The short answer
How Storms Harm Vents
Strong winds during a storm can bend or tear vent covers, especially on roof vents or wall vents made of lightweight plastic or aluminum. Hail can dent metal louvers or crack plastic ones, and tree branches or other debris can strike vents hard enough to break them. Once a vent is damaged, it may no longer keep rain and pests out.
Water that gets into a vent can travel along ductwork and soak insulation, drywall, or wood framing. That hidden moisture can lead to mold growth and rot over time. If you live in Orem, where storms can bring sudden hail and strong gusts, checking your vents after a storm is a smart habit.
Signs of Vent Damage
Look for visible dents, cracks, or bent fins on vent covers. Check if the vent is loose or if the screws or clips that hold it in place have pulled out. Also listen for whistling sounds on windy days, which can indicate a gap or opening that shouldn't be there.
Inside your home, feel around vents for drafts or look for water stains on ceilings or walls near vent locations. Musty odors near a vent can point to moisture buildup. If you spot any of these signs, take a closer look at the vent and the area around it.
- Dents or cracks in plastic or metal covers
- Loose or missing screws and clips
- Water stains on ceilings or walls near vents
- Whistling or rattling noises during wind
- Visible gaps between the vent and the wall or roof
What You Can Do Yourself
For minor damage, you may be able to reattach a loose vent cover with new screws or apply a small patch to a crack using exterior-grade sealant. Make sure the vent is clean and clear of debris before you make any repairs. Always work safely, and if the vent is high up, use a sturdy ladder and have someone spot you.
If a vent cover is badly bent or broken, replacing it with a new one is often the right option. You can buy standard vent covers at a home improvement store, but match the size and style to your existing vent. For roof vents, consider hiring a professional if you are not comfortable working at heights.
When to Call the Pros
If water has already entered your home through a damaged vent, you may need professional help to dry out walls, insulation, or flooring. Water damage can spread quickly, so act fast to prevent mold. Local water damage pros have the equipment to detect hidden moisture and dry affected areas thoroughly.
They can also help you assess the full extent of the damage, including any issues in your attic or crawlspace that you can't see. If you have a historic home with unique vent designs, or a luxury home with custom vents, a professional can help you find appropriate replacements. For any significant water intrusion, call a pro rather than attempting major repairs yourself.
- Water stains or dampness on walls or ceilings
- Musty smell coming from vents
- Visible mold growth near vent openings
- Vent is on a steep or high roof that is unsafe to access
- You suspect water has soaked into insulation or drywall
Preventing Future Storm Damage
After you repair or replace a vent, take steps to make it more storm-resistant. Choose vent covers made of heavy-gauge metal or impact-resistant plastic. Ensure vent covers are securely fastened with corrosion-resistant screws. Trim tree branches that hang over your roof, as they can break off during storms and strike vents.
Consider installing storm-resistant vent covers that are designed to withstand high winds and hail. Some vents come with built-in insect screens that also block debris. Regularly inspect your vents, especially before storm season, to catch small problems before they become big ones. This simple maintenance can save you from costly water damage later.

What should I do right after a storm?
Check your vents for visible damage, such as dents, cracks, or loose covers. If a vent is broken, temporarily cover it with a piece of plastic or plywood to keep water out. Then call a professional to assess and repair the damage.
Can I repair a cracked vent cover myself?
For small cracks, you can apply exterior-grade sealant or tape designed for outdoor use. But if the crack is large or the vent is misshapen, replacement is safer. A damaged vent may not seal properly, letting water in during the next storm.
Will my insurance help with storm vent damage?
Policies vary, and your insurer decides what is covered. Storm damage to your home's exterior, including vents, may be covered under your homeowners policy. Check your policy documents and contact your insurance company to discuss your specific situation.
