Attic ventilation is designed to allow fresh air to circulate under your roof, helping to:
Most homes achieve attic ventilation through a combination of:
However, each of these vents can be exploited by nuisance wildlife—leading to costly damage.
Nuisance animals are opportunists, always looking for a way to get inside a warm, safe space—and attic vents are an easy target. Here’s how different animals take advantage of attic ventilation systems:
🐿 Squirrels – Chew through plastic vents, tear apart screens, and squeeze through gaps as small as 1.5 inches.
🦝 Raccoons – Use their strength to pry open weak vent covers, especially plastic or aluminum screens.
🦇 Bats – Can fit through openings as small as ⅜ of an inch, making gable vents a common access point.
🐦 Birds – Nest inside roof vents and soffit vents, blocking airflow and creating a mess.
🐀 Rodents – Use small openings in soffit vents to gain access to insulation, leading to infestations.
Once inside, these animals can damage insulation, chew on electrical wiring, and leave behind hazardous waste, leading to costly repairs.
Many homeowners resort to makeshift solutions like wire mesh or foam sealants to block animal access—but these methods often reduce airflow, leading to poor ventilation and potential roof damage.
The best solution is to install HY-GUARD EXCLUSION wildlife-proof vent covers. These covers allow for full attic ventilation while ensuring no animals can get inside.
