It is 10% building perimeter for comparing Hip to Non Hip (other than flat roof). Linear measurements.

It’s 10% of total roof area when comparing FLAT roofs. This is where you can explore over hang and slope. Area measurements.

So the garage is considered as bulding perimeter?

Yes, if it is attached to the house in any way.

If it is a detached garage, no. Typically a detached garage or other out building is not considered. These would be insured as an additional structure. You may wish to place a call to the agent to double check.

Post a pic if you want.

Where are you located?

It isn’t the building perimeter, it is the perimeter of the roof. You measure the drip edge. If the wall measures 20 feet but the home has a 1 foot overhang, the roof measurement would be 22 feet.

Likewise gable sections would be from the point where the fascia meets the other roof.

A follow up to my comment. You only measure total perimeter. If for instance there were a second story roof above a first story roof, you only measure the longest length. You do not measure the second story roof line and add it to the first floor roof.

Sorry Robert you are mistaken. Please review what is written on the 1802:

[FONT=Times New Roman][size=2]“Hip Roof: Hip roof with no other roof shapes greater than 10% of the total building perimeter.”[/size][/FONT]

Only when determining if the roof qualifies as flat, does the overhang and other roof demension including slope, figure in to determining roof shape.

[FONT=Times New Roman][size=2]“Flat Roof: Flat roof shape greater than 100 square feet or 10% of the entire roof, whichever is greater.”

The accepted standard is to measure the fascia and across the gable bottom cord to the fascia for the perimeter.
