How do satellite roof measurements determine pitch.
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.
The first thing you need to do is download and install google earth pro.
The next step is to measure the pitch also referred to as the roof slope of the roof deck.
Time is money and if you choose to use satellite image measurement tools those costs can add up.
Zoom in on the roof then select tools at the top left then select ruler.
A 12 in 12 pitch is a steep 45 degree angle roof.
Here s an easy safe way to determine the pitch from inside your attic.
A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally.
You ll need to figure out the vertical distance also known as the rise over a 12 horizontal segment also known as the run.
For instance a 7 12 roof pitch means that the roof rises 7 inches for every 12 horizontal inches.
Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs.
Record these values as roof rise over run with the vertical measurement listed first and the horizontal second.
It s pretty self explanatory after that.
See the image below for more explanation on rise run and pitch.
If the angle changes too much when you zoom in go to view at the top left then click on reset at the bottom of the drop down menu then click tilt.
Often you express roof pitch as the ratio between the rise and the run in the form of x 12.
For help determining the area of a sloped roof see here.
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.
You can assess this in two ways either as the roof pitch angles which the rafters make with the horizontal or the proportion between the run and the rise of the roof.

Roof pitch refers to the slope which the rafter creates.
