A cant strip is ____________ in cross section.

A cant strip is typically triangular in cross-section, which is designed to facilitate drainage and prevent water accumulation on flat roofs or similar structures. This wedge-shaped geometry allows water to flow off the roof surface rather than pooling, which can lead to leaks and structural damage. The triangular design also aids in directing the runoff towards the drainage points of the roofing system, ensuring efficient water removal.

The cant strip's shape is particularly useful in areas where roofing materials transition from vertical to horizontal surfaces, as it helps create a smooth, sloped surface that enhances the integrity and durability of the roofing system. This design feature is critical in roofing applications and relates directly to ensuring the longevity and performance of the roof.
