See If Deck or Curb Mounted Skylights Are Better for Your Home

Installing skylights can transform any room by allowing beautiful, natural light to pour in. But when it comes to deciding between deck or curb mounted skylights, how do you choose what's best for your home?

We'll look at everything from placement, size, installation and aesthetics to help you make the right decision.

Skylight Basics: Bringing the Outdoors In

Before diving into the deck vs. curb debate, let's review some skylight basics. Skylights are window-like openings installed in ceilings and roofs to allow natural light inside. The benefits go beyond illumination, also enhancing ventilation, aesthetics, and an open, airy feel.

There are a few main types of skylights to consider:

• Fixed skylights that don't open
• Venting skylights that open for ventilation
• Tubular skylights that funnel light through reflective tubes

Skylights come in different shapes like circles, rectangles, and squares. The design you choose can complement your home's style.

Key Differences: Deck vs. Curb Mounted Skylights

Now let's look at how deck and curb mounted skylights differ.

Placement on the Roof

The main distinction between these two types is their placement:

• Curb mounted skylights install on raised "curbs" near the roof edges.
• Deck mounted skylights install directly into the roof deck toward the middle.

Since curb mounts sit high near the roof perimeter, they offer limited space. Deck mounts have more placement flexibility for positioning the skylight.

Size and Shape Options

The location also impacts size. Curb mounts come in more limited sizes, usually 2x2 or 2x4 feet. Their raised edge placement constrains the dimensions.

Deck mounts can be much larger since they take advantage of the open roof space. For wide open rooms and spaces, deck mounts are great for flooding light in. Their custom sizing also allows better views.

Installation Process

Installing these skylight types follows different processes:

• Curb mounts require building a raised curb frame to mount the skylight on.
• Deck mounts need an inner frame built around the roof opening to attach and seal the skylight into.

Deck mounts require very careful roof opening cuts and measurements for a perfect fit. Overall, the deck mount process tends to be more complex.

Aesthetic Impact

Appearance is another key difference. Curb mounted skylights have a higher profile sitting several inches above the roof. Deck mounted skylights sit almost flush with the roof plane.

For contemporary flat roof homes, deck mounts blend more seamlessly. Curb mounts make a bolder statement on any roof type with their raised glass frame.

Comparing Energy Efficiency

An important factor in any skylight decision is energy efficiency. Here's how deck and curb mounts compare:

Heat Loss and Gain

Since curb mounts sit higher off the roof with more air space underneath, they can lose more heat in winter. In summer, the gap allows higher heat gain as well.

Deck mounts have a lower profile flush with the roof, reducing these insulation issues. Proper flashing and sealing during install also improves their efficiency.

Controlling Humidity and Condensation

The curb mount gap can also lead to higher humidity and condensation issues. Mold growth is a risk if excess moisture isn't controlled.

Deck mounts face less ventilation challenges. Careful insulation and vapor barriers during install prevent humidity problems.

Maintenance Requirements

Ongoing maintenance is essential for any skylight. Here are some key factors when comparing curb vs. deck mounts:

• Accessing the skylight glass for cleaning is easier with curb mounts.
• Resealing the edges and flashing should be done every few years, a bit more frequently for deck mounts.
• Drainage systems may need periodic inspection to prevent leaks.

Overall, deck mounts tend to require a bit more vigilance and maintenance work to uphold performance and prevent issues.

Ideal Applications for Each

Now that we've compared the pros and cons, here are some ideal uses for each skylight type:

Curb Mounts

• Smaller skylights to illuminate tight spaces
• Bathrooms and laundry rooms
• Accent skylights for visual interest

Deck Mounts

• Illuminating large, open spaces
• Living rooms, kitchens and hallways
• Maximizing light and views

The number of skylights also impacts the choice. Multiple deck mounts work well spaced across a large expanse. For one or two skylights, curb mounts offer flexibility.

Design Tips for Maximizing Your Skylights

Proper placement and layout enhances how skylights interact with your space:

• Align over areas where you want the light focused, like kitchen counters.
• Place near interior walls to reflect and diffuse light wider into the space.

Strategic positioning prevents glare and makes the most of your skylights. Complementing interior paint colors, window coverings, and lighting layouts also create a welcoming ambiance.

Consulting a Professional for Your Project

While we've covered the key comparisons, analyzing your home's unique needs is crucial for deciding between deck vs. curb mounted skylights. A skylight expert can:

• Evaluate your roof structure, layout and climate.
• Recommend suitable skylight types and features.
• Maximize energy efficiency with proper installation.

Investing in a professional assessment will ensure your new skylights enhance your home for years to come.

We hope this overview has illuminated the main differences between deck and curb mounted skylights. Evaluating placement, size, install complexity, aesthetics and efficiency helps determine which type suits your home best.

You can enjoy the benefits of natural light and gorgeous views with smart planning and professional installation.
