How to Estimate Roofing Materials

To do this, measure the length and width of each plane on the roof, including dormers. Then, multiply length x width to get the square footage of each plane. Finally, calculate your roof’s total square footage by simply adding the square footage of each of the planes together.

Roof replacement cost for different roofing materials

The type of roof material you are replacing plays a large role in the pricing of your roof replacement. Most roofing contractors will provide a quote with the cost per square of materials, where one roofing square is equal to 100 square feet. Different roofing materials all have a different price per square.

The following table outlines the roof replacement cost ranges for different roofing materials:

Table 1: Roof replacement costs by roofing material

Roofing materialAverage cost per square footAverage total replacement cost*
Asphalt shingles$3.40 – $5.95$5,840 – $10,100
Metal roofing$6.00 – $24.50$10,245 – $41,640
Tile roofing$6.30 – $12.30$10,665 – $20,900

Slate roofing$23.49 – $31.77$39,925 – $54,020

Tips for Estimating Roof Shingles

The first step to figuring out how many shingles you need is calculating the square footage of your roof. Going up on your roof is dangerous, so our method relies on measuring from the ground. This calculation will be pretty rough, but will give you a ballpark figure. Don’t let the math scare you – it’s actually pretty straightforward.

To find the square footage of your roof:   

  1. Outside your home, measure the length and width of your house. Measure from eave to eave, rather than corner to corner, to account for the roof’s overhang.
  2. If your house isn’t rectangular, measure the length and width of each section.  
  3. Multiply the length and width of each section to get the square footage. If your house is rectangular – you’re already done!
  4. Add the square footages of all sections together to get the total square footage of the roof.

Now, take your total square footage and divide it by 100. 

This will tell you how many “squares” your roof is. You’ll use the number of squares to figure out how many shingles you’ll need.

What should be covered in a roofing estimate template?

Generally speaking, this is what should to include in an estimate for a roofing job:

  • Total roof cost with detailed sections outlining labor and material costs.
  • Instructions from the customers and a description of all the work to be done.
  • Warranty information on the work done and the materials used.
  • How long the estimate is good for.

It’s a good idea to go over every estimate item with potential customers to confirm they understand exactly what’s being done and any conditions on that work.

If you bid on commercial roofing projects, the general contract owner may require specific information not mentioned here. Generally speaking, a list of what to include in your roofing bid is provided during the bidding process.

Calculating the Area of a Complex Roof

Areas of complex roofs with many hips and valleys take the most time to calculate. To get started, make a rough sketch of the roof. To simplify things, break down the sketch into rectangles and right triangles and then take as many measurements of the roof as you can to match the sides of the rectangles and triangles on the sketch.

Square lines off eaves edges or ridges can be determined by using visual cues from the existing roof. These will help you measure the lengths of the sides of the rectangles and triangles. For example, the cutout slots on shingled roofs run perpendicular to the eaves, and nail rows in sheathing are very close to square as well. While it can be challenging sometimes to get accurate measurements, don’t be too concerned and round lengths to the nearest 6 in.

When your sketch is filled in with measurements, determine the size of the roof area. The area of a rectangle is length multiplied by width, while the area of a right triangle is the length of the two sides that meet at the 90-degree corner multiplied together and divided by two.

How do you measure a roof cut?

To find your roof’s total square footage:
  1. Measure the length and width of each plane on the roof (including dormers) then multiply length times width.
  2. Add the square footage of each of the planes together.

What’s the pitch of a roof?

Roof pitch (or slope) tells you how many inches the roof rises for every 12 inches in depth. An Example of a roof pitch would be a “6/12 pitch” which means that the roof rises 6 ” for every 12″ inward towards the peak (or ridge).
 

What are the most common roof pitches?

The most commonly used roof pitches fall in a range between 4/12 and 9/12. Pitches lower than 4/12 have a slight angle, and they are defined as low-slope roofs. Pitches of less than 2/12 are considered flat roofs, even though they may be very slightly angled.

Here’s our step-by-step guide for measuring the total roof area for installation:

  1. Step 1: Start by sketching out a top-down view of your home’s roof. …
  2. Step 2: Measure the length of your roof. …
  3. Step 3: Next, figure out the width of the metal that you’re installing. …
  4. Step 4: Repeat Step 3 for the other side of the roof.

How do you measure a roof edge?

