Roof Vents are a very common point of entry and are constructed of various materials such as light weight aluminum (which most people refer to as metal) or plastic.
We often have customers saying “I have the metal roof vents, the animals can’t get through those.” All roof vents, no matter what type, are no obstacle for animals seeking entry into attics.
This picture was taken on a job site where our customer had squirrels inside their attic. The squirrels were very easily able to chew through the metal siding of the roof vent and gain access into the attic.
Squirrels are rodents and are habitual chewers, meaning that their front teeth are always growing and they must continuously chew on anything and everything to grind those teeth down, including metal roof vents!
Raccoons are also able to break open metal roof vents very easily. They are highly intelligent (they can twist handles, open doors and even figure out how to open “animal proof” green bins!) and have very dexterous paws.
Roof vents are no match to both raccoons or squirrels. We highly recommend screening your roof vents to prevent any future wildlife intrusions into your home. It is very important to protect your #1 investment!
