What is the minimum distance of a cant strip mentioned for basic construction at the intersection of a flat roof and wall?

The minimum distance of a cant strip at the intersection of a flat roof and wall is crucial for effective water drainage and preventing water accumulation at this vulnerable seam. A cant strip, typically sloped, helps direct water flow towards drainage points rather than allowing it to collect and potentially lead to leaks or other water-related issues.

In construction practices, a distance of 8 inches is widely recommended for cant strips, as this width provides an adequate surface area to ensure that water flows efficiently off the flat roof and onto the drainage system. It also allows for proper roofing material application and ensures that the roofing system performs optimally at the intersection of the roof and wall.

This standard helps create a reliable barrier against moisture intrusion, contributing to the overall durability and longevity of the roofing system. Adhering to the 8-inch guideline fosters best practices in roofing design and construction, significantly reducing the risk of future structural problems.
