This homeowner made the right call to deal with their wildlife intrusion now rather than pushing the problem off and waiting until Spring. It is our experience that all wildlife problems should be dealt with quickly to prevent the animals and the elements from doing further damage to your home.
Animals often will tear through shingles and plywood to gain access into the attic. This often results in snow and water making its way into the attic space, potentially causing water damage and mold issues to the insulation and drywall. As you can see in this photo, there is a pile of snow inside the attic already, which will end up melting and could lead to problems for this homeowner if left unsolved.
