Our Skylight Window Leak Repair Services

We focus on careful inspection, accurate diagnosis, and safe repairs to fix skylight leaks quickly. Our approach uses tested methods and tools to ensure lasting results and protect your home from water damage.

Window Repair

Our repair process starts with a full inspection of the skylight and surrounding roof. We check for cracks, sealant damage, and flashing problems. After finding the leak source, we remove old sealant and debris.


We then apply high-quality sealants designed for skylights. These sealants are waterproof and flexible to handle temperature changes. If any parts, like flashing or glass panes, need replacement, we handle that too.


Once the repair is complete, we test the skylight by spraying water over it. This ensures the leak is fully fixed before we finish the job.

Leak Detection

To find leaks, we use both visual checks and specialized tools. We inspect the skylight frame, glass, and flashing for signs of wear or gaps. Looking for discoloration or damp spots helps us spot hidden leaks.


We often use moisture meters to detect trapped water inside the skylight structure. Infrared cameras help us see temperature differences that may indicate water presence behind walls or roof materials.


These tools allow us to find even small leaks early. That helps prevent bigger damage before it happens.

Safety Practices

Safety is a top priority for us. Working on skylights usually means climbing ladders or accessing roofs. We use harnesses and fall protection gear to protect our team.


Before starting repairs, we check weather conditions to avoid slippery surfaces or storms. We also protect your property by placing drop cloths and covering nearby plants or furniture.


Our team follows local safety codes and uses tools designed for roof work. This keeps both workers and your home safe throughout the repair process.

Our Skylight Window Resealing Solutions

Types of Resealing Materials

We use a variety of materials depending on the skylight’s needs. Common options include silicone sealants, which are flexible and water-resistant, and polyurethane sealants, known for their strong adhesion and durability. Weatherproof butyl tape is another option for quick fixes or added layers of protection.


Each material has unique properties. Silicone is great for UV resistance, while polyurethane handles expansion and contraction well. Choosing the right sealant depends on the window frame, roof type, and weather exposure.

Resealing for Prevention

Regular inspection and maintenance help us spot potential issues early. We recommend resealing every 5 years or sooner if you notice cracking or shrinking.


We also pay attention to the skylight’s flashing and drainage paths. Keeping these clear from debris and ensuring sealant overlaps flashing correctly helps prevent water buildup. Proper resealing creates a tight barrier that stops leaks before they start.

Best Practices for Lasting Results

Before applying any sealant, we clean the surface thoroughly to remove dirt and old sealant. Clear, even application is key. We apply the sealant in layers, ensuring no gaps or bubbles.


We also check for any damage around the flashing or frame that could compromise sealing. Proper curing time is important, so we avoid rushing the repair. This reduces the risk of cracking or peeling later on.

Maintenance Tips After Skylight Leak Repairs

After we fix a skylight leak, it is important to keep an eye on it. Regular checks help us avoid new problems. We suggest inspecting the skylight at least twice a year.


We recommend cleaning the skylight glass and frame gently. Use mild soap and water to remove dirt and prevent buildup. Avoid harsh chemicals that can damage the seals.


Checking the seals and flashing around the skylight is also important. If we notice cracks or wear, we should reseal or call for professional help. This keeps water out and maintains the fix.


We also advise keeping gutters clean near skylights. Blocked gutters can cause water to pool and lead to leaks. Make sure water flows freely away from the skylight.


If we notice any leaks or damage after maintenance, it's best to contact our repair team right away. Early action prevents bigger issues and expenses later on.

Skylight Window Leak Repair and Resealing FAQs

  • What are the common signs indicating a skylight window needs repair or resealing?

    Water stains or damp spots on the ceiling near the skylight show leaks. Condensation buildup or drafts around the window frame also point to seal failure. Cracks or damage to the skylight glass or frame can need repair to stop leaks.

  • How can I determine if a leak is due to the skylight or another issue with my roof?

    Check if water appears only under the skylight during rain. Inspect the roof area around the skylight for missing shingles or damage.


    A test with water poured on the roof above the skylight can help isolate the leak source.

  • What materials are used for resealing a skylight window to ensure it is weatherproof?

    We use high-quality silicone or polyurethane sealants designed for outdoor use. Flashing tape and metal flashing are added to improve waterproofing around the skylight frame.

  • How often should skylight windows be inspected to prevent leaks?

    We recommend inspections at least once a year. After heavy storms or extreme weather, checking the skylight again is wise.

  • Are there energy-efficient options for skylight window repairs that also help reduce heating costs?

    Replacing old seals with better insulating materials can improve energy efficiency. Upgrading to double-glazed or low-E glass helps reduce heat loss.
