Flat rooflights fail in the same places as lanterns: the seal to the upstand, the roof junction and the glass unit. Send photos from Exeter (EX2) and we'll tell you which it is — with the price agreed in writing before any work.
What you might be seeing
- Misted glass
- Ponding on the glass (not enough fall)
- 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.
Roof lanterns in Exeter
Western and upland parts of the UK get more rain and more wind-driven rain than the east, and that's what finds weak cappings and blocked eaves first. Lanterns here benefit from a check of the bars on the most exposed face and a clear eaves channel before winter.
Near the coast, salt in the air is hard on aluminium finishes and fixings; washing the frame occasionally and touching in chips keeps corrosion away.
Close by, we also cover Exmouth (9 miles), Tiverton (12 miles), Newton Abbot (14 miles).
What should you expect to pay in Exeter?
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.
