How Do You Figure How Many Shingles For A Roof

So if you have 24 squares multiply that by 3 to get 72 bundles.

How do you figure how many shingles for a roof.

For instance a 7 12 roof pitch means that the roof rises 7 inches for every 12 horizontal inches. Since transportation is a major cost factor expect prices to vary by location. Place the end hook of the tape on the corner and run it all the way to the opposite corner of the house. 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.

Get the square footage of roof and divide it by 100 and it will give the number of squares you need and for every decimal number over 3 buy a bundle to achieve the amount of material. To estimate roofing materials start by finding the total square footage of the roof and divide the number by 100 to determine the number of squares in the roof. Since it takes 3 bundles of shingles to cover a square plan to purchase 3 bundles for each square. When figuring the amount of shingles needed to roof a house you first convert the total square footage of the roof to squares a square represents 100 square feet of area covered by shingles.

The average bundle of shingles covers 33 3 ft 2 so three bundles of shingles are needed per square. However if you are using heavier shingles you will require 4 to 5 bundles for a square. A square of shingles would be a minimum of three bundles. Asphalt shingles range in price from about 25 per bundle for a standard 3 tab style to around 50 75 or more for an upgraded architectural style.

The number of squares determines the amount of shingles needed. When you are using 3 bundles for a square you will be getting 29 standard shingles in each bundle. As a rule of thumb there are 3 bundles to a square assuming that you are using three tab strip shingles. However shingles are packaged in a way that they are light enough for the average person to carry around.

It is common to use 3 bundles to a square of shingles. Measure both the width gable side and the length eave gutter side. To figure out how many bundles you ll need multiply the number of squares by 3. Asphalt shingles are sold in bundles that can cover 1 3 of a roof square or roughly 33 square feet.

A square of shingles is the number of shingles needed to cover 100 sq feet of roof area. A square of roof is approximately 100 square feet of space on top of your home whether it runs at a slant horizontal to the yard or vertically toward a chimney or gable. Shingles typically come in a bundle that s large enough to cover 1 3 of a square. Singles are often sold in bundles with three bundles equaling one roof square.

Then add 10 to the number to account for waste. Determine the number of shingle bundles you ll need by multiplying by 3.
