Planning and building regulations for Washington
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.
Planning-wise, a lantern on a new extension is judged as part of that extension, while one added to an existing roof can fall outside permitted development if it stands more than 150 mm proud.
Building regulations in Washington 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 Washington
Do I need an upstand for a roof lantern?
Yes. Lanterns are designed to sit on an upstand, never directly on the roof deck.
Who makes the upstand weatherproof?
Your roofer, by dressing the roof membrane up the outside of the upstand. The lantern then sits over it.
Is it worth having solar-control glass in Washington?
With the midsummer sun about 58.5° high at noon, roof glass in Washington gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
Can you fit a roof lantern in Washington?
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.
