If you live in an area with trees close to your house, every once in a while, you’re going to hear little feet running across your roof. Most of the time it’s squirrels, though on occasion it can be rats, mice, even raccoons. In some cases, this noise can be a sign of a pest infestation, which is why it’s important to call a pest control company.
But, for many, the bigger concern is the roof. Are the animals on top of your home causing issues?
Animal Activity and Roof Longevity
The good news is that roofing was made to handle impact, even though it may appear thin on the surface. People are supposed to be able to walk on a roof without damaging it, especially if it was properly installed.
Still, frequent wildlife on a roof can cause issues. Wildlife walking or running across a roof is not uncommon, but the effect that activity has on the roof depends on several factors, including the species involved, the roofing material, and how often the animals visit.
In general, a few light-footed squirrels or birds will not cause noticeable damage to a modern, well-maintained roof. However, frequent activity, nesting behavior, or heavier animals can start to wear down protective surfaces or compromise roofing components over time.
Common Forms of Animal-Related Roof Damage
When wildlife does create damage, it typically falls into one or more of the following categories:
- Shingle Damage – Animals with sharp claws, such as squirrels and raccoons, can tear, lift, or dislodge shingles, exposing the underlayment and increasing the risk of leaks.
- Vent and Soffit Entry – Persistent animals may attempt to chew or claw through roof vents, fascia, or soffits in an effort to reach attic spaces for nesting.
- Gutter Obstruction – Nesting material and debris left behind by birds or rodents can block drainage paths, leading to water pooling and eventual roof deterioration.
- Insulation Disturbance – If animals find their way into the attic through small openings, they can compress or displace insulation, reducing energy efficiency and sometimes contaminating the area with waste.
Occasional noise on the roof does not always indicate damage, but consistent scratching, thumping, or chewing sounds – especially during the night – should be taken seriously. This activity often points to an attempt to enter or establish a nesting site, which can escalate structural and pest problems quickly.
Preventing Roof Damage from Wildlife
Homeowners can minimize animal-related roof issues with proactive maintenance. Trim back overhanging branches that provide easy roof access, ensure attic vents and soffits are screened with heavy-gauge mesh, and inspect for small gaps around eaves and flashing.
If activity persists or you suspect nesting, it is best to contact both a pest control professional and a roofing specialist to assess and address the problem safely.
