How to figure shingles for a gambrel roof. A gambrel or barn style roof is simply a gable roof with a change in slope partway up the roof. To calculate a gambrel roof select gambrel roof from the roof type dropdown list or click on the appropriate toolbar button to calculate a. Besides its unique appearance a gambrel roof also serves to maximize the usable floor space in the attic area. Inches enter the overhang of the gable.

Move slider or directly enter angle to alter sweep angle of lower rafters and change the shape. Shingle roofs typically have a life span of 15 30 years while membrane roofs usually last 5 15 years. Roof pitch is the measurement of a roof s vertical rise divided by its horizontal run. If the existing shingles are standard 3 tab shingles you can get this measurement by taking note of the number of tabs along the eaves and ridges then determine the length in feet.

You should utilize three tab asphalt shingles for this project. Although ceramic tile roofs are expensive they can have a life span of over 100 years. The application of shingles over a gambrel roof has very little variation from the application of shingles to a traditional roof. Feet inches enter the overhang of the eaves.

For example you will need to figure out the exact number of shingles required to cover the entire roof area. Determine the total number of squares. To do this you need to note that one tab will be equal to 1 foot. A gambrel roof is often thought of as a bard style roof where the roof of a structure has multiple slope changes on either side of the roof.

It is often compared to slope but is not exactly the same. Once you know this number you can estimate the final price of the materials. Divide the total footage by 100 to determine the number of squares in the. Inches enter the wall to upper pitch start.

The length measured from the outside of the wall to where the upper. Determine the bundles of shingles. Measure the length and width of each portion of the roof multiply length by. Depending on the size of the roof and the pitch of the roof these angles will change.

Check overhang to calculate rafter overhang equal to the lower level cut at the full rafter depth. To calculate the size of the roof you need to measure the size of the roof as if it were flat account for roof pitch calculate square footage and finally determine how many squares of material are required for the roof the calculator above can handle all of this simply enter the length width and pitch and it will determine the size of the roof in squares. Gambrel roof framing geometry calculator inch this gambrel roof fits in a semicircle and starts as the top half of an equal sided octagon. Thus a key element in your project will be the roofing material calculator and more specifically the roof shingle calculator.

Find the square footage of the roof. You will then have to get the measurement of the rake of the roof.
