Like our Facebook Page*For a 10×12 shed roof, you need 6 bundles of shingles that’s about 174 pieces of three tab strip. That’s for a standard size asphalt shingle with overhang of 1 foot while assuming the roof pitch of 6/12. The cover area for a 10×12 shed roof is 2 squares and so you can estimate the bundles keeping this area in mind.*

But as I said, the calculation involve considering roof pitch, overhang, and other factors. So, I recommend you continue reading the entire article to accurately know how many bundles of shingle do I need for a 10×12 shed; let’s delve in:

## Calculating Quantity of Shingle for a roof

For a flat roof, estimating the quantity of shingle require is a pretty straight forward process. But as in most cases, you’re going to deal with the sloping roof, aka hip roof; the calculation is bit different. It’s not that you just know the area, divide that with area of one shingle and get the required quantity of shingle.

For a 10×12 roof, the footprint comes as 120 square foot; but if you take this area as that of the roof surface, you’re doing a big mistake. The roof shed area because of the slope is more than a flat area. If you still don’t want to go into all that pitch effect, I recommend you at least consider double area than only taking the flat square footage.

Here’s what you should know

## What is the term `Roofing Area` Means?

Traditionally the term **Roofing** includes the **Square**, ** a square is equivalent to 100 ft^{2}** or a 10 x 10 ft area. Accordingly a roof comprising of 2 squares contained an area of 200 ft

^{2}. The square footing of building is different as compared to square footing of roof due to slope or pitch of the roof and overhanging portion.

### Eave Overhang

The length of the **eave overhang** can vary from a few inches to a few feet and depending upon the requirements the length of eves overhang may vary from few (feet to inches). Normally the width of overhang portion is between 12 to 18 inches for eaves and not more than 8 inches for rakes.

## How do you calculate the square footage of 10×12 shed roof?

**Find the total area of the shed inclusive of overhang:**

To calculate the total area of the shed, including the overhangs,

You need to measure the length and width of your home to determine the extra length of overhangs. Assuming the overhang is 1 foot on each side, including eaves and rakes, add 2 feet to the total.

Therefore, for a shed with a roof size of 10×12, when factoring in the overhangs, the dimensions would be approximately 12 feet by 14 feet, resulting in a total square footage of 168.

**Find the Roof Pitch or Slope:**

Roof pitch, also called roof slope, describes the value of the pitch.

Rise and run is defined as the distances inches from the rise of roof and horizontal distance from the covering of roof respectively.

In this article we will consider the roof of the 6/12. This means that for every 6 inches the roof rises vertically and extends 12 inches horizontally.

In order to calculate the area of roof, the given below steps are required;

**Square the rise & run**

First, we **square the rise**, which in this case is 6 inches, resulting in 36. Next, we **square the run**, which is 12 inches, resulting in 144. By the **addition of two values**, a sum value of 180 is achieved.

**Take the square roof of the sum of the rise & run squares**

Approximately13.417 is obtained by the **square root** of 180 in finding the square root of this sum.

**Divide the sum by 12 and get the product factor**

This value is then divided by 12, resulting in 1.118. This calculation gives us the product.

**Increase the area of roof with this factor**

To determine the roof area, we **multiply the product (1.118) by the square footage of the shed**, including the overhangs, which is 168 square feet. The multiplication yields 188.064 square feet. Finally, we divide this result by 100 to convert it to squares. Thus, the **roof area is approximately 1.88 squares.**

**Don’t forget the wastages**

At the end, we need to add 10% for wastages. So, 10% of 1.88 will be 1.88 + 0.188 = 2.068 squares; so we can round it off to 2 squares.

## How many shingles do I need for a 10 x12 shed?

As a general guideline, it is common to require 3 bundles of shingles to cover an area of one square, equivalent to 100 square feet of roof surface. Each bundle typically contains 29 standard-sized shingles, specifically three-tab strip shingles, measuring 12 inches by 36 inches.

The objective of packing the shingles in bundle form is to ensure that these are being lightweight and easy for individuals to carry them .

For most types of roof shingles, including asphalt shingles, they are commonly sold in bundles. In the case of a roofing project involving a 10×12 shed roof, which has an average size of 2 squares, approximately 6 bundles of three-tab asphalt shingles or suitable starter strips would typically be required to cover the area.

To determine the number of shingles needed for a 10×12 shed roof, you would require approximately 2 squares or 6 bundles of three-tab strip standard-sized shingles (measuring 12 inches by 36 inches). Considering the overhangs of 1 foot and a roof slope of 6/12, this calculation amounts to a total of 174 individual shingles.

**Hence, to sufficiently cover the roof of size 10 x 12 shed, one may need 174 pieces equivalent to 6 bundles of shingles or roofing material of 2 squares.**

It is important to remember that while calculating the shingle numbers for 10 x 12 roof you will need 3 shingles for each roof square.

As a result, for a 2-square roof (10×12 shed), the total number of bundles needed would be 6. This estimate is based on using three-tab strip standard-sized shingles, measuring 12 inches by 36 inches, with overhangs of 1 foot and a roof slope of 6/12.

## Conclusions

The quantity of shingles required for a 10×12 shed roof varies depending on the specific type of roof. On average, for a 10×12 shed roof with overhangs of 1 foot and a roof slope of 6/12, you would typically need approximately 2 squares or 6 bundles of three-tab strip standard-sized shingles. This equates to approximately 274 individual shingles, each measuring 12 inches by 36 inches.
