Your roof can be a tempting target for curious critters. Squirrels, raccoons, birds, and even insects often look to rooftops for shelter, warmth, and nesting spots. Unfortunately, their presence can cause serious damage—leading to leaks, structural issues, and expensive repairs if left unchecked.

One of the most common entry points for wildlife is through small gaps or weak spots in sloped or flat roofs. Animals can chew through shingles, soffits, or fascia boards to gain access to your attic. Birds may nest in vents or chimneys, and rodents often squeeze through openings no bigger than a quarter. Once inside, they can damage insulation, wiring, and even your HVAC system.

To prevent this, regular roof inspections are essential. Look for signs of wear and tear, loose shingles, or small holes that could be exploited by animals. Installing a chimney cap and covering vents with durable mesh screens can block some of the most common entry points. Trimming back branches that hang over the roof can also help.

Gutters should also be kept clear. Clogged gutters can trap moisture, attracting insects and creating soft spots along the roofline that animals can exploit. Clean, functioning gutters discourage nesting and reduce overall risk.

In areas where wildlife is especially active, some homeowners choose to install deterrents like ultrasonic devices or motion-activated lights to make their homes less inviting. But the most effective solution is often just maintenance—sealing gaps, replacing damaged shingles, and keeping the roof in good condition year-round.

Wildlife may be part of nature, but it doesn’t belong in your attic, regardless of the type of roof material or whether it’s sloped or flat. The professionals at Northern Illinois Seamless Roofing provide inspections and repairs to help keep critters from accessing your attic.
