Flat rooflights fail in the same places as lanterns: the seal to the upstand, the roof junction and the glass unit. Send photos from Amersham (HP7) and we'll tell you which it is — with the price agreed in writing before any work.
What you might be seeing
- Water around the rooflight edge
- Misted glass
- Ponding on the glass (not enough fall)
Why it happens
No fall
Flat glass needs a slight fall to shed water; ponding stresses seals.
Unit failure
Edge seals fail and the unit mists.
About Amersham and the HP7 area
Most inland lantern leaks aren't storm damage; they're usually tired sealant, a lifted capping or blocked eaves drainage. All three are quick to find and fix once you know where to look.
Amersham is around 13 miles from Aylesbury, and both are within our Buckinghamshire coverage.
If you're just outside Amersham, we also cover Chesham (2 miles), Chalfont St Peter (5 miles), Gerrards Cross (6 miles).
What should you expect to pay in Amersham?
Typical range: £195–£595 ex VAT, which is £234–£714 with VAT, per rooflight. Towers or scaffold, where needed, are priced into the quote. Your fixed price is confirmed in writing before any work starts.
Do you need permission in England?
Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in England. Replacing the whole lantern or enlarging the opening is different and falls under the Building Regulations 2010; we confirm in writing which route applies before any replacement. Listed buildings need listed building consent from the local council for alterations, and conservation areas can have extra controls; like-for-like repairs are treated differently from changes, so check with the council's conservation officer first.
