Direct answer: If a raccoon damaged a roof vent, the usual problem is a bent vent hood, torn vent screen, or loosened fasteners that leave an opening into the attic. Start by confirming whether the vent body is still solid and weather-tight or whether the animal pulled the whole assembly loose.
Most likely: Most often, the vent cover gets peeled up or the screen gets ripped out while the surrounding shingles and roof deck stay mostly intact.
Look at this like a roofer would: first decide whether you have an active animal entry, a water-entry problem, or both. Reality check: if a raccoon could open it once, a flimsy patch usually won’t last the next night. Common wrong move: sealing the hole before you know the animal is out.
Don’t start with: Don’t start with roof cement, spray foam, or hardware cloth stuffed into the opening. Those quick patches often trap moisture, block airflow, or hide a leak path.
The metal hood is peeled back, dented, or sitting crooked, but the vent opening is still recognizable.
Start here: Check whether the vent body is still fastened tight to the roof and whether rain can blow straight into the opening.
You can see straight into the vent throat, or the screen is hanging loose with clawed edges.
Start here: Confirm whether only the roof vent screen failed or the whole roof vent cover was twisted loose with it.
You see torn insulation, droppings, nesting material, or daylight around the vent from inside the attic.
Start here: Assume active entry until proven otherwise and do not close the opening permanently until the animal issue is handled.
There is wet sheathing, dark staining, or a fresh ceiling spot below the damaged vent area.
Start here: Separate rain entry from condensation by checking for torn flashing, lifted shingles, and a direct opening at the vent.
Raccoons usually grab the exposed hood or cap first. You’ll often see bent sheet metal, tooth marks, or a hood sitting higher on one side.
Quick check: From the ground or a safe ladder view, compare the damaged vent to another vent on the roof. A lifted profile usually stands out right away.
If the vent body still looks mostly square but the opening is exposed, the screen was likely the weak point.
Quick check: Use a flashlight from the attic or a phone zoom from outside to see whether the screen is missing while the vent housing stays in place.
A determined animal can work the edges until the flange lifts, especially on older vents or brittle roofing around the base.
Quick check: Look for a vent base that no longer sits flat, exposed nail heads, or shingles buckled around the vent flange.
If the animal kept digging, the vent may be only part of the problem. Water stains and soft roof areas point that way.
Quick check: From the attic, look for cracked decking, daylight beyond the vent opening, or wet wood around the vent footprint.
You need to separate a general attic roof vent from a plumbing vent cover or another roof penetration, and you do not want to trap an animal inside.
Next move: You know whether this is a simple damaged roof vent cover or an active wildlife-entry problem that needs animal removal first. If you cannot tell what was damaged or whether the opening is active, treat it as an open roof penetration and get a roofer or wildlife pro to inspect it.
What to conclude: A clean, inactive opening is a repair job. An active opening is first an animal-removal job, then a repair job.
Attic clues tell you whether the damage is limited to the vent cover or whether water and structural damage are already involved.
Next move: You can tell whether the vent itself is the main repair or whether the surrounding roof materials were opened up too. If the attic is inaccessible or the damage area is hidden, you will need an exterior inspection by someone equipped to work the roof safely.
What to conclude: Dry wood and a clean opening usually point to a vent-only repair. Wet sheathing, soft decking, or wide staining point to roof repair along with vent replacement.
The outside view tells you whether the vent hood, screen, flange, or surrounding shingles actually failed, and that decides whether this is a simple replacement or a roofing repair.
Next move: You can sort the damage into one of three paths: screen-only failure, vent-cover failure, or full roof-area damage. If you cannot inspect it safely from outside, skip the guesswork and have a roofer inspect and secure it.
A temporary weather-tight block buys time, but it should not create a hidden leak or trap an animal inside.
Next move: You reduce the chance of another animal entry or immediate rain intrusion until the permanent repair is made. If you cannot secure it without climbing unsafely or the base is loose and leaking, call a roofer for same-day protection.
Once you know what actually failed, you can avoid a weak patch and fix the part that raccoons opened up.
A good result: The opening is weather-tight again, airflow is restored, and the raccoon no longer has an easy entry point.
If not: If water staining grows, the new vent will not stay tight, or animals keep targeting the area, the roof around the vent needs a closer professional repair.
What to conclude: A clean replacement solves vent-only damage. Repeat leaks or movement mean the roof field around the vent was compromised too.

Only if the metal is lightly bent and the vent still sits tight and weather-tight. Once the hood is creased hard, the screen is torn out, or the base has lifted, replacement is usually the better fix.
Only after you know the raccoon is out. Sealing first can trap an animal inside the attic or push it to tear out another weak spot nearby.
Sometimes, but not always. Raccoons often start with the screen and then pry up the hood or loosen the vent flange. That is why the attic-side check matters before you buy anything.
Yes. A bent hood or lifted flange can let in wind-driven rain, and even a small opening can wet the sheathing over time. Light stains often show up before you notice an obvious drip.
Call a roofer if the vent base is loose, shingles are torn, flashing is disturbed, the roof deck feels soft, or the roof is not safe to access. At that point it is a roof repair with a vent replacement, not just a simple patch.
