Hail damage to skylights often appears as small, circular dents or chips on the glass surface.

You might also see spiderweb cracks radiating from impact points, especially on tempered glass.

TL;DR:

• Hail can cause visible dents, chips, and cracks on skylights.
• Even small impacts can compromise the seal and lead to leaks.
• Look for starburst patterns or shallow depressions on the glass.
• Damaged seals are a common, yet often hidden, sign of hail impact.
• Prompt inspection and repair are key to preventing further water damage.

What Does Hail Damage to Skylights Look Like?

When hailstones strike your skylights, they can leave behind a variety of tell-tale signs. Understanding these can help you spot trouble early. You’re probably wondering about the specific marks left behind. Let’s break down what hail damage to skylights typically looks like.

Visible Impact Marks on Glass

The most obvious signs are physical marks on the glass itself. You might see small, circular dents. These are like tiny bruises on the skylight’s surface. Sometimes, you’ll notice chips, where small pieces of glass have been knocked away. These are more common on older or thinner glass.

Cracks and Fractures

Hailstones can cause cracks, too. These often start at the point of impact. They can spread outwards in a pattern resembling a spiderweb. This is especially true for tempered glass, which tends to shatter into smaller pieces. Even a hairline crack is a serious sign of damage that needs attention.

Shallow Dents and Depressions

Not all hail damage is dramatic. Sometimes, you’ll find shallow depressions or dimples. These might be hard to see unless the light hits them just right. They indicate that the hail impacted the surface with enough force to deform it. This can still weaken the glass over time.

Chipped or Damaged Edges

The edges of the skylight frame or the glass itself can also show damage. Hail might chip away at the sealant around the edges. It can also nick the metal or plastic frame. These subtle signs are easy to miss but can still lead to problems.

Compromised Seals and Frames

This is where things get tricky. Even if the glass looks okay, the hail could have damaged the seals. These seals keep water out. When they are compromised, water intrusion through roofing becomes a real possibility. You might not see any cracks, but a tiny gap can let moisture in.

The Sealant’s Story

The sealant is often the first line of defense. A strong hail impact can push or crack this material. Look for any signs of the sealant being pushed out of place. You might see small tears or gaps where it meets the frame. This is a critical indicator of potential leaks.

Frame Material Damage

The frame itself, whether metal or plastic, can also suffer. It might get dented or scratched. If the frame is weakened, it can affect the integrity of the entire skylight unit. This can make it more susceptible to further damage.

The Hidden Dangers of Hail Damage

It’s not just about the visible marks. The real danger often lies in what you can’t easily see. Hail damage can create problems that take time to surface. This is why a thorough inspection is so important.

How Hail Affects Skylight Integrity

Hailstones, especially larger ones, carry a lot of force. This force can do more than just dent glass. It can weaken the overall structure. Think of it like hitting a drum; even if it doesn’t break, it can still be affected. This weakening can lead to future issues.

Compromised Glazing

The glass panes themselves are called glazing. Hail can cause microscopic fractures within the glass. These tiny cracks might not be visible to the naked eye. However, they reduce the glass’s strength. Over time, temperature changes can cause these cracks to spread.

Sealant Degradation

Research shows that repeated stress on seals can lead to degradation. Hail impacts are a form of stress. Even if a seal looks intact, it might be weakened. This compromised seal is a prime candidate for developing leaks later on. It’s a classic example of water intrusion through roofing systems.

The Link Between Hail and Leaks

It might seem strange, but a skylight that looks fine after a storm can start leaking weeks or months later. This is a common problem. The initial hail impact may have created tiny openings. These openings allow moisture to slowly seep in. This is why understanding roof leak source clues is so vital.

Slow Seepage

The water doesn’t always gush in. Often, it’s a slow drip or seepage. This moisture can get trapped within your ceiling or wall cavities. It can go undetected for a long time. This leads to hidden mold growth and structural rot.

Expansion and Contraction

Materials expand and contract with temperature changes. A small crack or weakened seal from hail can be exacerbated by this. As the skylight expands and contracts, the damage can worsen. This can turn a minor issue into a significant leak.

Why You Should Not Ignore Skylight Damage

Ignoring even minor-looking hail damage to your skylight is a mistake. It’s like ignoring a small cut that could get infected. The potential for further damage is too high. You need to understand the risks involved.

Preventing Further Water Damage

Water damage can spread quickly. Once water gets into your home, it can ruin insulation, drywall, and even structural components. Addressing hail damage promptly can prevent these costly repairs. It’s about being proactive to prevent future damage.

Mold and Mildew Growth

Moisture is a breeding ground for mold and mildew. These can cause serious health risks for your family. Mold spores can spread through your HVAC system. Early detection and repair are essential for maintaining a healthy indoor environment.

Structural Weakening

Persistent leaks can weaken the structural integrity of your roof and ceiling. Wood can rot, and metal components can corrode. This can lead to more extensive and expensive repairs down the line. You should never wait to get professional help.

What to Do If You Suspect Hail Damage

If you’ve experienced a hailstorm and are concerned about your skylights, take action. Don’t wait for leaks to appear. A little bit of vigilance now can save you a lot of trouble later.

Visual Inspection Checklist

When you check your skylights, look for these specific signs:

• Dents or dimples on the glass.
• Chips or cracks, especially radiating from a point.
• Scratches or impacts on the frame.
• Signs of sealant separation or damage around the edges.
• Any pooling or staining on the interior ceiling around the skylight.

When to Call a Professional

If you see any of the signs above, or if you’re just unsure, it’s time to call an expert. Professionals have the tools and experience to identify subtle damage. They can assess the extent of the problem accurately. It’s important to schedule a free inspection if you suspect any damage.

Documenting the Damage

If you plan to file an insurance claim, documentation is key. Take clear photos of any damage you find. Note the date and time of the storm. This evidence is crucial for your claim. Learning how to document damage for a claim can make the process smoother.

Understanding Your Insurance

Dealing with insurance claims can be confusing. Many homeowners have insurance questions after damage occurs. Understanding your policy and working with experienced professionals can help navigate this process. Sometimes, wind damage insurance claims get disputed, so thorough documentation is even more important.

Conclusion

Hail damage to skylights can range from minor cosmetic imperfections to serious structural issues that lead to leaks. Recognizing the signs, from visible dents and cracks to compromised seals, is the first step. Even if the glass appears intact, hidden damage to seals can cause problems months later. Prompt inspection and repair by a qualified professional are essential to protect your home from water damage, mold, and further structural issues.

Can hail damage a skylight without breaking the glass?

Yes, absolutely. Hail can cause dents, chips, and microscopic fractures in the glass, or damage the seals and frame, without causing a complete break. This type of damage can still lead to leaks and structural weakness over time.

How long does it take for hail damage to a skylight to cause a leak?

It can take weeks or even months for hail damage to a skylight to result in a visible leak. The initial impact may create tiny openings or weaken seals that gradually allow moisture to penetrate, especially with temperature fluctuations.

Should I try to repair hail damage to my skylight myself?

It’s generally not recommended to repair hail damage to skylights yourself, especially if the glass is cracked or the seals are compromised. These repairs often require specialized knowledge and materials to ensure a proper, watertight seal and structural integrity. It’s best to call a professional right away.

What should I do if I find hail damage on my skylight?

If you find hail damage on your skylight, document it with photos and notes. Then, contact a reputable damage restoration company or roofing contractor for a professional inspection.
