If you're wondering how to calculate metal roof cost, this metal roof cost calculator is the right tool for you. Use it to find the area of your roof, determine how many metal panels you will need, and estimate how much does a metal roof cost. Plan your work in advance and enjoy having your time saved by this handy calculator.

How to use the metal roof cost calculator?

1. Start by answering whether or not you can safely access your roof to take precise measurements.

  • if you answer "YES", input the roof's length and width. The metal roof cost calculator will return its total area.
  • if you answer "NO", you will have to base your calculations on the roof's footprint (which is essentially the area of the roof if it wasn't sloped). Input it's length, width, and pitch. You can refer to our roof pitch calculator if you don't know the pitch's value.
  • NOTE: If your roof has a more elaborate shape, with many sections, calculate the square footages of each of them separately (you can do it with Omni's square footage calculator), and then add them up.

2. The next step is to calculate the measurements of a single roof panel.

  • Input a single panel's length and width to get its area. The calculator will then find the total number of metal panels you will need to buy for your roof.
  • Please note that it is always advised to buy an additional 10% of construction materials for such projects, to account for mistakes and unexpected repairs. You can use our percentage calculator to get this estimated quickly.

3. All that's left is calculating the total costs of the metal panels. Put in the cost of one panel, and the calculator will find your total expense.

How to calculate metal roof cost? Metal roof formulas

Although our metal roof calculator will do all the work for you, we understand that you may feel more confident if you know how to carry out the calculations yourself. Here are detailed instructions on how to calculate metal roof cost on your own.

  • calculating roof area based on roof measurements: roof length * roof width = roof area
  • calculating roof area based on footprint measurements: footprint length * footprint width * roof pitch multiplier = roof area
  • calculating panel area: panel length * panel width = single panel area
  • calculating number of panels to buy: roof area / panel area = panels needed (rounded up)
  • calculating the cost of buying the panels: cost of a single panel * number of panels = total expenses

Metal roof calculator - example of calculations

Let's go through an example to illustrate how our calculator works. In this example, let's assume that we have a roof we cannot access safely, so we're going to have to base our calculations on the footprint. The roof's measurements are:

  • The roof's footprint length is 100 ft100\ \mathrm{ft};
  • The roof's footprint width is 120 ft120\ \mathrm{ft}; and
  • The roof has a pitch of 9:129:12, which has a multiplier of 1.251.25

With those numbers, the calculation is as follows:

Aroof=(100 ft×120 ft)×1.25=15,000 ft2\footnotesize \begin{split} A_{\mathrm{roof}} &= (100\ \mathrm{ft}\times 120\ \mathrm{ft})\times 1.25\\ & = 15,\!000\ \mathrm{ft^2} \end{split}

Let's say we want to buy 16 in×16 in16\ \mathrm{in} \times 16\ \mathrm{in} panels. The area of such a panel is 16 in×16 in=256 in216\ \mathrm{in} \times 16\ \mathrm{in}= 256\ \mathrm{in^2}. By dividing the roof's area by a panel's area and rounding up, we find out that:

If we buy metal panels at $3 a pop, the total cost will be 3$ * 8,438 = 25,314$.

15, ⁣000 ft2256 in2=8,438\frac{15,\!000\ \mathrm{ft^2}}{256\ \mathrm{in^2}} = 8,438

so we need to buy at least 8,4388,438 metal panels.

Common metal roofing types

Metal roofing has many advantages, which is why people often choose it over other materials. It is durable, and can resist pretty much any kind of unpleasant weather, such as rain or snow. The quality and specific characteristics vary depending on the metal. Here are some metals most commonly used for roofing:

1. Copper - long-lasting and eco-friendly (copper roofs are 100% recyclable!), copper has been the go-to roofing material for centuries. It's very soft for a metal, which places copper roofs among the quietest.

2. Zinc - durable and great for forming into different shapes, it's also the most eco-friendly, as its low melting point means that its processing requires as little as ¼ of the energy needed to process other materials.

3. Aluminum - recommended for coastal climates due to its resistance to salt corrosion.

4. Steel - most common in commercial buildings, it's becoming more and more popular among private housing as well. Steel is generally the least expensive, and among the most flexible to use.

FAQ

How much would it cost to put a metal roof on a house?

Assuming the house is 2000 sq ft and the cost per square foot is $10, the metal roof would cost $20,000. To calculate it, follow these steps:

  • Determine the roof area (2,000 sq ft in this case).
  • Multiply the area by the cost per square foot of metal roofing, $10 per square foot, including installation.
  • This results is $20,000.

For an exact cost, consider factors like roof complexity, material quality, and regional labor rates, and consult with a roofing professional.

How do I calculate metal roof cost?

To calculate the cost of a metal roof:

  1. Measure your roof.
  2. Compute the Area - Calculate the total square footage of your roof.
  3. Determine Price per Square Foot - Find out the cost per square foot of your chosen material.
  4. Include Additional Costs - Add installation costs and extra features like coatings.
  5. Calculate Total - Multiply the total square footage by the price per square foot and add additional costs.

Consider factors like roof complexity, material quality, and regional labor rates for an exact cost, and consult with a roofing professional.

How much does a metal roof cost?

The cost of a metal roof typically ranges from $5 to $14 per square foot, including installation. Factors like material type, roof size, and geographic location can influence the price. For precise costs, it's best to consult a roofing professional.
