In Stevenage, as everywhere, many uPVC roof lanterns have an aluminium core with uPVC cladding and cappings. Send photos and we'll tell you what we think has failed.

What you might be seeing
- Yellowed or brittle end caps
- Green algae along the bars
- Leaks at the ridge or eaves
Common causes we find
UV ageing
uPVC components become brittle and crack after years of sun.
Clip failure
Clip-on cappings can lose their grip and lift.
Covering Stevenage and nearby
Lanterns in central England see a bit of everything — summer sun that ages seals and end caps, autumn leaf fall that blocks eaves, and frosty mornings that bring condensation. A yearly check covers all three.
From St Albans to Stevenage is roughly 12 miles — all part of the Hertfordshire area we cover.
We also cover nearby Hitchin (5 miles), Letchworth Garden City (5 miles), Welwyn Garden City (7 miles).
What should you expect to pay in Stevenage?
Typical range: £175–£595 ex VAT, which is £210–£714 with VAT, per lantern. 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.
