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.
Hot to determin hip roof pitch.
If you re putting down new roofing materials on your home or another building with a hip roof your first step will be to find the exact dimensions of each of the roof s individual faces then use those measurements to calculate its total area in square feet.
Hip roof is a roof with a sharp edge or edges from the ridge to the eaves where the two sides meet.
Here is the online hip roof area calculator which helps you calculate the hip roof parameters such as roof rise common and hip rafters length and roof area based on width height of roof base and the roof pitch identical for all sides.
Enter the extension wall length into wall length and double the extension wall width then minus ridge thickness into the wall width entries.
To get results you need to provide roof base dimensions length and width and roof pitch we assume it is identical for all sides.
Hip roof area 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.
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.
Minus ridge thickness to allow for ridge becoming pole plate roof peak will be slightly higher ridge thick must be same.
On a related note the pitch properly the slope of a hip or valley rafter will not be the same as the pitch of the adjacent roof sections.
All formulae are below the calculator.
A hip roof s square footage is equal to that of a gable roof with the same dimensions.
The top ridge will be shorter for a hip roof but the 4 hips will add to the amount of ridge capping needed and because of the angles the amount of waste will be higher.
Modern residential hip roof construction uses common pitch ratios in general.
Select the following information by using the drop downs to enter values in feet and inches.
Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs.
The difference is in the amount of ridge capping you need and the amount you will waste.
A 12 in 12 pitch is a.
A hip roof is a common roof style characterized by 2 pairs of opposing faces sloping downward from a high peak.
While the slope of the common rafters are expressed as x in 12 the slope of the hip and valley rafter on the same roof will be x in 16 97 so where two roof sections intersect to form a 90 angle a regular hip or valley and each roof.
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.
To accurately calculate the area of your roof you must first determine its slope or pitch.
