Case Study: Squirrels Break Through Soffits in East York

This case study details a squirrel removal job in East York. The initial call to the property was for a squirrel that was tearing down the soffiting and chewing the drip edge, creating a visible entry point, and may have entered the attic. A technician was dispatched to inspect and remove the animal via a one way door. Consistent activity in the attic was heard for an extended period.

EAST YORK, Toronto

In 1791 East York was named The Dublin Township, however, like all things Irish it was replaced with the name of a British royal. Governor John Simco for who the Simco area is named changed it to East York to please the Duke of York. This has been its name since. East York was initially the place of the industry for York, what the city was once called. There were many wealthy families like the Skinners, the Helliwell’s and the Taylors who opened wood and paper mills as well as York’s first brewery and distillery along the don valley river. This made East York a very wealthy township and it has not changed since that time.

Exterior Inspection

The initial inspection of the home revealed severe damage to multiple areas of the drip edge. The squirrel had successfully entered the attic and a one-way door would be necessary to remove it. The technician also noticed several other areas such as roof vents and soffit intersections that could be possible entryways for wild animals.

Severe Squirrel Damage on Roof
The squirrel’s entry point was found in a corner of the roof where insulation and debris covered the shingles.
Roof-Soffit Intersection Squirrel Entry Point
The intersections where the soffits meet the roof below are vulnerable to squirrel and raccoon break-ins. Animals can push or chew their way through the soffit while standing on the roof.

Initial Measures

The initial measures taken by the technician included the installation of a one-way door to allow the animal to humanely vacate the attic while preventing it from re-entering. This process can take three to ten days. The technician also excluded several possible entryways on the roof. The main problem area was roof vents and soffit intersection with the roof. Both can be accessed very easily by rodents, like squirrels and wild animals. The reason for further exclusion, or the sealing of holes, is to prevent both the animal in the attic from accessing other areas to make a new entryway but to act as a barrier to future wild animal ingress. It’s a shield against wildlife. A wildlife shield. The technician also deodorized the entryway due to strong animal ordure.

Squirrel One Way Door on Roof
The one-way door is a very effective method of squirrel removal. It lets the animals leave on their own, without hurting anybody.

Proposed Exclusion

The proposed exclusion by the technician was extensive. Four roof vents were protected using back rubber coated galvanized steel cages which are extremely strong and long-lasting. They are bolted to the roof over accessible roof vents that could allow an animal, like a squirrel to easily enter the attic. A plumbing vent was used to allow modern plumbing in older homes that did not have the proper plumbing initially. This vent was covered with a rubber-coated galvanized steel mesh cage and bolted to the wall like the roof vents. The roof edge of a house is always the first area to warp in harsh weather. It is important to get it repaired or excluded quickly as it is open access to many different kinds of animals and rodents. Sealing off these areas with flashing or steel mesh can save you thousands in roof repairs. The roof soffit intersection is a part of the roof that is, perhaps the most delicate and easy to access point on your whole house. It is not connected in any way, the soffit and the roof have a gap between them that a raccoon can lift and bend with its bare hands. Squirrels will often chew an opening as they are rodents with incisors that keep growing throughout their lives there main method of gaining ingress into your attic is through the act of chewing.

Roof-Soffit Intersection Exclusion
Our technicians always replace the one-way door with mesh to avoid another invasion. Squirrels will often come right back, so it is best to block this area off.
Roof Edge Exclusion
Pest-proofing the gaps in the roof would keep squirrels and other animals out for years to come.


In conclusion, the squirrel was evicted from the attic and the one-way door was removed from the drip edge which was then fully excluded. The house was effectively protected from rodent and wildlife infestation or occupation, respectively, and the customers were pleased with the results.
