A Gerard roof costs less than you’d expect

Most people are pleasantly surprised when they’re told the price of a Gerard pressed steel roof. When you compare ‘like with like’ a Gerard roof is very reasonable.

All inclusive price

With a Gerard roof, everything is included in the quoted price, including purlins and roofing underlay. With long-run roofing, these items may not be included in the quoted price – be sure to ask.

Reduced overall building costs

Installing a Gerard pressed steel roof instead of a heavyweight concrete or clay tile roof can help to reduce overall building costs. Fewer trusses, rafters and bracing elements are required with a Gerard roof.

No added costs for coastal areas

Gerard roofs don’t require any special anti-corrosion treatment if your home is near the sea. With a long-run roof, the building code demands either a special marine rated coating (which costs extra) or a more expensive grade of steel.

Price Guide – a rough idea of ‘how much?’

There are many variables that affect the cost of a roof, so we can’t give you an exact price without knowing more about your home.

The variables that affect cost are explained in detail below the chart.

Factors that influence the cost of any roof

New home or re-roof:

Re-roofing has additional costs, such as removal and disposal of the old roof.

Building use:

Residential buildings use standard underlay. Commercial and institutional buildings will require fire resistant underlays, which cost more.


Larger, more complex roofs are generally more expensive; however the cost per square metre can reduce with a larger roof.

Product choice:

The profile, finish and colour you choose can affect cost, because some choices are more expensive than others.

Design complexity:

As a rule, the more corners your roof has, the greater the cost. Roof style also influences cost.


Freight costs and proximity to your nearest installer will affect cost.

Site access:

Unusual sites may require special equipment for access.

Roof height:

Some sites will require more scaffolding and edge fall protection during installation.

Roof pitch and rafter spaces:

Roofs with a higher pitch or larger rafter spaces generally cost more. With two-storey homes, the cladding and pitch govern the type of flashings required for the top storey.

Extra complexities:

Chimneys, skylights, narrow hips and raking cuts will increase roofing costs.
