Squirrels, Raccoons, and Rats in the Attic: How Animals Get Through East Texas Roofs
The first cool front of the fall usually reaches Tyler sometime in October. Within a week or two, the phone calls change. Instead of hail bruising and heat-cracked shingles, homeowners start describing scratching above the bedroom ceiling at dusk, a thump across the attic in the middle of the night, or the smell that comes from somewhere above the hall closet.
Squirrels, raccoons, rats, and the occasional opossum are doing what they do every year in East Texas: looking for a dry, warm place to spend the winter. An attic over a heated house, with insulation to burrow into and a roof that has a soft spot somewhere, is as good as it gets. Understanding how they get in is the first step to keeping them out, and most of the entry points are roofing problems before they are wildlife problems.
Why fall is the season for it
Animals in East Texas do not hibernate, but they do nest. Fox squirrels and gray squirrels have a second litter in late summer, and by October those young are looking for territory of their own. Raccoons start scouting den sites as the nights drop into the 40s. Roof rats, which are common throughout Smith County, move indoors as outdoor food sources thin out and temperatures fall.
The timing matters because a hole that an animal opens in October becomes a water problem by the first long winter rain in December or January. Fall is the window to find the opening while the fix is still a repair on the eave rather than a rotted section of decking.
Where they get in
Nearly every animal entry we find is at one of a handful of places. Most of them are spots a homeowner can check from the ground with a pair of binoculars.
The eave and fascia line
The eave is the most common entry point by a wide margin. Where the roof deck meets the fascia board, there is often a small gap, especially on older homes in Tyler, Lindale, and Whitehouse where the original drip edge was never installed or the fascia has pulled away. A squirrel only needs an opening about the size of a golf ball. A rat needs less. Once the gap exists, chewing widens it, and the fascia behind it is usually soft from years of gutter overflow and pine needle load, which makes the work easy.
Soffit vents and loose soffit panels
Soffit vents are supposed to be screened, but the screen on older vents is often thin aluminum or plastic that has corroded or cracked. Vinyl and aluminum soffit panels also pop loose at the corners, particularly after high wind, and a raccoon will push a loose panel up and climb straight into the attic.
Gable vents and roof vents
Gable end vents on houses in Jacksonville, Henderson, and across the older neighborhoods of Tyler are frequently fitted with nothing more than window screen. Raccoons tear it. Squirrels chew through it. Turbine and box vents on the roof surface have the same problem, and a turbine with a missing cap is an open door.
The ridge
Ridge vent is excellent for attic airflow, but if the end caps are missing or the vent was installed without a closure strip, rats and squirrels will work their way in at the gap between the shingles and the vent. We also find ridge caps lifted by wind that leave just enough room underneath.
Plumbing boots and other penetrations
The rubber collar on a plumbing vent boot cracks and splits after enough summers of Texas sun. Squirrels chew the softened rubber, and the resulting hole is big enough for a rat to drop straight down the outside of the pipe. This is the same failure that causes some of the most common slow leaks we repair, which is covered in more depth in our post on flashing failures on Tyler roofs.
Roof to wall corners
Where a porch roof or garage roof meets the main wall of the house, the shingles and the siding often leave a small triangular gap at the bottom of the step flashing. Animals find it. So does water.
The damage they leave behind
The animal itself is only part of the problem. What it does once inside tends to be the expensive part.
- Chewed wiring. Squirrels and rats gnaw constantly to keep their teeth worn down, and attic wiring is a favorite target. This is a fire risk, not just a nuisance.
- Contaminated insulation. Urine and droppings soak into blown-in insulation. Once it is wet it loses its insulating value, and a heavy infestation often means pulling and replacing it.
- Blocked ventilation. Nests built in soffit bays and against vents stop the attic from breathing. In East Texas that traps summer heat and winter moisture, both of which shorten the life of the shingles above. Our post on summer heat damage explains why attic airflow matters so much here.
- Water intrusion. Every entry hole is also a leak path. A raccoon that peels back a section of soffit or shingles has created an opening that the next rain will use.
- Structural rot. Fascia, soffit, and decking that have been chewed and then soaked rot quickly in our humidity.
What to do when you hear something in the attic
Resist the urge to climb up and seal the hole you found right away. If an animal is inside and you close its exit, it will chew a new one, often somewhere worse. A raccoon with young in the attic will tear through drywall to get back to them.
The order that works is straightforward:
- Confirm what you are dealing with. Scratching at dawn and dusk usually means squirrels. Heavy thumping at night points to a raccoon. Light, fast scurrying after dark, often inside the walls as well as the attic, is typical of roof rats.
