Skylights in Northeast Florida: Hurricane-Rated Options and When They Actually Make Sense

Skylights are one of those upgrades homeowners in Jacksonville, FL ask us about every spring — usually right after a kitchen remodel or a great-room addition. The honest answer is that a skylight is either one of the best dollar-for-dollar improvements you can make, or one of the most reliable sources of leak calls for the next twenty years. Which one depends almost entirely on the unit you pick, where it sits on the roof, and who flashes it in. Here is how Joey Lappin, owner of Lappin Roofing, talks Northeast Florida homeowners through the decision.

Why skylights are a different conversation in Florida

A skylight in Ohio is mostly a thermal-loss problem. A skylight in Northeast Florida is a wind, water, and UV problem — in that order. Our service area covers Duval, St. Johns, Nassau, Clay, and Flagler counties, and every one of those is in a Florida Building Code wind zone that demands a skylight rated for the missile and pressure tests for the address. The cheap big-box dome you saw in your uncle's house in 1998 will not pass the inspection on a 2026 Jacksonville permit, and it should not.

The good news: hurricane-rated skylight technology has come a long way. The right unit, properly curbed and flashed, will outperform the surrounding shingle field for water-tightness and carry a manufacturer warranty that beats most roof systems.

Hurricane-rated options that actually make sense

Deck-mounted, impact-rated fixed skylights

The current standard for Northeast Florida is a deck-mounted, impact-rated fixed skylight with laminated outer glass and tempered inner glass. These units sit low to the roof plane, integrate with a step-flashed shingle field, and carry wind ratings that match or exceed the roof system. For a great room, hallway, or stairwell where you just want light, this is the right call.

Curb-mounted units on flat or low-slope sections

If the skylight is going on a flat addition, porch, or low-slope hallway, a curb-mounted unit on a properly built site-fabricated curb is the better answer. The curb lifts the unit above the water plane and lets us run a TPO or modified bitumen field underneath without compromise. We see fewer leak calls on curbed units than on any other style.

Venting (operable) skylights

Operable skylights add real value in a kitchen or bathroom for natural ventilation. They cost more, have more moving parts, and need their seals serviced every 5–7 years in Florida humidity, but a well-installed venting unit will last 20+ years and meaningfully reduce summer cooling load.

Solar tubes (tubular daylighting devices)

For closets, interior bathrooms, hallways, and laundry rooms, a 10- or 14-inch solar tube is almost always the smarter purchase than a true skylight. They cost a fraction of an impact-rated unit, leak almost never (small flashing footprint), and deliver surprising amounts of natural light. We install far more solar tubes in Northeast Florida than fixed skylights, and our callback rate on them is essentially zero.

Where a skylight makes sense — and where it does not

Before you commit, walk through these considerations honestly:

• Room use: Skylights pay you back in rooms you spend daytime hours in (kitchens, great rooms, home offices). They are wasted on bedrooms you only use at night.
• Roof slope: Steeper slopes drain better and hide skylights gracefully. Slopes under 4/12 demand curb-mounted units and careful detailing.
• Roof orientation: South- and west-facing skylights in Jacksonville bring meaningful summer heat gain. North-facing units deliver soft, even daylight without the heat penalty.
• Tree cover: Heavy oak canopy means leaf debris and branch impact risk. Plan a maintenance routine, or pick a different room.
• Roof age: A new skylight on a 17-year-old roof is a flashing detail that will outlast the surrounding shingle. Better to install during a full replacement so the curb, flashing, and field are all the same age.
• Insurance posture: Some Florida carriers have raised questions about skylight count and rating. Confirm with your agent before adding new units.

Installation details that decide whether a skylight leaks

The skylight itself is rarely the problem. The flashing field around it is. A correctly installed deck-mounted skylight in Northeast Florida includes:

• An ice-and-water shield wrap over the entire curb and out a minimum of 18 inches in every direction
• A step-flashing kit matched to the unit and shingle profile
• A head-flashing diverter that pushes water around the upper edge before it has a chance to find a fastener
• A back-pan and counter-flashing assembly that integrates with the field, not a bead of caulk
• Written confirmation that the unit's wind rating meets or exceeds your address's design pressure

If a roofer cannot describe these details on the phone, do not let them install your skylight. We have replaced enough botched installs to know that one missing component upstream means a leak downstream within five years.

What we install and warrant

Lappin Roofing sources skylights through ABC Supply and SRS — the same suppliers we use for Owens Corning shingle, underlayment, and flashing. That gives us access to current Florida-rated units with full manufacturer documentation and parts availability for service work down the line. Every skylight install we do is covered under the same 10-year workmanship warranty we put on every roof, on top of the manufacturer's product warranty. If we install a skylight and it leaks because of how we flashed it, we come back and make it right.
