Roofing Measurement and Material Guides
Short, practical guides that explain the measurements and material units behind the calculators. Each one links to the tool that does the math.
Use these guides when you want the reasoning behind a number, not just the number. They pair with the calculators: read the measuring guide before the hip tool, the squares-and-bundles guide before ordering shingles, and the framing guide before using the rafter tools.
