A cracked pane in a roof lantern needs prompt attention because the glass is overhead. Send photos from Welwyn Garden City (AL8) and we'll tell you which it is — with the price agreed in writing before any work.
What you might be seeing
- A visible crack in the outer or inner pane
- A starburst from an impact point
- A crack running from an edge (often thermal stress)
Common causes we find
Impact
Hail, falling branches or dropped tools.
Spontaneous breakage
Toughened glass can occasionally break without warning, which is why laminated inner panes are recommended overhead.

Guide prices for cracked lantern glass replacement in Welwyn Garden City
Typical range: £295–£795 ex VAT, which is £354–£954 with VAT, per glass unit. 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?
Most lantern repairs in England need no approval at all. Where a job turns into a replacement, the Building Regulations 2010 apply and we confirm how the work will be signed off before we start. 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.
