Squirrels have become quite reliant on humans to survive. In other words, they’ve become quite a common pest. You may notice them in your yard or getting into your garbage. It can be intriguing to watch them with their bouncy gallop and their big bushy tail as they cross the yard. But then, suddenly, they’re on your roof, hopping along like it’s theirs. This is where things get messy. Once they have access to your roof, they’ll likely cause loads of costly damage. Being excellent chewers, they have a good chance of ending up inside your home and extending the damage even further.
