A roofing square is a measuring tool used by roofers to lay out rafters and frame roof pitches. It's a large, flat metal square, often with markings for common cuts and angles. I've seen carpenters use it to mark birdsmouth cuts and hip rafters. It's essential for getting the slope right and ensuring all pieces fit snugly, making the roof both functional and weathertight.
