How much space up sink on angles roof.
Using the example values of a roof area of 210 square feet and an effective sheet size of 18 75 square feet 12 sheets are required as 210 divided by 18 75 equals 11 2.
This means that the rise of the slope goes up or down 8 inches for every 12 inches.
It is a traditional roof shape employed everywhere from tropical.
You ll need to figure out the vertical distance also known as the rise over a 12 horizontal segment also known as the run.
The slope of a roof or pitch is determined by how many inches the roof rises over 1 foot or 12 inches.
For example the arc tangent of 0 5 is 26 57 so the roof angle or angle of the slope is 26 57 degrees.
An example for a steep sloped roof is 8 12.
The next step is to measure the pitch also referred to as the roof slope of the roof deck.
Record these values as roof rise over run with the vertical measurement listed first and the horizontal second.
To put it in perspective the angle of this slope would be around 30 degrees.
If you re thinking about replacing your roof with a new one you will need a roof truss calculator.
