Metal & Steel Siding Cost Guide

The average cost to have metal siding installed on a large home would be around $6,000 to $12,000. Metal siding is a more expensive option compared to conventional exterior shingles, brick and clapboard, but corrugated steel does have its advantages. Although expensive, the roof will not need to be replaced for a very long time and so it will pay for itself over the course of the years.

The Costs

  • Minimum Cost of Metal Siding: $4 per square foot

  • Maximum Cost of Metal Siding: $8 per square foot

 A more cost-effective type of metal siding is aluminum, which is more lightweight and easier to install. It does not rust and can be painted, and it is also 100 percent recyclable. However, with aluminum steel, the color can fade from weather exposure and become chalky in appearance. Once the color fades, it is hard to match and therefore requires the whole building to be painted. Also, because of its lightweight properties, it can take on dents more easily. Metal/steel siding usually costs about $20 more than vinyl siding per every hundred square foot. Professional installation on a 1200-1500 square foot home can take around 3 to 5 days to complete, depending on working conditions.

Metal Siding Uses

Metal siding is a popular material used in many factories and industrial buildings. As of recently, many homeowners are also installing metal/steel siding on their homes exteriors because of its durability. Corrugated steel is a popular option because of the wave like design that reinforces the structure. Metal siding is highly durable and protective, standing up to such weather conditions as harsh snow, hail, wind and rains. It is resistant to fire, rot, insects and harsh weather conditions. Hail does not damage metal siding, and corrugated steel has one of the highest resistance rates to hail storms. It is four times more resistant to warping, buckling and thermal expansion than vinyl siding is.

The maintenance levels for metal and steel siding are also minimal. It can be painted, which means the entire facade will not need to be taken down if the owner decides they want to change the color. Steel metal can last more than 20 years and comes in a variety of colors that resist fading. It does not take on the chalky appearance of aluminum but does require a pressure washer for cleaning. One of the downsides of metal siding is that it is susceptible to rust and would need coatings of rust preventing paints to help delay any corrosion. Because of this, it is recommended for use with buildings that are more inland than on the coast.

Advantages of Metal Siding

It also does not contain any type of silica dust, which is a cancer-causing agent, unlike products made from fiber cement. Most companies also offer a hefty warranty that lasts the lifetime of the home. It is also impervious to insects and bugs, which adds to its longevity. Metal reflects sunlight during summer, helping to keep the home cool and is fire resistant. Some additional features are low maintenance, durability, environmental friendliness, as well as the ability to be painted and not buckle or warp.

Disadvantages of Metal Siding

Metal siding may keep the home cool in summer but in the winter it is not as good at absorbing heat and insulating. Heating bills can be higher in homes with metal siding. It is also very heavy, making it difficult to install. It also requires more energy to create and is a non-renewable resource. Corrugated steel siding is usually coated with zinc or other anti-rust properties to ward off corrosion. If painted, the metal should be repainted every few years or once the coatings wear off.

High winds can also create enlarged fastening holes which can allow moisture in and under the surface. Areas that have a history of frequent high winds and rain are probably not the best option for this type of siding. Some additional disadvantages would be its cost, the need to be professionally installed and being prone to rusting.


Metal can be installed in any kind of pattern and also cut to proper length which reduces the need for seaming. Once properly installed, the metal siding should lock out moisture well. Installation should be professionally done because of the heavy weight of the material and the difficulty in cutting. Most companies who install metal siding have a special machine that can manufacture each piece of siding on site to cut precise pieces for the house being fitted. Since metal is seamless after the panels are cut it is simply a matter of fitting each piece to the exterior walls. Methods differ depending on the type of building being worked on, skills of the applicator and type or brand of the siding being used.

Most materials used in installing metal siding include panels, flashing, drip caps, trim, ridges and column covers. Power saws, hacksaws, starter strips and caulk will also be needed for proper installation. Some types of seamless metal siding are customizable and hot dipped for extra galvanization.

To clean metal siding all that is needed is either a pressure washer or garden hose to clean along with a mild non-abrasive detergent. If maintained properly, it can last for many years. Most manufacturers offer warranties of at least 20 to 40 years.
