Washington Roofline Repair

Wildlife Exclusion for Washington Homeowners — Raccoons, Squirrels & Birds in Your Roofline

Washington's dense urban wildlife population treats your roofline as premium real estate. Raccoons pull back weakened soffit panels. Squirrels chew through gaps within hours of them opening. Starlings and bats colonize any eave opening they find. We seal every entry point permanently and repair the structural damage they leave behind.

Wildlife exclusion work on Washington home — sealing animal entry points in soffit panels

What We Do

Wildlife Exclusion Is Not Pest Control

Wildlife exclusion focuses on permanently sealing and repairing the structural gaps in your roofline that allow animals to enter. The work is structural — replacing chewed or rotted soffit panels, sealing corner returns with galvanized mesh, installing metal drip edge at vulnerable transitions, and eliminating every gap in the eave system that an animal could use as an access point. No trapping. No chemicals. No extermination. Just a sealed, repaired roofline that denies access permanently.

This is different from what a pest control company does. Pest control treats infestations with chemicals or traps. Wildlife exclusion addresses the building itself — closing the structural openings that make your home vulnerable in the first place. For roofline wildlife problems in Washington, exclusion is both the more humane and the more permanent solution.

Washington's Common Roofline Wildlife

Washington supports a dense urban wildlife population across both sides of the Cascades. These are the species that most commonly exploit roofline gaps:

Raccoons — the most structurally damaging species in Washington; strong enough to pry back softened soffit panels and physically enlarge gaps; most active from late winter through spring when females are seeking denning sites
Gray squirrels — year-round nesters in western Washington; can fit through a gap the diameter of a quarter and will chew existing small gaps larger; primarily enter at corner returns and gable vents
European starlings and house sparrows — cavity nesters that colonize any gap larger than 1.5 inches; nesting material creates fire hazards and their feces cause significant structural damage when colonies establish
Little brown bats and big brown bats — can enter through a gap as small as 3/8 inch; Washington bat colonies roost in attic and eave cavities from spring through early fall; exclusion must be timed carefully around pupping season (June–July)
Virginia opossums — increasingly common in western Washington; will use existing openings large enough for raccoons; primarily active November through March

Why All Entry Points Must Be Sealed in One Visit

A common mistake is addressing only the visible entry point — the hole you can see, the panel that's obviously chewed. Wildlife exclusion only works when every gap in the roofline system is closed in a single comprehensive visit.

Raccoons and squirrels don't have a single point of entry. They've typically identified multiple access options. When you close one gap without closing the others, the animals simply shift to the next opening. In some cases, sealing the primary entry without addressing secondary gaps actually traps animals inside, which creates a more serious problem.

Effective exclusion means the contractor goes up a ladder and inspects the entire eave perimeter — every corner return, every soffit-to-fascia junction, every gable vent, and every point where utilities enter the structure. Everything gets closed, everything gets checked.

Wildlife Exclusion Cost Ranges in Washington

Job Type	Typical Range (Washington)
Entry point sealing only (1–3 gaps, mesh)	$250–$600
Full perimeter exclusion sealing	$600–$1,500
Add: soffit panel replacement (animal damage)	+ $200–$700
Add: fascia repair at entry points	+ $300–$800

Frequently Asked Questions

What's the difference between wildlife exclusion and pest control?

Pest control companies use chemicals, traps, and extermination. Wildlife exclusion is structural work — we repair and seal the physical gaps in your home that allow animals to enter. The materials are galvanized mesh, aluminum flashing, caulk, and replacement structural panels. The result is a roofline that animals physically cannot access, rather than one where they're managed chemically or removed and allowed to return through the same opening.

How do I know if it's raccoons vs. squirrels vs. birds?

The sounds and timing help: raccoons are louder and heavier, most active at dusk and dawn, and cause larger physical damage when they enter. Squirrels are lighter and faster-moving, typically active during daylight, and you'll often hear them entering and exiting in early morning. Birds (starlings, sparrows) are active during daylight hours and create a distinctive chattering. Bats exit at dusk in a stream and are silent inside the structure. The inspector will look for physical evidence at the entry points — tooth marks vs. prying damage vs. nesting material — to identify what you're dealing with.

Is there a bad time of year to do wildlife exclusion?

For bat exclusion specifically, work should not be done during June and July in Washington — that's when bat pups are flightless and sealing them inside creates a serious problem. For other species, exclusion can be done year-round, though winter (December–February) is generally the best time because most wildlife activity is lower and animals are less likely to be actively nesting. The inspector will advise on timing based on what species you have and the season.

After exclusion is done, will the animals try to get back in?

Raccoons and squirrels with established territory will probe the roofline for new entry points after their old one is sealed. This is why the full perimeter seal approach is critical — if there's another gap anywhere, they'll find it. When the job is done correctly, all gaps are closed with materials the animals can't breach (galvanized mesh, solid metal flashing), and persistent attempts to re-enter typically stop within a few weeks as the animals establish new territory.
