Job Overview

Location: Old Toronto, Ontario
Structure: Three-storey detached house with flat roof
Problem: Squirrel activity reported in third-storey ceiling/attic area
Service: Humane squirrel removal and exterior exclusion
Visits: Three visits

Summary

Our team addressed reported squirrel activity in the upper attic area of a three-storey detached home in Old Toronto. The work was completed over three visits and included humane eviction using a one-way door, followed by permanent sealing of the entry point and later installation of extended roofline exclusion. No further activity was reported after completion.

Background / Property Context

The property is a tall, three-storey detached house with a flat roof and multiple roofline features, including chimneys and drip edges. The height and roof configuration required multiple technicians to safely access and service the upper roof areas.

Customer Concern

The homeowner reported hearing movement and scratching sounds in the ceiling near the third-storey roof, primarily during early morning hours. The timing and location of the noise were consistent with squirrel activity.

Inspection & Findings

During the initial inspection, our technicians identified an opening near the roofline where two chimney structures meet. Additional gaps were observed along the drip edge and soffit areas that could allow wildlife access.

Photos from the site show:

• Open soil and disturbed areas near the foundation and deck supports
• A one-way wildlife door installed at the roof drip edge
• Gaps along siding and soffit junctions
• Roof-level access points visible from above

 

 

 

Cause Analysis

Squirrels commonly exploit elevated roofline gaps, especially near chimneys and drip edges, to access attic spaces. On taller homes, these areas are less visible from the ground and may go unnoticed until noise is heard indoors. The flat roof and intersecting structures created sheltered entry points suitable for denning.

Treatment / Removal

On the first visit, our team installed a one-way door at the primary roofline entry point to allow the squirrel to exit without re-entry. The work was completed humanely and without trapping. Additional exclusion was recommended at that time to address nearby vulnerable areas.

Exclusion & Repairs

On the second visit, after the homeowner confirmed that no further activity was heard, the one-way door was removed and the original entry point was sealed.

Several months later, during a separate wildlife service at the same property, the homeowner approved the previously recommended preventative work. Approximately 30 feet of drip edge exclusion was installed using galvanized steel mesh to reinforce the roofline and prevent future access.

Outcome & Confirmation

Following removal of the one-way door and sealing of the entry point, no additional squirrel activity was reported. After the extended drip edge exclusion was completed, the roofline was reinspected and confirmed secure, with no signs of ongoing or renewed wildlife entry.

Technician Notes

The initial and follow-up visits were completed by our wildlife team, with Ardian acting as lead technician on site. Due to the height of the structure and roof access requirements, multiple technicians were present to complete the work safely and effectively. All wildlife activity was resolved using non-lethal, exclusion-based methods.
