Solar Tubes vs Skylights: Which Is Right for Royal Oak Homes?
You walk into your bathroom at 2 PM on a January afternoon and flip the light switch. Again. The room's dark even though it's the middle of the day. You've got the same problem in the hallway, the walk-in closet, maybe the kitchen if you're in one of Royal Oak's older brick Colonials where the original floor plan didn't prioritize natural light.
We've been installing both solar tubes and traditional skylights across Southeast Michigan since 1988, and the question we hear most often is simple: which one should I choose? The answer depends on what room you're lighting, how your roof is built, and what you're willing to spend. Let's break down both options the way we explain them on job sites in Royal Oak, Birmingham, and across Oakland County.
What Solar Tubes Actually Are (And How They Work)
A solar tube — also called a tubular skylight or sun tunnel — is a 10-inch or 14-inch diameter tube that runs from your roof down through your attic and into a room below. Here's how it works:
The top of the tube sits on your roof with a clear acrylic dome that captures sunlight from every angle. Inside the tube, a highly reflective aluminum coating (usually 98% reflectivity or better) bounces that light down through the tube, even around bends if your attic framing requires it. At the ceiling level, a diffuser lens spreads the light evenly across the room.
The entire assembly is about the diameter of a dinner plate where it enters your ceiling. Installation typically takes 2-4 hours because we're only cutting a small hole through the roof deck and drywall, then connecting the tube sections. The roof penetration is small — roughly the size of a standard plumbing vent — which means less structural impact and easier flashing details.
Michigan Installation Note: Solar tubes work particularly well in homes with limited attic access or complex roof framing. We've installed them in 1960s ranch homes where running ductwork would be impossible, and in two-story Colonials where the attic space is tight. The flexible tubing can navigate around trusses, HVAC ducts, and existing attic insulation without major disruption.
Best applications for solar tubes in Michigan homes:
- Bathrooms: Especially interior bathrooms with no windows. A 14-inch tube provides enough light for daytime use without electricity.
- Hallways and stairwells: Long, narrow spaces where a traditional skylight would look awkward or require major structural work.
- Walk-in closets: The small ceiling footprint doesn't interfere with shelving or hanging space.
- Laundry rooms and pantries: Utility spaces that benefit from natural light but don't justify the cost of a full skylight.
The limitation is light spread. A solar tube delivers a concentrated column of light directly below the diffuser. It won't fill a large living room or kitchen the way a skylight does. Think of it as replacing a single overhead light fixture, not illuminating an entire space.
Traditional Skylights: The Full Picture
A traditional skylight is a window installed in your roof. The opening is typically 2 feet by 4 feet (24" x 48") or larger, depending on the manufacturer and your room size. You're looking at two main types:
Fixed skylights don't open. They're purely for light. The glass is sealed into a frame that mounts to your roof deck, with flashing integrated around all four sides to keep water out. These are the most common and the most affordable skylight option.
Vented skylights open manually with a crank or pole, or electronically with a remote control. We install these in kitchens and bathrooms where homeowners want ventilation as well as light. The vented models cost more — usually $500-$1,200 more than a comparable fixed unit — but they add functionality, especially in a steamy bathroom or a kitchen that gets hot during summer cooking.
Installation method matters in Michigan. We use curb-mounted skylights on most projects. A curb is a wooden frame (typically 2x6 or 2x8 lumber) that we build on top of your roof deck, raising the skylight 4-6 inches above the roofline. This elevation is critical for water drainage and snow shedding. Michigan gets heavy snow loads, and a curb-mounted skylight sheds snow and ice far better than a deck-mounted unit that sits flush with the roof.
The glass itself has come a long way. Modern skylights use double-pane, low-E coated glass with argon gas fill — the same technology you'll find in quality replacement windows. The low-E coating reflects infrared heat back into your home during winter and blocks solar heat gain during summer. U-factors (heat loss) typically range from 0.30 to 0.50, which is decent but not as tight as a well-insulated wall or ceiling.
Michigan residential building code requires skylights to meet specific impact resistance standards, especially if you're in a wind zone near the lakes. We typically install tempered or laminated glass that meets ASTM E1996 standards for safety glazing. If the glass ever breaks — from a falling branch during a summer storm, for example — it crumbles into small, relatively harmless pieces instead of large shards.
Cost Reality: Solar Tubes vs Skylights in Southeast Michigan
Here's what we've been charging for installations across Macomb, Oakland, and St. Clair counties over the past few years. Your actual cost will vary based on roof pitch, accessibility, and whether we're working around existing roof damage or outdated flashing.
