Flat rooflights for Welwyn Garden City jobs
A flat rooflight should not be laid dead flat. Water needs to run off, so the upstand is built to a slight fall or the unit has one built in.
The inner pane is laminated so that if the glass breaks it stays in place rather than falling into the room below.
- Double or triple glazed
- Made to your upstand size
- Minimal or hidden aluminium frame
- Built-in fall or set on a sloped kerb for drainage

Measuring tip
Flat rooflights need a fall so water runs off. Build the upstand to a slight slope or use a unit with a built-in fall, and give us the upstand size.
Regulations for jobs in Welwyn Garden City
Replacement rooflights and roof lanterns in England should meet a U-value of 2.2 W/m²K under Approved Document L. A lantern in a new extension is covered by the extension's own building regulations approval. Replacing a glazed or polycarbonate conservatory roof with a solid roof usually takes the conservatory out of the exemption, so building control approval is normally needed.
