Roof Line Length Calculator

Slope the slope of a roof is represented as x 12 where x is the number of inches in rise for every 12 inches of run this is very useful information for many purposes especially for roof framing the slope sometimes called pitch is calibrated on speed squares.

Roof line length calculator.

Measure the rise of your roof. The rise of the rafter. Rafter is the beam supporting the building. A useful shed roof rafter calculator to calculate the rafter length for the given dimensions of the roof of the building or a structure.

Our roof rafter calculator tools are handy for calculating the number of rafters needed rafter length calculator lineal feet of rafter board feed in ridge and sub facia and the total board feet in the roof. Enter the value for the roof width outside to outside in feet inches and fraction inches and fraction or use the inches box to enter a value in decimals if that is your preference. Calculate the length of a rafter from the roof slope ratio of inches per foot and a building width measurement. Calculate the rafter length substituting these values into the following formula.

The roof pitch calculator is a convenient online tool you can use to quickly assess the pitch of your roof to determine the length of rafters you need. Measure the run length it is the horizontal distance between the roof ridge and the wall of the building. Find its length with our online rafter length calculator. The house base area is the area of land that the house covers and for more complex shapes can be estimated using the area calculator.

After finding out your roof pitch angles you can use the calculator to perform the calculations for you instead of doing them manually. It will give you a roof pitch angle and a ratio between rise and run in the form of x 12. Let s say it is equal to 1 5 m. If you add an eaves overhang dimension then the amount the rafter sticks passed the wall will be added to the rafter length.

Includes result for hip valley factor slope factor and the roof slope in degrees. Height of the scaffold. The length of the rafter. As you begin to calculate various costs you will see that the cost is a result of the interplay of many different variables including roof area in terms of footage measurement of any roof extras like chimneys or skylights and the dimensions of.

Let s assume it is equal to 6 m. Roof pitch calculator results explained. The run of the rafter. Rise and run means that a 6 12 pitch roof has 6 of rise vertical for each foot of run horizontal.

Roof slope calculator example of use. The following tools estimate the area of a roof as well as the amount of materials necessary to construct a roof of a given area.
