In HVHZ zones, roof tile systems, combining mechanically fastened tile and mortar and/or adhesive shall be required for roofs greater than:

Explanation:
In HVHZ zones, roofs must resist hurricane-strength wind uplift, and the way tiles are secured changes as the roof slope gets steeper. When a roof pitch exceeds 7:12, the uplift forces become more significant, and a single method of attachment may not provide enough hold. To achieve the needed wind resistance, a hybrid system is required: mechanically fastened tiles paired with mortar and/or adhesive. The combination locks the tiles both to the substrate and to each other, giving redundancy and greater resistance to uplift during extreme winds. This is why roofs greater than 7:12 pitch must use the combined fastening approach in HVHZ areas.
