Are you interested in adding a Velux skylight to your home but feel unsure about the options available? Do the many different types, features, and prices of skylights seem overwhelming to navigate?
At RoofSmart, we’ve installed thousands of skylights, and often use Velux products for their durability and design. While this guide focuses on Velux skylights, it isn’t limited to Velux buyers—it’s designed to help anyone looking to install a quality skylight, no matter the brand.
In this article, we’ll break down the main types of Velux skylights, their costs, and the features that could make them a good fit for your home. By the end, you’ll feel confident about the features you need and have a clear idea of what to expect in terms of budget and installation.
What kinds of skylights does Velux offer?
Velux offers a wide variety of skylight options. This article will go over the most common types that they offer, breaking it down into 3 categories:
- Fixed skylights (deck-mounted and curb-mounted)
- Venting skylights (manual, solar-powered, or electric)
- Sun Tunnels
Each of these skylight types has its own unique features with different pros and cons and widely varying costs.
Fixed Skylights
Fixed skylights are referred to as “fixed” because they do not open (as opposed to venting skylights, which will be explored later on). This is the standard option for skylights and what most people end up choosing. They are also much more affordable than vented skylights.
If you want a skylight simply to let light into your home and brighten up your space, then a fixed skylight is a great option.
Velux offers two main types of fixed skylights: deck-mounted and curb-mounted. Each one comes in a wide variety of sizes, which impacts the cost. As you go up in size, the cost will increase.
Deck-Mounted Skylight Options
Deck-mounted skylights are installed right into the roof deck and sit flush with the top of it. This type of skylight is a good choice for you if you want to install the skylight yourself because it requires less specialized roofing skills than needed to install a curb-mounted skylight.
To make this process more convenient (whether or not you hire someone to install the skylight for you), Veulx offers flashing kits that are customizable to fit with the skylight you chose. They range between $108.00 and $298.00. This cost is additional to the cost of your skylights.
Velux offers 14 sizes of deck-mounted skylights, ranging in cost from $309 to $604. For example, this is the Velux FS C12:
It is 21 inches by 70 inches and costs $548.
Other sizes and prices include:
| Size (in inches) | 14 X 46 | 21 X 27 | 21 X 38 | 21 X 46 | 21 X 54 | 23 X 46 | 23 X 23 | 30 X 30 | 30 X 38 | 30 X 46 | 30 X 54 | 44 X 27 | 44 X 46 |
| Cost | $348 | $309 | $356 | $397 | $428 | $409 | $335 | $386 | $419 | $474 | $518 | $478 | $604 |
Curb-Mounted Skylight Options
Curb-mounted skylights sit a few inches above the roof deck on top of a frame. The height varies based on your roof’s circumstances. Your installer can recommend a height that will work best for your roof.
Curb-mounted skylights are desirable to some homeowners because they make replacing the skylight incredibly easy. Since the skylight is in an elevated position, you do not need to tear up and then repair the roof as part of the replacement process (this is necessary with deck-mounted skylights).
Velux does offer flashing kits to go with curb-mounted skylights, but if you have a professional install the skylight then it’s a good idea to discuss with them alternate options for getting flashing. They might not need a kit.
Velux offers 17 different options for standard-sized curb-mounted skylights ranging in cost from $230 to $802. For example, this is the Velux FCM 1430:
This skylight is 14 inches by 30 inches and costs $285.
Other sizes and prices include:
| Size (in inches) | 14 X 30 | 14 X 46 | 22 X 22 | 22 X 30 | 22 X 34 | 22 X 46 | 22 X 70 | 30 X 30 | 30 X 46 | 30 X 55 | 34 X 34 | 34 X 46 |
| Cost | $285 | $313 | $230 | $268 | $285 | $302 | $505 | $324 | $432 | $478 | $402 | $453 |
| Size (in inches) | 46 X 22 | 46 X 30 | 46 X 34 | 46 X 46 | 46 X 72 |
| Cost | $302 | $432 | $453 | $473 | $802 |
The curb-mounted skylights also come in 19 custom sizes, which are more expensive than the standard sizes. Each skylight option has multiple widths and heights you can choose from to fit your needs. They range in price from $434 to $1,060.
Venting Skylights
Venting skylights give you the option of opening your skylight. They open out like an awning. This type of skylight is also split into deck-mounted and curb-mounted options, but the other important categories to consider here are manual, solar-powered, and electric.
Venting skylights can be beneficial if you are in a home that needs additional ventilation up high. Manual venting skylights are the cheapest option, but solar-powered and electric venting skylights are more convenient because they close at the press of a button.
Manual Venting Skylights
The manual option is operated by a telescopic rod that allows you to reach up to the skylight and hand-crank it open or closed. The deck-mounted options cost between $600 and $962. The curb-mounted options cost between $579 and $1,138.
The Velux VCM 2246 (a curb-mounted manual skylight) looks like this:
It is 22 inches by 46 inches and costs $727.
Other sizes and prices for deck-mounted manual venting skylights include:
| Size (in inches) | 21 X 27 | 21 X 38 | 21 X 46 | 21 X 54 | 30 X 30 | 30 X 38 | 30 X 46 | 30 X 54 | 44 X 27 | 44 X 46 |
| Cost | $600 | $648 | $686 | $719 | $677 | $710 | $710 | $845 | $767 | $962 |
Other sizes and prices for curb-mounted manual venting skylights include:
| Size (in inches) | 22 X 22 | 22 X 34 | 22 X 46 | 30 X 30 | 30 X 46 | 34 X 34 | 46 X 46 |
| Cost | $579 | $670 | $727 | $780 | $990 | $891 | $1, 138 |
Solar-Powered Venting Skylights
If you do not want to manually open your skylights and you want an eco-friendly option, solar-powered venting skylights are a good option for you. Not only are they convenient, but they’re also eligible for the federal tax credit.
The size options for solar-powered venting skylights range in cost from $1,279 to $1,834.

| Cost | $1,279 | $1,360 | $1,426 | $1,479 | $1,394 | $1,465 | $1,559 | $1,661 | $1,569 | $1,834 |
Electric Venting Skylights
Another option if you want to avoid having to manually open and close your skylight is to get an electric one. That way, you can control it with a remote and don’t have to worry about disrupting what you’re doing to close the skylight in the rain.
The size options for deck-mounted electric venting skylights range in cost from $1,279 to $1,834. The size options for curb-mounted electric venting skylights range in cost from $1,310 to $1,731.

Sun Tunnel
The Sun Tunnel is the Velux version of a tubular skylight. These types of skylights are round and have a long cylinder underneath that can reach down very far. These are great for installing in the ceiling of your attic so that you can still funnel in light from the outside.
These are typically cheaper and easier to install than standard deck-mounted or curb-mounted skylights, so if all you want is some light then something like the Sun Tunnel might be a good option for you.
This is what they look like:
Depending on the size, model, and glass type you choose, the Sun Tunnel will cost you between $224 and $816.
