Why Your Skylight Leaks During Miami's Heavy Rain Events

You notice water dripping from skylight edges during afternoon thunderstorms. The ceiling around your roof window shows brownish stains. The problem gets worse when wind-driven rain hammers your home from the east.

Miami's intense rainfall and high humidity create brutal conditions for skylights. A typical summer storm dumps two inches of rain in under an hour. Wind speeds hit 40 mph. Water finds every microscopic gap in your skylight flashing.

Most skylight leaking during storm events traces back to three issues. Failed flashing around the skylight curb allows water to bypass the waterproof membrane. Cracked or deteriorated sealant lets moisture penetrate at vulnerable seams. Improper installation from the beginning creates a system that never worked correctly.

The subtropical climate accelerates the breakdown. UV radiation degrades rubber gaskets and silicone seals. Thermal expansion from 90-degree heat cycles stresses metal flashing. Salt air from Biscayne Bay corrodes aluminum components. Your skylight weathers conditions that skylights in Denver or Seattle never face.

Roof window leaking worsens over time. That small drip during heavy rain becomes a steady stream. Water tracks along roof decking and damages insulation. Mold grows in wall cavities within 48 hours in Miami's humidity. The longer you wait, the more expensive the fix becomes.

Skylight leaks in heavy rain need professional diagnosis. The visible leak inside your home rarely sits directly below the actual failure point. Water travels along roof sheathing before dripping through your ceiling. You need someone who understands roof geometry and water flow patterns to locate the true source.

Why Your Skylight Leaks During Miami's Heavy Rain Events
How We Diagnose and Repair Leaking Skylight Flashing

How We Diagnose and Repair Leaking Skylight Flashing

We start with a detailed roof inspection during dry conditions. Leaks hide when the sun shines. We examine the skylight curb where it penetrates your roof deck. We check step flashing integration with your shingle courses. We inspect the head flashing that diverts water around the top edge of the skylight.

Most roofers miss the counterflashing detail. This metal component sits between your skylight frame and the roofing underlayment. When counterflashing fails, water migrates under shingles and soaks your decking. We remove shingles around the skylight perimeter to expose the complete flashing system. You cannot fix what you cannot see.

We test sealant adhesion at every joint. Old silicone peels away from glass and metal surfaces. We verify that weep holes in the skylight frame drain properly. Clogged weep holes cause water to back up and overflow into your home. We check the condition of your roof deck for soft spots that indicate long-term moisture damage.

The repair approach depends on what we find. Minor failures get spot repairs with proper flashing tape and polyurethane sealant rated for Miami's temperature swings. Widespread deterioration requires complete reflashing using ice and water shield underlayment. We integrate new step flashing that laps correctly with each shingle course. We install kick-out flashing at the bottom corners where water volume concentrates.

Severe cases need skylight replacement. A 20-year-old skylight with cracked acrylic and corroded frames cannot be saved with new flashing. We remove the old unit, repair damaged decking, install a proper curb system, and flash the new skylight according to manufacturer specifications and Miami-Dade building code.

We never use roof cement or generic caulk. These products fail in UV exposure and thermal cycling. We use compatible materials engineered for permanent waterproofing.

What Happens During Your Skylight Leak Repair

Skylight Leaking When Raining in Miami | Expert Diagnosis and Permanent Repairs
01

Roof and Attic Inspection

We examine your skylight from above and below. The roof inspection identifies flashing failures, sealant gaps, and shingle integration problems. The attic inspection reveals water staining patterns on decking and framing. We trace the leak path from where water enters to where it drips into your living space. This dual approach pinpoints the exact failure point.
02

Flashing System Repair

We remove damaged shingles around your skylight and expose the existing flashing. Failed components get replaced with new step flashing, counterflashing, and head flashing. We apply ice and water shield underlayment that self-seals around fastener penetrations. New shingles integrate with the flashing system in proper lapping sequence. Every seam gets sealed with polyurethane designed for metal-to-shingle adhesion.
03

Water Test and Verification

We simulate rainfall conditions with controlled water application. A garden hose directs water at the skylight from multiple angles and volumes. We monitor the attic space for any moisture penetration. The test runs for 15 minutes minimum, matching the intensity of a typical Miami thunderstorm. You get confirmation that the repair works before we leave your property.

Why Miami Homeowners Trust Our Skylight Expertise

We understand how Miami's weather attacks skylights. The combination of intense UV exposure, salt air, and violent thunderstorms creates failure modes you do not see in other climates. A roofer from Atlanta or Charlotte does not know these conditions.

Miami-Dade County requires high-velocity hurricane zone compliance for all roof penetrations. Your skylight installation must meet specific wind load and water intrusion standards. We know the product approval list. We know which skylights carry valid NOAs for this jurisdiction. We install systems that pass inspection.

