5 Quick Temporary Fixes for a Leaking Skylight

When water is dripping into your living room, you need solutions, not theories. This guide gets straight to the point. We’ll skip the fluff and give you the actionable steps you need to take right now to stop a skylight leak and minimize water damage. From using heavy-duty tape on a small crack to properly securing a tarp over a larger problem area, we have you covered. Each step is explained clearly, helping you create a reliable temporary fix for a leaking skylight that will hold until our team can get there to implement a permanent, professional repair that protects your home for years to come.

Key Takeaways

• Your Safety is Non-Negotiable: Working on a roof is risky. Always use proper safety gear and have a spotter. If you feel unsure or the conditions are poor, the safest and smartest choice is to call a professional instead of climbing the ladder.
• A Temporary Patch Buys You Time: Quick fixes like heavy-duty tape, a tarp, or silicone sealant are meant to stop immediate water damage, not solve the problem forever. Use them to control the situation until an expert can arrive.
• Leaks Signal Deeper Issues: A dripping skylight often points to a bigger problem like failed flashing or worn-out seals. After applying a temporary fix, your next step should always be scheduling a professional inspection to find and fix the true source of the leak.

Why Is Your Skylight Leaking?

That steady drip, drip, drip from your skylight is more than just an annoyance—it’s a sign that something is wrong. Before you climb up on the roof, it helps to understand what causes these leaks in the first place. Most of the time, the problem comes down to one of three things: the natural aging of materials, issues with the seals and flashing around the skylight, or blockages that are trapping water where it shouldn’t be. Figuring out the root cause is the first step toward a solid, lasting fix.

Understanding Age and Material Wear

Just like any other part of your home, skylights and the materials around them have a lifespan. Constant exposure to the Southern California sun, wind, and rain eventually takes a toll. Over the years, the weather seals and gaskets that keep your skylight watertight can dry out, become brittle, and crack. This creates tiny openings for water to sneak through. The materials themselves can also degrade. While high-quality components are designed to last, even the best materials will wear down over time, making an older skylight more susceptible to leaks.

Identifying Problems with Flashing and Seals

One of the most common culprits behind a leaky skylight is faulty flashing. Flashing is the metal material installed around your skylight to direct water away from the opening and down your roof. If this flashing was installed incorrectly, or if it has become damaged or corroded, it can’t do its job. Water will find its way underneath and into your home. Similarly, worn-out weather seals around the glass pane are a frequent source of leaks. A thorough roof inspection can pinpoint if your flashing or seals are the problem, ensuring the right issue gets fixed.

Checking for Debris and Ice Dams

Your roof needs to be clear for water to drain properly. When leaves, pine needles, and other debris pile up around the top or sides of your skylight, they create a dam. This blockage traps rainwater, allowing it to pool up against the skylight’s seals. With nowhere else to go, the standing water can eventually seep through even the smallest cracks. While ice dams aren’t a major concern in our area, these debris dams create the same damaging effect. Keeping the area around your skylight clean is a simple but crucial part of preventing leaks and is a key part of routine roof maintenance.

Your DIY Toolkit for a Temporary Fix

Before you even think about climbing a ladder, let’s talk about what you’ll need. Having the right supplies on hand makes a temporary fix faster, safer, and more effective. Think of this as your emergency kit for a leaky skylight. Gathering these items first will save you from making multiple trips up and down the ladder and help you create a patch that can hold up until a professional arrives. Remember, the goal here is a short-term solution to prevent further water damage inside your home. This isn’t a permanent repair, but a solid temporary patch can give you peace of mind. For a lasting solution, you’ll want to schedule a professional roofing service to address the root cause of the leak.

Essential Waterproofing Materials

Your first line of defense is creating a waterproof barrier. A heavy-duty tarp or a roll of thick plastic sheeting is perfect for covering the entire skylight area if the leak is significant. For smaller gaps or cracks, roofing cement or a high-quality flashing tape can work wonders. These materials are designed to adhere strongly to roofing surfaces and withstand the elements. When you’re at the hardware store, make sure you’re buying products specifically made for exterior use. You need materials that can handle direct sun and rain without quickly degrading.

