Is it time for flat roof junction and flashing repairs?

  • Splits, blisters or lifted edges in the roof covering by the kerb
  • Missing or loose edge trims and flashings

Common causes we find

Cracked GRP

Fibreglass roofs can crack at the kerb corner where movement concentrates.

Missing trims

Without a trim or flashing to protect the top edge, water gets in behind the membrane.

About Salisbury and the SP1 area

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.

Salisbury is around 34 miles from Swindon, and both are within our Wiltshire coverage.

We also cover nearby Andover (16 miles), Totton (17 miles), Southampton (20 miles).

Guide prices for flat roof junction and flashing repairs in Salisbury

Guide price, per lantern£245–£695 ex VAT£294–£834 inc VAT

Typical range: £245–£695 ex VAT, which is £294–£834 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.