Solar Tube Installed Costs
- 10-inch diameter tube: $500-$800 installed, including flashing, diffuser, and labor
- 14-inch diameter tube: $750-$1,200 installed
- Add-ons: Electric light kit (for nighttime use) adds $150-$250; dimmer control adds another $100-$150
Most homeowners in Royal Oak and Birmingham choose the 14-inch tube. The light output difference between 10-inch and 14-inch is significant — roughly 40% more light — and the cost difference is only $200-$400. If you're already cutting a hole in your roof, go bigger.
Skylight Installed Costs
- Fixed skylight (22.5" x 46.5"): $1,500-$2,500 installed, including curb, flashing, and interior finishing
- Fixed skylight (24" x 48" or larger): $2,000-$3,200 installed
- Vented skylight (manual): $2,200-$3,800 installed
- Vented skylight (electric/remote): $3,000-$4,500 installed
- Add-ons: Blinds or shades (manual) add $200-$400; motorized blinds add $500-$800
The installed cost includes building the curb, cutting the roof deck opening, installing the skylight unit, flashing it properly with ice-and-water shield and step flashing, insulating around the curb, and finishing the interior drywall shaft. If your ceiling is 8 feet and your attic is 4 feet above that, we're building a light shaft through the attic to connect the skylight to your ceiling. That's carpentry, insulation, and drywall work — it's not a 2-hour job like a solar tube.
Long-Term Cost Consideration: Skylights require more maintenance than solar tubes. The flashing needs inspection during roof replacement projects, and the seals around the glass can degrade over 15-20 years. Solar tubes have fewer failure points — the dome is one-piece acrylic, and the tube itself doesn't have seals that can leak. We've seen 20-year-old solar tubes still performing perfectly, while skylights from the same era often need resealing or replacement.
Light Output and Performance Comparison
This is where the differences become obvious. Light output isn't just about brightness — it's about how the light spreads, how it performs in different weather, and how it affects the room's usability.
Solar Tube Light Output
A 14-inch solar tube delivers roughly 200-300 watts of equivalent light on a sunny day — about the same as three or four 75-watt incandescent bulbs. That's plenty for a bathroom, hallway, or closet. The diffuser lens at the ceiling spreads the light in a roughly 10-12 foot diameter circle, with the brightest spot directly below the tube.
On overcast days — which we get a lot of in Michigan from November through March — light output drops to about 30-40% of full sun performance. You'll still get usable light, but you might need to flip on a supplemental fixture for tasks like shaving or applying makeup. The electric light kits some manufacturers offer solve this problem by adding an LED ring around the diffuser that kicks in when natural light drops below a certain threshold.
One advantage of solar tubes in Michigan winters: because the dome is designed to capture light from all angles, it performs better than a flat skylight when the sun is low on the horizon. From November through February, the sun never gets very high in the sky here. A solar tube's dome captures that low-angle light more efficiently than a flat glass skylight.
Skylight Light Output
A 24" x 48" skylight delivers significantly more light — equivalent to 600-1,000 watts on a sunny day, depending on glass type and orientation. More importantly, it floods a much larger area. You're not getting a concentrated column of light; you're getting broad, even illumination across a 15-20 foot space.
Skylights also provide visual connection to the outdoors. You see clouds moving, tree branches, stars at night. That psychological benefit matters, especially in rooms where you spend significant time. A kitchen skylight changes the feel of the space in a way a solar tube doesn't.
The downside is heat gain and loss. Even with low-E glass, a skylight is a thermal weak point in your roof assembly. In summer, you're bringing in solar heat during the hottest part of the day (which is why we recommend skylights with built-in or aftermarket shading). In winter, you're losing heat through the glass, especially if the skylight is on a north-facing roof slope where it never gets direct sun to offset the heat loss.
We've measured attic temperatures in homes with south-facing skylights, and the difference is measurable. On a 90-degree July day, the attic space directly below an unshaded skylight can be 10-15 degrees hotter than the surrounding attic. That heat radiates down into your living space, making your air conditioner work harder. Proper attic insulation around the skylight shaft mitigates this, but it's still a factor.
Installation Complexity and Roof Impact
From a contractor's perspective, these are very different installations. The complexity affects not just cost, but also how much disruption you'll experience and what risks you're taking with your roof's waterproofing.
Solar Tube Installation Process
We start in the attic, marking the location where the tube will penetrate the ceiling. Then we go up on the roof and mark the corresponding spot on the roof deck, making sure we're not cutting through a rafter or truss. The actual roof opening is 10-14 inches in diameter, depending on tube size.