The Right Tools for the Job

You don’t need a professional-grade workshop, but a few key tools will make the job much easier. Start with a sturdy ladder that can safely reach your roof. You’ll also want a utility knife for cutting tarps or tape, a putty knife to apply roofing cement, and a caulk gun if you’re using silicone sealant. It’s crucial to use the right kind of sealant—look for roof-grade flashing sealants or products designed for exterior conditions. Avoid using generic interior caulk, as it simply won’t hold up against the weather. Having the right tools ensures your temporary skylight repair is as secure as possible.

Must-Have Safety Gear

This is the most important part of your toolkit. Never get on a roof without the proper safety equipment. Start with sturdy, non-slip shoes with good grip. Heavy-duty work gloves will protect your hands from rough roofing materials and sharp edges. Safety glasses are also a good idea to shield your eyes from debris. Most importantly, never work alone. Always have a spotter on the ground who can hold the ladder and be there in case of an emergency. Your safety is the top priority, and if you ever feel unsure or unsafe, it’s always best to contact a professional instead.

How to Safely Inspect the Leak

Before you can apply a temporary fix, you need to find where the water is getting in. This detective work is the most important step, but it also carries the most risk. Getting up on your roof requires careful planning and a serious respect for heights. If you feel even slightly unsure about climbing onto your roof, your best and safest option is to call for a professional roof inspection. A trained expert can quickly and safely identify the problem without putting you in harm’s way. If you decide to proceed, make sure you’re taking every precaution to stay safe while you investigate the source of the leak.

Key Safety Checks Before You Start

Your safety is the top priority. Working on a roof is dangerous, and a fall can lead to severe injuries. First, never attempt to inspect your roof alone; always have a spotter on the ground who can assist if needed. Wear sturdy, rubber-soled shoes for the best possible grip. Most importantly, never step, sit, or put any weight on the skylight itself. The glass or acrylic is not designed to support a person’s weight and can easily break. Plan your path on the roof, moving carefully and deliberately on the shingles or other solid roofing materials. If your roof is steep or you feel uneasy, it’s time to stop and call in the pros.

Pinpointing the Source of the Leak

Water is tricky and can travel from the entry point before it drips into your home, so the leak might not be where you think it is. Start your inspection by looking at the area directly around the skylight. Check the flashing—the metal strips that seal the joint between the skylight and the roof. Look for any gaps, cracks, or areas where the sealant has pulled away. Debris like leaves and twigs can also pile up around the skylight, trapping water and forcing it under the flashing. Clear away any buildup and examine the shingles immediately surrounding the frame for any that are cracked, loose, or missing.

Weather Conditions to Watch For

The weather plays a huge role in both causing leaks and creating safe conditions for an inspection. Never go on your roof during rain, high winds, or if there’s any ice or snow. A wet roof is incredibly slippery and hazardous. While winter weather can create ice dams that push water under seals, heavy Southern California rain can expose a weakness that went unnoticed during drier months. The ideal time for an inspection is on a clear, dry day. If you’re dealing with an active leak during a storm, your immediate focus should be on managing the water inside your home and calling for professional roofing services as soon as the weather clears.

5 Effective Temporary Fixes for a Leaky Skylight

Discovering a leak in your skylight is stressful, but don’t panic. While you’ll need a professional for a permanent fix, there are several things you can do right now to manage the situation and prevent further water damage. These temporary solutions are designed to be quick, effective, and hold things over until an expert can assess the problem. Remember, safety is your top priority. If you don’t feel comfortable getting on your roof, it’s always best to wait for a professional. But if you can safely access the area, these five fixes can make a big difference.

Applying Strong Tape for Small Cracks

For minor cracks in the glass or frame, a strong, waterproof tape can be your best friend. This is the quickest and easiest temporary fix for small-scale problems. You’ll want to use something heavy-duty like Clear Gorilla Tape or even classic duct tape. Before applying, make sure the surface of the skylight is completely clean and dry, otherwise the tape won’t stick properly. Apply the tape smoothly over the crack, pressing down firmly to create a tight seal that will act as a barrier against water. This simple patch can effectively stop a small leak in its tracks while you arrange for a more permanent roof repair.

