Direct answer: If a raccoon ripped the bathroom vent screen, treat it as more than a screen problem until you confirm the vent cap, damper, duct connection, and surrounding shingles are still intact. The safest first move is a ground-level visual check and an attic look for daylight, loose ducting, or water marks.
Most likely: Most often, the screen is torn because the raccoon was trying to get into the warm exhaust opening, and the real repair ends up being a damaged bathroom roof vent cap or a loose bathroom exhaust duct at the vent.
Separate this early: a torn exterior screen is one job, a broken vent hood or disconnected bath fan duct is a bigger one. Reality check: if a raccoon got interested enough to tear metal or plastic, the damage is usually rougher than it looks from the yard. Common wrong move: patching the hole from inside the attic and leaving the roof-side opening loose and weather-exposed.
Don’t start with: Do not start by stapling random mesh over the opening or smearing roof cement around the cap. That often traps the damper, restricts airflow, and hides roof damage.
From the ground, the hood shape still looks normal, but the screen is hanging, missing, or peeled back.
Start here: Start with an attic check for daylight, insulation disturbance, and a loose bathroom exhaust duct before deciding it is only a screen repair.
The hood is crooked, the flap is gone, or the cap body looks chewed, split, or pulled up.
Start here: Treat this as a damaged bathroom roof vent cap first. The screen is secondary if the cap body no longer sheds water correctly.
You hear the fan, but the bathroom stays steamy or you feel air moving in the attic near the vent line.
Start here: Check the bathroom exhaust duct connection at the roof vent and at the fan housing. Animal pulling often disconnects flexible duct.
You see dark roof sheathing, wet insulation, or a ceiling stain near the bathroom vent path.
Start here: Look for flashing damage, lifted shingles, or an open vent body before assuming the torn screen caused all the moisture.
You have a visible opening, but the hood body is still square to the roof, the damper moves, and there is no sign of water entry or a loose duct.
Quick check: From the attic and from the ground, confirm the cap is firmly seated, the opening is still covered by the hood, and the duct is attached.
Raccoons commonly bend light metal, crack plastic hoods, or rip fasteners loose while trying to widen the opening.
Quick check: Look for a twisted hood, broken corners, missing flap, exposed fasteners, or a cap that no longer sits flat on the roof.
If the animal tugged hard on the cap, the duct inside can slip off the collar or tear at the connection.
Quick check: In the attic, look for a disconnected or sagging bathroom exhaust duct, loose clamp, or moist air blowing near the vent line when the fan runs.
Clawing and prying can lift shingles, crack seal lines, or loosen the vent flange enough to let rain in.
Quick check: Check for lifted shingles, gaps under the vent flange, fresh water marks on the roof deck, or damp insulation below the vent.
Bathroom exhaust vents, plumbing vents, and attic vents can look similar from the yard, and the repair path changes fast if you identify the wrong one.
Next move: You know whether you are dealing with the bathroom fan vent itself, which keeps the repair focused. If you cannot confirm the vent type, stop short of patching it and get a roofer or handyman to identify it on-site.
What to conclude: A bathroom exhaust vent can usually be repaired at the cap, screen, duct connection, or flashing. A different vent type needs a different fix.
The attic tells you whether the damage is only outside or if the duct, sheathing, or insulation took a hit too.
Next move: If the duct is attached and the roof deck is dry, you may be dealing with an exterior vent-cap repair only. If you find a loose duct, wet sheathing, or clear daylight around the vent body, the repair is bigger than a screen patch.
What to conclude: A torn screen alone does not usually cause attic airflow problems. A loose duct or shifted vent cap does.
This separates a simple guard repair from a full bathroom roof vent cap replacement or roof repair.
Next move: A cap that is solid, aligned, and weather-tight may only need a proper replacement screen or animal guard. If the hood is broken, loose, or no longer sheds water cleanly, replace the bathroom roof vent cap rather than trying to patch around it.
This keeps you from overbuying parts or doing a weak patch that fails the next storm.
Next move: You end up fixing the actual failure point instead of just covering the opening. If the vent opening shape is odd, the roof pitch is difficult, or the surrounding roofing is damaged, bring in a roofer for the exterior repair and secure the attic side from animal entry only as a temporary measure.
A bathroom vent repair is not done until the fan exhausts outside, the damper moves, and the roof stays dry.
A good result: The fan clears steam normally, the attic stays dry, and the vent opening is protected again.
If not: If airflow is still weak or moisture still appears, the problem may include a crushed duct run, a stuck damper, or a broader venting issue that needs a dedicated bath-fan vent inspection.
What to conclude: Good repair results are simple: outside exhaust, no attic leakage, and no new water marks.

Only if the bathroom roof vent cap itself is still solid and the patch will not block the damper or choke airflow. If the hood is bent, cracked, or loose, patching the screen alone is usually a short-term fix.
Check the attic for daylight, loose ducting, wet wood, and disturbed insulation. Outside, look for a crooked hood, cracked plastic, missing flap, or shingles lifted around the vent. Those signs point to a bigger repair than screen replacement.
Not by itself in every case, because the hood is what sheds most rain. But if the raccoon also loosened the cap, flange, or nearby shingles, leaks can start quickly. That is why the roof-side inspection matters.
The duct may have pulled loose in the attic, the damper may be stuck, or the vent cap opening may still be partly blocked. A good repair should restore strong outside airflow, not just close the animal entry point.
Replace the whole cap when the hood, collar, flap, or mounting area is damaged. Replace only the screen when the cap is firmly attached, weather-tight, and still operating normally.
Sometimes, yes, if the damage is limited and the roof is easy and safe to access. If the roof is steep, the cap is tied into damaged shingles, or you find attic moisture or structural damage, this is a good time to call a roofer.
