The online roof rafter calculator is designed for quick and convenient calculation of the key parameters of the rafter system. With this tool, you can accurately determine the rafter length, roof pitch, and rafter cross-section, which is essential for ensuring the strength and durability of the structure.
Main features of the calculator:
- Calculation of roof geometry, including the span width and overhang length.
- Option to calculate based on either roof pitch or post height.
- Consideration of snow and wind loads, selection of the construction region, and terrain type.
- Determination of roofing material type and rafter spacing.
- Calculation of rafter dimensions based on timber grade and other parameters.
How the calculator works:
- Step 1: Roof Geometry. Enter half the span width and the overhang length, then select whether to calculate based on roof pitch or post height.
- Step 2: Loads. Specify the snow and wind region, terrain type, and select the roofing material.
- Step 3: Cross-Section. Input the timber parameters and determine the rafter cross-section based on the load.
- Step 4: Results. After entering all the data, click "Calculate" to get a table with the calculated values.
This rafter calculator helps prevent design errors by providing accurate data for selecting materials and their dimensions. It takes into account factors such as snow and wind loads, as well as the specific characteristics of the roof structure, allowing for precise rafter strength calculations.
