Need some clarification. On the Florida Wind Mitigation report under “Roof Geometry” it says “Hip roof with no other roof shapes greater than 10% of the total roof system perimeter”. In one area this roof has a hip perimeter that goes to a flat roof about 3 ft up. Is it just a complete Hip roof or should that area be considered an “other roof shape” at that perimeter? Thanks
IMO… that’s NOT a “flat” roof… it’s a “low slope” roof. Big difference!

The 1802 form clearly states
Hip roof with no other roof shapes greater than 10% of the total roof system perimeter
I do not see that as part of the perimeter

Taken from the wind mitigation class material
When measuring the perimeter, measure around the roof as a two dimensional object, such as from an aerial view. When measuring other roof features, include non-hip features that are not part of the perimeter.
The inspector should be sure to look carefully and include all roof surfaces in calculations.Even though an inspector would find it difficult to see this roof (pictured above) from the ground, this roof was actually classified as flat.
With that said, I would think that the flat section would take away the hip on this roof.
