When you think about roof damage, animals may not be the first threat that comes to mind. But according to every seasoned Vancouver roofer, wildlife can be just as destructive as storms—sometimes even worse because the damage goes unnoticed until it’s too late.

Raccoons, squirrels, birds, and rodents are all frequent visitors to rooftops across Metro Vancouver. And while they might look cute from afar, these animals can chew, claw, nest, and contaminate their way through your roofing system. That’s why it’s important to understand the risks—and what steps a professional Vancouver roofer would take to stop them.

Let’s dive into 7 surprising ways animals can damage your roof—and how to prevent it.

1. Chewed or Torn Shingles

Squirrels and raccoons are notorious for chewing through shingles to access attics. Over time, this leads to exposed underlayment, leaks, and serious structural damage. In fact, a local Vancouver roofer might get emergency calls every spring when nesting season begins.

To prevent this, roof contractors often recommend animal-resistant roofing materials like architectural asphalt shingles or reinforced synthetic underlayment. A reputable Vancouver roofer will also check for bite marks, torn edges, or lifted shingles during inspections.

2. Blocked Vents and Clogged Gutters

Birds love to build nests in roof vents and gutters, especially in Vancouver’s leafy neighborhoods. But these blockages can lead to water pooling, mold, and even interior flooding. According to Natural Resources Canada, roofs with poor ventilation are more prone to moisture buildup and heat retention, which can lead to long-term damage in both the attic and roofing materials.

A reliable Vancouver roofer can install mesh vent covers and recommend gutter guards to keep birds out. Many roof companies also offer seasonal cleaning and inspection services to catch these issues early.

3. Scratched or Uplifted Flashing

Animals seeking warmth or shelter may try to lift flashing around chimneys or skylights. This loosens seals and allows rainwater to seep in.

An experienced Vancouver roofer knows this is one of the first things to inspect after an animal sighting. A good roof company in Vancouver will reseal or replace damaged flashing and reinforce it to prevent repeat invasions.

4. Animal Droppings and Debris Buildup

Bird droppings and nesting materials may seem minor, but they’re acidic and can corrode shingles, stain metals, and attract more pests. According to the Canada Mortgage and Housing Corporation (CMHC), regular roof maintenance is essential to prevent moisture issues—especially those caused by organic debris like leaves and droppings, which can gradually compromise the roof’s integrity.

If you notice discoloration or clumps of leaves, a qualified Vancouver roofer can help clean and sanitize your roof safely. Some roof contractors also suggest regular drone inspections to monitor problem areas without needing full climbs.

5. Chewed Wires on Rooftop Units

It’s not just your shingles at risk. Rodents can chew wires on rooftop HVAC units or solar panels, which may lead to outages or even electrical fires.

That’s why a proactive Vancouver roofer works closely with HVAC and solar professionals to install protective guards and coverings. It’s a service many rooftop roofing companies in Vancouver now include as part of their maintenance plans.

6. Entry into Attics Through Weak Spots

If there’s a small hole in your soffit or roofline, chances are a raccoon will find it. Once inside your attic, they can destroy insulation, chew wood, and even raise a family—multiplying the damage.

One experienced Vancouver roofer noted that animal entries spike in colder months, especially in areas like Burnaby and North Vancouver. He recommends sealing potential entry points with metal mesh and booking biannual inspections with a trusted roof company in Vancouver.

7. Noise, Stress, and Hidden Health Risks

Animal activity doesn’t just damage your roof—it affects your peace of mind. Scratching, thumping, and chirping noises can disrupt sleep and add anxiety to your daily life.

Worse, raccoons, birds, and rodents carry diseases. A certified Vancouver roofer will not only assess physical damage but may also coordinate with pest control to ensure the problem is fully addressed. Top roof companies in Vancouver emphasize safety as much as structure.

What a Vancouver Roofer Recommends to Keep Animals Away

A reliable Vancouver roofer doesn’t just fix leaks and replace shingles—they help you take proactive steps to avoid bigger issues down the line. When it comes to animals on your roof, prevention is always better (and cheaper) than repair. Here’s what most experts strongly recommend:

  • Trim trees that provide roof access
    Overhanging branches act like bridges for squirrels, raccoons, and even rats. A professional Vancouver roofer will often point out tree limbs during inspections and suggest safe trimming to prevent easy access to your rooftop.
  • Install vent and chimney guards
    Birds and small mammals love to sneak into open vents and chimneys. Guards and mesh screens can keep critters out without blocking airflow or creating a fire hazard. Most roof contractors can install these protective barriers quickly and affordably.
  • Seal eaves, soffits, and roofline gaps
    Even small gaps along the roof’s edge can be enough for a determined raccoon or squirrel to squeeze through. A skilled roof company in Vancouver will inspect for signs of wear or entry points and seal them with rodent-resistant materials.
  • Schedule spring and fall roof inspections
    These two seasons are the most active for animal nesting and roof damage. Booking regular inspections with a trusted Vancouver roofer allows for early detection and prevention of potential animal-related issues before they escalate.
  • Work with reputable roof contractors who understand wildlife risks
    Not all roofers specialize in wildlife prevention. Choose a rooftop roofing company that has experience with animal-proofing and understands how local wildlife behaves—especially in Vancouver’s urban and wooded neighborhoods.

Partnering with an experienced Vancouver roofer ensures your home is protected not just from rain and snow—but also from the raccoons, squirrels, and birds quietly turning your roof into their next hideout. With expert help, you can keep your roofing system strong, secure, and pest-free year-round.

Conclusion

Animals may be silent invaders, but their damage is anything but small. From chewed wires to attic infestations, the harm they cause can cost thousands in repairs—and lead to dangerous conditions.
