How to figure shingles for a gable roof.

Feet inches enter the overhang of the eaves. Measure the length and width of each portion of the roof multiply length by width for each plane and then add the planes together for the total square footage. For example you will need to figure out the exact number of shingles required to cover the entire roof area. The pitch of the roof is the rise over a 12 inch run.

Pitch measurement method 1. A hip roof s square footage is equal to that of a gable roof with the same dimensions. Calculate the amount of asphalt or fiberglass shingles needed to cover a hip roof. Thus a key element in your project will be the roofing material calculator and more specifically the roof shingle calculator.

Use our roof pitch calculator to find the pitch of your roof. Measure your roof accurately use a measuring tape preferably 50 or 100 feet long and get exact ground dimensions of your house. If you have a simple gable roof you ll only need to measure and sum up the 2 planes of the roof. Find the square footage of the roof.

On a ladder beside the roof place the level a foot or so up the roof hold it level and measure from the 12 inch mark on the level s bottom straight down to the roof. Feet inches enter the width of the building. Hold the end you measured from against the bottom of a rafter so it s sticking straight out horizontally and is level. For example a 4 12 pitch roof that is 100 square feet.

From the 1 ft 0 30 m spot you marked on the level measure upward to the rafter. 100 1 054 105 4ft 2. Once you know this number you can estimate the final price of the materials. Place the end hook of the tape on the corner and run it all the way to the opposite corner of the house.

Enter the length of the building. Measure the pitch of your roof in the attic. To do this you need to note that one tab will be equal to 1 foot. Mark a length of 1 foot 0 30 m on a long level starting from one end.

Inches enter the pitch of the roof. 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. Next multiply the footprint of the roof by the multiplier below for your roof pitch to find the overall roof area. You will then have to get the measurement of the rake of the roof.

The difference is in the amount of ridge capping you need and the amount you will waste. Roof pitch area multipliers. Rise 12 enter the square foot one pack will cover.
