Questions from Seaham
Is a contemporary lantern the same as a flat rooflight?
No. A contemporary lantern still has sloping glass and a ridge or apex; it simply has slimmer frames and fewer bars. A flat rooflight is a single, nearly flat pane of glass on an upstand.
Can I have a contemporary lantern in white?
Yes, though most buyers choose grey or black because the slimmer frame is the point and dark frames disappear against the sky.
Can you fit a roof lantern in Seaham?
We can quote for fitting where we have cover. Send your postcode and photos of the roof and kerb, and we will confirm before quoting.
Who checks building regulations for a lantern in Seaham?
Your local authority building control team or a registered building control approver. For a lantern in a new extension it forms part of the extension's approval; replacements in existing homes have their own rules.
