Where Design Meets Lasting Performance
VELUX skylights bring smart design and natural light together to create spaces that feel cleaner, brighter, and more alive. Whether you’re remodeling your kitchen, finishing an attic, or designing a quiet reading nook, a fixed skylight with a solar-powered shade gives you total light control with no wiring required. It’s beauty with purpose—engineered for energy savings, easy installation, and a difference you’ll notice every single day.
Installing a skylight is a proven way to increase resale value and curb appeal. Buyers love the look of natural light and open, airy rooms—and homes with skylights often photograph better and stand out in listings. A VELUX deck mount skylight offers a sleek, modern finish and helps highlight a home’s best features. Plus, energy-efficient glass and light-controlling shades provide year-round comfort that today’s buyers expect.
Flashing
VELUX flashing kits are engineered to protect against leaks and integrate seamlessly with a wide range of roofing materials.
• Step Flashing (EDL): Ideal for asphalt shingles, wood shakes, and slate roofs up to ½" thick.
• High-Profile Flashing (EDW): Built for tile roofs thicker than ¾".
• Metal Roof Flashing (EDM): Designed for standing seam and corrugated metal roofing.
• Copper Flashing (EDL Copper): A premium option for upscale or historic roof systems.
Using an approved VELUX flashing kit is essential for activating the full 10-Year No Leak Warranty.
Roof Pitch
VELUX deck-mounted skylights are suitable for roof pitches between 14° and 85°, making them the preferred choice for sloped or pitched roofs where a close-to-the-deck installation is desired.
In contrast, VELUX curb-mounted skylights accommodate pitches from 0° to 60°, offering greater flexibility for flat and low-slope roofs, including many retrofit applications.
Choosing the correct skylight type for your roof pitch ensures proper drainage, weather resistance, and warranty compliance.
Deck Mount
A deck-mount skylight installs directly onto the roof deck, offering a streamlined, low-profile finish that complements modern roofing systems. Ideal for new construction and full roof replacements, deck-mounted skylights are known for their superior energy efficiency and weather-tight performance. Because they sit closer to the roof surface, they help minimize thermal loss and enhance your home’s architectural appeal.
10-Year Hail Warranty
VELUX skylights with laminated Low-E3 glass include a 10-year warranty against hail damage, protecting your investment from unexpected weather events. This coverage ensures the glass won't crack or break due to hailstones, offering long-term peace of mind for homeowners in storm-prone regions. The laminated glass also meets stringent building codes and provides added security and sound insulation.
