# Hip roof calculator

The following tools estimate the area of a roof, as well as the amount of materials necessary to construct a roof of a given area. The "House Base Area" is the area of land that the house covers, and for more complex shapes, can be estimated using the Area Calculator. The calculated area is only an estimation.

In cases where a roof has a complex shape, such as in the image to the right, measuring the dimensions and areas of each part of the roof to calculate total area will result in a more accurate measurement of area. The calculator cannot account for complex shapes based on a measurement of square footage alone. The Area Calculator can be used to calculate the area of a variety of simple shapes that together can comprise the area of the roof.

Using the aggregate area of these simple shapes can yield a more accurate roof area to be used with the Roofing Material Calculator. The most common roofing materials used in the United States include shingles, membrane roofing, and ceramic tile, all of which have different life spans. Shingle roofs typically have a life span of years, while membrane roofs usually last years. Although ceramic tile roofs are expensive, they can have a life span of over years.

Roof pitch is the measurement of a roof's vertical rise divided by its horizontal run. It is often compared to slope, but is not exactly the same.

In the United States, a run of 12 inches 1 foot is used, and pitch is measured as the rise of the roof over 12 inches. Outside of the U.

Roof pitch is a determining factor for cost of the roof, as well as the roof area, and the type of materials used.

It affects walkability as well as drainage, and roofs in areas of high rain or snowfall tend to have steeper pitches. Roof pitch affects the actual area of the roof. Depending whether the roof area is measured horizontally possibly from a drawing or photographa correction factor is necessary to determine the actual area of the roof.

Given pitch and a horizontal area measurement, multiply the horizontal area by a correction factor corresponding to pitch, provided in the table below, to determine the actual area of the roof to be used in the Roofing Material Calculator.

### Calculate the surface area of your roof

While it is possible to estimate the amount of necessary materials using only the total roof area measurement, as can be seen from the table, depending how large the pitch of the roof, the actual area of the roof can differ by up to 2.

As such, while it can be cumbersome, measuring the area and pitch of each part of the roof and multiplying by the corresponding correction factor will result in the most accurate estimate of necessary roofing materials.

We will get through this together. Updated: June 18, References. Any roof which has 4 sides, all of which slope upwards to meet at a seam at the top of the roof, is a hip roof.

It is perhaps one of the simplest styles of roofing, and is often combined with gables or other features. While it's common to build hip roofs from trusses or premade frames, it is possible to build your own hip roof.

Begin by measuring and cutting the wood, then move on to installing the rafters and sheathing. To build a hip roof, start by measuring the width and height of the building you're putting the roof on. Then, enter those measurements into an online roofing calculator to determine how long each common rafter will need to be. Next, once you know the lengths of the rafters, cut some wooden planks to size and make birdsmouth cuts in each one so the rafters are able to connect to the tops of the walls.

Once you've done that, assemble the rafters and nail them into place to make the frame of the roof.

A regular hip has equal slopes on all sides while an irregular hip has different slopes on the main roof and hip end roof. Easy Rafters does not calculate a complete four sided hip roof, but rather calculates the common, hip, and jack rafters for one end of a hip roof.

To Calculate a Hip Roof Select Hip from the Roof Type dropdown list or click on the corresponding button on the toolbar to calculate a hip roof. The preview window displays a dimensioned plan view of the hip roof.

Main Slope Enter or select the slope of the main roof common rafter. The slope of the hip end will update automatically to match the main roof slope.

Hip End Slope To calculate an irregular hip enter or select the hip end slope after the main slope has been entered. Building Width Enter the total width of the building. Main Overhang Enter the horizontal overhang of the main roof common rafter including the fascia board. End Overhang This field is disabled for regualr hip roofs since the overhangs will always be equal. For irregular roofs select "Equal" or "Not Equal" from the dropdown list. Irregular hips will have unequal overhangs by default since the common and king common rafters have different slopes.

Making the overhangs equal involves offsetting the hip rafter along the main or hip end wall plate and adjusting the height of the hip end wall to compensate for the overhang difference.

Hip rafters must be dropped or backed so that the edges of the rafter won't interfere with the roof sheathing. Dropping a hip lowers the heel of the hip rafters while backing a hip involves beveling the top edges of the hip rafters. Dropped hips for irregular hip roofs will be shifted slightly off their centerline to compensate for the different amount of drop required for the main and hip end roofs.

Backed hips for irregular hip roofs will have different backing angles for the main side and hip end side of the hip rafter. Note: The hip shift or backing angles will be displayed in the hip rafter top view on the Hip tab and in the deatil drawing on the Corner Detail tab.

Rafter Spacing Select an on center spacing from the dropdown list. The spacing is used to layout the jack rafters on the Layout tab. Note: the spacing can also be changed on the Layout tab.

The key is to be as accurate as possible since falling short, or an overage could mean thousands of dollars when planning your roofing budget. Below, there is a simple triangle, and the math used to work out how to make a proper measurement. Once you work through the basic triangle, we will review a typical roof, and how to apply some simple math to calculate how much material you will need for a roof used in our hypothetical example.

So if you divide your answer of a product of length times height by two, you will get the area of a triangle. Calculating an area of a triangle when estimating a roof. In this overhead view you see both a hip-end section, and gable ends. With a more complex roof such is this one, it is highly recommended that you make a basic sketch.

By doing so, it will be easier to mark your measurements, and calculate your materials. For this example we will break this roof up into sections labeled A through E. A sketch of a Hip and Gable Roof. Calculating for a Basic Triangle of a Hip Roof. In the figure B. As we did in the first example, measure the length of the eaves, and the vertical line from the eaves half way point to the peak.

Multiply these numbers, and then divide the answer by two. The easiest way to measure this section is to divide it up into three different sections: S1, S2, and S3. As you can see, S1 and S3 are the same size, but you still need to document all measurement points to verify your material calculation accuracy. Since S2 is now a rectangle, simple L x W is all that is required. An Overhead view of a Hip and Gable Roof split in sections.
