Satellite Roof Measurement
One reason why measuring a roof by satellite is so accurate is due to the fact that you have as high and clear a vantage point as is possible. You can zoom in as much as you want, depending on the tool used, and everything is easy to see and put together. In other words, there’s no way to get any higher or see the roof from any better of an angle than from far above in a satellite.
Roof Measurements from Satellite
Another thing that helps to enhance the accuracy of satellite roofing measurements is the combination of pairing the satellite photos with software to help get the best and most accurate measurements possible. By starting with such good photos, strong software designed for the purpose can help ensure accurate measurements of the roof.
That’s why it’s so important to make sure you use the right software. Its accuracy will depend on its capabilities. But, it will also depend on its inputs. IN other words, one of the reasons why the satellite approach is so accurate is because it has fantastic inputs from the satellite photos. Otherwise, this accuracy wouldn’t be where it is.

How to Get Accurate Aerial Roof Measurements?
- 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.
- Note any skylights, chimneys or other parts of the roof that would not require materials so you can subtract those measurements from your total area.
How do you measure a flat roof?
Rooftop Measurements
- Prepare roof measurements and professional estimates from anywhere.
- Print email and share digital reports with property owners or with your team.
- Eliminate unnecessary trips to the job site.
- Spend less time on roofs and more time with customers face-to-face.
- Impress clients with new roof simulations, roof diagrams and other visuals.
How to Measure Roof Slope from On the Roof
To use the direct roof slope measurement procedure, in addition to safe access to a roof that won’t be damaged by touching or walking on it, you need: a tape measure and a carpenter’s level. This procedure to measure roof slope can be performed on the roof or from a ladder at roof edge.
- Hold the carpenter’s level in a horizontal position with one end touching the roof surface.
- Measure out 12″ along the level bottom edge – the green line in our sketch. Mark this point on the leve.
- Measure straight down to the roof surface from the mark you just made – the blue line in our sketch.
- Read that distance in inches. The result is inches of rise per foot of run.
How to Manually Measure a Roof
- 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.
- Note any skylights, chimneys or other parts of the roof that would not require materials so you can subtract those measurements from your total area.
- Add together the calculated square footage of each surface to get the figure for total square footage of the roof.
- After determining the total square footage of the roof, you must calculate the pitch of the roof by measuring the vertical distance (rise) over a 12 inch horizontal segment (run).
- Write down these numbers as the vertical measurement listed first and the horizontal measurement recorded second so you can find rise over run.
- 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.
