How Many Shingles Do You Need for a 1884 Sq Ft Roof : Calculating Shingle Quantity for Your Roofing Project

Calculating the number of shingles you need for a 1,884 square foot roof starts with understanding that shingles are sold by the "square." One roofing square equals 100 square feet. To determine what you'll need, divide your total roof area by 100: 1,884 ÷ 100 = 18.84 squares. Since you'll always want to round up for waste (typically 10% extra is advised for cutting and odd angles), you should plan for around 21 squares of shingles. Most standard shingle bundles cover 1/3 of a square, so you'll need roughly 63 bundles (21 x 3) to complete the job. Keep in mind, roof pitch and complexity can increase waste, especially if your design includes dormers, valleys, or multiple roof sections.

Tips 1:

As a designer, I recommend creating a detailed drawing or using a 3D floor planner to accurately visualize your roof’s dimensions and unique features. This approach can help minimize material waste and provide a clearer estimation, especially if your project includes complex architectural elements.
