How many square feet does one square of 235 lb shingles cover?

One square of 235 lb shingles covers 100 square feet. This standard measurement for roofing materials, including shingles, is crucial for planning and estimating the amount of material needed for a roofing project. Knowing that one square equals 100 square feet allows contractors to accurately calculate the total area of the roof and determine how many squares of shingles will be required based on that area.

In the context of roofing, a "square" is a unit of area that simplifies measurements and is commonly used in the construction industry. Therefore, understanding this standard helps contractors in budgeting, ordering materials, and ensuring they meet coverage requirements without excess waste. This knowledge is integral to successful project execution and client satisfaction, as accurate measurements directly affect both cost and material efficiency.
