Parapet gutter blockage and overflow. Lead flashing around chimneys, valleys and abutments is the highest-maintenance element of most roofs in Brunswick Town. Direct seafront, maximum salt corrosion, listed building constraints on all materials We inspect and replace lead to the correct code and specification for local conditions. Regency (1820s-1840s), Welsh slate, lead parapet gutters, conservation area and listed buildings
Direct seafront, maximum salt corrosion, listed building constraints on all materials This means Brighton and East Sussex homeowners should inspect lead every 5 years rather than the 10-year interval that inland guidance suggests. Patching fails within 2-4 years in coastal conditions — full replacement is the right answer in most cases.
Code 4 lead (1.8mm) is standard for most inland applications. For exposed coastal positions — seafront properties, cliff-top locations, south-facing chimney stacks — code 5 lead (2.24mm) provides meaningfully longer service life. We specify code 5 as standard for exposed positions in Brunswick Town.
Strip all existing lead. Clean masonry and tile surfaces. Dress new lead in sections no longer than 1.5m to allow thermal movement. Secure with lead tacks into correct mortar joints. Point all joints with lead mortar. Apply patination oil on completion to establish protective surface chemistry. Inspect from roof level and sign off.

“Flashing lifted out of the mortar joint on our place off Brunswick Terrace. They re-dressed and re-pointed it neatly. Straightforward and honest.”
“Called about damp where the roof meets the wall. Renewed the step flashing, dry ever since. Good communication throughout.”
“Had water around the rooflight after rain at our Brunswick home. They re-led the junction, no more ingress — highly recommend.”
In Brunswick, most lead flashing jobs announce themselves before you ever get on the roof. Lead flashing seals the junctions where the roof meets a wall, chimney, valley or rooflight — and near the coast it corrodes and fails faster than inland.
The signs worth acting on:
When it is not the answer: If existing lead is sound and simply lifted from its chase, re-dressing and re-pointing it is enough — full renewal is not always needed — see our guide.
Hove neighbourhood with Regency (1820s-1840s) housing. The dominant roofing maintenance issue in Brunswick Town: listed building consent, parapet gutter maintenance and Welsh slate matching.
Brunswick Town is one of the finest intact Regency developments in England. Every roof job here requires understanding of Listed Building Consent, lime mortar, Welsh slate sourcing, and the specific failure modes of Regency parapet architecture. General roofers without this experience cause expensive damage.
Every job follows the same clear process — no surprises, no hidden costs, full communication throughout.
Roof-level inspection of all lead flashings — step, apron, valley, abutment. Salt corrosion assessment. Photographs of all findings.
We specify code 4 or 5 lead as appropriate to the position and exposure. We advise on patching vs full replacement — in coastal conditions, full replacement is almost always more cost-effective.
All existing lead removed. Masonry and tile surfaces cleaned. Any underlying mortar or tile damage repaired before lead installation.
New lead dressed in sections no longer than 1.5m. Fixed with lead tacks into correct mortar joints. All joints lapped and dressed. Patination oil applied on completion.
All lead work carries a written 10-year workmanship guarantee. Lead should not be the source of any future roof leak within that period.
Every Brunswick roof is different, but these are the durations we quote most often:
| Job | Typical duration |
|---|---|
| Re-dress & re-point lifted lead | 2–4 hours |
| Renew abutment / step flashing | Half a day |
| Renew chimney flashing & soakers | Half to a full day |
| Rebuild a lead valley | 1–2 days |
| Re-lead a parapet gutter (section) | 1–3 days |
For Brunswick jobs, leadwork is fairly weather-tolerant, but pointing the chase into mortar needs a dry window to cure.
On Brunswick roofs, flashing at low level can be reached from a tower; chimney, valley and parapet leadwork needs scaffold for safe access. Scaffold is specified for chimney flashing, valley rebuilds and any parapet-gutter leadwork — always itemised in your written quote, never a hidden extra, and we arrange it.
In Brunswick, the grade-I Regency terraces of Brunswick Square and Terrace have parapet gutters, slate roofs and strict conservation controls on any work. Pavement scaffold and skip permits go through Brighton & Hove City Council; allow a few working days on streets like Brunswick Square, Brunswick Terrace, Waterloo Street where space is tight.
What you can expect to pay in Brunswick, before your fixed written quote:
| Job | Typical range | Notes |
|---|---|---|
| Re-dress & re-point lifted lead | £150–£300 | Per junction |
| Renew abutment / step flashing | £250–£500 | Per elevation |
| Chimney flashing & soakers | £300–£650 | Per stack |
| Rebuild a lead valley | £550–£950 | Incl. new lead |
| Re-lead parapet gutter (per section) | £600–£1,400 | Code 7/8 lead |
Worked example: A rebuilt lead valley on a Regency terrace on Brunswick Terrace typically runs around £800, including access and waste.
In Brunswick, no deposit on flashing under £500; staged terms on valley and parapet leadwork.
On Brunswick roofs, our workmanship is backed by a written 10-year guarantee, with manufacturer warranties on materials on top — in writing, every time.
If a fault appears in covered work, we come back and put it right — no quibbling, no re-charge.
Focused work at one or two junctions — little mess, with old lead removed and recycled and the area left clean. You do not need to stay home for external work — we just need power and access agreed in advance.
Lead can be dressed in most conditions; we time the mortar pointing of the chase for dry spells so it holds. Locally, Brunswick's seafront frontage takes the full coastal exposure, with salt air and gales attacking the concealed parapet leadwork.
Step flashing replacement costs £80-150 per linear metre. A full chimney flashing set (step, back and front aprons) costs £400-900 depending on chimney size. Valley lead costs £100-180 per metre. Free surveys and written quotes for all work.
Code 4 or 5 lead correctly installed lasts 30-50 years even in East Sussex's coastal conditions. The key is correct installation — sections short enough to move with thermal expansion, correctly secured with tacks, properly pointed.
In East Sussex's conditions, patching is a short-term measure. The surrounding lead has been subject to the same corrosion process and will fail within 2-4 years of any patch. Full replacement is more cost-effective over a 10-year horizon for most Brunswick Town properties.
Damp patches near a chimney breast; white salt deposits (efflorescence) on the lead surface; visible lifting or separation of lead from brickwork; cracking or splitting at dressed edges; water staining on exterior walls below the chimney or abutment.
Age-related lead failure is usually excluded as a maintenance issue. Storm damage to lead flashing — where it has been displaced by high wind — is usually covered. We provide written reports that support insurance claims for storm-related damage.
Patination oil is applied after lead installation to establish the stable protective patina that prevents run-off staining on walls and tiles beneath. It's a standard part of our lead installation — included in all quotes.
