Skylight Leaking When Raining | First Choice Roofing Atlanta

Why Your Skylight Leaks Every Time It Rains in Atlanta

You hear the patter of rain on the roof. Then you notice the drip. Water is running down the wall beneath your skylight, staining the ceiling and pooling on the floor. This is not random. Skylight leaks in heavy rain point to specific failures in the waterproofing system, and Atlanta's climate makes these failures worse.

Atlanta receives over 50 inches of rain per year, often delivered in sudden downpours with wind-driven rain that tests every seam and joint. When a skylight leaking during storm conditions happens, the water is not coming through the glass. The leak is happening at the flashing, the curb, or the seal where the skylight meets your roof deck.

Most skylight leaks trace back to three root causes. First, the step flashing that channels water around the skylight curb may be missing, corroded, or improperly installed. Second, the counter flashing, which covers the step flashing and prevents water from running behind it, may have failed. Third, the sealant or gasket between the skylight frame and the curb may have degraded from UV exposure and thermal cycling.

Atlanta's summer heat accelerates sealant breakdown. The freeze-thaw cycles we experience in winter cause metal flashing to expand and contract, loosening fasteners and opening gaps. When a roof window leaking occurs, water finds the path of least resistance and follows it straight into your attic insulation and ceiling drywall. Ignoring a water dripping from skylight problem leads to mold growth, insulation damage, and structural rot. The longer you wait, the more expensive the fix becomes.

How We Stop Skylight Leaks Permanently

Most roofers slap caulk around the skylight and call it a day. That fix lasts six months. We take a different approach because leaking skylight flashing requires a methodical repair, not a Band-Aid.

We start with a water test. We simulate rain conditions using controlled water flow to trace the exact entry point. This tells us whether the leak is at the head flashing, the side step flashing, the sill flashing, or the skylight seal itself. We do not guess.

Once we identify the source, we remove the failed components. If the step flashing is compromised, we lift the shingles around the skylight curb, remove the old flashing, and install new corrosion-resistant metal flashing with proper overlap and fastener placement. Each piece of step flashing must be woven into the shingle courses and lapped under the counter flashing. This creates a continuous water barrier that directs moisture away from the curb.

If the counter flashing has failed, we replace it with new material and seal it with high-grade polyurethane or butyl sealant rated for UV exposure and thermal movement. If the skylight curb itself is rotted, we rebuild it with pressure-treated lumber and apply ice and water shield before reinstalling the skylight.

We also inspect the skylight glazing and gaskets. If the unit is old and the seals are brittle, we replace the entire skylight. Trying to save a 20-year-old skylight with failed seals is false economy. You will pay twice.

First Choice Roofing Atlanta does not take shortcuts. We follow manufacturer installation specs and integrate the skylight into your roof's drainage plane. When we finish, the skylight sheds water like it was designed to.

Skylight Leaking When Raining in Atlanta – Expert Diagnosis and Permanent Waterproofing

Leak Source Identification

We inspect the skylight from both the interior and the roof deck. We check the flashing, the curb, the shingle integration, and the seal. We perform a controlled water test to confirm the exact entry point. This step eliminates guesswork and ensures we repair the actual problem, not just the visible symptom.

Flashing and Seal Repair

We remove the failed flashing and install new step flashing and counter flashing with proper lapping and fastener placement. We replace degraded sealant with high-grade materials rated for thermal movement and UV exposure. If the curb is damaged, we rebuild it with pressure-treated lumber and apply ice and water shield for added protection.

Final Water Test and Inspection

After completing the repair, we run another water test to confirm the leak is resolved. We inspect the interior ceiling for moisture and document the repair with photos. You receive a detailed report explaining what we fixed and why. The skylight is now integrated into your roof's waterproofing system and ready for the next storm.

Skylight leaks are not a DIY project. They require an understanding of roof drainage, flashing details, and how water moves across a roof deck. We have been diagnosing and repairing skylight leaks across Atlanta for years, and we understand how local weather patterns stress these vulnerable roof penetrations.

Atlanta's intense summer thunderstorms deliver high-volume rainfall in short bursts. Wind-driven rain hits the skylight from the side, testing the integrity of the flashing and seals. Our repairs account for these conditions. We use materials rated for Georgia's climate and install flashing that channels water away from the curb, even under extreme conditions.

We also understand Atlanta's building stock. Many homes in neighborhoods like Virginia Highland, Druid Hills, and Candler Park have original skylights that are decades old. These older units were often installed without proper flashing or with materials that have long since degraded. We have seen every type of skylight installation mistake, and we know how to correct them.

When you work with First Choice Roofing Atlanta, you get a crew that understands the difference between a temporary patch and a permanent fix. We do not use excessive caulk or cheap sealant. We install metal flashing, integrate it into the shingle courses, and ensure the skylight functions as part of the roof system.

We also know Atlanta's permit and code requirements. If your skylight replacement requires a permit, we handle the paperwork and ensure the work meets current building standards. You do not have to worry about compliance issues down the line.

