Bats getting into the attic roof vents of this grand blanc home. Ridge vents are a common access point for bat colonies to enter your homes attic space. Over time ridge vents begin to warp and separate from your shingles, this open space gives way to bat infestation or other wildlife pests. We repair roof vents to secure and seal them to the roof to prevent lifting and keep bats and pests out. Our one way exclusion doors remove the bat colony safely and keeps them from returning.
