A cant strip is a triangular-shaped piece of material used in roofing where a flat roof meets a vertical wall. It creates a gradual slope that helps water flow away from the wall and prevents sharp 90-degree angles that could damage roofing materials. Think of it as a small ramp that creates a smooth transition between the roof and wall. Cant strips can be made from various materials like wood, metal, or fiber, and they're essential for proper water drainage and extending the life of the roof. When you see this term in resumes or job descriptions, it relates to commercial or industrial roofing work.
