Trade flat rooflights in Berkshire

Ordering flat rooflights for jobs in Berkshire

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.

Rooflights in England should meet the limiting U-value for rooflights in Approved Document L. The glazing can be specified to suit where the job is, and the U-value is stated on your quote.

Building regulations in England

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.

Before anything goes into production you get a written order acknowledgement with sizes, finishes and handing for every item. Check it carefully, because made-to-measure items cannot be returned if the sizes were wrong.