After cutting the hole, we install the flashing assembly — a metal or plastic collar that integrates with your existing shingles. We use ice-and-water shield around the penetration (mandatory in Michigan to prevent ice dam leaks), then shingle over the flashing so water sheds properly. The dome mounts on top of the flashing.
Inside the attic, we connect tube sections (they're usually 2-foot segments that snap together) and run them down to the ceiling. If we need to bend around an obstruction, we use flexible tubing or angled elbows. At the ceiling, we cut the drywall opening, install the diffuser ring, and you're done.
Total time: 2-4 hours for a straightforward installation. We've done them in as little as 90 minutes when the attic is wide open and the roof pitch is moderate. The mess is minimal — some drywall dust in the room below, and we're hauling tools and materials through your attic, but we're not tearing out framing or rebuilding ceiling sections.
Skylight Installation Process
This is a full day's work, sometimes two days if we're building a complex light shaft or dealing with unexpected framing issues.
We start by framing the ceiling opening — typically we're cutting out drywall and adding headers between ceiling joists to create a structural opening. Then we go into the attic and build the light shaft, which is a framed box that connects the ceiling opening to the roof opening. The shaft walls get insulated (usually R-19 or R-21 fiberglass batts) and then drywalled on the inside.
On the roof, we're cutting a much larger opening — 24" x 48" or bigger. We're cutting through roof decking, removing shingles in a 4-foot radius around the opening, and building a curb from dimensional lumber. The curb gets flashed with step flashing on the sides, a head flashing at the top, and a sill flashing at the bottom. We integrate ice-and-water shield around the entire perimeter.
The skylight unit mounts to the curb with screws and sealant, then we shingle back over the flashing. Inside, we finish the drywall shaft, tape and mud the seams, prime and paint. If you want the shaft angled to spread light better (called a "splayed" shaft), that's additional carpentry work.
The roof penetration is significant. You're removing 8-12 square feet of roof deck and replacing it with a skylight assembly. Done correctly with proper flashing and sealant, it's fine. Done poorly — and we've seen plenty of hack jobs across Oakland County — it's a guaranteed leak point within 5-10 years. This is why choosing an experienced contractor matters more for skylights than for solar tubes. We're CertainTeed Master Shingle Applicators, which means we've been trained on proper flashing details and we warranty our work.
Which Option Works Better for Your Royal Oak Home
After 35 years installing both, here's how we guide homeowners through the decision:
Choose a Solar Tube If:
- You're lighting a small to medium space: Bathrooms, hallways, closets, laundry rooms, pantries — anywhere under 120 square feet where you need functional light but not architectural drama.
- Budget is a primary concern: You want natural light for under $1,000 installed.
- Your roof or attic has complications: Low pitch, complex framing, limited attic access, or you're trying to avoid cutting through a truss or rafter. Solar tubes are far more flexible in placement.
- You're in a multi-story home: Running a 10-inch tube from a second-floor ceiling up through the attic and out the roof is straightforward. Building a skylight shaft through two stories is expensive and disruptive.
- You want minimal maintenance: Fewer moving parts, fewer seals, less to go wrong over 20+ years.
Choose a Skylight If:
- You're lighting a large, primary living space: Kitchens, living rooms, master bedrooms, home offices — anywhere you want dramatic, room-filling light and a view of the sky.
- Ventilation matters: A vented skylight in a bathroom or kitchen provides both light and airflow, which a solar tube can't do.
- You want architectural impact: Skylights change the character of a room. They make small spaces feel larger and dark spaces feel open. That psychological benefit is worth the extra cost for many homeowners.
- You're already doing major roof work: If we're replacing your roof or doing significant siding work, adding a skylight is more cost-effective because we're already up there with materials and labor.
- Resale value is a consideration: In Royal Oak's competitive real estate market, a well-placed skylight in a kitchen or master bath is a selling point. Solar tubes are functional but don't have the same "wow factor" during showings.
Combining Both Options: We've done plenty of projects where homeowners install a skylight in the kitchen or master bath for maximum impact, then add solar tubes in secondary bathrooms and hallways for cost-effective lighting. This hybrid approach gives you the best of both worlds — architectural drama where it counts, practical lighting everywhere else.
