Black roof lanterns for Seaham homes
RAL 9005 jet black for crisp contrast and steel-look interiors.
In midsummer the noon sun stands about 58.6° high over Seaham, so roof glazing gets the full strength of it. That is why solar-control glass is worth considering on larger lanterns here.
- Usually no surcharge as a stock colour
- Black or white inside
- Pairs with steel-look screens and doors

Planning and building regulations for Seaham
England's Approved Document L caps the U-value of new or replacement rooflights in existing homes at 2.2 W/m²K, calculated with the glass horizontal.
Lanterns on permitted development extensions are part of the extension's height limits. Adding one to an existing roof is different: over 150 mm of projection can mean a planning application.
Building regulations in Seaham are checked by your local authority building control team or a registered building control approver. Replacing a rooflight in an existing home is building work. Installers registered with a competent person scheme can self-certify; otherwise building control must be involved.

Questions from Seaham
Does black get hotter?
The frame surface does, but the effect on the room is small next to the choice of glass.
What black is it?
Usually RAL 9005. If your doors are a different black, such as RAL 9004 or 9011, give us the code.
How quickly can I get a roof lantern in Seaham?
Stock sizes are typically ready in 5–10 working days, made-to-measure in 3–4 weeks, plus delivery. Your quote gives the date for SR7.
Do I need planning permission for a roof lantern in Seaham?
Often not, but it depends on the roof, the property and whether it is listed or in a conservation area. Check with your district, borough or unitary council before ordering.
