Unequal pitch hip roof calculator.

The hip roof framing calculator returns the value of the main rafter the side rafter the length of the hip the height of the knee wall and the lengths of the jack rafters. For example in an equal hip roof with an 8 12 pitch the pitch of the hip rafter would be 8 17. There are lots of things to think about and consider when taking on a hip roof style so having a reliable all in one hip roof calculator is going to be very useful for this job. All formulae are below the calculator.

But here it will be different since the hip rafter doesn t lie at 45 degrees to the commons. Enter the extension wall length into wall length and double the extension wall width then minus ridge thickness into the wall width entries. The pitch of the unequal hip rafter can be expressed in relation to either the main roof or the secondary roof. It will display the framing square usage for the slope angle of the hip rafter 27 50055 6 12.

It is often compared to slope but is not exactly the same. Major side plan angle. How to use the hip roof framing calculator. After that you will have to try and find a good hip roof pitch calculator to make sure you can get the last of the calculations.

Roof pitch is the measurement of a roof s vertical rise divided by its horizontal run. Major side roof span building width ridge thickness 2. To get results you need to provide roof base dimensions length and width and roof pitch we assume it is identical for all sides. Although ceramic tile roofs are expensive they can have a life span of over 100 years.

Major side roof pitch major. Minor side roof pitch minor. Determining the slope and skew angles related to hip and valley beams can be a challenge made even more difficult when the roof slopes on each side if the hip or valley are different. This slope and skew calculator makes it easy by performing all of the necessary trigonometry for each hanger condition in the roof.

Porch roof extensions for hip roof porch extensions from an existing building wall you can use half the calculator results. One of users asked us to create calculator which will help him estimate hip roof parameters like rafter s lengths roof rise and roof area. Minus ridge thickness to allow for ridge becoming pole plate roof peak will be slightly higher ridge thick must be same. Slope and skew calculator.
