We carry out flat rooflight and skylight repairs in Potters Bar and across the EN6 area. Flat rooflights fail in the same places as lanterns: the seal to the upstand, the roof junction and the glass unit.

Is it time for flat rooflight and skylight repairs?
- Water around the rooflight edge
- Misted glass
- Cracked sealant or a lifted membrane at the upstand
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 Potters Bar and the EN6 area
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.
We cover Potters Bar as part of Hertfordshire, about 8 miles from St Albans.

Guide prices for flat rooflight and skylight repairs in Potters Bar
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.
