In Formby, as everywhere, flat rooflights fail in the same places as lanterns: the seal to the upstand, the roof junction and the glass unit. Send photos and we'll tell you what we think has failed.

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.
Unit failure
Edge seals fail and the unit mists.
Roof lanterns in Formby
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.
Urban grime and traffic film dull glass and frames quickly; a clean and seal check makes a tired lantern look and perform much better.
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.
Formby is around 11 miles from Liverpool, and both are within our Merseyside coverage.

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?
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.
