How to protect your roof from animals

Squirrels, raccoons, birds, or rodents can cause serious damage to your roof if they find an entry point.
Fortunately, there are several effective ways to protect your roof from nuisance animals and avoid costly repairs.

Why do animals target your roof?

Your roof, especially when it has entry points like holes or damaged soffits, offers the perfect shelter for many species. These intruders may be looking to build a nest, stay warm, or hide from predators. Once settled in, they can:

Damage roofing materials by gnawing on them
Clog gutters with branches and nesting debris
Move or break shingles
Leave droppings, causing odors and health risks
Create water infiltrations by weakening the structure

1. Perform regular roof inspections

Prevention starts with regularly monitoring the condition of your roof. It’s recommended to inspect it at least twice a year — ideally in spring and fall. These inspections help detect early signs of:

Gnawing or punctures
Nests in soffits or gutters
Displaced or damaged shingles
Holes around vents or chimneys

If you spot the beginnings of an infestation, act quickly to limit the damage.

2. Trim overhanging tree branches

Tree branches too close to your roof act as natural bridges for animals. By trimming them, you reduce access to your roof.

Make sure branches are at least one meter (3 feet) away from the roof to prevent raccoons and squirrels from climbing up easily.

3. Repair cracks, holes, and damaged soffits

Even the smallest openings are an invitation for rodents, which can squeeze through spaces as small as a coin. Check:

Around chimneys
Ventilation joints
Soffits and fascias
Roof edges

Call a roofer to seal the gaps and restore your roof’s waterproofing. At Duro-Toit, our team can step in quickly to secure your roof in emergency situations.

4. Clean your gutters

Clogged gutters are not only a water drainage issue — they’re also the perfect refuge for birds and small mammals. A thorough gutter cleaning in the fall helps:

Prevent nest building
Ensure proper drainage
Avoid water accumulation and roof deterioration

We recommend annual maintenance, especially before winter.

5. Install deterrent devices

Some mechanical solutions can effectively keep animals from settling on your roof:

Bird spikes: effective against pigeons and other birds
Protective netting: ideal for hard-to-reach areas
Reinforced vent screens: block attic access
Natural repellents: peppermint oil, cayenne pepper, or white vinegar can discourage certain animals

These deterrents should be professionally installed to remain effective without damaging your roof.

Extra tips: Animal on your roof at night?

If you hear scratching, thumping, or scurrying above you after dark, you’re likely wondering: What animal would be on my roof at night? Common nighttime roof invaders include:

Raccoons – active at night and excellent climbers
Squirrels – though diurnal, some may still cause noise in the early evening or dawn
Rodents – such as rats or mice looking for warmth

How to get rid of animals on roof?

Inspect the attic or crawl space to locate the intruder
Use humane traps or call a professional for animal in roof removal
Seal all access points once the animal is removed
Avoid DIY removal at night, especially with larger animals like raccoons

If you’re unsure what kind of animal is making noise, it’s best to consult a pest control or roofing professional — especially for safe and effective animal on roof removal.
