A skylight can flood a room with free daylight and make a dark hallway or bathroom feel twice as big. But in Florida, it’s also one of the most common places a roof springs a leak. At Affordable Roofing & Construction, a big share of the leak calls we run in Daytona Beach, Port Orange, and New Smyrna Beach trace back to an aging or poorly installed skylight. Here’s what every Volusia County homeowner should know before that daylight turns into a drip.
Why skylights leak in Florida
A skylight is a hole cut in your roof. Everything protecting your home from water depends on the flashing — the layered metal and sealant that ties the skylight into the surrounding shingles. Under Florida’s punishing UV load, afternoon downpours, and wind-driven rain, those materials break down faster than the roof around them.
The most common failure points we see:
- Worn flashing and sealant — the number-one culprit. Sealant that was fine at installation dries, cracks, and pulls away after years in the Florida sun.
- Failed seals on the glass or dome — older skylights fog up between the panes or crack, letting water sit and seep.
- Condensation mistaken for a leak — humid Florida air meeting cool glass can drip like a leak even when the roof is sound. Proper attic ventilation helps here.
- Old plastic domes — acrylic and polycarbonate bubbles yellow, get brittle, and crack after 10–15 years of sun exposure.
The one rule that saves homeowners the most money
If you’re getting a new roof, replace the skylights at the same time — even if they aren’t leaking yet. This is the single most important thing we tell homeowners about skylights.
Here’s why: the flashing that seals a skylight is woven into the shingles around it. When we tear off and reinstall the roof, that flashing has to come out and go back in either way. Reusing a 15-year-old skylight under a brand-new roof means you’ve bolted an old, sun-worn part into a system that should last decades — and when that old skylight fails in a few years, someone has to open up your new roof to fix it. Replacing it during the re-roof costs a fraction of doing it as a separate job later, and it keeps your roof warranty clean.
Signs your skylight needs attention
- Water stains, discoloration, or bubbling on the ceiling around the skylight
- Visible condensation or fogging between the panes of glass
- Cracks, yellowing, or a hazy look on an older plastic dome
- Drafts, or a room that’s noticeably hotter than the rest of the house
- Peeling paint or soft drywall in the light shaft below the skylight
Catching these early can mean a simple reflash or replacement instead of repairing rotted decking, insulation, and drywall down the line.
Types of skylights — what fits a Florida home
Fixed skylights are sealed and don’t open — the simplest, most leak-resistant, and least expensive option. Great for adding light to a living room or stairwell.
Vented (opening) skylights can be cranked or motored open to release hot, humid air — useful over kitchens and bathrooms, though there’s one more seal that can eventually fail.
Tubular skylights (sun tunnels) are compact reflective tubes that pipe daylight into small, dark spaces like closets, hallways, and laundry rooms. They’re affordable and rarely leak because the opening is small.
We generally recommend glass units over plastic domes for Florida homes. Modern low-E glass resists yellowing, blocks a good share of heat and UV, and holds up far better to our sun than acrylic bubbles.
Skylights, wind, and the Florida Building Code
Volusia County sits in a wind-borne debris region, and any skylight installed today has to meet Florida’s strict impact and wind-load requirements. When you re-roof, this is another reason to swap out an older skylight: today’s impact-rated units are built to take a beating from hurricane-driven debris that a 15-year-old dome simply wasn’t designed for. A properly rated, properly flashed skylight is part of a roof that stands up to storm season — not a weak spot in it.
What does a skylight cost?
Pricing depends on the type, size, and whether you’re replacing an existing unit or cutting in a new one. As a rough guide, a straightforward fixed or tubular skylight is the most budget-friendly, while vented and motorized units and any new framing cost more. The best value by far is bundling skylight replacement into a full re-roof, because the crew, the tear-off, and the flashing work are already happening. We’ll give you exact numbers in a free, no-pressure estimate — no guessing off a chart.
Thinking about adding a skylight?
A re-roof is the ideal time to add one. The roof is already open, the crew is already on site, and we can frame, flash, and seal the new opening as an integrated part of the roof system rather than a patch cut in later. If you’ve always wanted more natural light in a dim kitchen or bathroom, mention it when we come out — we’ll walk your attic and roofline and tell you honestly whether it makes sense for your home.
