In-Depth Product Reviews

1. VELUX FS M08 2004D Fixed Skylight – Best Overall

When it comes to residential skylights, VELUX is the name that consistently comes up among professionals, and for good reason. The FS M08 is my top recommendation for homeowners who want a “set it and forget it” solution that prioritizes quality, energy efficiency, and peace of mind.

What sets this apart is the glass. VELUX uses what they call Comfort-PLUS glass, which is a dual-pane, argon-filled unit with a Low-E coating. In plain English, this means it’s incredibly well-insulated, keeping your home warmer in the winter and cooler in the summer. It blocks over 80% of the sun’s fading UV rays, protecting your furniture and floors. Critically, it features laminated safety glass, meaning if it ever breaks (from a severe hailstorm, for example), the glass fragments will adhere to an interlayer, much like a car windshield. This is a huge safety feature, especially for skylights installed over living areas.

The build quality of the frame and the pre-attached deck seal provide a robust weather barrier. When installed with the corresponding VELUX flashing kit (which is essential), the company offers a 10-year “No Leak” warranty. In my experience, a properly installed VELUX skylight will last much, much longer without issue.

What We Like

  • Superior energy efficiency with Comfort-PLUS glass
  • Laminated safety glass prevents falling shards
  • Industry-leading “No Leak” warranty with flashing kit
  • Excellent build quality and durability
  • Pre-finished white wood frame requires no painting

What We Don’t Like

  • Premium price point
  • Flashing kit must be purchased separately

2. FAKRO FWP-V U3 P2 Egress Roof Window – Best for Safety

If you’re converting an attic into a bedroom or living space, building codes in most U.S. jurisdictions require an “egress” window for emergency escape. The FAKRO FWP-V is specifically designed for this purpose. Unlike a typical top-hinged or center-pivot window, this model is side-hung and opens to a full 90 degrees, creating a large, unobstructed opening that meets egress requirements.

Beyond safety, this is simply a fantastic roof window. The P2 anti-burglary laminated glass offers incredible security and peace of mind. The frame is constructed from beautiful, close-grain pine wood that’s pressure-treated for longevity. It feels incredibly solid. A handle at the bottom makes it easy to open and close, and it features two passive micro-ventilation slots, allowing for air circulation even when the window is fully closed.

Installation is straightforward for a professional, and FAKRO’s system is well-regarded. While its primary purpose is safety, it doesn’t skimp on features, offering excellent light transmission and solid thermal performance. This is the go-to choice for any occupied attic space.

What We Like

  • Meets building code requirements for emergency egress
  • Opens to a full 90 degrees for easy escape/access
  • High-security P2 laminated glass
  • Beautiful solid pine wood construction
  • Passive ventilation feature

What We Don’t Like

  • More complex and expensive than fixed skylights
  • Side-hung design may not be ideal for all roof layouts

3. Sun-Tek Tube 10-Inch Tubular Skylight – Best for Small Spaces

What if you want to brighten up a windowless bathroom, a dark hallway, or a walk-in closet? A traditional skylight is often overkill and impractical for these spaces. This is where the tubular skylight, or “sun tunnel,” shines. The Sun-Tek 10-inch tube is a brilliant and cost-effective solution.

The concept is simple: a small, high-impact acrylic dome on your roof captures sunlight and funnels it down a highly reflective, flexible tube to a diffuser lens mounted in your ceiling. The amount of light it delivers is genuinely surprising—a 10-inch tube can illuminate a 150 sq. ft. room with the equivalent of about three 100-watt bulbs on a sunny day. It’s a soft, diffused light that feels completely natural.

From an installation perspective, these are far less invasive than a full skylight. Because they are designed to fit between rafters, there’s no need to cut structural joists. This makes the DIY potential much higher for a handy homeowner. The kit comes with everything you need, including the dome, tubing, diffuser, and hardware. For bringing light to the dark interior corners of your home, there’s no better value.

