ECL step flashing provides a weathertight seal for curb mounted skylights 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).
