In Belper, 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.

Signs you need flat rooflight and skylight repairs
- Water around the rooflight edge
- Misted glass
- Ponding on the glass (not enough fall)
Why it happens
Upstand detail
As with lanterns, the membrane must be dressed up and sealed.
Unit failure
Edge seals fail and the unit mists.
Roof lanterns in Belper
Snow and ice sitting at the eaves can block a lantern's drainage and push water back under the glass as it melts. If your lantern leaks after a thaw rather than after rain, tell us — it points to the eaves and kerb.
From Derby to Belper is roughly 7 miles — all part of the Derbyshire area we cover.

What should you expect to pay in Belper?
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.

Flat rooflight and skylight repairs in Belper: questions
Do you need to visit to price flat rooflight and skylight repairs?
Not always. Clear photos are often enough for a guide price. Where the cause isn't obvious, a visit to inspect and water-test is charged from £145 ex VAT, confirmed before we come.
Which places near Belper do you cover?
As well as Belper, we cover nearby Ripley, Heanor, Alfreton, Derby and the rest of Derbyshire.
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.