Measure out from the face of the wall below the fascia or rafter tails to a point that aligns with the outer edge of the roof. Multiply this measurement by the length of the roof from end to end, and add this to the first result. Double the result to determine the total area of the roof at both sides.

How do I estimate the cost of a metal roof?

Divide the length of your roof by the width of the metal. In our example we will use 24-inch standing seam roofing, so we will divide 360 inches by 24, which equals 15. This is the number of metal panels needed for one side of the roof.

How much is a 24 gauge metal roof?

The actual price you’ll pay depends on multiple cost factors that are based on your roof and the contractor you hire. For a one-story house with a basic up and over roof with no penetrations and no valleys, you can expect a 24 gauge steel standing seam metal roof to cost around $12.00 per square foot.
 

Common Metal Roof Sheet Sizes

Roofing panels come in many styles and dimensions with different overlap dimensions. The most common lengths are 8′, 10′, 12′, and 16′, however many distributors will cut to length.

The most common widths are 24″ and 36″ exposed, but the actual width of the panel will be larger to accommodate an overlap. Each style of panel is unique and may have a different actual width and exposed width.

Metal roofs are beautiful and very durable. When installed correctly, they can last a very long time with little maintenance. See our other roofing resources for more roofing calculators and tools.

Metal Roofing Costs at a Glance

  • Average labor costs: $350-$400 per 100 square feet
  • Average labor costs, seam roof: $500 per 100 square feet
  • Corrugated metal sheets: $180-$250 per 100 square feet
  • Aluminum sheets: $325-$575 per 100 square feet
  • Copper sheets: $1,400-$2,200 per 100 square feet
  • Average total material costs: $4,875-$8,625
  • 2,000-square-foot metal roof cost: $8,000-$60,000
  • Compare to 2,000-square-foot asphalt roof: $6,000-$7,500

Replacing your roof can be inconvenient and expensive, so it’s hardly surprising that durability is one of the most important deciding factors for many homeowners. Metal roofing systems are gaining popularity thanks to their stylish appearance and long lifespans. However, metal is also one of the most expensive roofing options, so it’s important to understand the costs involved before replacing your existing roof with a metal one.

Types of Metal Roofing

There’s a lot to choose from when it comes to metal roofs. If you are not decided yet on the best metal roofing for your home, here’s a list of the common metal roofs out there.

  • Corrugated metal roof
  • Copper Roofing
  • Aluminum roofs
  • Metal slate roofs
  • Standing seam metal roofs
  • Tin Roofing
  • Steel roofs
  • Zinc metal roof
  • Metal tile roofs

Steel roofing is a common choice for property owners because they produce roof surfaces that effectively shed snow and rain. When you choose this option, you should hire a professional roofer to install them properly. Otherwise, the results will be noisy when it rains.

How do I estimate the cost of a metal roof?

Divide the length of your roof by the width of the metal. In our example we will use 24-inch standing seam roofing, so we will divide 360 inches by 24, which equals 15. This is the number of metal panels needed for one side of the roof.

Is it cheaper to get a metal roof or shingles?

With that in mind, a metal roof will always be more expensive than shingles. … For example, an architectural shingle roof (the most commonly used shingle) will cost around $4.76 per square foot, while a standing seam metal roof will cost around $15.00 per square foot.

How much does it cost to put a metal roof on a 1700 square foot house?

These metal panels cost between $1 and $2.50 per square foot for the raw materials, or between $5.50 and $11.50 for materials plus installation costs. For a 1,700-square-foot roof, the total metal roofing cost comes out to about $9,350 to $19,500.

Is a metal roof better than a shingle roof?

Metal roofing is durable and routinely lasts 2-4 times longer than shingles. Homeowners like the idea of buying only one more roof in their life instead of potentially several. Metal roofing outperforms shingles in cases of hail and other severe weather events. 

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 the cost of buying the panelscost of a single panel * number of panels = total expenses

Average Cost of Metal Roof Installation

Once you have the materials, then you need to actually install your roof – or more accurately, have it installed by a team of professional roofers.

The costs of installing your metal roof will vary depending on your location, your property, and the type of roof that you are installing, but installation costs are important to account for since they will affect the total price of your new metal roof.

Metal roofing tends to be more expensive to install than asphalt or wood shingles since it is not simply nailed to the top of the roof but rather built on top of a breathable synthetic underlayer, prefabricated trim, fashioning, and requires the installation or customization of pipe boots and roof vents.

