How many bundles of shingles do I need for a 12x12 roof?

How much will one bundle shingles cover?

You usually purchase shingles by the bundle. Standard shingles are 12 by 36 inches and come 29 to a package. Most shingles come 3 bundles to a square — which is equal to 100 square feet. So, each bundle provides about 33 square feet of coverage.2021-02-23

How many packs of shingles do I need?

Laminate or architectural shingles, one of the most common types of roofing shingles, are generally packaged in three bundles per square. So in the 2400 square foot gable roof example, you would need 72 bundles of shingles (24 squares x 3 bundles per square = 72 bundles).

How do you calculate shingles for a shed roof?

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.
