Skylight Replacement in Florida: Brighten Your Home Without the Leaks ☀️
☀️ Introduction
A skylight can transform your Florida home with natural light, but if the unit is outdated or cracked, you risk dreaded ceiling stains and water drips each time it rains. With Florida’s sideways storms and hot sun, skylights must handle high wind-uplift, intense UV, and potential debris impacts. So what are your replacement options? Some homeowners pick tubular skylights for small spaces, while others want large impact-resistant glass that wards off hurricanes. In this blog, we’ll break down the best skylight replacement solutions for Florida, from basic curb-mount designs to advanced solar-powered vents. Whether you want to preserve that beam of sunshine or stop an ongoing leak, we’ll help you find a modern skylight that brightens your home—without inviting the elements inside.
1. Signs You Need a Skylight Replacement
Aging skylights in Florida often show these telltale issues:
- Persistent Leaks: Water stains around the skylight’s trim, dripping during typical Florida thunderstorms. Re-sealing or replacing gaskets no longer helps.
- Cloudy or Hazy Lens: Acrylic domes might turn milky from UV exposure. Insulated glass units can lose their seal, fogging up.
- Cracked Frames or Gaskets: The intense Florida sun bakes rubber gaskets, while salt air can corrode metal frames. If cracks spread, a patch fix rarely lasts.
- Poor Energy Efficiency: Older skylights lacking double-pane or Low-E coatings can heat up your interior drastically. In Florida’s climate, this spikes AC usage.
Occasionally, a short-term fix—like re-flashing the curb or applying fresh sealant—can buy time, but if the lens or frame is damaged, you’re better off
upgrading. Florida storms only exploit small cracks or worn-out seals. By switching to a new, high-performance skylight, you effectively close off those infiltration points while capturing bright, UV-filtered light that’s easier on AC bills.
2. Impact-Resistant Glass vs. Acrylic Domes
In a hurricane-prone state, impact-resistant glass skylights often shine as the best bet. Compare them to traditional acrylic domes:
- Impact Glass Skylights:
- Pros: Built with laminated glass layers, tested to handle wind-borne debris. Some carry Miami-Dade or Florida Product Approvals, verifying strong storm performance. Clearer view, better insulation.
- Cons: Higher cost upfront. Heavier than acrylic, so curb mounting must handle the load.
- Acrylic (or Polycarbonate) Domes:
- Pros: Lightweight, cheaper, simpler to install. Domed shape can encourage better run-off.
- Cons: Susceptible to cracking under hail or debris. Fogs over time from UV. Typically not code-approved for high-wind zones unless reinforced.
For coastal or HVHZ (High Velocity Hurricane Zone) areas, an acrylic dome usually doesn’t meet local codes unless specifically rated for impact (which is rare). Impact glass, on the other hand, can handle the flying debris scenario that Florida’s storms produce. Even inland, if you desire longevity and a clear, durable lens, investing in laminated or tempered glass pays off—less chance of leaks, better thermal performance, and greater peace of mind come hurricane season.
3. Skylight Styles: Curb-Mount, Deck-Mount, & Tubular Options
Choosing the right style affects both aesthetics and leak protection in Florida:
- Curb-Mount Skylights:
- Raised Curb Advantage: A “curb” (wooden frame) raises the skylight above the roof plane, helpful for shedding water in Florida’s downpours.
- Installation Ease: If your old skylight was curb-mounted, you might reuse or reinforce that curb. Just ensure the flashing kit is updated to Florida code.
- Deck-Mount Skylights:
- Low Profile: Sits closer to the roof deck for a sleeker look. Might incorporate integrated flashing.
- Potential Leak Risk: If incorrectly installed, deck-mount edges could allow water intrusion, especially under Florida’s sideways rain. Reputable brands like Velux or Fakro design robust flashing kits for deck mounts though.
- Tubular/ “Sun Tunnels”:
- Compact Light Delivery: Perfect for hallways or bathrooms. A small dome on the roof channels sunlight through a reflective tube.
