If you live in the Denver metro area, especially in Littleton, your roof does more than protect you from snow, sun, and hail—it also keeps out some very determined and destructive wildlife. From squirrels and raccoons to birds and even the occasional bat, critters can cause serious roof damage that leads to costly repairs if not addressed quickly.
At Anderson Builders, we’ve helped countless homeowners across Littleton and the Denver area repair roof damage caused by animals and prevent it from happening again.
Common Animals That Damage Roofs in the Denver Area
Colorado’s changing seasons and suburban landscapes create the perfect environment for wildlife to seek shelter in your home—especially your roof.

- Squirrels
Squirrels are one of the biggest culprits when it comes to roof damage in Littleton and surrounding areas. They can:
- Chew through shingles, wood, and vents
- Create entry holes into attics
- Damage insulation and wiring once inside

- Raccoons
Raccoons are strong and persistent. They often:
- Tear up shingles and roof decking
- Pry open soffits or fascia boards
- Create large entry points into attics

- Birds
Birds may seem harmless, but birds like woodpeckers and Norther flickers can cause serious damage:
- Peck holes into wood siding and roofing materials
- Nest in vents, gutters, and chimneys
- Block proper roof ventilation
- Bats
Bats can enter through very small gaps in your roofline and attic:
- Leave behind droppings (guano) that damage materials and create health risks
- Often go unnoticed until the infestation grows

- Mice and Rats
Rodents can squeeze into tiny openings:
- Chew through roofing materials and insulation
- Multiply quickly, worsening damage over time

Signs You May Have Animal Damage on Your Roof
Not all roof damage is immediately visible from the ground. Here are some key warning signs Denver homeowners should watch for:
- Scratching, scurrying, or movement sounds in the attic
- Missing, curled, or damaged shingles
- Small holes or gaps near vents, eaves, or roof edges
- Droppings or nesting materials in gutters or around your home
- Water leaks or stains on ceilings
If you notice any of these signs, it’s important to act quickly before minor damage turns into a major repair.

Why Animal Roof Damage Is a Serious Roofing Issue
Critter damage isn’t just a nuisance—it can lead to significant problems, including:
- Roof leaks and water damage
- Mold growth in attic spaces
- Structural wood rot
- Increased energy bills due to poor insulation
- Fire hazards from chewed electrical wiring
In Colorado’s climate, even small openings can allow snow and moisture to enter your home, making fast repairs essential.

Roof Damage – How to Prevent Animal Roof Damage
Preventative maintenance can save you thousands in repairs. Here are some effective steps:
- Schedule regular roof inspections (especially after storms or winter)
- Trim tree branches away from your roofline
- Install critter-resistant vent covers
