10 12 roof pitch rafter length.

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. The most common roof pitch is designed with a pitch ranging from 4 12 to 9 12. 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. Just enter the dimensions of the roof rise and run to get started.

Calculate the length of a rafter from the roof slope ratio of inches per foot and a building width measurement. With this set of specs we are looking at a rafter length of 5 3. 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.

Angle the angle of a roof is the same as the roof s slope except instead of being. This calculator is to be used as an estimating tool only. Rafter length using pitch v r 2 sqrt 1 p 2 where v overhang r roof span p pitch use our online rafter length calculator to quickly compute the length of the shed roof rafter by entering the measurements of overhead length of roof span pitch or angle. Roof base length width how roof pitch is calculated.

Roof pitch calculator results explained. Calculate the length of common rafters with this free and easy online tool by entering a dimension for the roof width selecting a pitch for the roof and the thickness of the ridge. The length of the rafter. A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally.

More they usually claim that 4 12 is the lowest you can go without any special underlayment. Area span on the flat please enter area span on the flat in foot. It varies depending on culture climate style and available materials. Height of the scaffold.

Calculate the length of your rafters. Input the rafter span on the flat eave overhang and pitch of the roof. We ll be building a 4 12 pitch roof with an 8 span with 1 of overhang. Includes result for hip valley factor slope factor and the roof slope in degrees.

Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12. The rise of the rafter. Our roof we will be constructing will be 4 12. If you add an eaves overhang dimension then the amount the rafter sticks passed the wall will be added to the rafter length.

To accurately calculate the area of your roof you must first determine its slope or pitch. There is no standard universal pitch of roof.