Using Plastic Sheeting to Cover the Area

If you’re dealing with more than a tiny crack, plastic sheeting is a great next step. Head to a hardware store and get a thick piece of plastic, ideally between 5 and 10 mil. You’ll also need some strong, double-sided sticky tape. After cleaning and drying the area around the leak, apply the double-sided tape to the skylight frame. Then, carefully press the plastic sheeting onto the tape, ensuring you create a complete, waterproof seal all the way around the opening. This method is excellent for covering larger problem areas and provides more robust protection than tape alone, keeping your home dry until you can schedule proper skylight services.

Installing a Tarp for Larger Damage

When the damage is significant, a tarp is your go-to solution. This is especially useful after a storm or if a large section of the skylight has been compromised. Choose a tarp that is big enough to cover the entire skylight with plenty of overhang on all sides. Drape it over the skylight and secure it tightly. A great way to do this is by using a ratchet strap wrapped around the outside of the skylight curb (the part that rises from the roof). This cinches the tarp down and prevents it from blowing away in the wind. This method provides a strong, temporary shield against the elements and is a crucial step in managing serious storm damage.

Sealing Gaps with Silicone

Sometimes, the leak isn’t from a crack in the glass but from a failing seal where the skylight meets the roof. If you can safely identify a gap in the flashing or frame, applying a waterproof silicone sealant can temporarily stop the leak. Clean the area thoroughly to remove any dirt or old, cracked sealant. Apply a generous bead of silicone directly into the gap, making sure it covers both the frame and the surrounding roofing material to form a new, watertight barrier. This requires a bit more precision, but it can be very effective for leaks caused by aging seals. Just remember, this is a patch, not a replacement for a professional roof inspection.

Managing Water Drips Inside

While you’re addressing the problem on the roof, don’t forget to manage the water that’s already inside. Place a bucket or towels under the drip to protect your floors and furniture. To deal with the excess moisture in the air, run a dehumidifier in the room, setting it to around 50-55% humidity. You can also reduce the overall humidity in your home by putting lids on pots when you cook and taking shorter showers. Controlling the interior environment helps prevent secondary issues like mold growth and water stains on your ceiling while you wait for a permanent solution to your leaky skylight.

When to Call a Professional

A temporary fix can be a lifesaver in a pinch, but it’s crucial to know when a problem is beyond a DIY solution. While it’s tempting to try and handle repairs yourself, some situations require the expertise, tools, and safety protocols of a professional. Attempting a complex repair without the right knowledge can unfortunately lead to more extensive damage, turning a small issue into a costly headache. A professional roofer can accurately diagnose the root cause of the leak—whether it’s from the skylight itself or another part of your roof—and provide a permanent solution. Calling in an expert isn’t giving up; it’s making a smart decision to protect your home and your safety. At Cert-A-Roof, our team is equipped to handle all types of roofing services, ensuring the job is done right the first time.

Signs the Damage Is Too Severe for DIY

If you’ve inspected the skylight and can’t easily pinpoint the source of the leak, it’s a strong sign you need professional help. Leaks can be deceptive, with water traveling from the entry point before showing up on your ceiling. If you notice multiple water stains, significant rot around the skylight frame, or large cracks in the glass or dome, a simple patch won’t be enough. Some skylights, especially older or more complex models, have intricate sealing systems that are difficult to repair without specialized experience. Pushing forward with a DIY fix in these situations can worsen the damage and lead to more significant water intrusion.

Recognizing Unsafe Repair Situations

Your safety should always be the top priority. Working on any roof carries inherent risks, from steep pitches to slippery surfaces. If you feel uncomfortable or unsafe at any point, it’s time to stop and call a professional. It’s also critical to remember that you should never sit, step, or walk on a skylight. They are not designed to support a person’s weight, and doing so can lead to a serious fall and severe injury. There is no repair worth that risk. A professional team has the proper safety equipment and training to work at heights securely, so you don’t have to.

Spotting Complex Structural Issues

Sometimes, a leak isn’t just a simple crack—it’s a symptom of a deeper problem. The issue could be with the flashing, which is the metal material that seals the connection between your skylight and the roof. If the flashing is rusted, bent, or pulled away from the roof, it creates a direct path for water to get in. Similarly, the seals around the skylight can degrade over time due to sun exposure and weather, becoming brittle and ineffective. These are not surface-level fixes. A professional skylight inspection can determine if these core components have failed and need to be replaced for a lasting repair.

