Why Does My Siding Have Holes After a Hail Storm?
Last updated October 26, 2026
The short answer
How Hail Damages Siding
Hailstones vary in size and hardness. Large stones falling at high speed can crack or punch through siding, leaving holes that expose the wall underneath. The impact may also loosen the siding's locking mechanism, creating gaps that look like holes.
The type of siding matters. Vinyl is more flexible but can crack or shatter. Aluminum dents easily, and the dent can split. Fiber cement is brittle and may chip or hole. Even small hail can cause damage if the wind drives it at an angle.
What to Look For
After a storm, walk around your house and inspect all siding, not just the side facing the storm. Look for round holes, cracks, or dents. Also check for siding that has shifted or popped out of place, which can create gaps.
Pay attention to areas around windows, doors, and corners, as these are more vulnerable. If you see holes, gently press on the surrounding siding to check for soft spots. Moisture behind the siding can cause rot and mold over time.
Why Holes Matter
Holes in siding allow rainwater to enter the wall cavity. This moisture can soak the insulation, framing, and drywall, leading to structural damage and mold growth. In a humid climate like St. Petersburg, the risk of mold increases quickly.
Even small holes can let in pests like insects or rodents. Water that gets behind siding often travels downward, causing damage far from the original hole. You may not notice the problem until it becomes a bigger issue.
Temporary Protection
While you arrange for repairs, you can protect the area. Use a piece of plastic sheeting and tape it over the holes, making sure it extends beyond the damaged area. This keeps out rain and pests.
Do not seal holes with caulk or foam if the siding is wet. Moisture trapped behind the siding can cause more damage. If you notice water stains or dampness inside your home, that is a sign water has already entered the wall.
When to Call the Pros
If you see holes, cracks, or large dents, it is wise to have a professional inspect the siding. They can determine the extent of the damage and whether water has already penetrated the wall. They also can check for hidden damage to the sheathing.
The pros can replace damaged panels and ensure the siding is properly sealed. If water has gotten inside, a water damage inspection can reveal the full scope. In St. Petersburg, where storms bring heavy rain, addressing this early helps avoid bigger problems.
- Inspect all sides of your home, not just the storm-facing side.
- Look for holes, cracks, dents, or siding that has shifted out of place.
- Check around windows, doors, and corners for gaps.
- Feel for soft spots or moisture behind the siding.
- Take photos of the damage for your records.
- Keep damaged areas covered with plastic until repairs are made.
What to Expect from Repairs
Repair work usually involves removing the damaged siding panels and inspecting the underlying wall. If the sheathing is wet or rotted, that must be replaced before new siding goes on. The pros will match the siding type and color as closely as possible.
Costs depend on the extent of the damage, the type of siding, and the size of the area. A single panel replacement is often less involved than repairing water damage behind the siding. Your insurance company may cover hail damage, but policies vary.

Can small hail holes cause leaks?
Yes, even small holes can let rainwater seep behind siding. Over time, this moisture can damage the wall structure and lead to mold. It is sensible to have any hole inspected and repaired promptly.
How long does siding repair take?
The time depends on the damage size and siding type. A simple panel replacement may be done in a few hours, while larger areas or water damage behind the siding can take longer. The pros can give you a timeline after inspecting.
Will my insurance cover hail damage to siding?
Policies vary, and your insurer decides what is covered. Hail damage is often covered, but you need to check your policy and file a claim if you have one. Document the damage with photos and keep records of any repairs.
