Reliable roof measurements make projects go smoothly and stay on budget. Whether you’re a contractor training a new employee or a homeowner budgeting for a new roof, use this guide to accurately measure and calculate roof squares for any roof.
First, you’ll need to determine the roof’s total square footage
A steeper roof needs more materials. Pitch measures roof steepness, boosting measurement accuracy.
A roof square is a 10 x 10 area equal to 100 square feet of roof surface. To calculate:

The purpose of calculating the precise measurements of a roof is to ensure you order the appropriate amount of roofing materials – whether it’s for a shingle, metal, and any other type of roof. Here are common roofing materials and considerations.
Shingles are sold in bundles. Depending on type and brand, it may take a different number of bundles to make a roof square. When comparing shingle cost, remember to base price on squares and not on bundles.
Metal roofing is great for homes in snowy regions. It’s typically sold by the sheet or panel. To determine the number of sheets or panels neeeded to cover the roof, divide the width of the roof by the sheet or panel width.
The basic roof square calculations detailed above will help estimate cost for other materials. Be sure to include the cost of leak barriers, deck protection, drip edge, rake edge, ridge vents, hip and ridge caps, etc.