This of course increases the overall cost of materials as well as the expertise necessary to do the job – roofers in your area or metal roof contractors who can handle metal roofing with the appropriate skill tend to be on the higher end, cost-wise.

Also, keep in mind that smaller orders of metal roofing material (or any other roofing material) tend to cost a bit more per square foot than larger orders.

Ordering through your roofing contractor can be one way to save on your new roof since they likely have the connections to buy at a bulk rate or can get an industry discount.

Another important factor to consider when you are pricing out metal roofing is the sustainability aspect; while metal roofing might be initially more expensive than other materials, it may last longer and you might not require many metal roof repairs or be less likely to require a total replacement than other types of roofing materials.

Plus, metal roofing can often be the most energy-efficient selection, saving you money on heating during the winter and air conditioning in the summer.

How Much Does a Metal Roof Cost?

Is it cheaper to get a metal roof or shingles?

With that in mind, a metal roof will always be more expensive than shingles. … For example, an architectural shingle roof (the most commonly used shingle) will cost around $4.76 per square foot, while a standing seam metal roof will cost around $15.00 per square foot.

Is a metal roof better than a shingle roof?

While asphalt shingles can withstand fire, metal roofs offer the best resistance. And though it’s commonly believed hail can easily dent a metal roof, that’s a myth. Metal roofs are more efficient at handling common hail impacts than asphalt shingles. Winner: Metal roofing.

Is it OK to put a metal roof over shingles?

In almost every case, the answer is yes, you can lay down a new metal roof over an existing shingle roof. This is one of the many reasons metal roofs keep growing in popularity – their installation doesn’t require completely tearing off the existing roof, which is a time-consuming and expensive job.

Metal Roof Cost: How to Calculate the Cost of a Metal Roof

 

 

You may know the size of your home, and you may even know the square footage of your roof—but calculating the cost of a metal roof is a little more complicated. Roofing prices change with the demand for materials and the cost of acquiring them, and labor costs vary regionally and seasonally. As a base calculator, use the following formula:

**  Materials + Labor and Installation in My Area + Overhead = Total Cost of Metal Roofing Near Me

Each of these three components should make up one-third of your project cost.

As you begin calculating, keep in mind that roofers use a unique unit of measure called a roofing square to calculate material prices, equivalent to 100 square feet (a 10-foot by 10-foot square). This calculation will itemize the total material cost for that section, so the number of squares needed to cover your roof will drive the rest of the expenses. To accurately estimate, plan on over-ordering material by 5 to 20 percent to account for waste on cuts and any pattern matching. Labor costs will vary, so plan to collect multiple estimates with itemized cost lists before you choose. Overhead will include costs such as shipping, tools, permits, and insurance.

We can now apply the same premise to metal roofing panels with a better understanding of life cycle costs. The table below highlights that life cycle costs are a game-changer in any cost comparison between shingle and metal roofing.

How to Manually Measure a Roof

To manually measure a roof without the help of aerial measurement reports, you must visit a job site and climb onto the roof to take precise roofing measurements by hand. Here are the 6 steps to get a manual roofing measurement.

 
  1. Measure the width and length of each plane of the roof (including dormers), and then multiply those numbers to get the correct figure for the square footage of that area.
    Example: Plane 1 (A x B): 50’ x 20’ = 1000 sq ft
    Plane 2 (A x C): 50’ x 20’ = 1000 sq ft
  2. Note any skylights, chimneys or other parts of the roof that would not require materials. You can subtract those measurements from your total area.
  3. Add together the calculated square footage of each surface to get the figure for total square footage of the roof.
    Example: Plane 1 (1000 sq ft) + Plane 2 (1000 sq ft) = 2000 sq ft
aerial roof measurement
  1. After determining the total square footage of the roof, you must calculate the pitch of the roof. Measure the vertical distance (rise) over a 12 inch horizontal segment (run).
    Example: The rise of this roof is 5”.
  2. Write down these numbers as the vertical measurement listed first and the horizontal measurement recorded second so you can find rise over run.
    Example: The rise over run of this roof is 5” over 12”.
  3. When you have the total square footage and rise over run of the roof, you can calculate the roof squares to determine how much materials are needed to cover the roof. To calculate the number of squares on a roof, you need to divide its total square feet by 100.
    Example: 1000 sq ft / 100 = 10 squares

With those roofing measurement figures, you can then estimate the roofing supplies needed for a job.

How do you find the sq ft of a roof?
