Roof-Soffit Intersection Entry Point
Soffits are vulnerable to break-ins, especially where they meet the roof below. Squirrels can chew right through them and raccoons will break them to reach the attic inside.

Initial Measures

The technician found the main entranceway which was an opening at the intersection of a soffit, this was the entryway the squirrel used to enter the attic. A squirrel, that was likely the occupant, was present at the entryway during the inspection. The one-way door was applied at this point to assure the removal of the squirrel from the attic.


The technician used a one-way door and attached it with galvanized steel mesh to the soffit intersection the animal was using to enter the attic. The one-way door was successful and the animal vacated the attic through the one-way door and left the property and the sounds in the attic stopped.

While the customer did not know the location of the entryway the entry was discovered by the technician after a full roof inspection. The one-way door was attached to the open soffit intersection. The squirrel vacated through the one-way door and the technician returned to take the door down and was informed by the customers that the sound had stopped.
