“How much will a zinc roof cost?” is the first question almost every Surrey homeowner asks us, and it’s a fair one. The honest answer is that it depends on the roof. In this post we explain exactly what it depends on, show you what the published UK price guides say (and why they disagree so much), and explain why zinc often works out well over the life of the roof, even though it costs more than felt or tiles at the start.

We’re The Specialist Roofing Company, a family-run metal roofing firm based in Old Windsor, fitting zinc since 2007. We’re approved installers for VMZINC, RHEINZINK and PREFA, and we work across Surrey.

What drives the cost of a zinc roof

1. Size and shape

The bigger the area, the more zinc and labour you need, but the cost per square metre usually falls as the area grows. A small, fiddly roof such as a bay, a porch or a single dormer costs much more per square metre than a large, simple extension roof, because the time goes into folding edges, corners and junctions rather than laying long trays.

2. Details

Rooflights, chimneys, soil pipes, parapets, valleys and box gutters each need hand-formed zinc work. Two roofs of the same size can be priced very differently because one has three rooflights and a concealed gutter and the other has none.

3. The build-up underneath

Zinc must be laid on a suitable deck with the right underlay, and moisture must never be trapped beneath it. Depending on the roof, that means a ventilated cold roof or a warm roof with insulation above the deck. This part of the job is invisible once the roof is finished, but it decides how long the zinc lasts. Read why ventilation matters beneath VMZINC standing seam.

4. Finish

Natural zinc starts bright and dulls over time. Pre-weathered finishes in blue-grey or dark grey look settled from day one and cost more. If you want a factory colour instead, PREFA aluminium is another option with its own pricing.

5. Access and scaffolding

A single-storey rear extension with side access is quick to scaffold. A three-storey roof on a narrow plot is not. If scaffolding has to stand on a public pavement or road you’ll usually need a licence. The Federation of Master Builders notes that Surrey County Council charges £200 per 28-day period for one (FMB, New roof cost UK, read 3 Oct 2026).

6. What’s coming off

Stripping an old felt, lead or tiled roof, repairing rotten decking and disposing of waste all add to the cost. On older Surrey houses, we often only find out what the deck is like once the old covering is off, so a sensible quote includes a clear rate for any repairs.

7. Planning and design

In a conservation area or on a listed building, you may need drawings and consent before work starts. We supply samples and product data. Your architect’s fees are separate.

Published guides, not our prices

We don’t publish a price list, because every roof is different. For a rough sense-check only, two UK price guides (read on 3 October 2026) say:

  • MyJobQuote puts zinc roofing panels at £110–£140 per m², and notes that London and larger cities usually cost more (MyJobQuote, Metal Roof Cost UK).
  • RoofingCalculatorHQ gives installed 2026 prices for single-storey standing seam zinc, including strip-out and underlay, of £2,200–£3,200 for a 5 m² bay or dormer and £10,500–£15,500 for a 50 m² mansard or large dormer (RoofingCalculatorHQ, Zinc Roof Cost Calculator).

These are other companies’ published figures, not our prices. Guides measure different things, and small roofs cost far more per square metre than large ones, so treat them as a sanity check, not a quote.

Why zinc often pays back over time

  • Very little maintenance. Zinc forms its own protective patina, so it never needs painting, coating or sealing. Like any roof, it benefits from clear gutters and an occasional check.
  • It isn’t replaced as often. A properly designed and installed zinc roof outlasts felt and many other flat-roof coverings by a wide margin. That means fewer replacements, less scaffolding and less disruption over the years.
  • It’s light. On older timbers or garden buildings, zinc can avoid the cost of strengthening a structure that heavier coverings would need.
  • It’s recyclable. Zinc can be recycled at the end of its life without losing quality.

Our work also comes with a 20-year guarantee.

How to compare zinc roofing quotes

When you’re comparing quotes, check that each one names:

  • the zinc manufacturer, finish and thickness
  • the build-up: deck, insulation, underlay and ventilation
  • every detail included, such as rooflights, gutters, flashings and abutments
  • scaffolding, strip-out and waste
  • who actually does the work (our own team does every job, never subcontractors)
  • the guarantee

A cheaper quote that leaves out ventilation or details isn’t cheaper in the end.
