Flat rooflights fail in the same places as lanterns: the seal to the upstand, the roof junction and the glass unit. Send photos from Spalding (PE11) and we'll tell you which it is — with the price agreed in writing before any work.

Signs you need flat rooflight and skylight repairs
- Water around the rooflight edge
- Misted glass
- Ponding on the glass (not enough fall)
Common causes we find
No fall
Flat glass needs a slight fall to shed water; ponding stresses seals.
Unit failure
Edge seals fail and the unit mists.
About Spalding and the PE11 area
Sun and UV do more damage than rain on many lanterns here: brittle ridge caps, chalky finishes and hardened gaskets. They're cheap to replace before they let water in.
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.
We cover Spalding as part of Lincolnshire, about 34 miles from Lincoln.

How much should it cost?
Guide price for flat rooflight and skylight repairs: £195–£595 ex VAT (£234–£714 inc 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?
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.
