Question

If the "north" facing facets comprise more than 25% of the roof area, is it the intent of the Roof Section definition, to require full replacement of the roof even if only the "north" facing facets of a roof are damaged in a storm, and the remaining East, West, and South facing facets remain intact and in good condition?

While there does not appear to be a definition of what a
"facet" is related to the building code, if the north
"facet" meets the definition of a roof area, only that
section is replaced. Otherwise the entire roof covering is
replaced.

From the Florida Building Code:
ROOF SECTION. A separation or division of a roof area by
existing joints, parapet walls, flashing (excluding
valleys), difference of elevation (excluding hips and
ridges), roof type or legal description; not including the
roof area required for a proper tie-off with an existing system.

Commentary

The 25% rule still applies per Declaratory Statements issued recently by the Florida Building commission. DS 2015-135 and DS 2015-109. The Code contains the allowance which permits not more than 25 percent of the total roof area or roof section of any existing building or structure shall be repaired, replaced or recovered in any 12-month period unless the entire roofing system or roof section conforms to requirements of this code.
