Case Study: Squirrels Chew Through Drip Edge in Brampton

The following article involves a squirrel removal service in Brampton. This case will detail the steps taken to remove and exclude squirrels from a home in the Madoc community of Brampton- a well-established neighbourhood just west of Hwy. 410 and north of Queen Street.

Brampton: Flower City

Located just north of Mississauga, Brampton is one of the fastest-growing cities in Canada. With a population of nearly 600,000, Brampton is now the ninth most populated city in Canada.

Known for its diversity, the city of Brampton is home one of the largest South Asian communities in the country. It is also home to the Peel Art Gallery and the Rose Theater.

As a growing city, Brampton’s residents are often faced with wildlife control issues. The construction of new neighbourhoods drives squirrels and other animals out of the forest and into the suburbs. Once in the city, the animals adapt and learn to live within attics, garages, and more. Brampton’s vast green spaces and populous neighbourhoods make this city home to many mischievous squirrels.


The property owner contacted us after hearing strange noises from the attic – a strong indication that an animal has found its way inside the space. Concerned that a squirrel may have broken inside the attic, they asked us to inspect and advise.

Hole in Drip Edge Squirrel Entry Point
A hole in the drip edge of the roofs is likely the main point of entry.

Our certified wildlife technician arrived at the property and immediately identified a severe problem with the roof structure. A large stretch of the drip edge had been compromised. Shingles were missing and the wood had been chewed through. This proved to be the main entry point for the squirrels, but as part of our service we inspected the entire roof structure to see if any other potential entry points were present.

Gaps in Drip Edge Brampton
Gaps in the drip edge allow squirrels to easily enter the attic.

Our technician identified several vulnerable roof vents, one of which showed gnawing marks on the corner. Animals are often attracted to roof vents in the winter months because of the heat emitting from them. Because most vents are made of plastic, they can be easily chewed through and become an entry point for the animal.


To allow any squirrels present in the attic to exit in a safe manner, our team installed a one-way-door at the primary point of entry. This feature allows for animals to move through it in one direction only and prevents them from re-entering the attic.

Drip Edge Exclusion Steel Mesh
A one-way-door was removed after a few weeks and re-sealed.

We then proceeded to seal off the drip edge of the roof. For this we used over 10ft. of galvanized steel mesh. This mesh is durable and strong enough to prevent any gnawing.

Next, we covered six roof vents and two plumbing vents to prevent animals from gaining entrance to the attic through other entries.

The homeowner was informed to allow a few weeks for the animals to exit before we return to remove and seal the one-way-door.


Squirrels and other wildlife in residential neighbourhoods are notorious for breaking into homes, particularly attics. The space offers them a warm environment, a nesting site, and protection from predators.

But these creatures can also cause quite the damage by compressing the insulation, reducing its heat retention capacity. Electrical wires can potentially be chewed through, and the presence of urine and feces can make for an awful smell in the home and attract other wildlife to the attic space.

It is important to act fast and contact a professional wildlife removal company to not only remove the animals but also to prevent them from breaking in again.
