Skylights can transform a dark room into one of the best spaces in your home. They bring in natural light from above – the most flattering and functional light source available – and in a place like Baton Rouge, they can help ventilate and brighten rooms that would otherwise rely entirely on artificial lighting.

But Louisiana is tough on skylights. The combination of intense UV exposure, summer heat, heavy rainfall, and occasional hurricane-force winds puts more stress on skylight glass and seals than most other climates in the country. Many homeowners don’t realize their skylight has a problem until they spot a stain on the ceiling or notice the room is getting noticeably hotter in summer.

If you have a skylight – or you’ve been thinking about adding one – here’s what you need to know.

Signs Your Skylight Glass Needs Attention

Water stains or active leaking. The most obvious sign. A small leak can quickly cause significant damage to insulation, drywall, and ceiling finishes. In Baton Rouge, summer thunderstorms will expose even a minor seal failure immediately.

Condensation between the panes. If you have a double-pane skylight and see fogging or moisture between the glass layers, the seal has failed. This is not a cleaning problem – the insulating gas has escaped and the glass unit needs to be replaced. It’s the same issue as fogged windows, just overhead.

Yellowing or discoloration. Older acrylic (plastic) skylights yellow significantly over time from UV exposure. If your skylight looks brown or amber, it’s blocking light and needs to be replaced. Glass skylights don’t have this problem.

Visible cracking or crazing. Acrylic bubbles, cracks, and crazes over time – especially in Louisiana heat. Glass holds up far better under prolonged UV and thermal cycling.

Noticeably hotter rooms. If the room under your skylight is significantly hotter than the rest of the house in summer, the glass is likely not energy efficient. Older single-pane or clear glass skylights act like a solar collector. Upgrading to a modern low-E glass unit can meaningfully reduce that heat gain.

Repair vs. Replace: How to Decide

Repair may work if: the leak is coming from the flashing or seal around the frame rather than the glass itself, the frame is in good structural condition, and the glass is still intact and performing reasonably well.

Replacement is usually the right call if: the glass is cracked, crazed, or yellowed; there is condensation between the panes; the skylight is more than 15 to 20 years old; the existing glass is single-pane or acrylic; or you’re seeing repeated leaks despite repairs.

In Baton Rouge’s climate, a skylight older than 20 years has typically reached the end of its functional lifespan for both the glass and the weatherproofing. A replacement is usually more cost-effective than ongoing repairs.

What Type of Glass Should You Choose?

Tempered Glass

The minimum standard for residential skylights in most building codes. Heat-treated to be significantly stronger than standard glass and designed to break into small rounded pieces rather than sharp shards. Most modern skylights use tempered glass as a base.

Laminated Glass

Laminated glass bonds two panes with a clear interlayer – similar to car windshields. If it breaks, the pieces stay bonded to the interlayer rather than falling into the room below. For overhead glass applications, laminated is often the preferred safety choice and may be required by code in some parishes.

Low-E Glass

Low-emissivity glass has a microscopic coating that reflects infrared heat while allowing visible light through. In Baton Rouge’s climate, a skylight with low-E glass can significantly reduce summer heat gain – making the room more comfortable and reducing your air conditioning load.

Double-Pane Insulating Units

Two panes of glass sealed with an insulating gas fill (typically argon) between them. Double-pane skylights dramatically outperform single-pane units for both energy efficiency and condensation resistance. If your current skylight is single-pane, upgrading to a double-pane unit with low-E coating is one of the highest-impact glass improvements you can make.

Local Providers and What to Know Before You Call

Several companies serve the Baton Rouge area for skylight work. Skylight installation is a combination of roofing work (flashing, waterproofing, framing) and glass work – whoever you hire should be experienced in both.

Bright Skylighting is a factory-authorized installer for major skylight brands including VELUX, Andersen, and Fakro and specifically serves the Baton Rouge market. Olympian Roof and HUDCO Roofing also service skylights locally.

For the glass component specifically – if your frame is in good shape and only the glass unit needs to be replaced – a local glass shop may be able to handle the glass panel replacement directly without a full roofer engagement.

Summer Is the Right Time to Address It

If your skylight has been on your list, July and August are ideal months to deal with it. You can see the heat gain issue firsthand, storm season is active so any seal vulnerabilities will show themselves, and getting work done now means you’re protected before fall cold fronts bring another round of rain.

At Big River Glass, we work with homeowners on glass replacement for skylights and can help you identify whether your situation calls for a glass-only repair or a full unit replacement.
