What is the process of placing roofing materials end-to-end without overlapping called?

The process of placing roofing materials end-to-end without overlapping is called a "Cant Strip." Cant strips are installed at the edges of roofing systems to provide a smooth transition between two different materials or surfaces. They help to facilitate water drainage, reduce the risk of leaks, and improve the overall appearance of the roof.

This technique is essential in ensuring that water rolls off the roof smoothly and does not accumulate, which could cause damage over time. Cant strips are often used in conjunction with other roofing components to create a sound and effective roofing system. The design and application of cant strips are critical for the roof's longevity and performance, particularly in flat or low-slope roofing installations.

The other options either refer to different roofing components or processes that do not specifically describe the arrangement of roofing materials in a non-overlapping fashion.
