2.2 Safe to install
This roof and rafter calculation application offers a comprehensive toolset for both professionals and DIY enthusiasts. It streamlines the process of determining rafter and hip/valley lengths necessary for constructing complex multi-projection roofs or a simple backyard pergola. The app also facilitates the calculation of plumb and foot cut angles, featuring a practical bevel guide for precise transfer of angles. Additionally, it can be used to estimate roof areas by multiplying rafter length by the building's length or span.
To utilize the application, users should select their preferred measurement system—imperial or metric—before entering the relevant data. Input parameters include the roof pitch, half-span or half-width of the structure, and rafter spacing. The app then calculates essential dimensions such as:
- Rafter length
- Hip and valley length
- Hip/valley creeper rafter shortenings
- Roof rise per linear meter or per 6-foot span
The interface displays detailed cut information for hips, rafters, jack rafters, and foot cuts. These measurements can be transferred using several methods:
- Directly scribing from the smartphone screen onto roofing materials
- Adjusting a miter saw to the displayed angle shown on the screen
- Setting a bevel from the on-screen image
- Positioning the phone on your miter saw to match the displayed angle for quick setup
