Brighton has a thriving architect-designed extension culture, particularly in the more affluent Victorian and Edwardian streets — Fiveways, Preston Park, the Hove Avenues, Withdean — where homeowners add contemporary rear and side extensions to period properties. Zinc and copper standing-seam roofing is the material of choice for these projects: it reads as clearly contemporary against the period brick, sheds water on the shallow pitches modern extensions favour, and lasts decades. This architect-led market is where most of Brighton's metal roofing demand sits.
Metal roofing and Brighton's conservation areas need careful handling. In the 30+ conservation areas — Brunswick, Kemp Town, Hanover, Montpelier — a visible metal roof on a principal elevation may not be permitted, as it can conflict with the area's historic character. But metal often works on rear extensions not visible from the street, and some conservation officers welcome an honestly contemporary material over a poor imitation of the historic roof. We advise on visibility and what's likely to be permitted, and liaise with conservation where a project needs it — metal roofing here requires knowing the rules, not just the material.
Brighton's marine environment affects metal roofing choice. Zinc performs well in coastal conditions but benefits from correct ventilated detailing to prevent underside corrosion — essential within the salt-laden air near the seafront. Copper is highly durable in marine environments and weathers beautifully. Coated steel needs a quality marine-grade coating to resist salt. We specify the metal and the detailing for the specific coastal exposure of your Brighton project, because a poorly detailed metal roof corrodes from beneath regardless of the metal's headline lifespan.
Metal roofing lives or dies on detailing. Zinc and copper expand and contract significantly with temperature — more so on Brighton's sun-exposed south-facing extensions — so standing seams, expansion provisions and clip fixings must accommodate that movement. The substrate must be ventilated to prevent underside condensation and corrosion. Skip these and the 40–100 year life the metal promises simply isn't achieved. We install to BS EN 988 and FTMRC guidance, with the ventilated substrate and expansion detailing that lets Brighton's metal roofs reach their full lifespan.
Metal roofing appeals to Brighton's notably environmentally-conscious homeowners for reasons beyond appearance. Zinc and copper are highly durable and fully recyclable at end of life, with a lifespan measured in many decades that means far fewer replacements than shorter-life coverings. Their long service life and recyclability give them strong environmental credentials that resonate in a city with a strong green ethos. Metal roofs also pair naturally with the other measures Brighton's eco-minded homeowners favour: standing-seam roofs integrate cleanly with solar PV mounting, and the material suits the contemporary, well-insulated extensions that energy-conscious renovations produce. For homeowners weighing the higher upfront cost of zinc or copper against a concrete or felt alternative, the combination of decades-long life, recyclability and compatibility with solar is often what tips the decision. We're seeing this environmental dimension drive more of Brighton's metal roofing enquiries, particularly on the architect-designed, sustainability-focused extension projects that the city's greener neighbourhoods produce.

Key fact: Zinc roofing installed to BS EN 988 and FTMRC guidance carries a service life of 40–80 years, and copper often over 100 — but both require correct ventilated substrate detailing and expansion allowance, without which the long life the metal promises is not achieved.

“Zinc standing seam on our architect-designed rear extension. The detailing was immaculate — they clearly understood the expansion and ventilation requirements. Looks stunning against the Victorian brick. A real craft job.”
“Copper roof on our contemporary side extension. They advised on the conservation visibility, confirmed it worked on the rear elevation, and delivered a beautiful job. The patina is developing gorgeously already.”
“Standing seam zinc on a dormer and extension. Proper marine-grade detailing for our exposed position, ventilated substrate, the lot. They knew metal roofing properly, not just as a sideline. Excellent.”
Metal roofing in Brighton costs £70–£120 per m² for zinc standing seam, £90–£150 for copper, and £50–£90 for coated steel. A whole extension or dormer project runs £3,000–£12,000 depending on size and complexity. Correct ventilated detailing is included and essential.
It depends on visibility. In Brighton's 30+ conservation areas, a visible metal roof on a principal elevation may not be permitted, but metal often works on rear extensions not seen from the street. Some conservation officers prefer an honestly contemporary material to a poor imitation. We advise on what's likely permitted and liaise with conservation.
Zinc lasts 40–80 years and copper often over 100 in Brighton's conditions — but only with correct ventilated substrate detailing and expansion allowance. Without those, the metal corrodes from beneath and fails early. We install to BS EN 988 and FTMRC guidance so your metal roof reaches its full lifespan.
Copper is highly durable in marine environments and weathers beautifully; zinc performs well with correct ventilated detailing to prevent underside corrosion near the seafront; coated steel needs a marine-grade coating. We specify the metal and detailing for your project's specific coastal exposure, because detailing matters as much as the metal in Brighton's salt air.
Yes — it's the material of choice for Brighton's architect-designed extensions. Zinc and copper standing seam read as clearly contemporary against period brick, shed water on the shallow pitches modern extensions favour, and last decades. Fiveways, Preston Park and the Hove Avenues see a lot of this work on period properties.
Zinc and copper expand and contract significantly with temperature, especially on Brighton's sun-exposed south-facing extensions. Standing seams and clip fixings must accommodate that movement, and the substrate must be ventilated to prevent underside condensation and corrosion. Skip these and the metal's long life isn't achieved — detailing is what makes metal roofing last.
Yes. We roof dormers and whole contemporary extensions in zinc and copper, with all the standing-seam, expansion and ventilation detailing metal demands. Dormers have multiple junctions to detail correctly, and metal is unforgiving of poor work, so it's specialist — which is exactly what we bring to Brighton's metal roofing projects.
