Bats In The Attic? How Proper Roof Sealing Can Keep Critters Out This Fall

As the temperature drops and the days grow shorter, humans aren’t the only ones seeking warmth. Critters like bats, squirrels, and even raccoons look for cozy, warm spaces to nest, and your attic might be their prime real estate. One of the most effective ways to prevent uninvited guests is by ensuring your roof is properly sealed. Here’s how proper roof sealing can keep bats and other critters out of your home this fall in the Coulee Region.

Why Do Critters Enter Roofs?

During fall, animals search for shelter from the cold. Your attic provides the perfect environment—warm, dark, and often undisturbed. Bats, in particular, are known for sneaking into small openings in roofs or siding and setting up camp in your attic. Other critters like squirrels and raccoons may also find their way in through gaps in the roofline or fascia.

Once inside, these animals can cause damage by chewing through wires, tearing up insulation, and leaving behind droppings that can lead to health hazards. The key to preventing these invasions is making sure your roof and its components are properly sealed and maintained.

Identify Vulnerable Areas

The first step in keeping critters out is identifying the vulnerable areas of your roof. Common entry points include:

• Gaps in the Fascia: Small animals can easily squeeze through gaps in the fascia, the board that runs along the edge of the roof.
• Holes in the Soffit: The soffit—the underside of your roof’s overhang—can develop cracks or holes that animals can use to enter.
• Loose Shingles or Flashing: Even a single loose shingle or a crack in the flashing around your chimney can be an open invitation for critters.
• Vents and Attic Fans: Unscreened or damaged vents and attic fans provide easy access for animals looking to enter your attic.

How Roof Sealing Helps

Proper roof sealing closes off the tiny gaps and cracks that critters use to gain entry. It’s more than just about keeping water out—sealing your roof also creates a barrier that keeps pests from slipping in through the smallest openings.

• Seal Gaps in Fascia and Soffit: Start by inspecting and sealing any gaps in the fascia and soffit. Applying caulk or sealant to these areas ensures that animals can’t find their way in.
• Inspect Roof Vents: Make sure your vents have screens or mesh to block off entry points while still allowing for proper ventilation.
• Secure Shingles and Flashing: Loose or damaged shingles and flashing should be repaired promptly. This not only prevents animals from entering but also protects your roof from moisture damage.
• Chimney Cap Installation: If you have a chimney, installing a cap with a mesh cover can prevent bats, birds, and other critters from entering through the chimney.

Signs You May Have Bats Or Critters In Your Attic

Before sealing your roof, it’s important to check for signs that critters may already be living in your attic. Look out for:

• Strange Noises: Scratching, rustling, or flapping noises in the walls or ceiling, especially at night, can indicate animal activity.
• Droppings: Bat droppings, or guano, are usually found near walls and are small, pellet-like shapes. If you notice these, you likely have a bat issue.
• Damaged Insulation: Animals often chew through insulation to create nesting spaces. Look for areas where insulation is torn apart or matted down.
• Unpleasant Odors: A strong, musty odor could indicate that animals are nesting in your attic, especially if droppings or urine have accumulated.

Additional Tips For Keeping Critters Out

Beyond sealing your roof, here are some additional tips to ensure your home stays critter-free this fall:

• Trim Tree Branches: Overhanging branches can act as bridges for squirrels and raccoons to reach your roof. Trim back any branches that come within a few feet of your roofline.
• Clean Your Gutters: Clogged gutters can attract animals looking for nesting materials. Regular gutter cleaning can reduce the likelihood of critters making a home near your roof.
• Install Gutter Guards: Gutter guards not only keep leaves out but can also prevent small animals from crawling into your gutters.
• Store Food Properly: Avoid attracting animals by ensuring garbage cans are tightly sealed, and bird feeders are placed away from the home.
