We carry out flat roof junction and flashing repairs in Hythe and across the SO45 area. The junction where the flat roof covering meets the lantern kerb is a weak point on many extensions.

What you might be seeing
- Splits, blisters or lifted edges in the roof covering by the kerb
- Missing or loose edge trims and flashings
- Ponding on the roof next to the lantern
What usually causes it?
Unbonded membrane
EPDM or single-ply that has come away from the kerb lets water run behind it.
Cracked GRP
Fibreglass roofs can crack at the kerb corner where movement concentrates.
Covering Hythe and nearby
Drier, sunnier parts of the UK are kinder to seals than the wet west, but strong sun ages sealant, gaskets and plastic end caps, and south- or west-facing lanterns can make rooms very warm. Solar control glass and an opening vent help.
From Southampton to Hythe is roughly 3 miles — all part of the Hampshire area we cover.
Neighbouring places we cover include Southampton (3 miles), Totton (6 miles), Eastleigh (8 miles).
What should you expect to pay in Hythe?
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?
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 roof junction and flashing repairs in Hythe: questions
How do I get a price for flat roof junction and flashing repairs in Hythe?
Send a few photos of the lantern and the problem, with your Hythe postcode. We'll reply with a guide price and tell you whether a visit is needed before we can fix the price.
Which places near Hythe do you cover?
As well as Hythe, we cover nearby Southampton, Totton, Eastleigh, Cowes and the rest of Hampshire.
Do you repair the whole flat roof?
We repair the area around the lantern. If the wider roof is failing we'll tell you and can quote, but we won't push a new roof if a local repair will do.
Can you repair a GRP roof without it showing?
Repairs are colour-matched as closely as possible, but new topcoat next to weathered topcoat can look slightly different at first.
