Skylight Leaking When Raining | Five Star Roofing Charlotte

Why Your Skylight Leaks Every Time It Rains in Charlotte

You notice water dripping from skylight during every storm. Charlotte's heavy rainfall patterns expose skylight vulnerabilities faster than in most regions. Our subtropical climate delivers sudden downpours, extended rain events, and humidity that accelerates material breakdown around roof windows.

Most skylight leaking during storm events points to compromised flashing. The metal or rubber seal connecting your skylight to the roof deck fails when improperly installed or degraded by UV exposure. Charlotte's temperature swings from freezing winters to 95-degree summers create expansion and contraction cycles that crack sealant and loosen fasteners.

Water dripping from skylight also signals clogged drainage channels. Leaves from Charlotte's dense tree canopy, particularly oak and pine, accumulate in the skylight curb. When heavy rain hits, water backs up instead of channeling away from the glass unit.

Skylight leaks in heavy rain often originate from roof deck issues beneath the unit. If the decking around your skylight has softened from previous moisture intrusion, the flashing cannot maintain a watertight seal. The problem compounds with each storm until you address both the flashing and underlying structure.

Condensation mimics a roof window leaking. Charlotte's humidity levels average 70 percent year-round. When warm, moist air contacts cold skylight glass, condensation forms and drips. This differs from actual leaking skylight flashing but requires ventilation solutions.

You need diagnosis before repair. Water travels along roof rafters and sheathing before appearing at your ceiling. The visible drip location rarely matches the actual entry point.

How We Fix Skylight Leaks Permanently

We start with roof deck inspection before touching the skylight. Many contractors reseal flashing without checking the substrate. If the deck is compromised, new flashing fails within months. We probe the sheathing around the skylight curb for soft spots, rot, or delamination. Compromised deck sections get replaced with exterior-grade plywood before flashing work begins.

Our flashing replacement uses step flashing integrated with your roofing material. We remove the skylight unit, install new underlayment extending 12 inches beyond the opening, then rebuild the curb with treated lumber if needed. The flashing system layers from bottom to top, with each piece overlapping the one below. This creates multiple barriers against water intrusion.

For flat skylights common in modern Charlotte homes, we install a cricket or saddle behind the unit. This small ridge diverts water around the skylight instead of letting it pool against the uphill flashing. Most leaking skylight flashing failures happen on the high side where water pressure is greatest during heavy rain.

We address drainage before reinstalling your skylight. The weep holes in the skylight curb must stay clear. We clean existing channels, add debris guards, and verify water exits the system during our hose test. Blocked drainage causes 40 percent of skylight leaks in heavy rain.

Sealant application follows manufacturer specifications for your skylight brand. Different manufacturers require different products. Using generic silicone on a Velux skylight voids any remaining warranty and fails prematurely. We stock brand-specific sealants and apply them only where required, not as a substitute for proper flashing.

Our final inspection includes interior examination. We check your attic for water stains, measure moisture levels in surrounding insulation, and document the roof deck condition. This baseline helps you track performance after our repair.

What Happens During Your Skylight Leak Repair

Initial Leak Assessment

We inspect your skylight from interior and exterior positions. Inside, we trace water stains across ceiling joists to find the entry point. Outside, we examine flashing condition, sealant integrity, and roof deck soundness. We test drainage channels and check for debris accumulation. This dual-perspective assessment identifies whether you have a flashing failure, condensation issue, or structural problem requiring deck replacement before any cosmetic repairs begin.

Flashing Reconstruction

We remove your skylight unit and existing flashing system. Any compromised decking gets replaced with new sheathing. We install Ice and Water Shield underlayment around the opening, then build the step flashing from bottom to top. Each piece integrates with your shingle courses, creating a continuous water barrier. For skylights on low-slope sections, we add a cricket to divert water flow. The skylight reinstalls with manufacturer-specified sealants applied only at designated points.

Performance Testing

We conduct a controlled water test before leaving your property. Using a hose, we simulate heavy rain conditions while monitoring for leaks from inside your attic. We verify drainage channels evacuate water properly and check that all flashing layers shed water as designed. You receive documentation of the testing process, photos of the completed installation, and guidance on what to monitor during future rain events to ensure your skylight performs correctly.

Frequently Asked Questions

You Have Questions,
We Have Answers

Why is my skylight leaking in heavy rain? +

Heavy rain exposes weak points in skylight installation. The most common culprits are degraded flashing around the curb, failed sealant at the glazing, or improper installation that allows water to pool. Charlotte's intense summer storms can drive rain sideways under poorly integrated flashing. Clogged gutters or debris buildup around the skylight can also divert water into vulnerable seams. If you see water stains on the ceiling or drips during downpours, the flashing or seals have likely failed. This is not normal and requires immediate inspection before moisture damages your decking or insulation.

How to fix a skylight that is leaking? +

Fixing a leaking skylight starts with identifying the source. Inspect the flashing first. If metal flashing is loose, corroded, or improperly layered with shingles, it must be removed and reinstalled correctly. Check the glazing seals for cracks or gaps. Reapply exterior-grade sealant if deteriorated. Clear debris from the uphill side where water flows around the unit. Charlotte's clay soil can cause roof deck shifting, which stresses skylight mounts. If the leak persists or the curb is damaged, full replacement may be necessary. A professional inspection pinpoints the exact failure point and prevents guesswork.

