In Lowestoft, as everywhere, each glazing bar on a roof lantern has a top capping that clamps the glass onto gaskets. Send photos and we'll tell you what we think has failed.

What you might be seeing

  • A capping visibly higher than its neighbours
  • Rattling or whistling in wind
  • End caps missing at the bottom of a bar

What usually causes it?

Gasket shrinkage

Rubber gaskets shrink back from the ends over time, leaving a gap at the ridge or eaves.

Damage

Ladders, window cleaning or someone stepping on a lantern can bend a capping or unclip it.

Covering Lowestoft and nearby

Sun and UV do more damage than rain on many lanterns here: brittle ridge caps, chalky finishes and hardened gaskets. They're cheap to replace before they let water in.

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.

From Ipswich to Lowestoft is roughly 38 miles — all part of the Suffolk area we cover.

Neighbouring places we cover include Great Yarmouth (9 miles), Norwich (22 miles), Stowmarket (37 miles).

How much should it cost?

Guide price, per lantern£165–£395 ex VAT£198–£474 inc VAT

Typical range: £165–£395 ex VAT, which is £198–£474 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?

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.

Can a capping just be clipped back on?

Sometimes, if nothing underneath has failed. We check the gaskets first, because clipping a capping over a perished gasket doesn't stop the leak.
