How many bundles of shingles do i need for 1000 square feet roof? The number of bundles of shingles you’ll need for a 1000 square feet roof depends on the type and brand of shingles you plan to use, as well as the slope and design of your roof. On average, a bundle of asphalt shingles typically covers around 33.3 square feet. To estimate how many bundles you need, you can divide the total square footage of your roof (1000 square feet) by the coverage per bundle (33.3 square feet per bundle):

1000 square feet / 33.3 square feet per bundle = approximately 30 bundles. So, you would need approximately 30 bundles of shingles for a 1000 square feet roof, but it’s a good idea to buy a bit extra for any potential waste or repairs

Calculation of shingles quantity is simple and easy if your house roof is flat, but majority of house in US have pitch roof that makes calculation of square footage area for pitch roof difficult. The house footprint is 1000 sq ft but the roof surface is quite a bit more due to slope. Gambrel roofs have different slopes and configuration pitch but generally the roof surface is roughly twice the footprint in square footage.

This article describes the basic maths calculation to calculate roof materials such as shingles. If you have ever question yourself “how many squares footage or square is my house roof?” this article will help you find the square footage of your roof. This article describe about the maths formula to figure out how much shingles you need to order.

When you talked Roofing is about using the term “square”, a “square” equal to 100 square feet of roof or a 10 foot by 10 foot area. So a roof that has 200 square feet of area has 2 squares. Remember that unless the roof is flat, the square footage of the building is different than the square footage of the roof because of the slope or pitch of the roof and the overhangs.

Eves overhangs can vary from a few inches to a few feet depending on requirements; however, it is suggested width of an overhang is between 12” and 18” for eaves and no more than 8” for rakes. That said, overhangs can extend as far as 2′ without the need for external supports.

As a rule of thumb, there are 3 bundles of 3-tab shingles required to a square or 100 sq ft of roof surface area. There are also 29 standard-sized shingles (three-tab strip shingles) measuring 12 inches by 36 inches in each bundle. A square of shingles is the number of shingles needed to cover 100 sq feet of roof area. However, shingles are packaged in a way that they are light enough for the average person to carry around. When shingles come three bundles to the square, there are 29 standard-sized shingles (12 in. by 36 in.) in each bundle.

Asphalt shingles and most other roof shingles are typically available in bundles. For each roofing square or 100 sq ft, you will need three bundles of shingles. The average size of house roof is 10 squares, which typically requires 30 bundles of three-tab asphalt shingles or any other starter strips.

Standard 3 tab shingles its 3 bundles to a square and architectural shingles its 4 bundles to a square on most. A square is 10′ x 10′ or 100 sq. ft. So if its a 1000 sq. ft roof you need 30 bundles plus 10% of ridge, starter and wastages which can be done with shingles or they make ridge caps and starters. If its architectural shingles it would take 40 bundles plus 10% of starter, ridge cap and wastages. With architectural shingles you have to use starter shingles and ridge caps you can’t really use the shingles for that.

**How many bundles of shingles do i need for 1000 square feet roof**

How do i calculate how many shingles I Need?, Once you’ve determined the square footage you need to cover, you can figure out the number of bundles you need by dividing the total square footage by **33**. For example: if you have **2,000 square feet** of roof to cover, that means you’d need about **60 bundles** (2,000 divided by 33 is about 60) of 3- tab asphalt shingles or 80 bundles of architectural shingles.

How many bundles of shingles do i need for 1000 square feet roof?, You will need approximately 30 bundles of standard size 3-tab asphalt shingles (10×3 = 30 bundles) or 40 bundles of architectural shingles (10×4 = 40 bundles) for 1000 square feet roof.

The number of bundles or squares you need will depend on the surface area of your roof, and its pitch or slope.
