Holiday Hazards: Animal Damage & Roof Leaks After Snowstorms

AAA Roofmasters • January 13, 2026

The holiday season brings festive cheer, sparkling lights, and cozy nights indoors. But for homeowners in the Greater Toronto Area, it’s also a time to be vigilant about your roof’s condition—especially after heavy snowstorms. At AAA Roofmasters, we know wintery weather can leave your home vulnerable to two major hazards: animal damage and roof leaks. Understanding these risks and how to address them can save you costly repairs and help keep your home safe and dry all winter long.


How Snowstorms Create Opportunities for Animal Damage


When snow blankets your roof, local wildlife—such as squirrels, raccoons, and birds—seek warmth and shelter. Eaves, attics, and under-roof spaces become prime real estate for these animals. Snow and ice can block their usual food sources, prompting them to look for easy access to your home. Unfortunately, they are skilled at finding weak points along your roofline, soffits, vents, and chimneys.


Animals may chew through roof shingles, gnaw on woodwork or insulation, and create new entry points. Once inside, they can cause further damage by nesting, bringing in debris, and even chewing on electrical wiring, which can become a fire risk if left unchecked. Animal infestations are not just a nuisance—they can quickly escalate into a significant problem for your roof’s integrity and your family’s safety.


Common Signs of Animal Damage on Your Roof


After a snowstorm, be on the lookout for these warning signs:


  • Scratching or scurrying noises from the attic or roof cavity, especially at night
  • Visible entry holes or gnawed patches on eaves, soffits, or roof vents
  • Damaged or missing shingles around roof edges
  • Droppings or nesting material in the attic
  • Disturbed insulation or chewed wires


If you notice any of these, it’s time to act quickly. AAA Roofmasters provides emergency roof repair services throughout Mississauga, Etobicoke, Toronto, Oakville, and across the GTA to secure entry points and prevent further animal access.


How Snowstorms Lead to Roof Leaks


Heavy snowfall, followed by thaw cycles and more precipitation, can put any roof system to the test. When snow melts, water can find its way into small cracks, under damaged shingles, or through vulnerable flashing. This risk is even greater if an animal has already created holes or gaps. Once water infiltrates your roof, it can cause stains, mold growth, insulation damage, and even compromise your home’s structural integrity.


Roofs that are older, haven’t been inspected recently, or have existing minor issues are most at risk. Even newly installed roofs can develop leaks if wildlife has managed to breach their protective layers.


How to Check for Roof Leaks After a Snowstorm


After severe winter weather, do a careful inspection inside and outside your home:


  • Look for water stains or discoloration on ceilings and walls
  • Check your attic for dampness, musty odors, or visible drips
  • Inspect the underside of your roof deck for wet spots or mold
  • From ground level, look for missing, buckled, or shifted shingles, particularly at roof edges and around chimneys and vents


If you see any of these signs, contact AAA Roofmasters right away. We provide fast, professional leak detection and emergency repairs to stop water damage in its tracks.


Preventative Tips to Avoid Animal Damage & Roof Leaks


Prevention is the best defense against winter roof hazards. Here’s what you can do:


  • Schedule annual professional roof and attic inspections with AAA Roofmasters to catch vulnerabilities before animals do
  • Trim tree branches away from your roof to make access more difficult for wildlife
  • Repair or replace any damaged or loose shingles, soffits, vents, or flashing before winter sets in
  • Install wire mesh over vents and chimney openings to block animal entry—but never block airflow
  • Keep your attic well-ventilated and insulated to minimize snow melt and ice damming
