How many bundles of shingles do i need for 100 square feet

Thus, it will take 4 bundles of 3-tab standard size shingles (12″×36″) to cover 120 square feet roof. Thus, there are 4 bundles of standard size 3-tab shingles you will need to cover 120 square feet roof.

This makes it relatively easy to figure out how many shingle bundles your roof requires: simply multiply the number of roofing squares by three. If your roof's area were equivalent to about 20 roofing squares, then you would need about 60 bundles of shingles.

A bundle typically covers 33 square feet regardless of type of shingles you have. So even though, say, you get fewer architectural shingles in a bundle than a standard shingle, those architectural shingles cover a larger area, so the square footage is about the same.

Roof surfaces are measured in “squares”. A roofing square is equal to 100 square feet of the roof. To determine the number of squares on the gable roof example in this post, divide its total of 2400 square feet by 100 (2400 ÷ 100 = 24). This means you would need 24 squares of shingles to cover that roof.
