, capping and screening all vents, maintaining solid soffit and fascia, and sealing gaps around chimneys and penetrations. Trimming tree branches back from the roof removes the highway animals use to reach it. A well-maintained roof with no easy openings is simply not worth the effort for most wildlife.

Handling an Existing Problem

If animals are already in your attic, the sequence matters. The animals need to be removed humanely first, ideally by a wildlife professional, before any entry points are sealed, so that nothing is trapped inside. Once the attic is clear, the roof repairs and exclusion work can begin: repairing damaged materials, screening vents, and closing every gap so the problem does not recur.

Protecting Your Roof Long Term

Regular roof inspections catch the small vulnerabilities, a lifted shingle, a torn vent screen, a soft spot in the fascia, before wildlife turns them into an entry point. Royalty Roofing can inspect your roof for these weaknesses and make the repairs that keep critters out and water where it belongs.
