After stepping off the length and width of your home, youll multiply the two numbers to get your homes footprint.

**Length x width = your home’s footprint**

## How Many Shingles Do I Need For A 2424 Garage

For this example, well use the same type of roof a simple gabled roof. For our purposes, well say that the roof extends 1.5 around each side.

Well first calculate one face of the roof. The length of the roof is 24+1.5+1.5, which equals 27. The roof pitch is 4:12, which means the width of the roof is about 12.5. Add 1.5 of overhang to this number and you get 14 of roof width on one roof face.

Multiply 27 by 14 and you get 378 square feet for one roof face. The total roof area is 756 square feet. Divide this number by 100 to determine the amount of roof squares youll need, which equals 7.56 roofing squares.

Multiply 7.56 roofing squares by 3 bundles per square. Thus, 23 bundles of shingles are required to cover a 24×24 garage with 1.5 overhangs on all sides.

## How Do You Calculate The Roof Square Footage Of 1500 Square Feet House

**Figure out the area of the house plus overhangs**:- determine the squre footage of the shed foot print by measuring the length and width of the shed including the overhangs. Assume the overhangs are 1 feet both sides eves and rake then you have 2 feet extra, so each dimension for 30×50 = 1500 sq ft with overhangs is around 32×52 = 1664 square footage.

**Find the roof pitch or slope**:- the roof pitch is the amount of slope. The slope is described by the rise in inches or how far up it goes over the run in inches or how far horizontal it goes. We will use a 4 in 12 pitch. For every 4 inches the roof goes up to the peak it goes 12 inches horizontally.

**Calculate the square of rise and run and sum it**:- square of rise 4×4=16, square of run = 12×12 = 144, add both 16 +144 = 160.

**Find the square root of the sum**:- square root of 160 = 12.649

**Sum divide by 12 to get the product**:- square root of 160 = 12.649 is divided by 12 as 12.649 ÷ 12 = 1.054, hence 1.054 equals the product

**Multiply the product by the flat roof area and divide by 100**:- our house is 1500 square footage which as 1664 sq ft with overhangs, so 1.054 x 1664 = 1754 square feet, 1454 / 100 = 17.54 squares.

**Add 10% for wastes and starter**:- wastages 10% of 17.54 squares = 1.754, so final squares of shingles do you need = 17.54+ 1.754 = 19.294 squares, it is rounded to 19 squares.

## How Many Bundles Of Shingles Do I Need For 2100 Square Feet

## How To Account For Shingle Wastage

There will always be a certain amount of wastage when constructing a shingle roof, but this can vary hugely depending on the shape of your roof and any extra features it has.

For a complex roof with lots of corners, you can expect to go through more wastage and offcuts of shingles compared with a simple roof. Roofs with dormer windows or skylights will also have more wastage compared with those that dont, as you will need to make more cuts in the shingles, and the leftover portions will be unusable.

For any roofing project, you should buy between 10 and 15 percent more shingles than you have calculated. So for a roof that measures 20 squares, you should buy an additional 2 or 3 squares to account for wastage. This is because 10 percent of 20 is 2, and 15 percent of 20 is 3. If you are ordering your supplies in bundles, then this will mean you will want between 6 and 9 extra bundles, based on the fact that there are 3 bundles in each square.

Although this might seem like needless extra expenditure, you dont want your project to be delayed if you run out of shingles and cannot get hold of more of the same ones immediately. It is always safer to have more shingles than you need as opposed to less.

If you have shingles left over at the end of your project, you should save them for future repairs or replacements on your roof, so you wont have to have mismatching shingles.

## Why Is It Important

A roofing square is an important measurement for roofers. It is the most common way to measure a roofs size. Roofers use this measurement to calculate the amount of material they will need to cover a roof. This measurement is also used to price a new roof. A roofing square is equal to 100 square feet.

Roofers will measure the length and width of a roof and divide it by 100. This will give them the roofs square footage. Most roofs are not perfect squares, therefore this measurement may be difficult to calculate without a roofing square ruler or tool such as a credit card that is 100-square inches long.
