Skylights for Your Florida Home: Benefits, Drawbacks, and Leak Prevention
Thinking about skylights for your Florida home? Here are the real benefits, the heat and leak risks in our climate, and how to keep a skylight watertight.
There is something about a room full of daylight that a regular window just cannot match. Skylights pull sunshine straight down from above, open up a space, and can lift the whole mood of a home. In Florida, where the sun shows up nearly every day, a skylight is tempting. They also come with a couple of real catches in our climate, mostly around heat and leaks. Here is an honest look at what skylights can do for your home, what to watch out for, and how to keep one from becoming a headache.
The bright side of skylights
The obvious draw is natural light. A well placed skylight can flood a dim kitchen, bathroom, or hallway with sunshine and make a small room feel far bigger. That daylight is easy on the eyes and on the electric bill, since rooms that light themselves during the day need fewer lamps switched on. Many homeowners also just feel better in a sunlit space, and a venting skylight that opens can let hot air escape and bring a little fresh air through on a mild day.
The Florida catch: heat and leaks
The same sun that makes skylights lovely also makes them a source of heat. A clear, untreated skylight can pour warmth into a room and give your air conditioner more to do, which is the last thing you want in a Florida August. Choosing the right glass, which we get to below, makes a big difference here, and the attic heat and ventilation that affects the rest of your roof is worth thinking about with skylights too. The bigger worry, though, is leaks. A skylight is a hole cut in your roof, and every seam around it has to shed water perfectly through heavy summer storms and hurricane season. Done right, it stays dry for years. Done poorly, it becomes the first place your roof lets water in.
Common types of skylights
Not all skylights are the same, and the type you pick shapes both the light and the risk:
- Fixed skylights do not open. They are the simplest and, with fewer moving parts, often the least likely to leak.
- Ventilating skylights open to let hot air and moisture out, which is handy over a kitchen or bathroom.
- Tubular skylights, sometimes called sun tunnels, are small reflective tubes that funnel daylight into a closet, hallway, or other tight spot where a full skylight will not fit.
Glazing matters as much as the type. In Florida, look for low-E, insulated glass, and impact-rated units that can stand up to our sun and our wind.
Keeping a skylight watertight
With skylights, the flashing is everything. Flashing is the layered metal and sealing that ties the skylight into the surrounding roof, and it is what actually keeps water out. This is not a job for a handyman with a tube of caulk. Caulk alone will fail, and a skylight set without proper flashing is a roof leak waiting to happen. A roofer who installs it correctly, with the flashing woven into the shingles and the curb sealed the right way, is what makes the difference between a skylight that lasts and one that drips.
The best time to add or replace one
If a new skylight is on your wish list, the ideal moment is during a roof replacement. With the roof already open, a roofer can set the skylight and integrate the flashing into the fresh shingles from the start, which is cleaner and more watertight than cutting into an existing roof later. The same goes for an old skylight. If yours is near the end of its life and the roof is being redone, replace them together so the two ages match and you are not opening a new roof a few years down the road.
Signs your skylight needs attention
An aging or poorly installed skylight usually tells on itself. Watch for:
- Water stains or drips on the ceiling or wall around the frame
- Fog or condensation trapped between the panes of glass
- Cracks in the glass or dome, or a frame that looks warped
- A noticeable draft, or a room that runs hotter than the rest of the house
Bringing in the light, the right way
Skylights can be a wonderful upgrade when they are chosen and installed with Florida in mind. Pick an energy-efficient, impact-rated unit, look for the ENERGY STAR label for your climate zone, and have it put in by a roofer who will flash it properly.
