A half-hip roof is also called a clipped gable or jerkinhead roof. It is essentially a gable roof end that has a small hip sloping backward near the peak. The Florida wind mitigation form (OIR-B1-1802) requires that a roof can only qualify as the hip roof discount if it has “no other roof shapes greater than 10% of the total roof system perimeter.” So only the small portion of the half-hip near the top that is actually a hip would count, and the gable portions at either side of center would be considered “non-hip” towards the 10% rule. 

    Although the part of a half-hip near the ridge does get credited as a hip by the standards of the form, in actuality the whole half-hip gable end has about the same structural weakness in a hurricane as a full gable end, unless braced for hurricane wind load to engineering standards inside the attic.
