Question: how many square feet are in one square of roofing?
Answer: 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 24,000 square feet by 100 (24,000 ÷ 100 = 240). This means you would need 240 squares of shingles to cover that roof.
