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 Blackburn

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.
