Minus ridge thickness to allow for ridge becoming pole plate roof peak will be slightly higher ridge thick must be same. 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.

Hip roof area calculator. A 12 in 12 pitch is a. A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally.

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. The most common hip roof pitch ratios fall between 4 12 and 6 12 although variations occur based on factors such as snow rain and wind conditions which is because steeper hip roof pitch ratios allow for less accumulations of snow and rain on the roof and lower ratios provide less wind resistance. Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs. Select the following information by using the drop downs to enter values in feet and inches.

All formulae are below the calculator. Modern residential hip roof construction uses common pitch ratios in general.

Enter the extension wall length into wall length and double the extension wall width then minus ridge thickness into the wall width entries.

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. The difference is in the amount of ridge capping you need and the amount you will waste.