Ironwood Roofing Miami has repaired hundreds of leaking skylights across Coral Gables, Coconut Grove, and Pinecrest. We know the common installation mistakes made during the building boom. We have seen every skylight brand and model installed in South Florida over the past 30 years. This experience means we diagnose problems faster and fix them correctly the first time.

We do not subcontract skylight work to generalists. Our crew members specialize in complex flashing details and roof penetrations. They understand how water moves across tile, shingle, and flat roof assemblies. They carry the tools and materials needed for proper repairs, not improvised solutions with whatever sits on the truck.

You get written documentation of what failed and how we fixed it. The report includes photos of damaged components before repair and the completed installation after repair. This documentation helps if you file an insurance claim. It provides a baseline for future roof inspections.

We repair skylights on all roof types common to Miami. Concrete tile, asphalt shingle, clay barrel tile, and modified bitumen flat roofs all require different flashing approaches. The waterproofing principles stay the same, but the execution details change based on your roof assembly.

What to Expect from Your Skylight Leak Repair

Fast Response During Leak Emergencies

Active skylight leaking during storm events gets priority scheduling. We understand that water damage accelerates in humid conditions. Mold starts growing within two days. We dispatch crews within 24 hours for emergency leak calls. If weather permits safe roof access, we can provide temporary waterproofing with tarps and emergency sealant while we order materials for permanent repair. Most skylight leak repairs complete in one day once we start work. Complex jobs requiring skylight replacement may take two days depending on custom curb fabrication needs.

Thorough Leak Source Identification

The visible water stain on your ceiling does not reveal where the leak originates. Water travels horizontally along roof sheathing before dripping through drywall. We perform systematic inspection of all skylight components. This includes examining the glass or acrylic dome for cracks, checking weep hole function, testing sealant adhesion at the frame perimeter, and exposing flashing layers under surrounding shingles. We identify the actual failure point, not just treat symptoms. You get an honest assessment of whether repair or replacement makes sense based on skylight age and condition.

Permanent Waterproofing Solutions

We install flashing systems engineered for Miami's weather extremes. Ice and water shield underlayment provides backup protection even if primary flashing fails. Step flashing integrates with shingle courses in proper lapping sequence. Counterflashing diverts water away from the skylight curb. All sealants carry UV resistance and flexibility ratings for temperature cycling from 65 to 95 degrees. The materials match or exceed the lifespan of your roof system. You get repairs built to survive the next 15 to 20 years of hurricanes and thunderstorms, not temporary patches that fail in the next heavy rain.

Post-Repair Documentation and Support

You receive detailed photos showing the condition before repair and the completed installation. The documentation identifies what components we replaced and what materials we used. This record helps with insurance claims and adds value during home sales. We provide maintenance recommendations specific to your skylight type. Some skylights need annual gasket inspection and sealant touch-up. Others require weep hole cleaning after major storms. We offer annual roof inspection services that include skylight condition assessment. Catching small problems early prevents major leaks later.

Frequently Asked Questions

You Have Questions,
We Have Answers

Why is my skylight leaking in heavy rain? +

Heavy rain exposes weak points in your skylight system. The most common culprits are cracked or missing flashing around the skylight curb, deteriorated sealant at the glass edges, or improperly installed step flashing. In Miami, intense afternoon thunderstorms and hurricane-force rain drive water horizontally, not just downward. This sideways pressure finds any gap in the flashing or weatherproofing. Condensation inside the skylight shaft can also mimic a leak during humid downpours. A professional inspection identifies whether the issue is flashing failure, sealant breakdown, or structural movement in the roof deck.

Is a leaking skylight covered by homeowners insurance? +

Coverage depends on the cause of the leak. If a covered peril like a hurricane or windstorm damaged the skylight or surrounding flashing, your homeowners policy typically covers repairs. However, if the leak results from gradual wear, poor maintenance, or improper installation, insurers often deny the claim. Miami policies scrutinize storm damage claims closely due to frequent tropical weather. Document the leak immediately with photos and contact your insurer quickly. Many policies require prompt reporting. A roofing contractor can provide a damage assessment that clarifies whether the failure stems from a sudden event or long-term neglect.

How to fix a skylight that is leaking? +

Fixing a leaking skylight starts with identifying the exact failure point. Remove interior trim and check for moisture stains that trace back to the source. Most leaks originate at the flashing, where metal meets roofing material. Replace damaged step flashing and counter flashing, ensuring proper overlap and integration with underlayment. Reseal the skylight curb with high-grade polyurethane or butyl rubber sealant, not silicone. In Miami, UV exposure and thermal expansion break down inferior sealants quickly. If the skylight glass is cracked or the dome is foggy, full replacement may be necessary. Always address surrounding shingle damage to prevent future water infiltration.