- Minimal Heat Gain, Lower Leak Chance: Less surface area means fewer infiltration points. Often cheaper than large skylight replacements.
In Florida, curb-mount designs remain popular for better water diversion, but deck-mount can excel if installed with high-grade flashing specifically tested for local wind-lift. Meanwhile, tubular skylights deliver surprising brightness without big structural changes—ideal if you simply want natural daylight in smaller spaces.
4. Sealing & Flashing Best Practices for Florida’s Storms
A new skylight might boast top-tier glass, but flashing and sealing ultimately protect it from leaks:
Manufacturer-Specific Flashing Kits:
Reputable brands supply custom flashing kits tested under Florida’s conditions. Using generic or mismatched kits can create gaps.
Peel-and-Stick Underlayment Integration:
Running a self-adhered membrane (like ice-and-water shield) around the skylight’s perimeter helps block wind-driven rain. Florida codes often require this if you’re re-roofing that section.
Proper Overlapping Shingles or Tiles:
The top portion of the skylight’s flashing usually tucks under the next course of shingles; side flashings overlap in a step pattern. For tile roofs, specialized “skylight tile pans” might be needed.
UV-Resistant Sealants:
Any external caulking or adhesive must handle Florida’s punishing sun. Basic silicone can degrade quickly, so roofing-grade polyurethane or tri-polymer sealants often fare better.
Check for HVHZ Approvals:
If you’re in Miami-Dade or Broward, ensure the skylight and its flashing system have the right Product Approval or Notice of Acceptance.
A slipshod flashing job, even with a premium skylight, typically leads to interior water damage in Florida’s next big storm. Insist on a licensed contractor (or if you’re DIY-savvy, follow the brand’s Florida-specific instructions meticulously). The synergy of robust materials, correct overlap, and thorough sealing makes all the difference here.
5. Specialty Features: Venting, Solar Power & More
Modern skylight replacements* often come with bells and whistles that suit Florida living:
- Ventilating Skylights: Some open to release hot attic air—useful if you want a natural breeze. Just confirm they’re rated for Florida’s wind-lift demands, and consider impact glass if near the coast.
- Solar-Powered Skylights: A small solar panel can power an electric motor to open/close the skylight or operate a built-in blind. Eco-friendly and no wiring needed.
- Rain Sensors:sealing
- UV Filtering & Low-E Coatings: Florida sun can bleach furniture or floors, so advanced coatings reduce harmful rays while letting natural light pass. This also helps manage heat gain.
Before splurging on high-tech options, weigh the extra costs. Florida’s storms might test motorized venting units more severely. Usually, big brands like Velux have rigorous testing for windy or coastal areas, making them safer bets than lesser-known vented models. If you’re far inland or have significant shading from trees, you might skip advanced solar features. Evaluate your home’s orientation, your budget, and how frequently you’d use venting or automatic blinds in Florida’s climate.
6. Professional Installation & Warranty Considerations
Swapping a skylight in Florida is no simple task. Professional installers ensure:
- Roof Deck Integrity: If you have older decking or hidden rot around the old skylight curb, they’ll replace it for a stable foundation. Florida’s humidity fosters rot quickly once moisture seeps in.
- Exact Flashing Fit: Skylight kits often come with step-by-step instructions. A pro ensures correct overlap with your roofing material, crucial in sideways storms or strong gusts.
- Code Approvals & Permits: Larger replacements or structural changes typically require county permits. Licensed Florida contractors handle these swiftly. Avoid unpermitted work—insurers might deny claims if a storm breaks an illegally installed skylight.
- Warranty Validation: Many impact skylight warranties require certified installation. If you DIY and something fails, you might lose coverage. A pro can also file the warranty properly.
Though you can attempt a small dome swap alone, Florida’s building codes and storm-laden conditions make professional help a safer bet—especially if you’re investing in an expensive impact-rated unit. Over your skylight’s life, that proper installation might save you from repeated leak repairs or water-damaged ceilings.
