What You Need To Complete The Installation

A flat roof skylight needs the correct flashing to stay weathertight. Contact our team to confirm the matching flashing kit for your roof type and pitch. For an installation beyond arm’s reach, the VELUX ZCT 300 control rod operates the skylight from floor level (confirm availability with the supplier). Browse the VELUX manual flat roof skylight range or the wider Velux Skylights range, and check the Skylight Accessories category for installation extras.

Frequently Asked Questions

How does the manual opening work?

The sash opens and closes with a smooth handle mechanism, so you can control the airflow without any electrics. For an installation within easy reach, the handle gives direct control. For higher ceilings, the VELUX ZCT 300 control rod operates the skylight from floor level; confirm with the supplier whether it is required for your ceiling height.

What roof pitch does it suit?

The VCM is designed for flat or low-pitch roofs up to about 15 degrees, with the correct flashing installed. The flashing is chosen for your roof material and pitch, so confirm the roof build-up with the supplier before ordering.

Does it need a flashing kit?

Yes. A flashing kit is required to make the skylight weathertight against the roof, and it is sold separately. Flat roof installations need the flashing matched to the roof membrane and any slope so water sheds cleanly away.

Does it come with an insect screen?

Yes. A pre-installed insect screen is included, so when the sash is open for summer ventilation, mosquitoes and flies stay out. It is a standard part of the manual opening unit.
