In Derby, as everywhere, most roof lantern leaks start as small, preventable problems: blocked eaves, a lifted capping, a tired seal. Send photos and we'll tell you what we think has failed.

What you might be seeing
- Leaves or moss at the eaves
- You've never had it checked
- The lantern is under trees
Common causes we find
Debris
Leaves and moss block drainage.
Unnoticed wear
Nobody looks at the roof until it leaks.
About Derby and the DE1 area
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.
We also cover nearby Belper (7 miles), Ilkeston (8 miles), Heanor (8 miles).
What should you expect to pay in Derby?
Typical range: £95–£245 ex VAT, which is £114–£294 with VAT, per visit. 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?
Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in England. Replacing the whole lantern or enlarging the opening is different and falls under the Building Regulations 2010; we confirm in writing which route applies before any replacement. 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.

Cleaning and maintenance in Derby: questions

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.
Can you repair a lantern someone else installed in Derby?
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.
What does a maintenance visit cost?
Usually £95–£245 ex VAT per visit depending on size and access, confirmed in writing before the visit.
Can you set up regular visits?
Yes — tell us how often you'd like us to come and we'll confirm the price per visit in writing.