Can skylights be resealed? +

Yes, skylights can be resealed if the glazing unit and curb remain structurally sound. Remove old, cracked sealant completely using a scraper. Clean surfaces with isopropyl alcohol. Apply a continuous bead of polyurethane or silicone sealant rated for exterior use and UV exposure. This works for minor seal degradation. However, if flashing has failed or the curb has rotted from prolonged moisture exposure, resealing alone will not stop leaks. Charlotte's humidity accelerates wood decay, so inspect the curb carefully. Resealing is a temporary fix if underlying structural issues exist. Professional assessment ensures you address the root cause.

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

No, it is not normal for a roof to leak in heavy rain. A properly installed roof with intact flashing, underlayment, and shingles should keep water out regardless of storm intensity. Leaks indicate a failure point such as damaged flashing around penetrations like skylights or vents, missing shingles, or deteriorated underlayment. Charlotte's frequent thunderstorms and wind-driven rain test every vulnerable seam. If your roof leaks only during heavy downpours, wind may be lifting shingles or pushing water under compromised flashing. Address leaks immediately. Prolonged water intrusion damages sheathing, insulation, and framing, leading to costly repairs.

Does homeowners insurance cover roof leaks from rain? +

Homeowners insurance typically covers sudden roof leaks caused by covered perils like wind damage or falling trees. However, leaks resulting from wear, aging, or deferred maintenance are usually excluded. If a storm damages your skylight flashing and causes a leak, you may have coverage. Gradual seal failure or improper installation is not covered. Document the damage with photos and contact your insurer promptly. Charlotte's severe weather can complicate claims if you cannot prove storm damage versus neglect. Review your policy and deductible. An inspection report identifying storm damage strengthens your claim if the leak appears after a weather event.

How much does it cost to fix a leaky skylight? +

Repair costs vary based on the damage extent. Resealing glazing or replacing deteriorated sealant may run a few hundred dollars. Reflashing a skylight typically costs more due to labor and materials for proper integration with surrounding shingles. If the curb or decking has rotted from prolonged leaks, structural repairs increase costs. Full skylight replacement, including removal, new flashing, and installation, is the highest expense. Charlotte's high humidity and frequent storms can accelerate damage if leaks go unaddressed. A professional inspection identifies the scope of work. Delaying repairs worsens damage and raises costs as moisture spreads through decking and insulation.

What is the most common cause of skylight leaks? +

Faulty or deteriorated flashing causes most skylight leaks. Flashing creates a watertight seal between the skylight curb and roof surface. If improperly installed, corroded, or separated from the shingles, water infiltrates during rain. Installers must layer flashing correctly with step flashing and counter flashing to direct water away. Charlotte's climate accelerates metal corrosion and sealant breakdown. Debris buildup around the skylight can also trap moisture and force water under flashing. Even minor gaps allow water entry. Flashing failure often appears as ceiling stains on the downhill side of the skylight. Proper flashing installation is critical during skylight replacement or roof work.

Do all skylights eventually leak? +

No, not all skylights eventually leak. Properly installed skylights with quality flashing and regular maintenance can last decades without leaks. Failure occurs when installation shortcuts are taken, inferior materials are used, or maintenance is neglected. Charlotte's weather stresses skylights through UV exposure, thermal cycling, and heavy rain. Inspect seals and flashing annually. Clear debris that traps moisture. Replace sealant when cracks appear. Skylights installed during roof replacement with integrated flashing perform better than retrofitted units. Quality materials and professional installation reduce leak risk significantly. Neglect guarantees eventual failure, but proactive care prevents most leaks from developing.

What is the best sealant for a leaking skylight? +

Polyurethane or silicone sealant rated for exterior roofing use works best for skylight leaks. Choose products designed for UV resistance and temperature fluctuations. Polyurethane bonds well to metal and wood, making it ideal for flashing and curb repairs. Silicone remains flexible in Charlotte's heat and cold cycles. Avoid generic caulk, which degrades quickly under UV exposure. Clean all surfaces thoroughly before application. Remove old, failed sealant completely. Apply a continuous bead without gaps. However, sealant is only effective for minor seal degradation. If flashing has failed or structural damage exists, sealant alone will not stop leaks. Professional repair addresses underlying issues.

What is the average lifespan of a skylight? +

Skylights typically last 15 to 25 years depending on materials, installation quality, and maintenance. Acrylic domes may yellow or crack sooner in Charlotte's intense sun. Tempered or laminated glass units last longer with proper care. Flashing and seals degrade faster than the glazing itself. Metal flashing corrodes, sealant cracks, and gaskets harden over time. Charlotte's humidity and UV exposure accelerate material breakdown. Regular inspections extend lifespan by catching small issues early. If your skylight is over 20 years old and leaking, replacement often makes more sense than repeated repairs. New units offer better energy efficiency and warranties against future leaks.
