Velux Flashing Systems

A crucial part of our complete system. VELUX flashing systems are designed to shed water without relying on sealants that can break down over time. We offer a variety of flashing systems to ensure a weathertight fit for virtually all roof types and slopes.

Note: Flashing systems are not required for pan-flashed skylights or SUN TUNNEL™ skylights.

Aluminum Step Flashing

ECL step flashing provides a weathertight seal for standard site-built curbs installed on roofs with thin roofing materials such as asphalt or fiberglass shingles. ECL step flashing works with:

  • Curb mounted skylights, such as the VELUX FCM, VCM and VCE skylights.
  • 2x6 or 2x4 site-built curbs made to standard dimensions.
  • Shingles or other low-profile roofing materials on roof pitches from 10° (2:12) - 60° (20:12).

Copper Step Flashing

EDL step flashing provides a weathertight seal for deck mounted skylights or roof windows installed on roofs with thin roofing materials such as asphalt or fiberglass shingles, slate, cedar shingles and shakes*

Each piece of step flashing is interwoven with a layer of roofing material for proper water drainage. No caulk or sealants are needed. Type EDL for skylights is designed for roofs with slopes from 14º (3:12) to 85º (137:12). Type EDL for roof windows is designed for roof pitches required by GPU and GDL.

Biepack Flashing

ECB flashing is to be used in conjunction with a site-built curb and deck mounted skylights in low sloped roof applications.

It is to be applied on simple 2x4 lumber and plywood, and does not require bending.

High Profile Flashing

High profile flashing provides a weathertight seal for standard site built curbs installed on roofs with roofing materials such as Spanish tile.

  • Curb mounted skylights, such as the VELUX FCM, VCM and VCE skylights.
  • 2x6 or 2x8 site-built curbs made to standard dimensions.
  • Tiles or other high-profile roofing materials on roof pitches from 14° (3:12) - 60° (20:12).

Metal Roof Flashing

A VELUX® exclusive, EDM metal roof flashing makes installing skylights in metal roofs a snap. Flashing pieces interlock directly with the roofing material for a fast, weathertight installation and streamlined exterior. A sill apron features pliable pleats that form to the roof. EDM flashing is designed for roof pitches from 14º (3:12) to 85º (137:12).

Skylight Combi-Flashing

EKL combi-flashing is designed to work with multiple deck mounted skylights grouped together on low-profile roofing materials such as shingles and shakes. This flashing system is designed for roofs with slopes from 14º (3:12) to 85º (137:12).

Skylight applications require 4" spacing for over-and-under configurations. 2½" to 12" spacing in ½" increments is required for side-by-side configurations. Note: skylight spacing dimensions will vary from actual gutter width - see installation instructions.

Roof Window Combi-Flashing

Roof window EKL systems are designed for use with required GPU and GDL roof pitches.

Roof window applications require 4” spacing for both over-and-under and side-by-side spacing.

This modular system allows easy installation of an unlimited number of units closely together to dramatically transform interior spaces with natural light.

Note: Skylight spacing dimensions will vary from actual gutter width, see installation instructions.
