100 sq. feet

200 sq. feet
250 sq. feet

The correct answer is: 100 sq. feet

One square of asphalt shingles covers 100 square feet of roof area. This standard measurement is essential for contractors and builders when estimating the amount of roofing material required for a project. Understanding this standardization helps in accurate budgeting and ordering of materials, ensuring that the project proceeds smoothly without delays caused by material shortages. In roofing terminology, a "square" refers to an area of 10 feet by 10 feet, allowing contractors to easily calculate coverage based on the dimensions of the roof. Accurate knowledge of this measurement assists in making informed decisions on how many squares of shingles to purchase for a roofing job, which is vital for expense management and project planning in construction.
