    I bought this skylight to replace my 23-year-old Velux model. While the original skylight wasn’t showing any signs of failure, I decided to upgrade it as part of a full reroofing project for the house. Central Skylights provided great assistance in identifying the right replacement for my needs.

    Thank you for assisting us with replacing our damaged skylights. The last winter was particularly harsh, and the old bubble-style skylights couldn’t withstand it. The new Velux flat glass units not only feel more durable but also look significantly better

Flashing and roof compatibility

VELUX EDW flashing for tiled roofs

For suitable tiled roofs, pair the VSS C04 with VELUX EDW flashing. EDW flashing is designed for profiled roofing such as concrete or terracotta tiles and similar profiled roof materials.

Custom flashing for metal roofs

For metal roof profiles, use the matching VELUX Custom Flashing C04 Skylight for FS, VS, VSS and VSE 550 x 980mm skylights. Confirm whether your roof is corrugated, TrimDeck, Kliplok or another metal profile before ordering.

  • Minimum 15° pitch is required for VSS pitched roof skylights.
  • The matching C04 custom flashing is used for FS, VS, VSS and VSE 550 x 980mm skylights.
  • VELUX EDW suits tiled roofs and some low-profile metal roofs such as corrugated/spandek, but is not suitable for Klip-Lok or Trimdek profiles.
  • Custom Colorbond flashing is commonly preferred for corrugated, TrimDeck and Kliplok metal roof installations.
  • Confirm roof pitch, rafter spacing, roof profile, water flow and skylight orientation before ordering.

Suitable blinds for VSS C04

VELUX FSCH/FSLH blinds for VS, VSE and VSS

Choose the VS/VSE/VSS C04 550 x 980mm size option when ordering a blind for this skylight.

  • FSCH Solar Honeycomb Blackout: stronger room darkening, heat reduction and glare control.
  • FSLH Solar Translucent: softer filtered daylight while reducing glare.
  • Solar remote operation: convenient light control without a hard-wired blind power connection.

When to add a blind

Add a blind if the skylight is above a bathroom, bedroom, home office, kitchen bench, robe or west-facing space where you want better privacy, heat control or softer daylight.

Compare VELUX C04 options

VSS C04 is the solar opening model. Depending on the room and budget, compare the fixed, manual and electric C04 alternatives.

Fixed daylight

VELUX FS C04 Fixed Skylight

Best when you want natural daylight only in the same C04 size and ventilation is not required.

Manual opening

VELUX VS C04 Manual Opening Skylight

Best when you want daylight and fresh air with simple manual operation.

Electric opening

VELUX VSE C04 Electric Opening Skylight

Best when you prefer a hard-wired electric opening skylight in the same C04 size and power is already planned nearby.

Installation and planning notes

Solar power and control

The VSS C04 includes a solar panel, concealed battery-operated system, wireless keypad, rain sensor and insect screen. The solar panel recharges the battery used for opening and closing.

Roof and shaft planning

Installation planning should consider roof pitch, rafter spacing, roof profile, water flow, flashing type, shaft depth, plaster finishing and roof access for lifting and positioning.

Supply only

Supply-only is useful for builders, roofers and renovators who already have trades and roof installation arranged.

Supply and install

Homeowners often prefer full installation where the job requires roof preparation, flashing, shaft framing, plastering and product setup.