Can skylights be resealed? +

Yes, skylights can be resealed if the glass and frame remain structurally sound. Remove old, cracked sealant completely using a plastic scraper and solvent. Clean all surfaces thoroughly before applying a fresh bead of exterior-grade polyurethane or butyl sealant around the glass perimeter and curb joints. In Miami, choose UV-resistant products rated for tropical climates. Resealing only works if the flashing is intact and the skylight frame has not warped. If you see rust, rot, or significant gaps, resealing is a temporary fix. Persistent leaks after resealing usually indicate flashing failure or structural issues requiring professional intervention.

Does homeowners insurance cover roof leaks from storms? +

Homeowners insurance typically covers storm-related roof leaks if wind, hail, or falling debris caused the damage. In Miami, hurricane and tropical storm damage falls under wind coverage, but you must prove the leak resulted from a sudden event, not gradual deterioration. Policies exclude maintenance-related issues like worn shingles or aging flashing. After a storm, document damage immediately with photos and videos. File your claim within the timeframe specified in your policy. Some Miami insurers require separate windstorm or hurricane deductibles. A professional roof inspection report strengthens your claim by linking the leak directly to storm damage.

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

Skylight leak repairs in Miami range widely based on the problem. Simple resealing or flashing repairs may cost a few hundred dollars. Replacing damaged flashing, underlayment, and surrounding shingles typically runs higher. Full skylight replacement, including removing the old unit, installing new flashing, and integrating with your roof system, costs significantly more. Flat or low-slope roofs common in Miami commercial buildings require specialized flashing systems that increase labor costs. Age of the skylight, accessibility, and roof type all affect pricing. Request a detailed inspection to identify the root cause before committing to repairs.

Who is the best person to fix a leaking roof? +

A licensed roofing contractor is the best professional to fix a leaking roof in Miami. Roofers understand flashing, underlayment, and how water moves across different roof slopes. They identify hidden damage that causes leaks, not just surface symptoms. Choose a contractor familiar with Miami's building codes, high-wind requirements, and common architectural styles. Verify their license with the state and confirm they carry liability insurance and workers compensation. Avoid handymen for structural roof work. A qualified roofer provides a written diagnosis, explains repair options, and warranties their work. Experience with Florida's tropical climate and storm damage is essential.

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

No, a properly installed and maintained roof should not leak during heavy rain. If water enters your home during storms, something has failed. Common causes include missing or damaged shingles, deteriorated flashing around chimneys or skylights, clogged gutters forcing water under roof edges, or improper valley installation. Miami's intense afternoon thunderstorms and horizontal rain test every weak point. Even small gaps in flashing or worn sealant become entry points. A leak signals immediate attention is needed. Ignoring it leads to rotted decking, mold growth, and interior damage. Schedule a professional inspection to locate and repair the failure.

Can you file an insurance claim for a leaky roof? +

Yes, you can file an insurance claim for a leaky roof if the damage resulted from a covered peril like wind, hail, or falling trees. In Miami, hurricane and tropical storm damage qualifies under wind coverage. Document the leak with photos and videos showing both interior damage and exterior roof conditions. Contact your insurer immediately, as policies require prompt reporting. An adjuster will inspect and determine coverage. If the leak stems from normal wear, poor maintenance, or gradual deterioration, the claim will likely be denied. A professional roofing inspection report helps establish the cause and supports your claim.

Do all skylights eventually leak? +

No, properly installed skylights with quality flashing and regular maintenance should not leak. However, Miami's harsh UV exposure, high humidity, and intense storms accelerate sealant breakdown and flashing deterioration. Skylights require periodic inspection and maintenance, including checking sealant integrity, clearing debris from the curb, and ensuring flashing remains secure. Cheap skylights or poor installation often fail within years. Quality units with metal flashing systems and proper integration into the roof assembly last decades without leaks. The key is proactive maintenance. Inspect your skylight annually and reseal as needed. Ignoring maintenance turns a preventable issue into expensive water damage.

How Miami's Afternoon Thunderstorms Test Skylight Waterproofing

Miami receives 62 inches of rainfall annually, with most falling during violent afternoon thunderstorms between June and September. These storms produce two to three inches of rain in under an hour with wind gusts exceeding 40 mph. Wind-driven rain hits skylights horizontally, forcing water past flashing details that work fine in gentle vertical rainfall. The combination of high water volume and lateral pressure finds every gap in deteriorated sealant or improperly lapped flashing. Your skylight must handle conditions far more severe than the gentle rain that skylights in Phoenix or Los Angeles ever face.

Miami-Dade County enforces strict building codes for roof penetrations in high-velocity hurricane zones. All skylight installations require product approval notices and specific flashing details. Ironwood Roofing Miami stays current on code requirements and approved product lists. We know which inspectors cover which areas and what details they scrutinize. Our installations pass inspection the first time because we follow the code exactly. This local knowledge matters when you need repairs that meet legal standards for hurricane protection and water intrusion prevention.
