I'd like to give everyone a bit of a heads up on the new version of the Roof Framing Calculator. It will have some improvements over the current version and there will also be a downloadable version that you can run right from your own desktop. They should roll out within the next 30-60 days. So stay tuned for the online update and the new Java based program.
The newest release of V3.0 brings improvements on how the calculator actually calculates the overhangs and the total lengths for the common, hip and valley rafters. It now makes provisions for sub fascia and fascia thicknesses as well as any building finishes that will be applied. These measurements are now factored into the overhang and final rafter lengths.
You can now explicitly set the calculations for either a hip or gable roof. All displayed measurements are now in feet & inches (06/29/2008).
Last but not least the ability to choose between single and double cheek cut hips has been implement. What's up next is the ability to calculate octagons roofs as well.
