We carry out flat rooflight and skylight repairs in Chatham and across the ME4 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
- Cracked sealant or a lifted membrane at the upstand
What usually causes it?
No fall
Flat glass needs a slight fall to shed water; ponding stresses seals.
Unit failure
Edge seals fail and the unit mists.
About Chatham and the ME4 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.
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.
Chatham is around 8 miles from Maidstone, and both are within our Kent coverage.
If you're just outside Chatham, we also cover Gillingham (1 mile), Rochester (1 mile), Strood (2 miles).
What should you expect to pay in Chatham?
Most flat rooflight and skylight repairs jobs come in between £195 and £595 ex VAT (£234–£714 including 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.

Flat rooflight and skylight repairs in Chatham: questions
Can you repair a lantern someone else installed in Chatham?
Yes. We repair lanterns whoever fitted them. If yours is still under the installer's warranty, contact them first so you don't affect it.
Which places near Chatham do you cover?
As well as Chatham, we cover nearby Gillingham, Rochester, Strood, Maidstone and the rest of Kent.
Do you replace walk-on rooflight glass?
Walk-on glass is a specialist structural unit; we can measure and specify a replacement from the right manufacturer.
Can you fix a Velux-style roof window?
Our focus is flat rooflights and lanterns; pitched roof windows are a different trade and we'll say so if that's what you have.