How to Maintain Your Temporary Patch

You’ve successfully applied a temporary fix to your leaking skylight—that’s a fantastic first step in protecting your home. But the job isn’t quite done. A temporary patch is a bandage, not a cure. It needs a little attention to make sure it holds up until you can get a professional out to assess the damage. Think of it as a short-term solution that buys you valuable time.

Maintaining your patch involves keeping an eye on it, especially as the weather changes. A quick visual check from the ground or a safe vantage point can tell you if your fix is still secure. You’re looking for any signs that the patch is failing, like peeling tape or a tarp that has shifted. This small amount of upkeep prevents a minor leak from turning into a major headache, protecting your home from further water damage while you arrange for a permanent solution. Remember, the goal is to manage the problem, not ignore it.

Checking Your Fix and Clearing Debris

After you’ve applied your temporary fix, make it a habit to check on it every few days and after any rain or wind. Look for any lifting edges on your tape or tarp and check for new water stains indoors. It’s also important to keep the area around your skylight clear. Sweep away any leaves, twigs, or other debris that might have collected. This buildup can trap moisture against your roof and the patch, which can worsen the original problem. Since faulty or deteriorated flashing is a common culprit for leaks, ensuring that area stays clean helps your temporary solution do its job until a professional roof inspection can identify the root cause.

Preparing for Incoming Weather

If you see rain in the forecast, it’s time to give your temporary patch a once-over. A DIY fix that holds up during a light drizzle might not stand a chance against a heavy downpour or strong winds. Make sure your tarp is still securely weighted down or your plastic sheeting is firmly taped in place. Using high-quality, weather-resistant materials for your patch gives you a better chance of it holding firm. However, always remember that this is a temporary measure. It’s not designed to be a storm-proof shield for your home, so it’s best to be proactive and ensure it’s as secure as possible before bad weather hits.

Scheduling a Permanent Repair

A temporary patch is only meant to last for a short time. The longer you wait to schedule a permanent repair, the greater the risk of more serious issues like mold, wood rot, or structural damage to your roof. Professional roofers use specific, high-grade materials and techniques that a DIY fix can’t replicate. Don’t let a small leak become a costly, whole-roof problem. Once you have the immediate leak under control, your very next step should be to call a professional. Our team at Cert-A-Roof specializes in skylight services and can provide a lasting solution that protects your home for years to come.

Frequently Asked Questions

How long can I really expect a temporary patch to last? A temporary fix is designed to be just that—temporary. Think of it as a reliable bandage that will protect your home for a few days or weeks, giving you enough time to schedule a professional repair. Its lifespan depends on the materials you used and the weather. A strong tarp might hold up through a storm, but it’s not a solution for the entire rainy season. The goal is to stop immediate water damage, not to create a permanent seal.

My skylight is leaking, but I can’t find any obvious cracks in the glass. What could be the problem? This is a very common situation. More often than not, the leak isn’t coming from the skylight’s glass but from the area around it. The problem is likely with the flashing, which is the metal sealing around the skylight’s frame, or the weather seals themselves. Over time, these components can degrade, crack, or pull away from the roof, creating a hidden path for water to get into your home.

Is a very small, slow drip from my skylight really an urgent problem? Yes, you should treat any leak as an urgent issue. That small drip you see is only the water that has made it all the way through your roof and ceiling. Behind the scenes, that moisture could be soaking into your home’s insulation, wooden support beams, and drywall. Leaving it alone can lead to wood rot, mold growth, and much more significant damage down the road.

Why can’t I just use a stronger sealant and make the temporary fix permanent myself? A DIY patch, even a good one, typically only addresses the symptom you can see. A professional roofer is trained to find the root cause of the leak, which might be an issue with how the skylight or its flashing was originally installed. They have access to commercial-grade materials and the expertise to ensure the repair integrates properly with your entire roofing system for a truly permanent, watertight solution.

What is the single most common reason a skylight starts to leak? The most frequent culprit behind a leaky skylight is failing flashing. Flashing is the metal material that directs water away from the skylight and down the roof. If it was installed incorrectly, or if it has become damaged or corroded over the years, it can no longer do its job effectively. This allows water to seep underneath the flashing and into your home, even if the skylight itself is in perfect condition.
