Factors Affecting Zinc Roofing Costs

Size of Roof

This affects the amount of zinc needed. The above rates would apply to a small domestic roof of 10m2 or less; however, if you were to have a 100 m2 zinc roof these rates would reduce.

Zinc Price Fluctuations

Because zinc is a commodity, it is prone to price changes on a regular basis. Generally, it is affected by both US and Chinese demand, Chinese supply and the price of oil, gas and electric.

Quality of Zinc

The quality of zinc used affects the price. High-quality zinc costs can be upwards of £200/m2

Structure or Design of Project

The above material costs are all fairly standard, but architects and contractors could all design a zinc roof slightly differently, with some designs cheaper than others.

Flat Roof vs Pitched Roof

Flat roofs tend to be significantly cheaper than pitched roofs to install.

Sloped roofs are more dangerous than flat roofs. Furthermore, larger homes may have complex roofs, with sections sloped and sections flat.

Installing a zinc roof on top of a sloped structure costs more than a flat roof installation.

Location

The rates below are for the South East/Outer London Area. You can use the following adjustments depending on where the roofing needs to be done. These are based on the BCIS and Spon indices.

Region% Adjustment
South East (Southampton, Oxford, Kent, Outer London)0
Inner London+4%
South West (Bristol, Exeter)-4%
West Midlands (Birmingham)-10%
East Midlands (Northampton, Nottingham, Leicester)-10%
East Anglia (Cambridge, Norwich, Ipswich)-5%
North West (Liverpool, Manchester)-12%
Yorkshire and Humberside (Leeds, Sheffield)-11%
North East (Newcastle, Sunderland)-10%
Scotland (Edinburgh, Glasgow)-6%
Wales (Cardiff, Swansea)-9%
Northern Ireland (Belfast)-12%

Benefits of Zinc Roofing

Low Maintenance

If you install zinc roofing then you can almost forget about any maintenance costs. Zinc is highly durable and is able to resist continuous corrosion.

When exposed to moisture or carbon dioxide in the air, it forms a protective coating. Even if it is scratched, it can recover given enough time. This isn’t the case for steel. If its coating layer is scratched, the base material rusts over time unless a protective layer is applied.

Even in harsh climates with lots of exposure to rain and wind, you won’t need to worry about ongoing maintenance.

Eco-Friendly

The melting point for zinc is around 420°C. This might sound like a lot, but it’s far lower than steel (1370°C), copper (1085°C) and aluminium (630°C). This means it uses far less energy for production.

It’s also 100% recyclable and roughly 30% of all zinc produced is from recycled sources – and this number is only going to get higher.

Zinc roofs can easily be produced from zinc derived from re-roofed or demolished builds.

Long Lifespan

Zinc is naturally resistant to corrosion, meaning it can withstand all the weather extremes including extreme heat, wind and rain. It also has a much longer lifespan expectancy than a standing seam steel roof.

Properly installed zinc can last over 100 years compared to just 25 to 50 for steel roofs.

Zinc roofs will not rot, split, warp, leak, unlike many other common roofing materials and aren’t susceptible to pest infestation.
