Daylight, Designed Better
From brightening everyday routines to elevating home design, VELUX skylights bring more than just natural light—they bring a better way to live. Built with decades of innovation, trusted globally, and designed to perform in every season, VELUX fixed skylights transform ordinary spaces into open, light-filled environments. Whether installed in a vaulted kitchen or a quiet hallway, a VELUX skylight turns daylight into a design feature—and turns your house into a more comfortable, beautiful home.


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.

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.

Flashing Kit
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.
