Flat rooflights fail in the same places as lanterns: the seal to the upstand, the roof junction and the glass unit. Send photos from Hatfield (AL10) 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
- Cracked sealant or a lifted membrane at the upstand
Why it happens
No fall
Flat glass needs a slight fall to shed water; ponding stresses seals.
Upstand detail
As with lanterns, the membrane must be dressed up and sealed.
Covering Hatfield and nearby
Leaf fall from garden trees is the most common cause of eaves overflow on suburban extensions. If your lantern sits near trees, clearing the eaves channel each autumn prevents a lot of drips.

Guide prices for flat rooflight and skylight repairs in Hatfield
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?
In England, like-for-like repairs to a roof lantern don't usually involve building control. A full replacement or a bigger opening is controlled under the Building Regulations 2010, so we set out the route in writing first. 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.
