The short answer
How Hail Damages Skylights
Hailstones strike with enough force to crack tempered glass or polycarbonate skylights. The impact point may look small, but the stress can spread through the whole pane. Older skylights are more vulnerable because their seals weaken over time and the glass becomes brittle.
A single hailstone can create a hairline crack that lets rainwater seep through. Even if the skylight does not break fully, the impact can loosen the frame or damage the flashing around it. That hidden damage often leads to leaks later. You should check the skylight from inside and outside after any hailstorm.
- Look for visible cracks, chips, or shattered sections
- Check the frame for dents or gaps
- Feel around the edges for dampness or drafts
- Inspect the ceiling below for water stains
- Note the size and thickness of the glass if possible
What Happens After a Break
When a skylight shatters, rain and debris can enter your attic and living spaces. Moisture soaks into drywall, insulation, and wooden framing. That water can spread quickly through the ceiling and walls, causing stains, warping, and mold growth.
You should act quickly to limit the damage. Move furniture away from the leak and place a bucket under any dripping water. If the ceiling begins to sag, that is a sign of heavy water buildup. Do not stand directly under the damaged area, as the ceiling could collapse.
- Turn off power to the room if water reaches outlets
- Remove wet rugs or furniture from the area
- Open windows to improve air circulation
- Take photos of the damage for your records
- Do not attempt to repair the skylight yourself
Checking for Water Damage
After a skylight breaks, you need to check for hidden water damage beyond the visible leak. Water can travel along joists and drywall, pooling far from the original break. Look for discoloration, bubbling paint, or a musty smell in the attic and rooms below.
A professional inspection can reveal moisture inside walls and ceilings that you cannot see. The pros use moisture meters and thermal imaging to find wet areas. This step is important because trapped water can lead to rot and mold if left untreated. If you live in Bellingham, keep an eye on the ceiling near the skylight after storms.
- Use a flashlight to inspect attic rafters and insulation
- Press on drywall to feel for soft or spongy spots
- Check window frames and walls near the skylight
- Look for peeling paint or discolored caulk
- Smell for musty odors that indicate mold growth
Repairing the Damage
Repairing a shattered skylight involves replacing the glass or the entire unit, depending on the damage. The pros will also fix the flashing and seals to prevent future leaks. Any water-damaged drywall, insulation, or flooring must be removed and replaced to avoid mold growth.
The cost of repair depends on the skylight size, the type of glass, and how much water damage occurred. It often ranges from a few hundred to several thousand dollars. You should get a clear picture of the damage before deciding on the next step. Your insurance company may help, but policies vary, and your insurer decides what is covered.
- Replace cracked glass with impact-resistant options
- Seal the frame with fresh flashing and caulk
- Remove and replace soaked drywall and insulation
- Dry out the attic space thoroughly
- Consider adding a protective screen over the skylight
Preventing Future Hail Damage
You can reduce the risk of future shattering by choosing impact-resistant skylight materials. Tempered glass is stronger than standard glass, and laminated glass holds together when broken. Polycarbonate units are lightweight and very resistant to hail strikes.
Regular maintenance also helps. Inspect the skylight seals and flashing each year, especially before the wet season. Clear any debris from the roof that could shift and strike the skylight during a storm. If you live in Bellingham, include the skylight in your routine roof checks.
- Install impact-resistant glass or polycarbonate panels
- Trim overhanging branches that could fall during storms
- Replace worn seals and flashing promptly
- Check the skylight after every hailstorm
- Keep gutters clear to prevent water backup near the roof

How can I tell if my skylight is leaking after hail?
Look for water stains on the ceiling or walls below the skylight. Feel the frame for dampness and check the attic for wet insulation. A musty smell or bubbling paint also signals a leak. If you notice any of these signs, act quickly to prevent further damage.
Can a small crack in a skylight be repaired?
A small crack can sometimes be sealed with a clear resin or patch, but it is often temporary. The impact may have weakened the whole pane, so a full replacement is usually safer. The pros can assess the crack and recommend the right option for your situation.
Will my insurance cover skylight hail damage?
Coverage depends on your specific policy and the cause of the damage. Hail damage is often covered under homeowners insurance, but deductibles and limits vary. Policies vary, and your insurer decides what is covered. Check your policy documents and contact your insurance company for details.
