Shingle Coverage and Calculation
Architectural shingle bundles vary from 20 – 23 shingles per bundle. The company states it takes 64 shingles to cover 100 square feet of the finished roof. Since 64 doesn’t divide by three, some packages will contain 21 and some will contain 22.
Most shingles require only 3 bundles per 100 square feet to cover an area. If you have a roof area of 3000 square feet, you’ll need 90 bundles of shingles. You may also ask, how many bundles of shingles do I need for a 12×12 roof?
For traditional 3-tab roof shingles, there are 26 pieces in a bundle. Architectural shingles have around 21 shingles per bundle for similar coverage, as they are larger. Depending on manufacturer, the number in a bundle varies widely.
Shingle Bundle Size and Cost
A bundle typically covers 33 square feet regardless of shingle type. You must account for waste from cutting and overlapping. Divide total square footage by 33 to calculate bundles needed.
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.

Shingle Material and Pricing
Many roofing companies will charge between $3.50 and $5.00 per square foot. Asphalt shingles and most other roof shingles are typically available in bundles. For each roofing square or 100 sq ft, you’ll need three bundles of shingles. The average size of a roof is 30 squares, which typically requires 90 bundles of three-tab shingles or any other starter strips.
Quantity Calculation and Industry Standards
GAF and Owens Corning architectural shingles require 3 bundles per square. So for 100 square feet you need 3 bundles.
To calculate squares, measure the length and width of each section of roof then multiply to get the area in square feet. Divide by 100 to get the number of squares. Then multiply squares by 3 to get bundles.
Additional Information
A bundle weighs 75-100 pounds. Prices range from $25-75 per bundle depending on quality. Delivery costs extra since it’s heavy.
Only asphalt shingles are sold by the bundle. Other roofing materials like wood, metal or slate use different packaging.
