We carry out flat rooflight and skylight repairs in Harwich and across the CO12 area. Flat rooflights fail in the same places as lanterns: the seal to the upstand, the roof junction and the glass unit.

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 Harwich and the CO12 area
Even in drier areas, one heavy downpour with blocked eaves is enough to overflow a lantern indoors. Clearing the eaves channel is the simplest prevention there is.

What should you expect to pay in Harwich?
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.