- Get the animal out. A licensed wildlife control operator handles removal, including one-way exclusion doors that let the animal leave but not return. This is not something a roofing contractor does, and it is not something we would advise a homeowner to attempt with a raccoon.
- Have the roof inspected for every entry point, not just the one you noticed. Animals rarely use a single opening. A thorough roof inspection covers the full eave line, every vent, the ridge, every penetration, and the roof to wall transitions.
- Repair the openings permanently. Expanding foam and a piece of hardware cloth stapled over a hole is a temporary measure, and squirrels treat foam as a chew toy. Permanent repair means replacing chewed or rotted fascia and soffit, fitting vents with heavy gauge galvanized or stainless screen, installing proper drip edge, adding closure strips under ridge vent, and replacing split boots.
- Deal with the attic. Soiled insulation and chewed wiring need attention from the right trades once the roof is closed up.
Keeping them out next year
Exclusion is mostly maintenance, and the same fall checklist that protects the roof from rain protects it from wildlife.
Trim the trees. Squirrels and raccoons reach most roofs by limb. Keeping branches cut back six to eight feet from the roofline removes the highway. This is especially true for the big oaks and pines over older Tyler neighborhoods.
Clean the gutters and check the fascia behind them. Pine needles and leaves overflow the gutter, soak the fascia, and soften it for chewing. If the fascia is already soft, gutter repair and replacement work usually needs to include new fascia board behind it.
Upgrade the vent screens. Window screen and plastic mesh do not stop a determined raccoon. Quarter inch galvanized hardware cloth or purpose made metal vent guards do.
Close the ridge properly. If you have ridge vent, make sure the end caps are in place and there is a closure under the vent itself.
Schedule a fall check. A roof maintenance visit each fall catches the lifted ridge cap, the cracked boot, and the loose soffit panel before the first cold front sends something looking for them.
Frequently asked questions
Why do animals get into attics in the fall in East Texas? Cooling nights in October and November push squirrels, raccoons, and rats to look for a dry, warm place to nest through winter. An attic over a heated house with a gap at the eave, a loose soffit panel, a torn vent screen, or an opening at the ridge is exactly what they are looking for.
Where do animals usually enter a roof? The eave where the deck meets the fascia, soffit vents and loose soffit panels, gable and roof vents with damaged screens, the gap under the ridge cap, split plumbing boots, and the corners where a lower roof meets a wall. Tree limbs over the roof give them the path to all of it.
Does a roofer remove animals or just fix the roof? A roofer repairs the entry points and the damage. Live removal belongs to a licensed wildlife control operator. Removal comes first, then permanent repair of every opening.
Will animals in the attic cause roof leaks? Frequently. Chewed fascia, torn soffit, a lifted ridge cap, or a gnawed boot lets water in along with the animal, and nesting material blocks the attic airflow that keeps moisture from building up.
How do I keep animals out of my roof for good? Trim limbs back from the roof, replace soft fascia and soffit, screen every vent with heavy metal mesh, close the ridge, and have the eaves and penetrations checked each fall. Sealing one hole and leaving others open does not work.

Frequently Asked Questions
Why do animals get into attics in the fall in East Texas?
As nights cool in October and November, squirrels, raccoons, rats, and other wildlife look for a dry, warm place to nest through the winter. An attic above a conditioned house is ideal, and any roof with a soft spot at the eave, a loose soffit panel, a torn vent screen, or a gap at the ridge gives them a way in.
Where do animals usually enter a roof?
The most common entry points are the eave where the roof deck meets the fascia, soffit vents and loose soffit panels, gable and roof vents with damaged screens, the gap under the ridge cap, plumbing boots, and the corners where a lower roof meets a wall. Overhanging tree limbs give squirrels and raccoons a direct path to all of them.
Does a roofer remove animals or just fix the roof?
A roofing contractor repairs the entry points and the damage the animals caused. Removing a live animal, especially a raccoon that may have young in the attic, is a job for a licensed wildlife control operator. The right order is removal first, then a permanent repair of every opening so the problem does not return.
Will animals in the attic cause roof leaks?
Often, yes. Chewed fascia, torn soffit, a lifted ridge cap, or a boot gnawed open lets water in along with the animal. Nesting material also blocks attic airflow, which traps moisture and shortens shingle life. Insulation that has been soaked with urine or compressed by traffic loses its value and often needs replacement.
How do I keep animals out of my roof for good?
Trim limbs back at least six to eight feet from the roof, replace rotted fascia and soffit with sound material, fit vents with heavy gauge metal screen rather than plastic or window mesh, install a mesh or foam closure under the ridge cap, and have the eaves and penetrations checked each fall. Sealing the one hole you found while leaving three others open does not work.
