A Guide to Skylights for Arizona Homes

Few upgrades transform a home quite like adding natural light. Skylights aren’t just beautiful; they serve a purpose, too: reducing energy use, improving indoor comfort, and even boosting individuals’ moods due to the light they provide. Those who are interested in adding a skylight might not want to DIY it before talking to a professional – that’s where Rosie on the House Certified Partners experts like Tyler Green of Freelite AZ come in. Here’s what homeowners should know before installing a new skylight.

The most energy-efficient skylights for Arizona

When the temperatures eventually soar into triple digits, efficiency matters. According to Green, “VELUX glass skylight units are the most energy-efficient skylights as they come with dual-glazed, low-e, argon gas-filled glass and interior blinds.”

The combination is powerful: dual glazing reduces heat transfer, low-e coatings block UV damage and excess heat, and argon gas is a natural insulator. And, because our Phoenix sun isn’t exactly subtle, interior blinds can help you control brightness and temperature on demand.

Warranties: what to look for and why they matter

Roof penetrations aren’t something you want to gamble with. That’s why warranty details matter as much as the product itself. Warranties in this industry can vary depending on the product and manufacturer, so it’s always a good idea to consult with a sales professional when exploring your options. Make sure to talk through warranty terms before selecting the brand, because the professionals may spot limitations most homeowners overlook.

What’s important to note is that installation is the longest-warrantied component (10 years). This protects against everyday wear and tear while the overall product comes with its own guarantee. Upgraded accessories like blinds and venting capabilities also come with separate warranties.

Fixed, vented, or tubular? Finding the right skylight

You have options, and choosing the right one depends on how the space is used. There are several types of skylights, but Green said the most popular or well-known are fixed, venting, and tubular.

Fixed skylights remain sealed, delivering daylight without airflow – these are perfect for living rooms, stairwells, or vaulted ceilings. Vented skylights open to bring in fresh air, functioning like roof-mounted windows. Green said these are for kitchens, bathrooms, or anywhere airflow matters.

Tubular skylights act like light tunnels for compact spaces. They collect sunlight through a rooftop dome and deliver it down a reflective tube, brightening hallways, closets, and laundry rooms without overpowering the area.

The 3 basic types of skylights are vented, tubular and fixed.

How skylights impact temperature and efficiency

Skylights aren’t just pretty; they can help balance indoor comfort. A well-designed model decreases daytime reliance on electric lights, and vented units allow natural air exchange in stuffy areas. Modern skylights use advanced glazing to limit heat gain in the summer and heat loss in the winter.

Poor-quality skylights, on the other hand, can have the opposite effect: extra warmth in July and chilly drafts in January. This is why Phoenix homeowners gravitate toward high-performance glass options over older acrylic designs.

Glass vs. acrylic maintenance

Speaking of acrylic – not all skylights age the same.

“Generally, for VELUX glass skylights, there is no routine maintenance needed, other than cleaning the glass like you would a window,” Green said. Acrylic skylights, however, require closer oversight. They can fade, crack, or develop worn-out seals. “It is a good idea to keep an eye on the condition of the acrylic models and weep holes, which are small openings designed to allow water to run off, should there be water intrusion through the outer dome.”

There is one thing Green is adamant about: glass skylights are a far better option for longevity and performance over time.

The pros and cons

There’s a reason skylight often become a homeowner’s favorite upgrade. The biggest pro of installing a skylight in an existing structure is the natural light it provides. The additional sunlight elevates mood and interior aesthetics, and in many spaces, skylights can introduce airflow where windows can’t be installed.

Vented skylights let hot indoor air escape naturally, much like a chimney effect. They reduce humidity, release cooking fumes, and help refresh stuffy rooms. According to Green, they “allow for fresh air to enter the home just like any operational window.”

But – as with any upgrade – there can be drawbacks.

“The cons would be the potential of heat loss in the winter and heat gain in the summer, depending on the type of skylight,” Green explained. Installation costs have also increased in recent years, and structural retrofits – especially in older roofs – can add to the price tag.

Skylight technology is smarter than ever.

If you’re imagining a skylight that opens with the press of a button, you’re not dreaming.

Freelite installs several solar-powered skylights, and Green said they’re one of the most reliable options. The battery may eventually need to be replaced, but the solar panel and motor “seem to hold up indefinitely,” he said.

Skylights used to be simple windows in the ceiling. Today, they’re closer to smart home devices.

“All of the VELUX skylights now come equipped with internal blinds to allow for increased efficiency and the ability to completely cut off light, as well as smart rain sensors should you forget to close the skylight – but those are for venting units only,” Green said.

And his personal favorite innovation?

“The ability to control either a single or multiple skylights via the VELUX Active application on your phone is available for both venting and blinds.”

Imagine waking up, tapping an app, and watching your skylights open as the morning sunlight pours in. That’s not the future – that’s now! Skylights are more than architectural jewelry. Done well, they transform the feel of a home, improve air flow, reduce utility bills, and create a connection to the outdoors that ceiling lights can’t match.