What We Like

  • Perfect for lighting up small, interior rooms
  • Far less expensive and invasive to install than traditional skylights
  • Surprisingly effective at transmitting light
  • DIY-friendly installation for experienced homeowners
  • Energy Star qualified and very efficient

What We Don’t Like

  • Doesn’t provide a view of the sky, only light
  • Light output is dependent on weather/sunlight

4. RecPro RV Skylight 14×22 Kit – Best for RVs

Roof windows aren’t just for houses! Your RV or camper can benefit immensely from the natural light and feeling of openness a skylight provides. However, you can’t just use a residential model. RV skylights need to be lightweight, impact-resistant, and designed to handle the vibrations and stresses of being on the road. The RecPro kit is a top seller for a reason: it’s a perfect, all-in-one replacement solution.

This kit includes both the outer dome and the inner garnish (the trim piece). The outer dome is made from a single piece of thermoformed polycarbonate, which is incredibly tough and resistant to cracking from impacts or sun exposure. The smoke tint is a great feature, as it lets in light without creating a harsh glare or excessive heat inside the RV.

Installation is about as simple as it gets for this type of project, making it a very popular DIY upgrade for RV owners. The standard 14″ x 22″ size fits the rough opening of most common RV shower and galley skylights. For replacing an old, yellowed, or cracked dome, this RecPro kit is a no-brainer. It’s an affordable upgrade that makes a huge difference to the interior environment of your rig.

What We Like

  • Durable, impact-resistant polycarbonate construction
  • Includes both inner and outer components for a full replacement
  • Standard size fits most RVs
  • Very easy to install for DIYers
  • Excellent value for the price

What We Don’t Like

  • Does not provide significant insulation
  • Sealant/putty tape must be purchased separately

5. SIG Skylights Fixed Skylight with Tempered Glass – Best Value

Let’s be honest: premium skylights can be expensive. If you’re working with a tighter budget but still want a quality product that won’t cause problems, the SIG Fixed Skylight is an outstanding value proposition. It delivers the most important features you need without the premium price tag of bigger brand names.

The standout feature here is that you get double-pane, tempered, Low-E glass at this price point. This is a significant step up from the cheap acrylic “bubble” skylights you might see at big-box stores. The Low-E coating helps with energy efficiency, and the tempered glass is strong and safe. This is a curb-mount model, meaning it’s designed to be installed on a site-built curb (a wooden frame) on the roof. This is a very common and reliable installation method.

The frame is made from thermally-broken extruded aluminum, which means there’s a barrier to prevent heat transfer, and it’s finished with a durable powder coating. While it may not have the brand recognition or the same no-leak warranty as a VELUX, for a homeowner or contractor looking for a solid, well-made, energy-efficient skylight without breaking the bank, this SIG model is tough to beat.

What We Like

  • Excellent price for a double-pane, Low-E glass skylight
  • Durable thermally-broken aluminum frame
  • Tempered glass for strength and safety
  • Simple, robust curb-mount design
  • Made in the USA

What We Don’t Like

  • Requires a well-built curb for installation
  • Lacks the advanced features and warranties of premium brands

Expert Buyer’s Guide: How to Choose the Perfect Roof Window

Choosing a roof window is a long-term investment. My goal is to give you the expert knowledge you need to make the right choice once. Here’s what you absolutely must consider.

Fixed vs. Ventilating: More Than Just a Breeze

This is your first major decision. Fixed skylights (like the VELUX and SIG models) do not open. They are purely for letting in light. This makes them simpler, less expensive, and generally less prone to potential issues down the line. They are perfect for cathedral ceilings and areas where you just want to conquer darkness. Ventilating (or venting) skylights can open, either manually with a crank or electronically via a remote. They are ideal for bathrooms and kitchens to exhaust moisture and odors, or in bedrooms to let in cool night air. This works in tandem with your home’s overall ventilation system, such as a ridge vent. They are more expensive and have more moving parts, but the added function is invaluable in the right location.

Glazing and Glass Explained (This is CRITICAL!)

The glass is the most important part of your skylight. Don’t cheap out here.

