How Roof Pitch Is Calculated
To accurately calculate the area of your roof, you must first determine its slope, or pitch. A roof’s pitch is determined by how much it rises vertically for every foot it runs horizontally. Thus, a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs.
How Many Bundles Of Shingles Per Square
A package of roofing shingles is called a bundle. Laminate or architectural shingles, one of the most common types of roofing shingles, are generally packaged in three bundles per square.
How To Calculate Square Footage
Square footage is area expressed in square feet. Likewise, square yardage is area expressed in square yards. Square meters is also a common measure of area.
Who Uses Roofing Squares
The roofing square size form of measurement is only used within the roofing and construction industries. Though you can use the measurement yourself to try to calculate the cost of re-shingling your homes, such tasks are usually best left to an experienced roofing contractor.
Estimating The Cost Of The Roof
Once you know the area of the roof, you have to decide on the scope of works. Do you want to build the roof from scratch, or maybe replace the old layers? You also need to decide on the finishing material. For example, asphalt shingles will be less expensive than clay tiles.

Estimating Materials Based On Actual Measurements
Measuring each roof plane requires you to actually go onto your roof.

Measure each planes length and width. Record your measurements.
What is the pitch of a roof?
Roof pitch is the measurement of a roof's vertical rise divided by its horizontal run. It is often compared to slope, but is not exactly the same. In the United States, a run of 12 inches (1 foot) is used, and pitch is measured as the rise of the roof over 12 inches. For instance, a 7/12 roof pitch means that the roof rises 7 inches for every 12 horizontal inches. Outside of the U.S., a degree angle is typically used.
How long do shingles last?
Shingle roofs typically have a life span of 15-30 years, while membrane roofs usually last 5-15 years. Although ceramic tile roofs are expensive, they can have a life span of over 100 years.
Does roof pitch affect the area of the roof?
It affects walkability as well as drainage, and roofs in areas of high rain or snowfall tend to have steeper pitches. Roof pitch affects the actual area of the roof. Depending whether the roof area is measured horizontally (possibly from a drawing or photograph), a correction factor is necessary to determine the actual area of the roof.
How big is a roof?
You will need to express this size in terms of square feet. Keep in mind that the average size of a roof is 1,700 square feet, so your total will likely be 10% higher or lower than this figure. Check that your footage measurements are within this range so you can start off on the right foot.
How long does a roof last?
While the average lifespan for a typical roof can be 15-20 years, a long, hard winter or a particularly intense storm can cause lasting damage to a roof. Over time, that damage could really add up. As a result, you might need to calculate an estimate of how much it will cost to replace your old roof with a new one.
What are the factors to consider when estimating a roof?
There are several factors to keep in mind for any estimate: the materials used for the shingles or seam panels, the surface area of the roof (with a measurement typically in squares), and any special features related to the complexity of the roof itself. In addition, details about your unique geography could play a role in the final cost of the project (e.g. if you live in the Northeast or some other region that gets a lot of winter storms).
Can you get discounts on shingle roofs?
This is especially true with shingle roofs (both metal and asphalt). Often, you can get discounts for using certain types of metal or asphalt, so always make sure that you check out these options when running all the numbers. For example, a steel roof will typically cost less than an aluminum roof.
Does a bigger roof cost more?
Calculated quickly on a per foot basis, you can see that a bigger roof will almost always lead to a higher cost. However, there is not a direct 1:1 correlation between surface area and the total cost of the project, as expressed in dollars. Dimensions matter, as do the total amount of feet. This is especially true with shingle roofs (both metal and asphalt). Often, you can get discounts for using certain types of metal or asphalt, so always make sure that you check out these options when running all the numbers. For example, a steel roof will typically cost less than an aluminum roof.
How much solar energy can you generate on your roof?
home, you could fit about 97 solar panels on an average roof – resulting in about 31 kilowatts (kW) of solar panels on your roof. That translates to roughly 57,000 kilowatt-hours (kWh) of solar electricity throughout the year! Considering the average U.S. home uses about 10,600 kWh of electricity annually, this is more than five times the amount you’ll probably need to run your whole home on solar.
How much solar power can you generate based on your roof size?
Below is a chart comparing solar generation potential based on roof size, assuming all of the same metrics as before: 320-watt solar panels, 17.5 square foot panels, and using every inch of roof space available for solar. The last assumption here is important to call out, because in reality, you can’t use every inch of space on your roof for solar. Panels can’t go out to the very edge of your roof, and you’ll more than likely have obstructions like vents or chimneys that take up space as well.
How many hours of sunlight does a solar panel get?
We used 5 hours per day as our average above–here’s how that number (and our end estimate) changes geographically, while still assuming an average roof size of 1,700 square feet and 320 watt solar panels:
What is the production ratio of solar panels?
A solar panel system’s production ratio is the ratio of the estimated energy output of a system over time (in kWh) to the system size (in W). These numbers are almost never 1:1 – depending on how much sunlight your system will get (which is primarily based on your geographic location, but also influenced by things like roof angle and directional orientation), your production ratio will change accordingly. For example, a 10 kW system that produces 14 kWh of electricity in a year has a production ratio of 1.4 (14/10 = 1.4) – this is an entirely realistic production ratio to see out in the real world. In the U.S., production ratios are usually between 1.1 and 1.6.
What angle should solar panels be installed?
To produce the most electricity, solar panels should be installed on a south-facing roof at an angle of about 30°. In our calculations in this piece, we didn’t take that into account. So, while you may live somewhere with almost six peak sun hours (like California), your entire roof almost definitely doesn’t face directly south at the correct angle. So, take all of the calculations here with a grain of salt. Want an accurate estimate for your unique home? Check out our solar calculator, or register for free quotes on our marketplace.
Can you put solar panels on your roof?
You can put all the solar panels you want on your roof, but at the end of the day, they will only produce electricity when the sun shines above. As such, the amount of sunlight that hits your solar panels is a key factor to understand when calculating how much solar energy your roof can generate.
