How to calculate length of roof rafters and pitch of roof Civil Sir (2022)
1. Convert your roof pitch into inches similar to your horizontal measurement (e.g., 4:12 becomes 4/12 or 1/3). 2. Multiply that fraction by half of your horizontal span measurement. 3. Square this value and add it to half of your horizontal span's squared value. 4. Take the square root of this sum for your rafter length. For example:
There are a couple of different ways and methods you can use to calculate rafter lengths. Each
This online rafter calculator helps you calculate rafter length based on the roof slope ratio in inches per foot and the width of the building. The computation includes results for the hip/valley factor, slope factor, and the roof slope in degrees.
The Easiest Way to Calculate Irregular Hip Rafters
A roof rafter is a type of internal vertical beam that holds up a building's roof load, or weight from above, and constitutes a roof's framework. The Rafter length is determined by the pitch/angle of the roof, its span and the amount of overhand required for water clearance/gutter fitting. Roof Rafter Calculator. Overhang. feet inches. Roof Span.
Rafter Length Calculation Inspection Gallery InterNACHI®
You can use the following equations to find the length of the rafter and the slope: rafter² = rise² + run² (from the Pythagorean theorem); rise / run = pitch, where pitch is expressed in percent; and pitch = tan (angle), where angle is the roof pitch expressed in degrees.
How to calculate length of roof rafters and pitch of roof Civil Sir (2022)
Rafter Length = Square Root of (Run^2 + (Pitch/12)^2) Where: Rafter Length is the length of the rafter. Run is the horizontal distance from the roof's ridge to the outer wall (half of the building's width). Pitch is the slope of the roof, typically expressed as the rise in inches for every 12 inches of horizontal run.
