Skylights are great for bringing in sunlight and fresh air, making rooms feel bigger and more comfortable. They are especially useful in cold places for getting sunlight in winter, and in hot places for letting in cool air.
The main difference between deck-mounted and curb-mounted skylights is how they look and where they sit. Deck-mounted skylights are fixed directly onto the roof, giving them a sleek, smooth look. Curb-mounted skylights, on the other hand, are installed on a raised frame (the curb) on the roof, which makes them stick out more.
Deck vs Curb Mounted Skylight: How To Choose?
When picking between curb-mounted and deck-mounted skylights, here’s what you need to know:
- Curb-mounted skylights are not as good at saving energy as deck-mounted ones, but they cost less to buy and are easier to fix.
- The type of roof you have is important. If you have a flat or gently sloping roof, like on many commercial buildings, you’ll need a curb-mounted skylight. This type sits on a raised frame.
- For steeper roofs, common in houses where the outside look is important, a deck-mounted skylight is better. These are installed directly onto the roof, giving a neater look.
- Not every building will fit these general rules, but the slope of your roof will usually guide you to the right choice.
- Skylights can really change a room, bringing in more natural light and air. But it’s important to understand these differences before choosing one.
What is Deck Mounted Skylight?
A deck-mounted skylight is a type of roof window known for its sleek look and is often considered more visually appealing.
These skylights come with pre-engineered frames and parts, such as curbs, matching covers, and flashing kits, which make installation easier. The built-in frame or curb of the skylight eliminates the need for separate construction and waterproofing.
To ensure a watertight installation, a flashing kit is used to cover the seam between the skylight and the roof. Deck-mounted skylights are what most people think of when imagining a skylight.
They’re great for maximizing ventilation and providing a clear view of the sky but do require significant work on the roof for proper installation.
They are particularly suitable for homes with steeper roofs where the external appearance is a priority. In contrast, buildings like commercial structures with flat or low-pitched roofs typically require a curb-mounted skylight.
What is Curb Mounted Skylights?
Curb-mounted skylights are typically chosen for flat or low-pitched roofs, particularly those with angles less than 14 degrees.
These skylights are installed on a raised frame, known as a curb, which is built along the edge of the roof, usually from wood, and then fastened securely to the roof.
The skylight itself consists of a frame holding glass panels, complete with rubber seals and sometimes a lighting system.
One of the advantages of curb-mounted skylights is that if the roof needs replacing, the skylight doesn’t need new flashing, which is the material that prevents water leakage.
This feature makes them a practical option for frequent replacements or as a substitute for an older skylight.
Additionally, curb-mounted skylights are often more affordable and come in standard sizes, contrasting with the more customizable but complex deck-mounted options.
Deck vs Curb-Mounted Skylight: Key Factors Comparison
Choosing between a deck-mounted and a curb-mounted skylight for your home can be tough. Here’s a simple breakdown of the differences:
Cost
Curb-mounted skylights are usually cheaper. They’re easier to install because once the curb (a raised frame) is built, putting the skylight on top is straightforward.
Deck-mounted skylights might need more work to fit them properly and require regular checks for leaks. Deck-mounted skylights can cost between $150 to $2500, while curb-mounted ones range from $150 to $1500.
Curb-mounted skylights don’t just save on initial costs; they also reduce labor expenses because they are easier and quicker to install.
Once you build the curb, the skylight fits right on top. In contrast, deck-mounted skylights, while offering a more integrated look, may require structural changes to your roof, adding to the cost.
The ongoing maintenance for deck-mounted skylights, especially for leak repairs, can add up over time.
Size
Curb-mounted skylights are often smaller, making them a good choice for tight spaces like bathrooms and closets.
Curb-mounted skylights are usually smaller, making them ideal for rooms where space is limited. They can be a great addition to small rooms, providing enough light without overwhelming the space.
Deck-mounted skylights, being larger, are suited for bigger rooms where more natural light is desired.
Their size allows for more sunlight and can make a significant difference in larger living spaces or main areas of a home.
Roof Pitch
This is about how steep your roof is. Deck-mounted skylights are better for steep roofs, while curb-mounted skylights are ideal for flatter roofs.
This means curb-mounted skylights are often used in commercial buildings with flat roofs, and deck-mounted skylights are common in homes with steeper roofs.
The slope of your roof is crucial in deciding the type of skylight. Deck-mounted skylights are designed for steeper roofs, where they can be installed seamlessly. They are common in residential settings where the roof design is varied.
Curb-mounted skylights, being suitable for flatter roofs, are a go-to option for commercial buildings or homes with minimal roof pitch. Their design allows for secure installation even on nearly flat surfaces.
Mounting
Curb-mounted skylights are attached to a curb on the roof. Deck-mounted ones need a frame built around them, which can take more time and money.
The installation process for curb-mounted skylights involves attaching them to a pre-built curb, making them somewhat modular.
This ease of installation can be a significant advantage during roofing projects. Deck-mounted skylights, on the other hand, require a frame to be built into the roof, which can be more complex and time-consuming, adding to the overall cost and labor involved in the installation.
Design
Deck-mounted skylights are newer and look sleeker since they blend in with the roof. Curb-mounted skylights are more traditional and stick out more, but they’re cheaper.
Deck-mounted skylights have a modern, low-profile design that blends with the roofline, giving a sleek and contemporary look.
They are less obtrusive and can enhance the aesthetic appeal of a home. Curb-mounted skylights have a more noticeable presence, protruding above the roofline.
While they may not be as streamlined, they offer a practical and cost-effective solution, especially in situations where design is not the primary concern.
Energy Efficiency
Both curb and deck-mounted skylights save energy compared to electric lighting. However, curb-mounted skylights may lose more heat in cold climates.
Both skylight types offer energy-saving benefits by reducing the need for artificial lighting. However, curb-mounted skylights may be less effective in preventing heat loss, especially in colder climates.
This can be a consideration in energy consumption and heating costs. Deck-mounted skylights typically provide better insulation, making them a more energy-efficient choice in areas with harsher winters.
So, if you’re in a warmer place or have a smaller space, a curb-mounted skylight might be best. If you’re in a colder climate or have a larger space, consider a deck-mounted skylight. Both types are great for letting in sunlight.
Deck or Curb Mounted Skylight: Which Is Better?
When choosing between deck-mounted and curb-mounted skylights, the type of roof you have is a big factor. If your roof is flat or not very steep, curb-mounted skylights are a good choice.
But for steeper roofs, deck-mounted skylights are better. If you’re building a new house, you’ve got more options.
Deck-mounted skylights look nicer because they blend in with the roof and aren’t as noticeable from the outside.
They also tend to be cheaper to keep up. Deck-mounted skylights come in lots of shapes and sizes, so you can pick something that really fits your home’s style. You can get them custom-made or choose a standard size to save money.
On the other hand, curb-mounted skylights are a better pick if you need to replace skylights often or are swapping out old ones.
They’re usually more budget-friendly and come in standard sizes, although they don’t have as many custom options as deck-mounted ones.
Just remember, both types of skylights can have drawbacks, like causing fading in furniture or flooring because of the sunlight, or making a room too bright or hot at certain times.
So, think about where the skylight will go and how it’ll affect the room.
Final Thoughts
If you want a skylight that looks good and is energy-efficient, a deck-mounted skylight is a great choice. But, if you’re looking for something more budget-friendly, a curb-mounted skylight is also a good option.
The type of skylight you choose also depends on your roof. Deck-mounted skylights are best for roofs that are sloped.
On the other hand, if your roof is flat or only slightly sloped (less than 14 degrees), a curb-mounted skylight is the way to go.
