TL;DR: Summary
A venting skylight opens to let fresh air out as well as daylight in. (Manufacturer image)
Velux offers three main skylight categories: Fixed, Venting and Sun Tunnels.
- Fixed skylights are the most affordable and popular way to add light.
- Venting skylights (manual, electric or solar-powered) add airflow.
- RoofSmart installed price: $816 plus tax for the tunnel, plus $224 plus tax for the flashing.
For Seattle homes, the big choice is deck-mounted (flush with the roof) or curb-mounted (raised on a frame).
Curb-mounted skylights are generally more leak-resistant and easier to replace.

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
For example, this is the Velux FS C12:
It is 21 inches by 70 inches and costs $1,004.97 plus tax.
Price at Home Depot, checked Oct 15, 2026.
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 if you want to install the skylight yourself.
It requires less specialized roofing skill than a curb-mounted skylight.
Velux offers flashing kits that are customizable to fit the skylight you chose.
They make the process more convenient, whether or not you hire someone to install the skylight for you.
Flashing is an added cost on top of the skylight price.
Velux makes 14 sizes of deck-mounted fixed skylights.
At Home Depot they run $580.01 to $1,107.14 plus tax (with solar room-darkening shade).

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 sits in an elevated position, you do not need to tear up and then repair the roof to replace it.
With deck-mounted skylights, that step is necessary.
Velux does offer flashing kits for curb-mounted skylights.
If a professional installs your skylight, it’s a good idea to ask them about alternate options for flashing.
They might not need a kit.
Velux makes 20 standard curb-mounted fixed sizes.
The 13 sold at major retailers run $343.68 to $1,201.62 plus tax, unit only; 7 are Not listed at retail.

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. The other important categories to consider here are:
- Manual
- Solar-powered
- 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 Velux VCM 2246 (a curb-mounted manual skylight) looks like this:
It is 22 inches by 46 inches and costs $989.00 plus tax.
Price at Home Depot, checked Oct 16, 2026 (Lander #4702, Seattle).
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 $1,027.39 and $1,580.76 plus tax.
Price at Home Depot, checked Oct 15, 2026.
The curb-mounted options cost between $915.56 and $1,711.30 plus tax.

Electric Venting Skylights

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.
If all you want is some light, something like the Sun Tunnel might be a good option for you.
This is what they look like:
RoofSmart installed price: $816 plus tax for the tunnel, plus $224 plus tax for the flashing.
Retail prices for Velux Sun Tunnel kits are listed below. Retail TGR and TMR kits bundle the flashing in the kit price.

Frequently Asked Questions
1. What is the difference between deck-mounted and curb-mounted skylights?
Deck-mounted skylights are installed directly into the roof deck for a low-profile look. Curb-mounted skylights sit on a raised wooden frame (a curb). Curb-mounted versions are often preferred in rainy climates because they elevate the glass above the water-shedding level of the roof.
2. Do venting skylights close automatically when it rains?
Yes, but only the electric and solar-powered models. These units are equipped with rain sensors that trigger the skylight to close at the first sign of moisture. Manual venting skylights must be closed by hand using a telescopic rod.
3. Are solar-powered skylights worth the extra cost?
In many cases, yes. While they have a higher upfront cost, they require no complex electrical wiring, making installation simpler than electric models. Solar models qualified for the federal tax credit, which ended for systems installed after December 31, 2025.
4. What is a Sun Tunnel?
A Sun Tunnel is a tubular skylight designed for spaces where a traditional skylight won't fit, such as hallways or bathrooms under an attic. It uses a highly reflective pipe to funnel light from the roof down to the ceiling below.
5. Can I install a Velux skylight myself?
While Velux offers flashing kits to simplify the process, skylight installation involves cutting into your roof’s structural system and ensuring a waterproof seal. Professional installation is highly recommended to maintain the manufacturer’s warranty.
6. How much does a basic fixed skylight cost?
At Home Depot (checked Oct 15 and 16, 2026), standard fixed Velux skylights run $343.68 to $1,107.14 plus tax, unit only (curb-mounted $343.68 to $855.67; deck-mounted $580.01 to $1,107.14). The large FCM 3171 is $1,201.62 plus tax at Ferguson Home (checked Oct 15, 2026).
7. Why is a deck-mounted skylight more likely to leak than a curb-mounted one?
Because deck-mounted units sit flush with the roof, they rely heavily on the seal between the unit and the roof deck. You can learn more about why deck-mounted skylights are more prone to leaks compared to the elevated curb-mounted style.
8. How much does professional skylight installation cost in Seattle?
Labor costs vary based on the pitch of your roof and the type of skylight chosen. To get a better idea of your total budget, check out our guide on how much it costs to install a skylight in the Seattle area.
9. What are the common problems with OSB roof decking when installing skylights?
If your roof uses OSB decking, adding a skylight requires extra care. OSB is highly susceptible to moisture, so you should be aware of the common problems with OSB roof decking to ensure your new skylight doesn't lead to structural rot.
10. Could my skylight leak be caused by a gutter issue instead?
Sometimes water intrusion near the eaves is mistaken for a skylight or roof leak. It is important to diagnose the source correctly by determining if your roof leak is caused by the roof or gutter guards before scheduling a skylight repair.
