Pitch Table Roof Rafters

The image below shows a cross section of our simple 12 x 13 house from the joist span tables section of this tutorial.

Pitch table roof rafters.

Rise and run means that a 6 12 pitch roof has 6 of rise vertical for each foot of run horizontal. Roof pitches are given in rise in run rise over run and in degrees. 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. Angle the angle of a roof is the same as the roof s slope except instead of being.

Here we have a wood framed gable roof. Let s consider a basic gable wood roof framing design. The table will provide full scale the full scale number will be the length of the rafter in inches for each foot of horizontal run distance. Continuing on from part 3.

Roof pitch calculator results explained. Visit the roof framing page for more information on cutting roof rafters and visit the roof pitch calculator for determining rafter lengths based on rise and run. This table shows the roof pitch multiplier also called the roof pitch factor for typical roof slopes used to find the area of sloped roofs or the lengths of common rafters. The rafter tables allow you to calculate the length of a rafter by choosing a full scale number that matches the unit rise slope or angle of the roof.
