Replacement skylights are a practical upgrade for any home where the existing unit is leaking, discolored, cracked, or simply too old to perform well.
Quick answer — you likely need a replacement skylight if you notice:
You have two main paths forward:
Option Best For Typical Cost Dome-only replacement Intact frame, cracked or yellowed dome $45 – $600 Full unit replacement Leaking frame, outdated insulation, age $2,000 – $5,250
Both options are covered in detail below, so you can make the right call for your home and budget.
A skylight that once filled your living room with warm, natural light can quietly become a source of heat loss, water damage, and frustration. The problem is that most homeowners don't notice the warning signs until real damage has already set in — a water stain spreading across the ceiling, a dome that has gone from clear to a murky yellow, or an energy bill that keeps climbing for no obvious reason.
The good news is that modern replacement options are better than ever. Today's skylights offer superior insulation, impact-resistant materials, and smart features like solar-powered shades — all in a package that can often be installed in as little as four hours.
I'm Matt Lopez, founder of Matt's Exteriors, and over nearly two decades of exterior remodeling across Metro Atlanta I've guided hundreds of homeowners through the process of selecting and installing replacement skylights that perform for the long haul. This guide covers everything you need to make a confident, informed decision.
In our experience serving Metro Atlanta since 2007, we’ve seen that skylights rarely "just break" overnight. They tend to give you subtle hints before they fail completely. If you’ve been looking up and wondering if that slight haze is just dirt or something more serious, it’s time to pay attention.
The most obvious sign is physical damage. If you see cracks in an acrylic dome or spiderwebbing in glass, the structural integrity of the unit is compromised. Beyond cracks, keep an eye out for:
If you are noticing these issues, our Skylight Repair Services can help diagnose whether a simple fix is possible or if it's time for a full swap. We also provide expert professional skylight replacement in Loganville & Snellville, GA, for units that are beyond repair.
We often get asked: "Can't I just pop a new plastic lid on there?" The answer depends on the health of the frame.
If your skylight frame is made of wood and shows signs of rot, or if the metal frame is warped and leaking, replacing just the dome is like putting a new roof on a house with a crumbling foundation. You should opt for a full unit replacement if:
By choosing a full unit replacement, you ensure that the flashing, frame, and glass all work together as a single, warrantied system.
When selecting replacement skylights, the material you choose impacts everything from how much noise you hear during a Georgia thunderstorm to how well your AC keeps up in July.
Accuracy is everything. If you order a dome that is even half an inch off, it won't sit properly on the curb, leading to immediate leaks. To get it right, you need three sets of numbers:
For those considering a DIY approach or looking to understand the technical side, our guide on Curb Mount Skylight Installation provides deeper insights into these requirements.
The "color" of your skylight determines the quality of light and the amount of heat entering your home. In the Atlanta sun, this is a critical choice.

If your current skylight was installed in the 1990s or early 2000s, you’ll be amazed at how much technology has changed. Modern replacement skylights aren't just windows in your roof; they are advanced home appliances.
Modern units use Low-E (low-emissivity) glass coated with microscopic layers of silver to reflect heat and provide UV protection while letting light through. Many are also filled with Argon gas between the panes to provide a thermal barrier.
One of the biggest game-changers is the "Fresh Air" skylight. These can be solar-powered, meaning they require no wiring. They open to let out hot air (which naturally rises to the ceiling), creating a "chimney effect" that cools your home naturally. Even better, they often come with rain sensors that automatically close the unit at the first sign of a drizzle. Many of these solar-powered models even qualify for federal tax credits, significantly offsetting the installation cost.

Not every skylight replacement happens on a traditional roof. We often see a need for smaller, more specialized units.
For homeowners in the city, Professional Skylight Installation in Atlanta often involves navigating these compact or specialized solutions to maximize light in tight urban floorplans.
Is replacing a skylight a DIY project? If you are just swapping a dome on an existing, healthy curb, a handy homeowner can often do it in about an hour. However, if you are replacing the full unit or dealing with the flashing, we strongly recommend professional help.
If you’ve determined that your frame is in great shape and you only need a new dome, here is the general process:

One of the best times to consider replacement skylights is during a roof replacement. Why? Because the labor is already there. Replacing a skylight during reroofing can take as little as 30 minutes for a pro, whereas doing it as a standalone project requires much more setup.
Furthermore, when we install a new skylight along with a new roof, we can synchronize the warranties. This means you don't have to worry about a roofing manufacturer blaming a skylight installer (or vice versa) if a leak develops. As Certified VELUX Skylight Installers, we can offer "No Leak" warranties that cover both the product and the installation for up to 10 years. These modern upgrades can result in a 28-36% increase in energy efficiency for your home.
The cost varies wildly based on the scope. A simple replacement dome can cost between $45 and $600 for the part. However, a professional full-unit replacement typically ranges from $2,000 to $5,250. Factors that drive the price up include steep roof pitches, high ceilings (over 18 feet) that require scaffolding, and the need for new interior drywall work.
A simple dome retrofit can be done in 30 to 60 minutes. A standard full unit replacement on an existing opening usually takes about 4 hours. If we are cutting a brand-new hole in your roof and building a "light shaft" through an attic, expect the project to take 1 to 2 days.
When you choose high-quality brands like VELUX and have them installed by a certified pro, you typically get a 10-year warranty on the installation and a 20-year warranty on the glass seals. Some systems even offer a "No Leak Guarantee" when installed with the proper proprietary flashing kits.
Replacing your skylight is one of the most effective ways to brighten your home, improve energy efficiency, and protect your roof's integrity. Whether you need a simple dome swap or a modern, solar-powered "Fresh Air" system, the key is choosing the right materials and ensuring a watertight installation.
