How to calculate hip roof pitch.

To get results you need to provide roof base dimensions length and width and roof pitch we assume it is identical for all sides. Roof slope calculator example of use measure the run length it is the horizontal distance between the roof ridge and the wall of the building. Hip roof is a roof with a sharp edge or edges from the ridge to the eaves where the two sides meet. 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.

If you want to find the roof pitch in the form of x 12 simply calculate the pitch and substitute 12 for the run length. Enter the extension wall length into wall length and double the extension wall width then minus ridge thickness into the wall width entries. For any roof slope expressed as x in 12 rise in run the hip and valley factor is determined by finding the square root of rise run 2. All formulae are below the calculator.

Calculate the square footage area of a hip roof. The difference is in the amount of ridge capping you need and the amount you will waste. Calculate the amount of asphalt or fiberglass shingles needed to cover a hip roof. The only difference in this calculation to the one for a gable roof area is the amount of the ridge.