Royal Oak-Specific Considerations
Royal Oak has a mix of housing stock — 1920s bungalows, 1950s-60s ranches, 1980s-90s colonials, and newer construction. The age and style of your home affects which option makes more sense:
Historic homes (pre-1950): Many of these have steep roof pitches (8/12 or steeper) and limited attic space. Solar tubes work well here because they don't require building a long light shaft. Skylights can be challenging because the steep pitch makes flashing more complex, and building codes may require additional structural support around the opening.
Ranch homes (1950s-1970s): These typically have low-pitch roofs (4/12 to 6/12) and wide-open attics. Both solar tubes and skylights install easily. The decision comes down to room size and budget. We do a lot of solar tubes in ranch-style hallways and bathrooms, and skylights in kitchens and family rooms.
Two-story colonials (1980s-present): These often have cathedral ceilings in living rooms or master bedrooms — perfect candidates for skylights. The higher ceilings mean more dramatic light spread and better visual impact. Solar tubes work well in second-floor bathrooms and hallways where you're running a short distance from ceiling to roof.
If you're unsure which option fits your home, we're happy to come out for a free consultation. We'll look at your roof pitch, attic access, room layout, and budget, then give you an honest recommendation. Sometimes the answer is obvious; sometimes it's a toss-up and comes down to personal preference. Either way, we've installed enough of both across Southeast Michigan to know what works and what doesn't.

Frequently Asked Questions
Yes, solar tubes work year-round in Michigan. The dome design captures low-angle winter sunlight more efficiently than flat skylights. On overcast days (common November through March), light output drops to about 30-40% of sunny-day performance, but you'll still get usable natural light. Snow accumulation on the dome is rarely an issue — the dome's curved shape sheds snow quickly, and the dark color absorbs enough heat to melt light snow cover. We've installed hundreds across Southeast Michigan and haven't had issues with winter performance.
Most skylights are designed for roof pitches between 3/12 and 12/12. Below 3/12 (very low pitch), water drainage becomes problematic and manufacturers won't warranty the installation. Above 12/12 (very steep), installation is difficult and may require custom flashing solutions. The ideal range is 4/12 to 8/12, which covers most homes in Royal Oak and Oakland County. If your roof is outside this range, a solar tube is often the better choice — the smaller penetration and simpler flashing work on nearly any pitch.
Quality solar tubes typically last 20-25 years with minimal maintenance. The dome is one-piece acrylic (no seals to degrade), and the reflective tubing doesn't wear out. The main failure point is the flashing around the roof penetration, but if installed correctly with ice-and-water shield and proper integration with your shingles, it should last as long as your roof. We've seen 20-year-old solar tubes still performing perfectly. When you replace your roof, we'll reflash the solar tube as part of the roofing project — it's a 30-minute job.
No, but poorly installed skylights do leak, often within 5-10 years. The leak points are almost always flashing failures — inadequate ice-and-water shield, improper step flashing integration, or sealant that degrades in Michigan's freeze-thaw cycles. When we install skylights, we use curb-mounted designs with full perimeter ice-and-water shield and metal step flashing integrated into the shingle courses. We've installed skylights that are 15+ years old with zero leaks. The key is hiring a contractor who understands Michigan-specific flashing requirements, not someone who learned to install skylights in Arizona.
Skylights generally add more perceived value, especially in kitchens and master bathrooms where they create architectural impact. Real estate agents in Royal Oak and Birmingham tell us that a well-placed skylight is a talking point during showings — it makes rooms feel larger and more upscale. Solar tubes are functional and appreciated by homeowners, but they don't have the same "wow factor." That said, neither option typically returns 100% of its cost at resale. Think of them as quality-of-life improvements that make your home more enjoyable to live in, with modest resale benefit as a bonus.
Yes, but it's more complicated. We've installed solar tubes in second-floor rooms of homes where the attic is finished living space, or in single-story homes with cathedral ceilings and no attic. The tube runs through the roof cavity between rafters, and we access it from the room below and the roof above. It requires more precision in placement (you can't move the tube around obstructions like you can in an open attic), and labor costs are slightly higher, but it's definitely doable. We've done dozens of these installations across Southeast Michigan.
Annual inspection is smart — check the flashing for any signs of sealant degradation or lifted shingles, especially after heavy snow or ice dam events. Clean the glass interior and exterior once or twice a year (exterior cleaning requires roof access, so many homeowners skip this). If you have a vented skylight, check the operator mechanism annually to make sure it opens and closes smoothly. Every 10-15 years, you may need to reseal around the curb if the original sealant has dried out. When you replace your roof, the skylight flashing gets redone as part of the project. Beyond that, skylights are fairly low-maintenance if installed correctly from the start.