  • Glass vs. Plastic (Acrylic/Polycarbonate): For a home, always choose glass. Plastic is for RVs and sheds. Glass offers vastly superior clarity, scratch resistance, and longevity.
  • Double-Pane & Argon-Filled: This is the standard for energy efficiency. Two panes of glass are separated by a space filled with an inert gas like argon, which is a poor conductor of heat. This keeps your home’s temperature stable.
  • Low-E Coating: A “Low Emissivity” coating is a microscopically thin, transparent layer of metal oxide. In winter, it reflects heat back into your home. In summer, it reflects the sun’s heat away, which helps answer the common question of whether metal roofs make your house hotter. A Low-E coating is a non-negotiable feature for any climate.
  • Tempered vs. Laminated Glass: Tempered glass is heat-treated to be about four times stronger than regular glass. When it breaks, it shatters into small, pebble-like pieces. Laminated glass (like in the VELUX) has a plastic interlayer. When it breaks, the pieces stick to the interlayer. For skylights high above living spaces, laminated glass is the safer choice.

The Unsung Hero: Flashing Kits

I can’t stress this enough: a skylight is only as good as its installation, and the installation is only as good as the flashing. A flashing kit is a series of metal pieces that integrate the skylight with your roofing material (shingles, tile, metal) to create a waterproof seal. Sometimes this involves using a quality roofing tape or even building a roof cricket to properly divert water. ALWAYS buy the specific flashing kit made by the manufacturer for your model of skylight and your type of roof. Mixing and matching or trying to fabricate your own is the #1 cause of leaks.

Professional Installation vs. DIY

Unless you are a roofer or a very experienced contractor, I strongly advise professional installation for a residential skylight. This is not a simple window installation. You are cutting a hole in the most critical protective barrier of your home, an activity that should always be done with a roof harness for safety. A professional will know how to properly frame the opening, build a curb, install the flashing and ice/water shield, and integrate it seamlessly with the roofing. Using the right tools, from a proper roof ladder to the best roofing hammer, is essential. A mistake can lead to catastrophic water damage. The cost of a professional is well worth the peace of mind.

The exceptions are tubular skylights and RV skylights, which are much more forgiving and designed with DIY installation in mind.

Frequently Asked Questions (FAQ)

1. What’s the difference between a skylight and a roof window?

In the U.S. market, the terms are often used interchangeably. Historically, a “skylight” referred to an out-of-reach, fixed unit (like on a cathedral ceiling), while a “roof window” referred to an in-reach, openable unit (like in an attic room). Today, manufacturers use both terms, so it’s more important to look at the specific features (fixed vs. venting) than the name.

2. How much does it cost to have a roof window installed?

This varies wildly by location, roof complexity, and the type of skylight. As of 2025, you can expect to pay anywhere from $800 to $2,500+ for professional installation, *in addition* to the cost of the skylight itself. A simple replacement is on the lower end, while a new installation that requires cutting rafters and framing is on the higher end.

3. Do all roof windows eventually leak?

This is a common fear, but the answer is NO. A modern, high-quality skylight from a reputable brand like VELUX or FAKRO, installed correctly with the proper flashing kit by a competent professional, will not leak. Leaks are almost always the result of improper installation, failed flashing, or damage to the roof around the skylight, not a failure of the unit itself.

4. How long do roof windows last?

A quality glass skylight should last 20-30 years or even longer. The seals between the glass panes are often the first component to degrade over decades. If you notice persistent condensation between the panes, it’s a sign the seal has failed and it’s time to consider a replacement. Regular roof check-ups can identify issues early; understanding the cost of a roof inspection is a good first step.

5. Can you install a roof window on any roof?

Almost any roof, but not all. Most skylights are designed for pitched roofs with a slope between 15 and 85 degrees. Installation requires special care depending on the material, including knowing if you can walk on a tile roof or a metal roof without causing damage. Some homeowners even wonder if you can paint a metal roof to match a new aesthetic. Installing on a flat or very low-slope roof is possible but requires a special curb and flashing technique to create enough of a slope for water to run off properly.

Final Verdict: The Best Investment for Your Home

Adding a roof window is more than an aesthetic upgrade; it’s an investment in your quality of life. The daily dose of natural light can have a profound impact on your mood and the overall feel of your home.

For the absolute best combination of performance, safety, and long-term reliability, the VELUX FS Fixed Skylight is my top recommendation. It’s the professional’s choice for a reason. However, if your needs are different—whether it’s for safety, a small space, or an RV—any of the excellent options on this list will serve you well. Choose the right product for your specific needs, insist on correct installation with the right gear like proper roofing shoes, and get ready to enjoy a brighter home.