Choosing a local roofer who understands Atlanta's weather and building characteristics means you get a repair that lasts. We stand behind our work because we do it right the first time.

What You Can Expect When We Fix Your Leaking Skylight

Fast Response and Scheduling

We understand that a skylight leaking when raining is not just an inconvenience. It is active water damage happening inside your home. We respond to service requests quickly and schedule inspections within days, not weeks. During storm season, we prioritize emergency leaks to minimize interior damage. Once we identify the problem, we provide a clear timeline for the repair and work around your schedule to complete the job efficiently.

Thorough Inspection and Diagnosis

Our inspection is not a five-minute glance from a ladder. We access the roof deck, examine the flashing from above and below, and check the skylight curb for rot. We test the seal integrity and look for signs of previous failed repairs. We also inspect the surrounding shingles for damage that could contribute to water intrusion. You receive a detailed explanation of what is causing the leak and what needs to be done to fix it permanently.

Quality Materials and Workmanship

We use corrosion-resistant metal flashing, high-grade sealants rated for thermal cycling, and ice and water shield at critical areas. We do not use tar or low-grade caulk. Every piece of flashing is installed with the correct overlap, fastener spacing, and integration into the shingle courses. The repair is designed to last as long as your roof. You will not see us back in six months because the patch failed.

Documentation and Follow-Up

After we complete the repair, we document the work with photos and provide you with a written summary of what was done. If we replaced flashing or rebuilt the curb, you receive a record of the materials used and the installation details. We also offer guidance on skylight maintenance and what to watch for in the future. If you have any concerns after the repair, we are available to answer questions and provide follow-up inspections.

Frequently Asked Questions

You Have Questions,
We Have Answers

Why is my skylight leaking in heavy rain? +

Your skylight leaks in heavy rain because water finds weak points around the flashing or seal. Atlanta's intense summer storms test every junction where the skylight meets your roof. Failed flashing is the most common culprit. The metal strips that connect the skylight to your shingles crack, separate, or corrode over time. Clogged gutters force water backup under the flashing. Improper installation during the original build also causes problems. The skylight curb may sit incorrectly, or the installer skipped critical waterproofing steps. High humidity here accelerates sealant degradation faster than drier climates.

How to fix a skylight that is leaking? +

Fixing a leaking skylight starts with identifying the exact failure point. Check the flashing first. You need to remove shingles around the skylight frame and inspect metal flashing for gaps, rust, or separation. Replace damaged flashing completely. Do not patch it. Next, examine the skylight dome for cracks. Small cracks need professional replacement. Check the interior seal where glass meets the frame. If debris clogs your gutters, clean them to prevent water backup. Atlanta's clay soil shifts foundations over time, which can torque skylight frames and break seals. Address this structural movement before resealing.

Can skylights be resealed? +

Yes, skylights can be resealed, but only if the frame and glass are intact. Remove old caulk completely using a scraper. Clean all surfaces with denatured alcohol to remove residue. Apply a high-grade polyurethane or silicone sealant rated for exterior use and UV resistance. Atlanta's sun degrades cheap sealants quickly. Press the bead firmly into the joint. Do not just lay it on top. Resealing works for minor deterioration. If your flashing is compromised or the curb is rotted, resealing alone will not stop the leak. You need structural repairs first. Resealing is a temporary fix, not a permanent solution.

Is it normal for a roof to leak in heavy rain? +

No, roof leaks in heavy rain are not normal. A properly installed and maintained roof should keep water out during any storm. If your roof leaks only during heavy Atlanta downpours, you have a defect. Common causes include missing shingles, failed valley flashing, or improper slope around chimneys and vents. Wind-driven rain exposes weak spots that light rain misses. Age matters. Roofs over 15 years old lose granule protection, and underlayment deteriorates. Ice dams are rare here, but our high humidity and temperature swings cause shingle expansion and contraction that opens seams. Find the leak source immediately before water damages your decking.

How Atlanta's Storm Patterns and Roof Types Make Skylight Leaks More Common

Atlanta receives frequent thunderstorms between March and September, often with intense rainfall rates exceeding two inches per hour. This high-volume, wind-driven rain overwhelms poorly flashed skylights and exposes installation defects. Many Atlanta homes have asphalt shingle roofs with moderate slopes, which means water moves across the roof deck more slowly than on steeper pitches. This gives water more time to find gaps in the flashing and work its way under the counter flashing or through failed sealant. Homes in older neighborhoods often have skylights installed before modern flashing standards were adopted, making them especially vulnerable during storm season.

First Choice Roofing Atlanta has worked on hundreds of skylight repairs across the metro area, from Buckhead to Decatur to Marietta. We understand the roof construction methods common to Atlanta's residential building stock and we know how to integrate skylight flashing into both new and older roof assemblies. Our team stays current on Georgia building codes and manufacturer installation requirements. When you hire a local crew with Atlanta-specific experience, you get a repair that accounts for the weather, the roof type, and the building standards that matter here.
