Curb Mount
A curb-mounted skylight is designed to sit on a raised curb structure built on the roof, making it a flexible option for both new installations and replacements.
Curb-mounted models are ideal for flat or low-slope roofs and can simplify installation—especially when replacing older units or working with thicker roofing materials.

Roof Pitch
Compatible with roof pitches from 0:12 to 20:12 (0° to 60°).
Ideal for flat and low-slope roofs, or where an existing curb is already in place. A great choice for retrofits, replacements, and homes with roofing materials like torch-down, TPO, modified bitumen, or tar & gravel.

Flashing
ECL Low-Profile Flashing – Suitable for low-slope and flat roofs, commonly used with membrane or rolled roofing systems.
ECW Step Flashing – For use with shingle and shake roofs (minimum pitch 3:12). Designed to integrate with typical roofing profiles and provide weathertight protection around curb-mounted skylights.
EMW Metal Roof Flashing – Specifically made for standing seam and corrugated metal roofs, ensuring a custom fit and secure seal.
Why is Flashing important?
VELUX 10-Year Installation Warranty
VELUX flashing is designed to perfectly integrate with VELUX skylights, creating a weathertight seal that protects your home from leaks and water damage. By using VELUX-certified installers and genuine VELUX flashing, you can be confident that your skylight is installed correctly and to the highest standards.
