Flat rooflights for March homes
A single near-flat pane on an upstand: minimal, low and discreet.
In midsummer the noon sun stands about 60.9° high over March, so roof glazing gets the full strength of it. That is why solar-control glass is worth considering on larger lanterns here.
- Fixed or electric opening versions
- Single glazed unit with a slight fall
- Sized to your upstand

Planning and building regulations for March
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 March 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 March
Can I walk on a flat rooflight?
Only if it is a walk-on rooflight designed for foot traffic. Standard rooflights are not designed to be walked on.
Are flat rooflights cheaper than lanterns?
Usually, size for size. They use one glass unit and a simple frame.
Is it worth having solar-control glass in March?
With the midsummer sun about 60.9° high at noon, roof glass in March gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
Do I need planning permission for a roof lantern in March?
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.
