The short answer
How Storms Damage Solar Panels
Hail is the most direct threat. Large hailstones can crack the tempered glass surface or shatter the photovoltaic cells underneath. Even a small crack can let moisture inside, reducing power output and creating a path for water to reach your roof deck.
High winds can rip panels off their mounts if the racking is not properly secured, or they can send tree limbs and other debris flying into the array. A direct hit from a heavy branch can dent the frame, break the glass, or loosen the bolts that hold the panels in place.
What to Check After a Storm
Look at your panels from the ground first. Use binoculars to spot cracks, chips, or displaced panels. Check the roof for fallen branches, leaves, or other debris that might have struck the array or blocked drainage paths.
If you see damage, do not climb onto the roof yourself, especially if it is wet or windy. Call a local water damage pro to inspect the roof and the solar system. They can identify whether the panel damage has led to water intrusion under the shingles or into the attic.
- Cracked or shattered glass
- Dents or bends in the aluminum frame
- Loose or tilted panels
- Broken or missing mounting bolts
- Water stains on the ceiling inside your home
- Debris piled against the panels
What Happens When Water Gets In
A cracked solar panel does not always leak immediately, but over time rain and melting snow can seep through the gap. The water can travel down the roof slope and find its way under the shingles, into the underlayment, and eventually into your attic or wall cavities.
Once water is inside, it can soak insulation, drywall, and wooden framing. That creates conditions for mold growth and structural rot. Acting quickly after a storm can limit the extent of the damage and make cleanup simpler.
Steps to Protect Your Roof
Trim overhanging branches near your roof before storm season. Keep gutters and downspouts clear so water flows off the roof quickly. Staying ahead of debris can reduce the risk of panel damage during heavy storms.
Have a professional inspect the mounting system and seals around the panels at least once a year. They can tighten loose bolts, replace worn flashing, and check that the panels are still flat against the roof. This kind of maintenance helps the array withstand strong winds and hail.
When to Call a Water Damage Pro
If your solar panels are damaged or you suspect water has entered your home, contact a local water damage pro as soon as you can. They can assess the roof condition, remove debris, and set up drying equipment to prevent mold and rot.
The pros will typically inspect the attic and walls with moisture meters to find hidden wet spots. They can also coordinate with a roof repair specialist if the shingles or underlayment are compromised. Acting early often reduces the overall repair effort.
Policies vary, and your insurer decides what is covered. Check your policy to see if storm damage to solar panels is included, and document the damage with photos before any cleanup begins.

Will a small crack in a solar panel cause a roof leak?
A small crack can allow water to seep through over time, especially during heavy rain. It may not leak right away, but the risk increases with each storm. Have a pro inspect the panel and the roof underneath to catch any moisture before it spreads.
Can I walk on my roof to check the panels after a storm?
Walking on a wet or damaged roof is dangerous. The surface may be slick, and hidden damage could weaken the structure. Stay on the ground and use binoculars to inspect. If you need a closer look, hire a local water damage pro who has the proper safety equipment.
How long does it take for water damage to show after a storm?
Water stains and damp spots can appear within hours, but sometimes it takes days or weeks for the moisture to travel through insulation and drywall. By the time you see a stain, the damage may be extensive. If you suspect a leak, schedule an inspection soon.
