Assuming the ground is relatively flat, measure the height of your eye from the ground. Take the following steps to measure your roof from the ground:

How to measure roof pitch from ground. Make a outline of your roof on paper. This week i was asked to teach a new solar estimator how to measure a roof from the ground. Then, in the attic, place the end of the level against the bottom of a roof rafter and hold it perfectly level.
This nominal square footage amount is then multiplied by a factor associated with the roof’s pitch. And even flat roofs usually have a little bit of a slope, so you might want to use a roof pitch multiplier once you have your area figured out.) 1. That measurement is the roof’s rise.
Measuring a roof from the ground can be a much safer way to get the information you need to do a roof. Google earth pro was the paid version of google earth (it used to. The roof area (ra) is calculated easily:
In turn number along with a table we provide, or with a simple calculator, it is easy to figure any measurement. If you’d like to know how to convert roof pitch to degrees, check out the chart below: The number you measured with the tape is the roof’s rise or pitch — the amount the roof’s.
So you should essentially see the top edge of the eve or gutter line up with the peak of the roof pitch. The easiest way to measure this section is to divide it up into three different sections: For help determining the area of a sloped roof, see here.
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. How to measure the roof using google earth. We multiply the roof length (c) (which is the sum of building length plus the gable end overhangs of the roof) by the roof width of slope (a) that we just figured out above when we computed the hypotenuse of the roof triangle (that's why we needed the roof rise number).
Determine your roof pitch ( see roofpitch) if you need help. As a tip, if you had hooked the tape measure to the house when you backed away from the wall, you’ll be able to do this without help from someone else! Simple observations made from the ground can give a good approximation of the roof slope.
There are many great benefits to using google earth to measure your roof but nothing is as good as using diy’s satellite roof measurement.the first of which is that you don’t even have to go up on the roof. Using these two figures, we can get a good idea of the shingle roof’s square footage and estimate your asphalt shingles’ needs and costs. As an example, if your overhang is 12 inches, you’ll add 2 feet to the overall length and 2 feet to the overall width of the house.
The first thing you need to do is download and install google earth pro. The third way to measure your roof is from on top of the structure itself. You can calculate the roof pitch by the number of inches that it rises vertically for every 12 inches that it extends horizontally.
First, measure 12 inches from one end of the level and make a mark. How to measure your roof area from the ground. Go all the way around your house and fill in your outline with your measurements making sure to account for overhang.
That is the roof's rise. It is often compared to slope, but is not exactly the same. A more accurate way to calculate the area of the roof than using google earth is to get outside to estimate the roof pitch and the base area of the property.
Extend it upward so it is perpendicular to the level. Measure the inches from the level’s end up to the bottom edge of the rafter. The next step is to measure the pitch (also referred to as the roof slope) of the roof deck.
· make sure you rotate the tape so it is perpendicular to the level. A hip roof split in half fig. Record these values as roof rise over run, with the vertical measurement listed first and the horizontal second.
Also called the roof angle, the roof pitch is defined as the numerical measure of the steepness of a roof, or the ratio of the rise of the roof to the horizontal span. Measure the distance from where you’re standing to the face of the wall you walked away from. To measure a roof, start by measuring the length and width of the building's exterior walls and multiplying them to get the area.
However, if you need to order materials for a job, we still recommend getting a more accurate pitch. Roof pitch is the measurement of a roof's vertical rise divided by its horizontal run. This process is usually rather easy, fast and pretty accurate.
Proceed with measuring the overhang at the fascia or. Measure the vertical distance from roof to level. As you can see, s1 and s3 are the same size, but you still need to document all measurement points to verify your material calculation accuracy.
Knowing that will determine what your roof’s pitch since the run is 12 inches by default. November 3, 2017 at 10:24 am. For instance, a 7/12 roof pitch means that the roof rises 7 inches.
I have done it this way before, but the only issue with this method is that shingles generally have 5 inches revealed instead of 6 inches. Note the vertical distance on the tape measure and write this value down. Here we show how to use a carpenter's folding ruler to obtain the slope and other dimensions of a roof.
How to use a folding rule to measure angles, roof slope, pitch, area and other dimensions: Then, calculate the pitch of the roof by placing a level against it, angling the level so the bubble is centered, and measuring the distance between the end of the level and the roof. The advantage to this option is that it’s the most accurate, but it involves a little more geometry and math than the other options.
This has shed a light on my getting great pictures and how to accurately measure the roof from the ground. The pitch can be as high as 21:12. The basic idea of measuring a roof from the ground may sound ridiculous but it can be done, and done very accurately.
