Here is a picture of an installation done by Integrity Wildlife Removal of Groveland FL. As you can see, it looks great and tile removal was not necessary. This is the greatest advantage of Critter Quitters, the vent is repaired and protected without having to pull shingles or tiles. The cost is half what a roofer would require and it looks better. If you are in the Groveland area give Integrity a call for wildlife issues or a Critter Quitter installation quote at 407-675-7006.
